The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

Chapter 3 OverviewBWX 8305 Basestation Components

3.4 BWX 8305 Basestation ComponentsA Cisco BWX Mobile WiMAX system provides wireless broadband access to a core network, typically to the Internet or to any local or wide area network (LAN/WAN). When a Service Provider has established BSs in a given coverage area, the subscriber connects a BWX 110 or BWX 210 Desktop Modem to their computer (or inserts a BWX 120 PCMCIA Modem into their laptop) to access the network without the need for a professional installer.

This is what Cisco refers to when it says its system is “zero-install®”: no truck rolls, no professional installation schedule for the consumer. In fact, some Service Providers have their subscribers pick up their Modems at retail stores, or, in some cases, simply mail the Modems to the subscribers. The subscriber Modem is generally referred to as Subscriber Station(SS). The SSs can be Desktop Modems that attach via an Ethernet cable to the user’s PC, or they can be Wireless PC Cards that insert in the PCMCIA slot on a laptop computer.

In Release 7.0 Cisco offers three Subscriber Stations: the BWX 110 Desktop Modem, the BWX 210 Desktop Modem, and the BWX120 PCMCIA Modem Card. The BWX 110 Desktop Modem covers a 2 MHz frequency range and comes with a Liquid-crystal Display (LCD) front panel, that shows signal status, while the BWX 210 Desktop Modem covers a 5 MHz frequency range, has no LCD display and is simply switched on/off. The BWX 120 PCMCIA plugs into laptops for true portability to change locations easily, where coverage is available.

The entire BWX Mobile WiMAX system (Figure 3-1) has four main components: one or more Basestations, Subscriber Stations (SSs, also referred to as Modems), the Element Management System (EMS), and the Broadband Wireless Gateway (BWG). The BS portion of the system consists of the BWX 8305 Basestation, BWX 8303 Basestation Timing System, and the BWX Basestation Antenna.

Chapter 3 OverviewBWX 8305 Basestation Components

Figure 3-1 BWX Mobilw WiMAX System Components

The BS performs the conversion of RF signals to digital signals for packets transmitted uplink (SS to BS), and converts digital signals to RF signals transmitted downlink (BS to SS). The BS interfaces with the BWG and either directs traffic to/from the BWG (residential service) or tags the traffic to route to/from a private network (Business/Enterprise service). The BWX Antenna is the antenna that is mounted on a tower, rooftop, or other structure. The BS is available as a BWX 8305 Basestation or as a BWX 2305 Basestation. The BWX 8305 has an BWX Antenna with 8 antenna elements, while the BWX 2305 has 2 individual dipole antennas.

Note The BWX 8303 Basestation Timing System is required for WiMAX Basestations.

The BS uses a Global Positioning System (GPS) antenna, connected to a BWX 8303 Basestation Timing unit. The BWX 8303 Basestation Timing System (formerly known as External GPS Unit, EGU) is mandatory for BSs in all WiMAX deployments starting with Release 7.0 and subsequent releases.

For network deployments, the BS with BWX 8303 Basestation Timing System is the only supported configuration in WiMAX deployments for Release 7.0 and subsequent upgrades. Warranty and ongoing TAC support on the BS only covers BSs deployed with the supported configuration. Existing customers having BSs deployed with built-in GPS must order and install the BWX 8303 Basestation Timing System as a prerequisite prior to performing software upgrade to Release 7.0 and subsequent releases. One BWX 8303 Basestation Timing System supports up to three BSs at a cell site. Installation of the BWX 8303 Basestation Timing System must be performed by qualified personnel to preserve warranty for the BS at the same site.

For WiMAX deployments, an accurate timing system as the source of synchronization is a requirement for the BS to function properly. The BWX 8303 Basestation Timing System provides this timing source to the BS.

The maximum throughput varies by Model type and RF channel conditions.


OL-16336-02

Chapter 3 OverviewBeamforming

The EMS is a set of software applications that the Service Provider uses to configure, communicate with, and manage all the system elements directly related to the Broadband Wireless Access system. EMS provides a single point for managing BWG-toBS, BWG-to-EMS, BS, and SS communications in a WiMAX network.

The EMS is an IP-based element manager designed in a Server-Client relationship and runs on either Windows or Solaris Operating Systems. Most Service Providers use the Client EMS Configuration & Alarm Manager (CAM) application to interface with the system. All of the functions that can be performed through the CAM can also be performed through a Command Line Interface (CLI), which is a common computing language across platforms.

3.5 BeamformingCisco BWX 8305 Basestation antennas contain 8 elements (Figure 3-2), with a gain of 16 dB in the panel configuration. Their combined effect is to concentrate the downlink data into a beam with maximum gain at the location of each target SS (Figure 3-3).

Similarly, in the uplink the data transmitted by each SS is received by the 8 antenna elements with different phases due to the differences in propagation distance from an SS to each antenna element. The contributions from an SS are added up coherently after adjusting their phases for maximum gain. This effect, which we call beamforming, is equivalent to having up to 18 dB of additional gain in the downlink and up to 9 dB additional gain in the uplink. It allows the Cisco BWX Mobile WiMAX system to ate at a much lower power level than would otherwise be necessary for the same results.

Pre-installation
5.1 Personnel & ToolsReference: Appendix B, “Cisco Recommended Tools”

The BWX 8305 Basestation (BS) equipment installation itself normally takes 1-2 people only 2 days1. However, prior to installing the equipment a number of planning, acquisition, and other preparation activities take place. If these tasks are not completed before the installers show up to begin installing, then the deployment may take longer than 2 days. The planning tasks are not detailed in this guide, but information or examples for many of them are referenced and located in the appendices.

5.2 Project PlanCisco provides several options to customers for the work to be done in preparing a site for operation. The customer may have their own installation personnel, or they may hire Cisco or one of its authorized service partners to perform the installation. A project plan document that lays out the work to be done, the objectives of the project, the schedule, the resources required to complete it, and other information pertinent to the deployment needs to be developed.

5.3 RF Coverage Prediction MapReference:

• Appendix C, “RF Coverage Prediction Map Example”

• RF Sales Guide P/N: OL-16330-01

• WiMAX RF Planning Guide P/N: OL-16333-02

As part of determining which BS equipment is needed and where to place the equipment for a successful deployment, an RF Engineer (customer’s, Cisco’s, or service partner’s) will go through the process of studying the RF environment of the candidate sites that the Service Provider has identified. The RF Engineer takes readings and analyzes each site in order to predict what range of coverage may be expected. Coverage predictions take into account Basestation performance capabilities and the Service Provider’s marketing objectives. An example is shown in Appendix C, “RF Coverage Prediction Map Example.”

1. All I&C tasks can be completed by 1 person, but 2 may be desired during commissioning - one to drive and one to run the tests using a laptop computer.


Chapter 5 Pre-installationSite Candidate Evaluation

5.4 Site Candidate EvaluationReference: Appendix D, “Site Candidate Evaluation Form”

As various deployment sites are being considered, most companies use a form like the one Cisco calls the Site Candidate Evaluation form. The form, when completed properly, helps to ensure that all aspects of planning for the site have been considered. Every site is unique, and the form is filled out for each site. Doing this makes sure nothing is taken for granted or assumed about the site and whether or not it will be a successful deployment site if selected.

Cisco provides the Site Candidate Evaluation form in electronic format. The form includes fields to capture the logistics of the site, GPS coordinates, antenna mount possibilities, power availability, etc. It is from this information that a selected site will be planned and prepared for equipment installation and connections. The main page of the form is displayed in Appendix D, “Site Candidate Evaluation Form.”

This form can be found on the following LiveLink site: https://tools.cisco.com/cws/livelink?func=ll&objid=4353291&objaction=browse.

5.5 Interference AnalysisReference: Appendix E, “RF Center Frequency & Interference Analysis Guidelines”

Cisco recommends to Service Providers that they conduct an Interference Analysis of the selected site. The Interference Analysis is performed primarily to assure there is no other radiating equipment in the geographical area that might interfere with the BS operation.

5.6 Site Design & RegulatoryThe site where the BS is going to be installed must be carefully blueprinted to prepare for equipment ordering and installation. Cisco can supply product specifications and drawings to help the customer design the site. More importantly, however, is that the Service Provider of any wireless equipment must be versed in the regulatory requirements for the region. Unless operating in an unlicensed frequency, such as 2.4 GHz, the Service Provider must have a spectrum license (usually from a government regulatory body). The Service Provider is also responsible to see that communications and other regulatory standards and laws will be sufficiently met at this site.

Note WiMAX does not operate in unlicensed bands.

5.7 Network Architecture PlanReference: IP Network Planning Guide P/N: OL-16329-01

The Service Providers Network Administrator or Planner is involved with a deployment from the perspective of integrating the BS, BWG, and AAA seamlessly into the operational network. They have to plan the traffic routing, IP addressing, protocol compatibility, and how they are going to monitor BS, BWG, and AAA operation.


OL-16336-02

Chapter 5 Pre-installationRF Cable Selection

5.8 RF Cable SelectionThe size and type of cables used to install the Basestation affect power loss and calibration range for the transmitter and receiver. The Service Provider must decide which type of cable and connectors they will need and get them ordered. Cisco offers a limited number of cable types & lengths. Service Providers who have cable needs, not offered by Cisco, can purchase these cables form a Cisco approved supplier (Contact your Account Manager for further details). No matter which are chosen, all cables and connectors must meet FCC or other regulatory limits for RF, UL, and NEC/CEC. Selection guidelines are provided by Cisco based upon the frequency band and the length of the cable required between the BS and BWX 8305 Basestation antenna.

Note Use of non-Cisco approved cables can invalidate the warranty.

5.9 Bill of Materials (BoM)Whoever orders the equipment must generate the Bill of Materials (BoM), which is the actual equipment order for manufacturing and shipping to the installation site. Cisco provides the part number and prices, as well as recommendations to assist customers in the correct placement of orders. Normally, the customer will work with their Cisco Account Manager or Cisco authorized partner to complete the BoM.

5.10 Acquire Materials, Documents & FormsOnce ordered, the purchaser has to ensure that everything required for the installation is secured and at the deployment site. Cisco highly recommends inventorying the equipment arrival prior to having installers brought on-site so that they do not have to wait on parts to complete the installation. Also make sure that all necessary documents and forms that are referenced in this guide are available.

5.11 Confirm AAA, BWG, and Backhaul Network AvailabilityVerify that the AAA server, BWG, and Backhaul network are all available for connection. The backhaul connection required for the BS consists of one Ethernet cable connection with RJ-45 connectors for each BS installed. The exact quantity for each connection will depend on the site requirements. These connections need to be made available before installation begins. The Service Provider is responsible for compliance to all regulatory limitations related to the backhaul network and connections.

5.12 Confirm FTP & BWX EMS Server ReadinessThe Service Provider should put into place an FTP server and the BWX EMS Server platform prior to the installation crew’s arrival at site. If the customer’s BWX EMS Server is not available until after installation begins, the crew will use a laptop to perform initial configuration tasks. The FTP server, however, must be in place in order to commission the Basestation.


OL-16336-02

Chapter 5 Pre-installationConfirm Mounting Rack or Outdoor Enclosure Availability

5.13 Confirm Mounting Rack or Outdoor Enclosure AvailabilityReference: Appendix F, “BWX 8305 Basestation Outdoor Enclosure Manufacturers”

If the BS will be housed inside a building, it is typically mounted in a standard 19- or 23-inch rack. Rack adapters are needed to mount the equipment in a standard 23-inch rack. If the BS will be housed outdoors, the Service Provider must select and make ready an outdoor enclosure. The Service Provider can supply an outdoor enclosure from any one of a multitude of vendors. Please refer to Appendix F, “BWX 8305 Basestation Outdoor Enclosure Manufacturers” for recommended manufacturers.

5.13.1 AccessibilityBS equipment is required to be installed in a restricted access location, in accordance with NEC/CEC standards. Only authorized personnel should have access to this equipment.

5.14 Confirm Power & Grounding ReadinessThe BS can be ordered with one of the following power inputs:

• + 24 VDC

• - 48 VDC

• 100/240, 47/63 Hz VAC

The Service Provider is responsible for providing earth grounding and for meeting all regulatory standards related to power and grounding.

5.14.1 Power RequirementsPlease refer to the Technical Specifications for power requirements. When - 48 VDC or +24 VDC input power is used, the BS must be connected to a power supply/rectifier that is IEC 60950-1 certified (UL listed to UL60950-1 in North America) and have a ground SELV output. It must be installed in accordance with NEC/CEC Articles 800/810/830. A UL listed disconnect device, such as a circuit breaker or fuse, must be installed between the power supply and the BS chassis connections.


OL-16336-02

Chapter 5 Pre-installationConfirm Power & Grounding Readiness

Note External power source / supply considerations for the - 48V and + 24V BS chassis: a. An external method of disconnecting each of the DC power Load/Return lines to the BS chassis is required, either through fuse+disconnect device(s) or a dual-pole breaker. The fuse/breaker rating must be minimum 10% higher than that of the BS Chassis breaker but shall not exceed 70A. b. The external DC power source, if current limited, shall have the limit set-point configured higher than the BS Chassis breaker rating. c. The external supply "Return" and the BS chassis shall be bonded to a common Earth ground. The BS Chassis has an external ground lug provided. d. Do not remove protective earth connection before disconnecting the BS from the DC power supply.

5.14.2 Grounding RequirementsThe BS requires an earth ground connection. Grounding from copper point to copper point shall be less than 1 ohm. Grounding from copper point to earth ground shall be less than 5 ohms. All power and grounding conductors must be mechanically supported to avoid strain of the wires and connection points. AWG #6 is used between the equipment and the bus bar, and AWG #2 is required from the bus bar to the earth ground. Always refer to the regulatory standards for power and grounding.

5.14.3 Lightning ProtectionEvery BS automatically comes with Secondary (built-in) lightning protection. The Service Provider should purchase Primary lightning protection (available from Cisco). Lightning protection helps to protect the BWX Basestation Antenna, BS, and RF lines against tower lightning events occurring at the BS. While not absolute, the Primary protection greatly reduces the possibility of damage to the equipment.

Note Cisco does not warrant equipment damaged by lightning (direct or indirect).

Figure 5-1 below shows a BS with both Primary and Secondary surge protection, which is the recommended configuration. In addition to tower lightning events occurring at the BS, lightning events that occur miles away from the BS can generate intense electrical currents traveling over the power and/or backhaul lines and into the BS equipment, damaging it. For this reason, Cisco strongly recommends adding the primary surge protection as well as surge protection devices at the power and backhaul demarcation points.

Installation
6.1 InventoryReference: Appendix G, “Closeout Tool Form & Procedure”

The first thing an installer physically does once onsite is to check to see that all equipment and materials have arrived, as well as to make sure all necessary documents and forms are available. This is when the installer will first work with the Cisco Closeout Tool by entering the site information for the BS components. The Closeout Tool is an Excel spreadsheet with linked worksheets and calculations to automate the system deployment information. The Closeout Tool is explained under the next heading in this chapter.

Note The installer and/or customer should keep a copy of the collected data/Closeout Tool form for future reference.

As you inventory the BWX 8305 Basestation (BS) components, check to ensure the following attachments are visible:

• Manufacturing printout sheet attached to the BWX 8305 Basestation Antenna, showing the antenna insertion loss or gain values in the transmit and receive direction at the lower, middle, and higher frequencies (Figure 6-1).

• Compact disk (or other media) attached to BWX 8305 Basestation Antenna (Figure 6-1). It contains the antenna configuration data specific to that BWX 8305 Basestation Antenna.

• Manufacturing printout sheet attached to the bundled RF cables (RG-6 or RG-11). This sheet contains the cable loss values for the bundled cable. These values will be entered in the Closeout Tool. These data are specific to each bundled cable.

Do not try to use former values, i.e., from a previous site, for any of the above three items. Each measurement is unique to that piece of equipment and must be entered exactly as stated for this deployment.

6.2 WiMAX I&C Closeout ToolReference:

• Appendix G, “Closeout Tool Form & Procedure” or

• WiMAX I&C Closeout Tool & Procedure

The Cisco Closeout Tool is a collection of linked forms with spreadsheet formulas used to capture and provide important information for each Basestation deployment. The information captured by this tool is not only used to help verify proper commissioning of the system during acceptance testing of the site, but it is also used for later troubleshooting if there are problems.

Keep the Closeout Tool open on your computer during the installation and commissioning of the system (you can minimize). You will mostly be recording data into the green-colored fields in the various worksheets found in the tool. At this time, select the first worksheet, “Company Info”. Fill in the company name, BS name, and the remaining green fields (Figure 6-2). Fill in the information from the Regulatory Label attached to the bottom of the BS unit.

Later, you will use the “Read BTS Export File (.txt)” button to populate the yellow fields with BSn configuration data that is exported from the EMS into a text file. After you complete all of the green fields, click on “Save Workbook” to save this file. Remember to save the workbook after you make your entries.

Check all regulatory requirements prior to installing the BWX 8305 Basestation Antenna.

6.3.1 DescriptionThe BWX 8305 Basestation Antenna is the part of the BSn that contains the Power Amplifiers (PAs), the 8 antenna elements, and, depending on frequency and customer choice, Channel Filters and Low Noise Amplifiers (LNAs). A BWX8305 Basestation Antenna radiates 120 degrees (Figure 6-3). The use of Channel Filters in a BWX 8305 Basestation Antenna is optional. These filters are installed inside the BWX 8305 Basestation Antenna, which is shipped separately from the BS.

Figure 6-3 BWX 8305 Basestation Antenna

Note The 8 element BWX 8305 Basestation Antenna has 6 degrees of fixed electrical downtilt.

6.3.1.1 Filters

In the BWX 8305 Basestation Antenna you have the option to:

• 1- Use a Band filter: The Band filter is of the Cavity type. The Channel filter is also of the cavity type but with a Dielectric Resonant Oscillator (DRO) “puck” placed in the cavity to improve performance. Frequently, the words “Cavity filter” are used in conjunction with the Band filter. The functions of the Band filter are two-fold: (1) to shape the out-of-band emission (e.g., L.O. Linkage, harmonics, and other spurious emissions) during transmission in order to meet Federal Communications Commission (FCC) or other regulatory requirements; (2) to provide rejection for close-in interference (e.g., Personal Communication Systems/Advanced Mobile Phone System(PCS/AMPS) and other cellular services, television (TV), and Radar) during the receive period (i.e., improve the receiver selectivity). The Band filter has a wider passband than that of a Channel filter (e.g., BW= 15 MHz separating the Wireless Communications Service (WCS) from Digital Audio Radio Service (DARS) frequencies).


OL-16336-02


• 2- Use a Channel filter: The functions of Channel filter are two-fold: (1) to shape the power amplifier out-of-band emission during transmission in order to meet FCC or other regulatory requirements; and (2) to provide high rejection for close-in jammers during the receive period. The latter improves receiver selectivity. As indicated by its name, the Channel filter operates in a specific limited frequency band (e.g., Bandwidth (BW) = 5 MHz) and has more stringent attenuation requirements. Normally, the attenuation is 15-20 dB rejection for close-in frequencies. Additionally, while a Band filter attenuation drop off is slower than that of a Channel filter, it has much higher attenuation at frequencies removed from the central frequency (e.g., 60 dB).

• 3- Not use a filter at all

If a BWX 8305 Basestation Antenna has Channel Filters installed, it must be operated at a center frequency that exactly matches the center frequency for which the Channel Filters were manufactured; otherwise, the equipment could be damaged. If no Channel Filters are installed, the Service Provider is free to select or change the center frequency of the BS without damaging the equipment.

Note Depending on the country where the system is being used, a Channel filter or a Band filter or no filter may be needed to meet the spectrum requirements of that region. In general, the cost associated with a Channel filter is 3-5 times more than that of a Band filter - a consideration to keep in mind when addressing a deployment for a specific region.

Note If the Channel Filters do not come installed and you have to install them, please refer to Appendix H, “BWX Antenna Channel Filter Installation Procedure” for the procedure to do so.

Note If you are required to paint the BWX 8305 Basestation Antenna, for example because of environmental aesthetics, please refer to Appendix I, “Guidelines for Painting a Cisco Antenna.”

6.3.1.2 High-powered BWX 8305 Basestation Antenna

The High-powered BWX 8305 Basestation Antenna unit operates in the 3475 to 3610 MHz range. This antenna is intended for use with an BWX 8326 Basestation Combiner unit (which allows 2 Basestations to share one antenna), but can also be used by a single Basestation to increase capacity. The High-powered BWX 8305 Basestation Antenna yields 3 dB more than the Standard BWX 8305 Basestation Antenna antenna. See Appendix J, “High-Powered BWX Basestation Antenna” for more information on the High-powered BWX 8305 Basestation Antenna, and Appendix K, “BWX 8326 Basestation Combiner (3400 to 3625 MHz)” for information on the BWX 8326 Basestation Combiner

6.3.2 Handling the BWX 8305 Basestation AntennaIt is a good idea to inspect the exterior of the BWX 8305 Basestation Antenna for any damage that may have occurred during shipping, prior to placing it at the target site. Each of the antenna elements in the BWX Basestation Antenna are covered by the individual radomes on the panel. At all times handle the antenna carefully. If, during storage, filter replacement, or PA replacement, you must place a panel antenna in a position laying down, make sure it rests flat on at least one inch of plastic foam to prevent damage to the antenna elements.


OL-16336-02


When you are ready to place the antenna into position, it should be lifted using multiple lift points. Place two non-metallic slings around the BWX 8305 Basestation Antenna, and attach the slings to the hoist, as shown in Figure 6-4. Never use the radomes to lift, support, or otherwise bear partial or full weight of the BWX 8305 Basestation Antenna. Doing so can cause damage to the radomes. Use two ground-anchor lines attached to the lower screws of the mount to steer the BWX 8305 Basestation Antenna and prevent it from spinning or swaying in the wind and perhaps hitting the tower or other nearby structures with the radomes.

Figure 6-4 Lifting the BWX 8305 Basestation Antenna

6.3.3 Power & Grounding

6.3.3.1 Lightning Protection

Lightning protection information is covered in Chapter 5, “Pre-installation.” Please review that section before continuing with the installation process.

6.3.3.2 Surge arrestors

There are two basic types of surge protectors (devices that block lightning surges and electrical transients) on the RF cables - those that allow a DC current to pass through, and those that block a DC current. The first type (allowing a DC current to pass) contains gas discharge tubes. The arrestors provide bi-directional protection for lightning; they have no designated equipment side or line side. The other type (blocking DC current) has a surge side and a protected side. They are unidirectional and must be installed accordingly.

There are several companies providing surge arrestors. Figure 6-5 shows two examples.


OL-16336-02


Figure 6-5 Examples of RF Cable Surge Arrestors

Note Make sure that the surge protectors are not too large for the weatherproof “boot” on the antenna install.

6.3.3.3 Antenna Ground Bus Bar Installation Procedure

You will install the Antenna Ground Bus Bar on the mounting structure, per accepted Telecom standards and procedures (Figure 6-6). The location is determined during site design and should be close to the BWX 8305 Basestation Antenna. Two or more bus bars may be installed per system.

Figure 6-6 BWX 8305 Basestation & Antenna Ground Bus Bars

6.3.3.4 System Ground Wiring

Install the system ground as a single point connection between the system ground bus bars, the BWX 8305 unit, the BWX8305 mounting rack, and the BWX 8305 Basestation Antenna. Connect the system ground to earth ground. AWG #6 is used between the equipment and the bus bar, and AWG #2 is used from the bus bar to the earth ground. Always refer to the regulatory standards for power and grounding. Apply anti-oxidant joint compound to all connections (Figure 6-7). Tighten all connections until secure.

6.3.4 Antenna SeperationWhen installing multiple BSs in the same geographical area, it is important to allow enough radiation separation so that they do not interfere with one another. Figure 6-8 provides some general guidelines for avoiding adjacent interference. The illustration shows the horizontal and vertical separation in feet and in meters for panel antennas.

Caution There can be no co-location of MC-SCDMA with Mobile WiMAX Basestations. If 2 or more BSs are co-located on the same structure, they must run the same technology or be upgraded in the same maintenance window. Use frequency separation to minimize interference between a MC-SCDMA and Mobile WiMAX Basestation. A reasonable frequency separation is 15 MHz for BSs that are 2 kilometers apart. The exact frequency separation may differ on a case-by-case basis. Therefore, 15 MHz with 2 kilometers between Basestations may not provide enough separation. Refer to the BWX Mobile WiMAX Migration Planning Guide for more information on distance requirements.

Caution All BSs in a network must have the same DL/UL symbol ratio. The default recommended ratio is 32/15. Cisco does not support basestations that use different DL/UL symbol ratios in the same area because they will interfere with each other. Please refer to the BWX EMS Configuration Guide for more information on parameter settings.

6.3.4.2 Vertical Separation – Cisco to Cisco

A minimum of 3 ft separation in the vertical axis is required between any two Cisco antennas (Figure 6-10). This separation is needed to obtain proper and optimum results from each antenna.

Figure 6-10 Vertical Separation (Cisco to Cisco)

6.3.4.3 Horizontal Separation – Cisco to Another Vendor

A minimum of 10 ft horizontal separation is required between a Cisco antenna and another vendor’s antenna (Figure 6-11).

Figure 6-11 Horizontal Separation (Cisco to Another Vendor’s Antenna)


OL-16336-02


6.3.4.4 Horizontal Separation – Cisco to Cisco

A minimum of 3 ft of separation between Cisco Panel antennas is required.

6.3.4.5 No Antenna Zone

If a vertical and horizontal cone extends 15 ft in front of a 120° Panel antenna, this lessens the 10 ft horizontal and vertical requirements for the placement of the antennas (Figure 6-12). By using these lesser requirements, the Service Provider accepts some limitations:

• Signal reflection from the antenna or obstruction

• Shadowing or dead zone in coverage caused by antenna or obstruction

• The amount of reflection and shadowing is affected by the size of the antenna or obstruction

6.3.6 Set the DowntiltBased on coverage objectives determined by previous RF planning, the BWX 8305 Basestation Antenna may need adjusting upward or downward once mounted on the pole, tower, roof, building, or other structure. The panel antenna has a -6° built-in electrical downtilt.

You will use an inclinometer to read the mounted position and to determine what adjustments, if any, need to be made. For example, if the inclinometer reads +2° (uptilt) and you are mounting a panel BWX 8305 Basestation Antenna, the resulting beam has a –4° downtilt (Figure 6-14). The downtilt can be adjusted per the assembly shown in Figure 6-15.

6.3.7 Antenna OrientationThe magnetic declination, which is the angular difference between observed magnetic north on a compass and geographic (or “true”) north, shifts from year to year. Panel antennas must be oriented appropriately as required by the RF plan.

Adjustments that will need to be made are based on the Magnetic Declination Chart (Figure 6-16), which provides values to correct the compass reading and determine the true geographic East. Always check for the latest chart information, which may be found at the following web address: www.thecompassstore.com/decvar.html.

Since this is not the year 2000 any more, you will want to check this reference chart to learn how your magnetic declination may have shifted since then. Notice that the map measures annual shifts in minutes. Since it takes 60 minutes to equal 1 degree, if you notice that your location has a declination shift of 5 minutes per year, this means it will be another 12 years before your declination adjustment changes by one whole degree.

Figure 6-16 Magnetic Declination Chart – Example

Note It is better to convert the “true” azimuth (which way the antenna should point in the horizontal plane) as required by the RF Plan to the magnetic value that will be read on the compass before sending the installer to the field. This way the installer will go by the reading on the compass, not having to worry about magnetic declination corrections.

6.3.8 Record Cable Loss and BWX 8305 Basestation Antenna Data in the Closeout Tool

6.3.8.1 RF Cable Sweeps

At this time, sweep each cable (including Cal cable) according to the following procedure.

Step 1 Connect the Signal Generator directly to the Spectrum Analyzer using a barrel connector.

Step 2 In the Signal Generator:

a. Set the Center Frequency to the desired value.

Step 3 In the Spectrum Analyzer:

a. Set the Center Frequency to the same value as in the Signal Generator.

b. Set the Span to 5 MHz.

c. Set both the Resolution Bandwidth and the Video Bandwidth to 100 KHz.

d. Verify that the Sweep is set to "Auto".

e. Press the Amplitude button and rotate the wheel until you can see the peak of the signal.

f. Set the Marker to the peak of the signal.

Step 4 In the Signal Generator:

a. Adjust the level of the signal until you read 0.0 dBm in the Spectrum Analyzer screen.

Step 5 Insert the cable to be measured and read the insertion loss in the Spectrum Analyzer window. Compare the Spectrum Analyzer value to the printed tag that came with the cables. If there is a large discrepancy between the numbers, check the connectors and re-sweep. Repeat the process at the frequencies above and below your center frequency (marked “High” and “Low” on the cable sticker). Sweep all cables and jumpers.

6.3.8.2 Enter BWX 8305 Basestation Antenna Data

The CD that accompanies the antenna contains an HTML file (under the RFS folder).

Open the WiMAX I&C closeout Tool (should be open from the Cable Sweeps). Click on the “RFS and Cable RFS loss” tab. Press the “Insert RFS data” button. When prompted to open a file, find the HTML file under the RFS folder in the CD, and click “Open”. This will automatically populate the top half of the tab. See Figure 6-17.

6.3.9 Connect Bundled Cables to BWX 8305 Basestation Antenna

6.3.9.1 Types of Cable

All BS cable connections are made using standard RF coaxial cable. In Figure 6-18 are examples of various coaxial cables sold in the United States. Note that the RG-6 or RG-11 bundled cable contains 8 antenna element cables and a Calibration (“Cal”) cable. Reducing several single cables into one bundled cable makes installation easier and helps eliminate power loss through the cables.

The bundled cable comes with a weatherized boot and 9 N-type connectors in place. At the other end the connectors can be N-type if the cables are to be connected to surge protectors in the bus bar (Primary Surge Protection), or QMA-type connectors if the cables are to be connected directly to the BS (Secondary Protection only). Examples are shown in Figure 6-19. In the first case, N-type to QMA-type jumper cables are needed to connect the surge protectors in the bus bar to the BS.

6.3.10 Sweep the BWX 8305 Basestation Antenna

6.3.10.1 Purpose

Once the BWX 8305 Basestation Antenna and bundled RF cables are installed, you must perform a sweep on the mounted BWX 8305 Basestation Antenna and connected cables. These will be swept for power loss associated with both the transmit and receive signal. For this measurement you will need a Cisco proprietary tool called the BWX Basestation Antenna Test Box. The sweep procedure is different for the transmit and receive paths. In all cases you first establish a reference level, then measure the path gain or loss test.

6.4 BWX 8305 Basestation Installation

6.4.1 OverviewThe BS is a lightweight unit that fits easily into standard Telecom racks. All connectors and indicators on the BS are on the faceplate (Figure 6-24). Inside the unit are two cards: Digital and RF. Note that the two cards inside the BS are not field replaceable. Therefore, if a severe Fault occurs, the entire unit is removed and replaced. The design intent is to cut down on the time it takes to troubleshoot or otherwise have a field support person onsite.

Figure 6-24 BWX 8305 Basestation Faceplate

The Console Port, Ethernet Port, 8 RF Ports, Cal Port, GPS Port, Power, and Grounding connectors are located on the faceplate. There are also five LED indicators at the top middle of the faceplate.

• The Power indicator is lit when the power is on.

• The Booting indicator flashes when the system is booting up, and it turns off when booting is complete. The middle light, the Fault indicator, will flash red if there is a hardware fault, such as operating temperature out of range or an antenna path is not functioning.

• The RF indicator indicates that one or more RF antenna paths are turned on and radiating energy.

• Lastly, the GPS Lock indicator on the far right is lit to indicate that the BS is locked to its timing source - the BWX 8303 Basestation Timing System.

At no time should a field person remove the back of the unit or otherwise open it. In fact, doing so may void the warranty.

Cisco recommends 5% spares planning for BS.

6.4.3.2 External Power Source / Supply Considerations

Note the following considerations for the - 48V and + 24V BS chassis:

a. An external method of disconnecting each of the DC power Load/Return lines to the BS chassis is required, either through fuse + disconnect device(s) or a dual-pole breaker. The fuse/breaker rating must be minimum 10% higher than that of the BS Chassis breaker but shall not exceed 70A.

b. The external DC power source, if current limited, shall have the limit set-point configured higher than the BS Chassis breaker rating.

c. The external supply "Return" and the BS chassis shall be bonded to a common Earth ground. The BS Chassis has an external ground lug provided.

d. Do not remove protective earth connection before disconnecting the Basestation from the DC power supply.

6.4.3.3 BWX 8305 Ground Bus Bar Installation Procedure

Prior to connecting power and grounding to the equipment, be sure to check all regulatory requirements. Follow accepted Telecom standards and procedures to connect input power and grounding to the BS. The gauge of the wire is determined by the length of the run and by NEC/CEC standards (refer to Regulatory information in the front of this document). Use a 60-amp circuit breaker when running the line. Terminate both of the input power wires and the ground wire with a ¼-inch terminal lug.

Warning Ensure that the power is off before connecting the input power wires to the BS input terminals.

Warning The power supply range must meet specifications for BS components.

Install the rubber gasket into the groove in the surge protector:

a. Install the surge protector in the system ground bus bar with the surge side toward the antenna and the protected side toward the BS.

b. Install the star washer and nut on the top of the surge protector. Torque the nut to 140-150 inch-pounds.

6.4.3.4 Install Jumper Cables

Next, install the jumper cables from the lower bus bar to the Basestation.

6.4.3.5 System Ground Wiring

Install the system ground as a single point connection between the system ground bus bars, the BS unit, the BS mounting rack, and the BWX 8305 Basestation Antenna. Connect the system ground to earth ground. AWG #6 is used between the equipment and the bus bar, and AWG #2 is used from the bus bar to the earth ground. Always refer to the regulatory standards for power and grounding. Apply anti-oxidant joint compound to all connections (Figure 6-26). Tighten all connections until secure.


OL-16336-02


Figure 6-26 Apply Anti-oxidant Joint Compound

To protect against corrosion, the Installer should apply an anti-corrosive compound to each connection point (Figure 6-27). This is especially necessary for the BWX 8305 Basestation Antenna connections due to climate effects. For the power and grounding cables, also look at Figure 6-28 concerning the use of heat shrink tubes.

Chapter 6 InstallationConnect BWX 8303 Basestation Timing System

6.4.4 Install Basestation Unit

Warning Ensure that the power to the BS unit is OFF before installing the unit in a rack or cabinet.

Place the BS unit into a standard 19” or 23” rack or outdoor enclosure. Once installed, go ahead to the next section of this Guide and install the BWX 8303 Basestation Timing System. After the BWX 8303 Basestation Timing System is installed and its cables swept, you will return to the remaining BS installation. Please note that the BS does not have an air filter option like its predecessor BS.

Caution The RF ports on the BS output a +24 VDC current, which is carried to the BWX 8305 Basestation Antenna through RF cables. This DC current may damage test equipment connected directly to the RF ports or to the end of the RF cables at the BWX 8305 Basestation Antenna. When connecting test equipment to the output of an RF port, an external DC block may be required. Most signal generators and spectrum analyzers cannot handle DC voltage on the I/O ports. Please, read the caution stickers on the equipment and provide a DC block if the equipment cannot handle over zero (0) VDC.

6.5 Connect BWX 8303 Basestation Timing SystemReference: BWX 8303 Basestation Timing System Operation & Maintenance Manual

Note The BWX 8303 Basestation Timing System is required for WiMAX Basestations.

6.5.1 OverviewThe BWX 8303 Basestation Timing System is a new feature with BWX 8305 Basestations supporting WiMAX certification requirements for high-resolution timing. The ports on the BWX 8303 Basestation Timing System provide 1 pulse per second (1 PPS) and 10 MHz source.

For the BS to be WiMAX certified, the BWX 8303 Basestation Timing System provides very precise frequency timing to the BS. The BWX 8303 Basestation Timing System receives the timing signal from the GPS antenna and outputs a 1 pulse per second (PPS) signal, along with an extremely accurate (< 0.02 ppm) 10 MHz reference signal that is locked to the GPS timing. This timing reference is then utilized by the BS to derive the carrier frequency (2500 MHz, for example) and synchronize its TDD framing to other Basestations. This Synchronized signaling is important for avoiding interference from co-located or adjacent BSs. Also, when using the Cisco BWX WiMAX Diagnostics tool, having GPS timing also permits the system to determine a user’s location via triangulation.

One BWX 8303 Basestation Timing System can provide the required reference signals for up to three BSs; thus, a single BWX 8303 Basestation Timing System is required for a tri-sectored site.

Note The BWX 8303 Basestation Timing System unit described here handles the more precise frequency referencing required for WiMAX mobility, and has its own GPS antenna port. Therefore, the GPS port from the BS faceplate is not needed for a GPS antenna.


OL-16336-02


The BWX 8303 Basestation Timing System chassis is 1.75” H x 17” W (19” with rack ears) x 12” D. The chassis weighs less than 10 pounds. The unit is available with standard 100 to 240 VAC power input and optional + 24 or - 48 VDC input. BWX 8303 Basestation Timing System status is reported via front panel LEDs for Power, Lock, and Fault indicators. Standard Ethernet RJ-45 and RS-232 ports are also available for monitoring and control using http or telnet protocols. SNMP is included in the BWX 8303 Basestation Timing System. Figure 6-29 through Figure 6-31 show the installation capabilities.

Chapter 6 InstallationAuthentication, Authorization, and Accounting (AAA) Server Installation

6.8 Authentication, Authorization, and Accounting (AAA) Server Installation

As part of the WiMAX Profile C architecture, the AAA server is a key element providing subscriber and device authentication as well as configuration. The BWG communicates using RADIUS with the AAA server for subscriber/device authentication and configuration. The configuration information is then relayed by the BWG to the BS using the R6 interface.

Cisco’s BWG open architecture design makes it compatible with any AAA server that also uses open architecture protocols. In Release 7.0, all subscriber configuration information is captured in an AAA database.

As a subscriber attempts to access the network, the SS communicates with the BS. The BS contacts the BWG which in turn interfaces with the AAA database to check authentication and authorization and to acquire the subscriber’s profile. Assuming the subscriber’s data exists and the subscriber is approved for network access, the BWG sends the information to the BS to provide service to the subscriber.

Cisco offers its own AAA application called the Cisco Access Registrar, or CAR, as part of the WiMAX end-to-end solution (Figure 6-36).

Figure 6-36 Cisco Access Registrar

For information on installing the CAR, refer to the following links:

• BWX EMS Software Installation Guide

• BWX Mobile WiMAX Configuration Guide

7.1.1 ‘Setup the ‘Test’ EMSBefore installing the EMS software on a local computer, it is a good idea to check the customer’s network architecture plan. You should review the plan against the actual setup at the site, checking to see that all equipment and software are installed and available for use. Verify that all routers are installed and IP addresses are correct.

You will need a “test” EMS computer in order to enter some basic configuration data needed to test the system once it is powered on. As an installer, you can either use a laptop computer or the customer’s intended EMS Server. (If you use the customer’s intended EMS Server, it will be connected through the backhaul, which is an Ethernet connection between the BWX 8305 Basestation (BS) and the Service Provider’s network.)

Typically, in order to keep a constant link, a 10/100 Base-T Ethernet hub or switch connects the test EMS to the BS Data port using an Ethernet cable. This allows the technician to use the EMS Client to communicate with the EMS Server, which are installed on the same test computer (instructions later in this chapter).

An RS-232 serial cable is then connected between the test EMS and the Console port on the BS. Using standard communication software -- i.e., a terminal emulation program, such as Windows HyperTerm or TeraTerm -- allows the installer to enter basic configuration data at this early stage. The procedure for setting up the communications software is described below.


Chapter 7 CommissioningInstall the Element Management System (EMS)

7.1.2 Setting Up Direct Communications Software

Step 1 Verify all RF cables going to the BS are securely connected to the proper ports.

Step 2 Connect an Ethernet cable between a hub or switch and the Data port on the BS. Connect another Ethernet cable from the Ethernet hub to the Ethernet connector on the PC that will be used as the test EMS.

Step 3 Connect an RS-232 cable (DB-9 male to female) to the Console port (UART) located on the BS and to the serial port connector on the test EMS computer.

Note A VT 100 terminal or any standard Windows-based ASCII terminal emulation program can be used for connecting to the Console port. The connection for HyperTerm is explained here as an illustrative example. The steps to get to the HyperTerm program may be different due to variances between Operating Systems and in the PC setup. There have been cases of extra “garbage” data while using the HyperTerm program. The preferred TeraTerm program can be downloaded free from the Internet.

Step 4 Power on the test EMS Server.

Step 5 On the desktop, go to Start > Programs > Accessories > HyperTerminal > HyperTerminal, using whichever terminal emulation program you are running.

Step 6 In the COM1 Properties window (Figure 7-1), under the Port settings tab enter the configuration options. Click “OK”.

Figure 7-3 BWX EMS Server & Client Applications

Note When connecting the BS equipment to the backhaul, refer to the Regulatory Information in this document, specifically regarding cabling to Ethernet connections. Ethernet connections require a UL497B listed protection device to be installed between the BS and the first network device.

7.1.3.2 Start the BWX EMS Server

This section assumes that the EMS Server & Client applications have already been loaded. The EMS software installation was described in the previous section. Please refer to the BWX EMS Software Installation Guide for detailed instructions on starting the EMS server. The default user name and password are “emsAdmin” (case sensitive). Cisco recommends always changing the default password. Verify the new password requirement with the customer. After the software files have successfully loaded, start the EMS Server by performing the following steps:

Step 1 BEFORE starting the EMS Server, open the EMS Admin CLI application and type enable. After enable is entered, you are prompted for a password. The default password is “emsAdmin”. The password will be invisible as you type it.

Next, type migratedb. Once the message stating “Database migration succeeded” displays, exit EMS Admin CLI.

Note If the migration step is run again, you will see the following message: “No Migration Needed, Database and Application Versions are both 3.”

Step 2 On the test EMS Server, double-click on the EMS Server icon to start the EMS Server application. Allow time for the EMS Server startup procedure to execute. Look for “EMS Server: UP” to scroll by in the EMS Server window to confirm that the Server is up and running. If the EMS Server does not start, call Cisco TAC (1-800-553-2447).

The resulting EMS Server window must remain open to keep the EMS Server running. It can be minimized during Server operation.

Warning Note that the EMS Server window should not be closed during Server operations, but it can be minimized. If the EMS Server ever needs to be stopped, do not click on the “X” in the top right-hand corner of the window. Instead, open a command prompt window, enter the “stopemsserver” command followed by the administrator user id and then enter the password and return, as shown in Figure 7-4.

Please refer to the BWX Mobile WiMAX Configuration Guide for instructions on the configuration of the EMS server. The configuration of the EMS server includes the following elements:

• General configuration

• Alarm Management configuration

• Performance Management configuration

7.1.3.3.1 General Configuration

General configuration of the EMS server includes changing the EMS ID & Network ID fields, entering the FTP user name, password & FTP server root path, and entering the BTS/CPE SW Directory.

Note The software upgrade files for BSs and Subscriber Stations (SSs) must be stored on the same PC where the EMS Server was installed. An FTP server must also be installed on that same PC. Under the FTP server you must add a user, give this user a password, and assign this user a root directory. Under the EMS tab, this user, password, and root directory must be specified during configuration. To do an upgrade, the file(s) are placed on that directory, and the process is initiated on the EMS, which communicates with the FTP server (which is the one that does the actual transfer). EMS Server/Client upgrades are done directly from the Cisco supplied CD. Refer to Figure 7-5.

Chapter 7 CommissioningAdd and Configure a BWX 8305 Basestation

The EMS configures in the BWG all information relative to service level agreements (service flows, packet classifiers, quality of service, user groups, VRFs, etc.) and the definition of AAA services. EMS initiated BWG configuration is only written into memory. To make configurations non-volatile, they must be saved with the BWG Action command “Commit to BWG”.

The EMS does not configure Layer 3 information, such as physical and logical interfaces, and routing. These must be configured manually in the BWG.

7.3 Add and Configure a BWX 8305 Basestation

7.3.1 Minimum System Configuration RequirementsDuring deployment of a system, only the minimum EMS, BS, SS, BWG, and global parameters must be entered to get the system up and running for testing before turning the site over to the Service Provider. The Service Provider may ask you to do more, but in this section we go over the EMS fields that must be configured in order to complete the commissioning of the system.

At this stage, you should have already installed the EMS Server and Client applications, rebooted the Server computer (which executed the “configserver” batch file), and added the BWG. The following list is typical information you will need to know to enter the minimum configuration data.

• Network ID – This is a unique identifier for a given Service Provider’s network. No other Service Provider will have the same Network ID (NID). The NID is provided by Cisco.

• BTS Name and ID – Each BS must have a unique name and number identifier. The ID can be a mix of alpha and numeric characters. Cisco recommends entering BWX or another identifier so that other personnel will later be able to recognize this BS as a BWX system.

• BTS IP Address – When you enter the IP address for the BS, the system will automatically create a second IP address for that BWX 8305 Basestation. For example, if you enter 10.10.10.1, the EMS software generates the second IP address as 10.10.10.2. The initial IP address is usually obtained from the Service Provider’s network administrator.

• EMS Server IP Address – Obtained from the Service Provider’s network administrator (for testing purposes, use the IP address of the PC where the Test EMS resides)

• BTS Subnet Mask – Obtained from the Service Provider’s network administrator

• BTS Gateway IP Address – Obtained from the Service Provider’s network administrator

• BTS Center Frequency – Obtained from the RF Plan

• Basestation Antenna Power, RX Sensitivity determined by Specifications.

• Active or Passive Antenna identified

• Cable Loss Values – RF and Cal cable

• Power Splitter Values – Obtained from the disk attached to the BWX Basestation Antenna

• Antenna Weight (W0) Values – Obtained from the disk attached to the BWX Basestation Antenna

• Whenever you define a new element (BS or SS) in the EMS database, you first add the element, then configure it by completing various fields through the EMS CAM application. Please refer to the Cisco OS Release Notes and the BWX Mobile WiMAX Configuration Guide for more datafill information.

7.3.3.7 Edit and Run the BWX Basestation Antenna Script

The electrical characteristics of each individual BWX Basestation Antenna are measured in the lab at different frequencies. These measurements are put on a compact disk in the form of CLI Scripts so that they can be loaded in the BS record corresponding to the BS with which this BWX Basestation Antenna is used. This RFS Configuration disk accompanies the BWX Basestation Antenna equipment when it is shipped.

OL-16336-02


The disk includes an RFS script and a Quick Guide with procedures for selecting the appropriate power splitter loss values and W0 values defining the geometry of the antenna to be entered into the EMS database for this piece of equipment. Each configuration disk is unique to the individual BWX Basestation Antenna that is shipped; therefore, you cannot use the same disk on other BWX Basestation Antenna equipment.

To load these values into the EMS database, perform the following steps.

Step 1 Insert the RFS Configuration disk into the CD-ROM drive of the test EMS computer.

Step 2 Copy the folder named “RFS” that is on the disk to the test EMS Server:C:\CiscoEMS\scripts.

Figure 7-35 Copying the RFS Script

Step 3 Open the new folder on the EMS Server. You will see a list of file names. The format of the file name is as follows: RFS_serial number_frequency.cli.

Example:RFS_024300001_2402500.cli RFS with serial number 024300001 and a center frequency of 2.4025 GHz.

Verify the correct serial number in the file name against the serial number of the BWX Basestation Antenna equipment. The equipment serial number may be found on the back of the BWX Basestation Antenna panel. Determine which file you need to run based on the provisioned frequency of your BS.

Note Select the frequency that is closest to your provisioned center frequency. To find the provisioned center frequency for your BS, open the EMS CAM (GUI), select the BTS tab, and highlight the specific BS. Next, click on Air Interface > Layer 2 > Carrier Data > Show Configuration. This will display the center frequency information.

Step 4 Open the selected CLI file for editing using any text processing application. Notice the power splitter and W0 values listed there. Either write them down or print them out.

Copy the "RFS" file to "C: \NaviniEMS\scriptsCopy the "RFS" file to "C: \NaviniEMS \scripts

Open "C:\NaviniEMS\Scripts \RFS", select the file with data measured at the frequency closest to the center frequency of the BTS

Open "C:\NaviniEMS\Scripts\RFS", select the file with data measured at the frequency closest to the center frequency of the BTS

Copy the "RFS" file to "C: \NaviniEMS\scriptsCopy the "RFS" file to "C: NaviniEMS\ scripts


Open "C:\CiscoEMS \Scripts\RFS", select the file with data measured at the frequency closest to the center frequency of the BTS

OL-16336-02


Step 5 Modify the line that starts with “bts” by changing the BTS ID for your BS. The default is “BTS 1”. For example, if the BTS ID for that BTS is 252, change the “1” to “252”. If the EMS ID was changed (default is 1), also modify the first line, which starts with “#EMSId” to match the new EMS ID. For example, if the EMD ID is 32, change the “1” to “32”.

Figure 7-36 Editing the RFS Script

Step 6 Save this file (keeping its ‘cli’ extension), and then close it.

Step 7 Start the EMS Config CLI application. To configure the BS with the BWX 8305 Basestation Antenna information, enter the following commands:

>enable <user name> (the “password:” prompt appears next) <password> >configure >script scripts/rfs/rfs_<serial number>_<7-digit frequency>.cli

Note For Unix Operating Systems, the CLI text is case sensitive and the slash marks should be backward slashes instead of forward slashes.

Step 8 View the power splitter values in EMS to verify that the CLI script ran as expected. The power splitter values may be found under Layer 1 / Show Configuration > Antenna Table. You will need to refresh the active screen to view the updated information (Figure 7-37).

This step may take a few moments. If the BTS fails to receive the configuration data from the EMS (the line will say “Pending” instead of “Done”), this step will timeout and the BTS will request the configuration data data again. If the BTS keeps trying and trying and still does not get the data from the EMS (each iteration may take 3 or 4 minutes), there is a communication problem between the BTS and the EMS. Check the Ethernet connections and/or the EMS IP address under SystemGeneral in the BTS Configuration record.

7.4.2.2 Check for Alarms

To check the EMS CAM for alarms, follow the instructions in Figure 7-41. All alarms must first be acknowledged, then cleared. Refer to the BWX EMS Alarm Resolution Reference Manual for look-up descriptions and resolutions for each alarm.

Figure 7-41 Check Alarms

Refer to Figure 7-42 for the Alarm Severity indicators.

1.Select BTS tab, then select one or more BTSs1. Select BTS tab, then select one or more BTSs

2. Click on theAlarm Icon to see the BTS Alarms


A few alarms will appear and will be automatically cleared during the BTS boot.Once an alarm is "cleared" and "acknowledged", it disappears.If an alarm is not automatically acknowledged you can acknowledge it manually to make it go away.


This is an alternative to viewing the outstanding BTS alarms by entering the ShowAlarmscommand at the "console" (terminal emulation) window

7.4.3 Provision the BWX 8305 BasestationWhen all of the basic BS configuration is completed, the BS needs to be provisioned. If the BS is “provisioned”, then any change to the record immediately affects the BS. If “unprovisioned”, you can change the record without affecting the BS. Certain actions (like “Calibrate”) require that the BS be “provisioned”.

The steps to provision the BS are shown in Figure 7-20 through Figure 7-27. Please refer to these figures as you read the remainder of this section.

Step 1 From the BTS tab, click on the BS which is to be provisioned.

Step 2 In the pull-down select Action > Provision to make that record active for the new BS.

Chapter 7 CommissioningCalibration

7.5 Calibration

7.5.1 What it Means to CalibratePerforming a calibration on the BS detects the phase differential between the antenna elements and matches the output power across all antenna elements in the BWX Basestation Antenna. On a new installation, the calibration procedure should be performed at least 3 times to verify consistency of the returned values. Ensure that the BS has been powered on, with the Power Amplifiers on, for at least 15 minutes to allow them to warm up and stabilize.

Caution Do not attempt to calibrate the Basestation while performing a software upgrade or downgrade. Calibrating during an upgrade or downgrade can interfere with the loading of files into system components and may produce faults or other problems.

7.5.2 Types of Calibration Assuming the BS has been powered up and left on for at least 15 minutes, and that all alarms have been cleared, you can now run a calibration. There are 2 types of calibration:

• Full Calibration

• Online Calibration

Typically, only the Full Calibration is done manually by the Service Provider. For the initial installation, the Full Calibration will be run at least 3 times.

Note Cisco recommends that a Full Calibration be performed on each BS, at least once every 4 weeks.

When a Full Calibration is invoked, the BS is out of service for about 2 minutes. After installation, commissioning, and acceptance testing, Cisco recommends that a Full Calibration be run every 2 weeks during off hours. During Full Calibration the Digital card pre-calibrates itself and the BS closes any ongoing sessions with Modems that are currently registered. The transmit gain in the IF section is adjusted for each of the 8 transmit paths individually so that the level of power delivered at the base of each antenna element is exactly the value specified by the Antenna Power parameter.

The receive gain is adjusted for each of the 8 receive paths individually so that when the level of power specified by the Rx Sensitivity parameter is received at the base of each antenna element, it will correspond to the maximum voltage that the card can handle. If the card is unable to adjust either the TX gain or the RX gain for a particular antenna element, both gain values are set to zero (0) and this antenna element is taken out of service.

Then, all paths are turned on using the gain settings just determined by the calibration, and the phase and amplitude changes introduced in each sub-carrier between the BS and the base of each antenna path are determined, both in the transmit and receive directions. This is done with power applied to all antenna paths and using the TX and RX gains in the card, as determined in the previous step, in order to achieve the power levels specified by the Antenna Power and Rx Sensitivity parameters.

Once the new phase change values are determined, they are compared with previous results kept in the BS’s memory. If there is a large discrepancy with the previous results, an alarm is generated and the BS uses the most likely correct set of values. Otherwise, the new results are sent to the EMS and kept in the BS’s memory for future comparisons.


OL-16336-02


When the BS is calibrated, the measured values are stored in the BS, erasing the previous results, and then reported to the EMS to be stored under Air Interface > Layer 1. The Digital card pre-calibration values are placed in the General tab. The TX and RX gain values are placed in the Antenna Table.

7.5.3 Calibration ProcedureBefore you can calibrate, ensure the following requirements are met:

• The BS must have been previously added and configured in the EMS database

• The BS must be powered up for at least 15 minutes, booted properly, stable (not resetting) and all alarms cleared before running the calibration

• Select the BS on the EMS CAM by clicking on the BS

• Right-click on the highlighted BS and select Action > Provision

Note The BS must be provisioned before you can calibrate. If the BS is not provisioned, refer to 7.4.3 Provision the BWX 8305 Basestation for the steps to perform the provisioning.

Step 1 Select Air Interface > Layer 1 > Layer 1 Tables.

Step 2 Click on Show Configuration.

Note Go through the first three tabs to verify that the proper values are entered in the Antenna Power, Receiver Sensitivity, RF & Cal Cable Loss, Power Splitter, and other fields.

Step 3 From a terminal emulation program type in the command, caldebugon and hit <Enter> (Figure 7-45).

Figure 7-45 Show Configuration

Step 5 Select Full Calibration and Calibrate and then click on Yes. Refer to Figure 7-46.

Figure 7-46 Full Calibration

Note If you forgot to provision the BS in the EMS database, you will see the error shown in Figure 7-47. Click on Ok and refer to 7.4.3 Provision the BWX 8305 Basestation.

Figure 7-47 Provision Error

When the calibration is complete, the Full Calibration window changes and displays the finish time and the result. Note that the result of “Succeeded” means that the calibration finished, not that the calibration results were successful (Figure 7-48).

Step 6 Click on Close to close the Full Calibration window

Click on the " Antenna Table" tabClick on "Calibrate"Select"Full Calibration" and click on "Calibrate"Click on "Yes"





OL-16336-02


Figure 7-48 Calibration Results

Step 7 Click on Show Configuration to see if the calibration is successful. In the EMS CAM highlight the BS and check the Antenna Table transmit and receive gain values (Figure 7-49).

Note A value of zero indicates that a proper value for the gain for that path (either in the TX or Rx direction) could not be found.

Figure 7-49 Check Antenna Table Values

Step 8 Check the calibration results for the Transmit and Receive Gain Values.


OL-16336-02


Note The BS system has a Transmit Gain value range of 1-64 and a Receive Gain value range of either 115-255 or 0-140. When evaluating calibration gain words, it is important to remember that the size of the value does not determine if a problem exists.

To determine if a problem exists, use the following information:

• At the BS console, look at the cal error message. The calibration should pass without any errors.

• Look at the Transmit Gain values. They should be relatively close to each other (values: 1 - 64).

• Find the median Transmit Gain value. The median is the value that falls in the middle of the lowest to highest values. Example: If you ordered the values 9, 8, 8, 7, 7, 6, 5, 4, 3, 3, 3, 2, 1, 1….the median would be 5 because 5 falls midway from the top or bottom of the ranked values.

• Compare all the other Transmit Gain values to the median value. All Transmit Gain values should be within a plus or minus range of 6 units from the median. Therefore, if the median is 50, values from 44 to 56 would be acceptable.

• Look at the Receive Gain values. (values: 115 – 255)

• Find the median Receive Gain value.

• Compare all the Receive Gain values to the median value. All Receive Gain values should be within a plus or minus range of 8 units from the median. Criteria: Transmit Gain Words +/- 6 from the median value Receive Gain Words +/- 8 from the median value

If this is a new installation (or a problem is found), repeat the calibration procedure (Steps 4-8). This will be the second of three calibrations you will perform. Click on the Configure button for this BS, and a new window appears (Figure 7-50). The main “Show” window still shows the results of the first calibration. The Configuration window shows the values corresponding to the second calibration.


OL-16336-02


Figure 7-50 Second Calibration (if needed)

Compare the values of both calibrations. The corresponding results should be within +/- 3 units. Close the Configuration window, and click on Show Configuration to move the second calibration values into the main window.

Next, perform a third calibration (Steps 4-8) and compare the results with the second calibration values. An example of successful calibration results is provided in Figure 7-51. An example of calibration results with errors is shown in Figure 7-52.

Chapter 7 CommissioningAdd, Configure, Modify and Delete Subscriber Stations (SSs) & Use Related Applications

7.6 Add, Configure, Modify and Delete Subscriber Stations (SSs) & Use Related Applications

References:

• BWX 110 Desktop Modem User Guide

• BWX 120 PCMCIA Modem User Guide



7.6.1 OverviewBefore going straight into the SS configuration in BWX EMS, some background understanding is required. First, this section discusses the different types of SS’s, and basic communications with a BS. Much of this information will become clearer when you get ready to conduct the commissioning tests – the Drive Study and Location (FTP) Test. The BWX Modem Diagnostics (NavDiag) tool and the BWX WiMAX Diagnostics (Beamforming Display) Tool are also covered in this section, since BWX Modem Diagnostics and BWX WiMAX Diagnostics are used to monitor SS operation and for troubleshooting purposes.

In order to continue commissioning and testing a newly installed, powered up, and calibrated BS, you will need to be able to add SS records to the database for use during the Commissioning tests - for example, records with max throughput for FTP tests and records with minimum throughput for test drives.

7.6.2 Types of SS’sThe first type of SS is the BWX 110 Desktop model. The BWX 110 provides an easy-to-read faceplate that instantly lets you know if the SS is searching for a BS, or is in stand-by mode (idling), or is already communicating with a BS, and, if it is, the signal strength and quality level (Figure 7-53). The BWX 110 Desktop Modem interfaces with a computer through an Ethernet cable.


OL-16336-02


Figure 7-53 BWX 110 Desktop Modem

The second type of SS is the BWX 210 Desktop Modem. The BWX 210 provides a Light-emitting Diode (LED), on the top back of the unit, which gives an indication of the modem’s operational status. When the light blinks, the BWX 210 Desktop Modem is trying to synchronize with a BS. When the light is constant, the BWX 210 Desktop Modem has acquired synchronization with a BS. If the light is flashing quickly, this means the BWX 210 Desktop Modem is transmitting data to the BS. The BWX 210 Desktop Modem interfaces with a computer through an Ethernet cable.

Figure 7-54 BWX 210 Desktop Modem

Another type of SS is the BWX 120 PCMCIA Modem (Figure 7-55). A BWX 120 works with laptop computers by sliding into the PCMCIA slot on the laptop. There are no cables. Please note that a PCMCIA Card cannot be used for commissioning testing of the BS.

The two arrows are displayed whenthe SS is transmitting/receiving butnot when it is “idling”.

Once the Global Config menu parameters are configured, push the EMS data to the BWG. Refer to Figure 7-57.

Figure 7-57 Push EMS Data to BWG

The SS can now be added to the AAA server. For detailed steps, refer to the Configuring WiMAX Subscriber Stations Using Cisco Access Registrar (CAR) document.

EMS supports two versions of SS:

• Cisco16e (SS operating in WiMAX)

• WiMAX (both third-party and Cisco SSs)

For the steps to add, configure, modify and delete SS’s, refer to the BWX Mobile WiMAX Configuration Guide.

OL-16336-02


7.6.4.1 Description

BWX Modem Diagnostics tool is a software application that runs on the end-user’s computer. It is used to collect, view, and graph information about the SS equipment, software level, performance, and other statistics. An SS can be installed and operational, however, without the user ever installing the BWX Modem Diagnostics tool. Though this software application is primarily used by the end-user when the Service Provider’s support personnel are helping the user to troubleshoot an issue, it is also used by installers when commissioning the Basestation. The BWX Modem Diagnostics tool provides a logging mechanism to be used in the Drive Study and Location (FTP) Test.

7.6.4.2 Installation Procedure

The BWX Modem Diagnostics tool works on three Operating Systems: Windows®, Linux®, and Apple®. When first loaded on a computer the application displays in a novice mode. The novice mode provides limited information about the SS and its communications. The novice mode is appropriate for end-users. However, an experienced technician or field support engineer can invoke more detailed data and functionality through the advanced mode ( Figure 7-58). To invoke the advanced mode, you select Control+Shift+F10.

The BWX Modem Diagnostics tool installation procedure is captured in the specific SS user guides. Once the application is installed on the computer from the Installation CD that comes with the SS, you simply double-click on the icon (Figure 7-59).

Figure 7-59 Install BWX Modem Diagnostics Tool

One of the nice things about the BWX Modem Diagnostics tool is that the Service Provider can invoke it from the EMS. This allows the Service Provider to monitor and troubleshoot end-user issues remotely. For purposes of commissioning the BS, however, you will be using the BWX Modem Diagnostics tool installed “locally” on a laptop computer.

7.6.4.3 Location (FTP) Test Logging

A Location, or FTP, Test is part of the commissioning and acceptance testing of a BS. This test helps to verify throughput operates at various locations.

To create a Location (FTP) Test log file, go to the BWX Modem Diagnostics tool advanced mode and select “Session” > “Logging” > “Start Location Test Log”. Enter the company name and BTS ID, then click “OK” (see figure below). This starts the data collection. The file name is generated based on the company name and BTS ID plus the Modem EID. The location of the file is predetermined (C:\Program Files\NavDiag\data\ log).

7.6.5 BWX WiMAX Diagnostic Tool OperationReference: BWX WiMAX Diagnostic Tools Guide

7.6.5.1 Description

One of the diagnostic tools supplied when you load the EMS Client software is the BWX WiMAX Diagnostic Tool. Sometimes simply referred to as ‘beamforming’, this application is used during commissioning and acceptance testing, as well as over the life of the product. The tool provides numerous types of data that give performance information used during troubleshooting.

You do not have to do anything to configure BWX WiMAX Diagnostic Tool. We are discussing how to use the BWX WiMAX Diagnostic Tool application at this point because it is used to monitor the communications between an individual SS and the BS, when the BS tab is selected within the tool. This understanding will become important later as you start the commissioning tests. You will first need to have a test SS already added and configured in EMS in order to use the BWX WiMAX Diagnostic Tool.

To start the BWX WiMAX Diagnostic Tool, double-click on the icon that appears on the desktop where you installed the EMS Client applications (Figure 7-60). The tool will prompt you for a user name and password, which are the same as those used for the EMS CAM:

• Default User Name: ems

• Default Password: emsdiag7

Note that you will enter the SS’s EID, and you will also have to select the type of antenna to be linear (panel).

1. Select: "Session→Logging→Start Drive test Log"1. Select: "Session→Logging→Start Drive test Log"

2. Enter "Company Name" and "BTS Id" 2. Enter "Company Name" and "BTS Id"

Chapter 7 CommissioningBWX 8303 Basestation Timing System Verification

Figure 7-61 Beamforming Data

7.7 BWX 8303 Basestation Timing System VerificationCommissioning the BS requires you to first verify that the BXW 8303 Basestation Timing System antenna is working properly. The BXW 8303 Basestation Timing System provides the timing and synchronization of transmission signals. Be sure to check all regulatory information for using a GPS system prior to installing.

To make sure the BXW 8303 Basestation Timing System antenna is working properly, use a handheld GPS unit to get a position reading at the Basestation location. Wait until the BS has had time to get a GPS position fix.

Next, using the EMS CAM, go to the BTS tab and select the BS. Open the General > GPS branch, and click on Show Configuration. Read the GPS latitude and longitude on the BS record, and compare them to the readings of the handheld GPS unit. If the readings are different, the GPS Verification test fails. Use the troubleshooting information that came with the BXW 8303 Basestation Timing System, to set the BS’s latitude & longitude, to resolve the problem.

If, up to this point, you have been using a “test” EMS Server, you should now install the customer’s EMS Server and configure it. Verify that the latency between the EMS and BS is < 10 ms. Complete the minimal configuration datafill, and run the RFS Configuration data from the floppy disk. Run the Full Calibration until results are successful 3 times.


OL-16336-02

Chapter 7 CommissioningLocation (FTP) Test

7.10 Location (FTP) Test

7.10.1 PurposeThis test got its name because the technician or engineer drives to various locations in the cell area and transfers data files to see what kind of uplink and downlink throughput the system provides. You will perform this procedure more than one time in the overall process of completing the system deployment. At this time you are still commissioning the BS into operation; later, you will perform this test to verify its operation as part of Acceptance Testing. You want to be certain when you turn the system over to the Service Provider that its operation is stable.

7.10.2 Setup & ProcedureTo perform this test you must have direct access to an FTP server that is not behind a Network Address Translation (NAT) server. You will also need an FTP client application running on the laptop connected to a Modem and used during the test to generate traffic by initiating file transfers (Figure 7-66).

Figure 7-66 Setup

Several types of data are collected during this test. First, you will use the BWX Modem Diagnostics Tool to start and stop Location Test logging. You will manually keep track of two parameters in the BWX Modem Diagnostics Tool by recording the information into a spreadsheet. Primarily, you are looking at the CINR and RSSI averages for quick comparison against predefined acceptability criteria. The FTP program provides statistics on the data rates, but the data is simultaneously captured by the BWX WiMAX Diagnostics tool.

OL-16336-02

Chapter 7 CommissioningLocation (FTP) Test

The first site should be a clear line of sight (LOS) about 2 km away from the BS. You will choose a premium site, where you expect to get the best throughput from the system. The data from this location will constitute your baseline for future comparisons. After performing the data captures at this site, you will continue moving to other LOS and non line of sight (NLOS) locations based on the preliminary RF propagation model generated for this site.

If the site has a panel BWX Basestation Antenna, select 4 additional locations. For NLOS sites, test both outside and inside a building or other structure so that penetration loss can be determined. You will record all data in the Closeout Tool (Figure 7-67). This information will be sent to Cisco TAC for evaluation as part of the closeout documentation.

Figure 7-67 Closeout Tool

7.10.3 Acceptance CriteriaThe CINR seen in the BWX Modem Diagnostics tool should be fairly consistent. The minimum values to achieve the desired throughput are:

• DQPSK (QAM4):At least 5 dB

• 16QAM (QAM16):At least 11 dB

The uplink and downlink Packet Error Rates (PER) should not exceed 1%, although this will vary according to interference levels. The SS Transmit Power should be well below its maximum (typically 25 dBm), and the BS Transmit Power should be at the value set in the EMS.


OL-16336-02

Chapter 7 CommissioningDrive Study Test

7.11 Drive Study Test

7.11.1 PurposeWhen an Service Provider is planning a cell site, either the Service Provider or Cisco predicts the coverage area and plots the anticipated coverage on a map. You want to be sure that the BS can be seen by the SS. The output of an RF coverage analysis before the site is deployed is based on geodata for that region, as well as information that is specific to the BWX Mobile WiMAX system. The RF Engineer can plot the known data using a software program, such as PlanetEV®, which produces a plot graph (Figure 7-68) that uses color coding to predict coverage quality based on signal strength (dB). The predictive coverage analysis is used to plan the Drive Study route (Figure 7-69).

Figure 7-68 Coverage Prediction Map

You are going to be driving at approximately 33.5 mph (54 kph). This speed will provide data collection points every 50 ft (15 m) apart. Going any faster than 35 mph will result in an increased separation between the points. To avoid overloading the cigarette lighter for connections, try to use a car that has two cigarette lighters, one for the GPS receiver and one for the laptop.

After starting the BWX Modem Diagnostics tool program to log driving data, you will need to monitor the “DL Burst RSSI Mean AMC” value in the Statistics screen of the BWX Modem Diagnostics tool. After starting the laptop, power on the GPS receiver. Make sure that you can see the GPS coordinates changing in the window as you drive. After data is collected, you will input it in the Closeout Tool (Figure 7-72). This data may be sent, along with other data collected, to Cisco, as well as provided to the Service Provider.

Figure 7-72 Closeout Tool

7.11.3 Pre-process the Drive Study DataBefore sending the data collected during the Drive Study to Cisco for the Propagation Model Tuning, the following steps should be performed to “pre-process” the data:

• Sort the rows by BTS id and delete all the points collected from a BS other than the one being studied.

• Sort the rows by Latitude and Longitude and delete all the points without GPS coordinates.

• Sort the rows by RSSI and delete all the points with the RSSI above –30dBm and below –110 dBm.

• Delete all the columns except Latitude, Longitude, and RSSI.

• If needed, reorder these columns so that the first one is Latitude, the second is Longitude, and the third is RSSI.

• Delete the first row containing the headers.

7.12 Export BWX EMS DatabaseReference: BWX Mobile WiMAX Configuration Guide

7.12.1 Create Text FilesWith commissioning almost complete, you will need to export the EMS database, including the global parameters, the EMS, and the BS data. When you export the data, it saves the datafill information in a text file format. The text information can be used if a re-entry of data is ever required, and it can be used during troubleshooting later on. It is a good idea to back up and export the data periodically and whenever any significant configuration data is changed. As a general guideline, Cisco recommends a backup and export once per week.

Chapter 7 CommissioningBack Up BWX EMS Database

7.13 Back Up BWX EMS DatabaseReference: BWX EMS Administration Guide

At this point you are almost finished with this site. You may have had to adjust some parameters, troubleshoot, recalibrate, or rerun tests. Once you are satisfied that the BS is operating properly, you need to back up the EMS database. For this task you will use the EMS Admin CLI application that was part of the EMS Server installation.

The Admin CLI initially opens up in the default mode, which is called the User Mode (Figure 7-76). A mode is an environment in which a group of related commands is valid. The second mode is called the Admin Mode. All commands except “?” are mode-specific. At any point in the Admin CLI you can type in “?” to view a list of commands that are valid for that mode.

Figure 7-76 Admin CLI

You will be in the User Mode to perform a backup of the EMS database. When backing up the database, you must specify the directory to which you want the data copied (Figure 7-77). You should have the directory set up before initiating the backup using the Admin CLI.

P P E N D I X B Cisco Recommended Tools
This document provides a list of required tools for installing or troubleshooting a Cisco BWX 8305 Basestation (BS) (Table B-1).

Note As with any hardware or any troubleshooting, you will need basic tools like screwdrivers, pliers, voltmeter, etc.

Only a Cisco qualified specialist installer should install the BS and BWX Basestation Antenna. The BWX Basestation Antenna can be installed by non-certified personnel on any tower as long as a qualified installer/supervisor is available to verify and complete the BS installation and commissioning procedures.

Please note that if you are installing a 2.4 Ghz BS, this frequency is usually an unlicensed band system. Because many vendors can operate in the unlicensed band and change frequencies at will, there may be interference from other systems also running in the 2.4 GHz spectrum. You must measure the interference of the area before and during the installation of the system. The reason for looking at the interference beforehand is to see if the level is low enough to operate the BWX Mobile WiMAX system successfully.

P P E N D I X E RF Center Frequency & Interference Analysis Guidelines
Reference: RF Center Frequency and Interference Analysis

These guidelines are intended for an experienced and Cisco qualified specialist Field Engineer to gather data for RF Engineering purposes. The procedures that are described are performed in order to make a determination of Basestation center frequency and possible interference points in both licensed and unlicensed spectrum. Please refer to all regulatory information for your region prior to performing these procedures.

Before You Start

OverviewAn RF interference analysis is usually called for under two conditions. One is when it is used for evaluating a candidate BWX 8305 Basestation (BS) site prior to deployment of equipment. We refer to the interference testing under these circumstances as a Pre-installation Test. The second is the Post-installation Test, when data is collected to determine (a) if there is any interference in the area at all; or (b) the source, or cause, of known interference in the area of the installed and operational site. As is obvious from the name of this test, it occurs after the Basestation has been deployed and turned up.

The instructions in this document assume the Field Engineer is at the BS site where the testing will take place. The data the Field Engineer gathers using the Interference Sweep procedure in this document will be evaluated and used in the calibration of the Basestation. In unlicensed systems, this will help determine the selection of the center frequency. In licensed systems, the data will help verify and plan for noise in the area.

To get the most benefit from this procedure, we suggest you follow these high-level steps:

Step 1: Read the entire procedure.

Step 2: Choose the correct Test configuration setup, per this procedure.

Step 3: Perform the Interference Sweep procedure.

E-1tation Installation and Commissioning Guide

Appendix E RF Center Frequency & Interference Analysis GuidelinesSpectrum Analyzer Settings

Step 4: Send the results to Cisco.

Required EquipmentYou will need the equipment shown in Table E-1 to complete the interference testing.

Table E-1 Required Equipment

Spectrum Analyzer SettingsThere are two types of interference tests conducted under either the Pre-installation or Post-installation situation: Frequency Domain test and Time Domain test. The following section explains some specific settings on the Spectrum analyzer, and what effects they will have on these tests.

Frequency Domain TestThe Frequency Domain test is a measurement of the amplitude of an incoming signal across a given frequency span. Setup for the Spectrum Analyzer:

• Frequency = the channel to be tested (refer to frequency charts later in procedure)

• Bandwidth (BW) = 100 KHz or lower

• Reference Level = –50 dBm

• Attenuation = 0 dB

Equipment Comments

HP4404B, FSH3, or FSH6 Spectrum Analyzer (or equivalent)

NOTE 1: If checking for 3.4/3.5 GHz spectrum, make sure the Spectrum Analyzer reads up to 4 GHz.

NOTE 2: An equivalent analyzer must have the following functions: Screen Save abilities, Max-hold function, Peak search, and ability to operate in the required frequency range

• Preamp, if available = on

• Span = determined by the start and stop frequencies

For the Frequency Domain test, the two parameters most frequently configured incorrectly are Reference Level and Bandwidth. To help the user determine the best settings, this section gives a short description as to what changes will be seen on the display if the parameter is changed.

Reference Level

This parameter sets the level of the top line of the Spectrum analyzer display (Figure E-1). Figure E-1 shows a display with the reference level set to –50 dB and the noise floor at –104 dB. The Blue line is a display line showing a level of –103.9 dB.

As you can see, the top-level line displays –50dB. On most Spectrum Analyzers the RF noise floor is coupled with the Reference Level line. A Spectrum Analyzer will try and display the noise floor on screen. If the reference level is set at a level that is too high for the Spectrum Analyzer to display the noise floor, it will automatically change the displayed level for the noise floor (Figure E-2).

Figure E-1 -50 Reference Level l


OL-16336-02


Figure E-2 -10 Reference Level

Bandwidth

Figure E-2 shows a reference level setting that was manually raised in the Spectrum Analyzer to –10. The blue line is the display line that was set with the original noise floor at the –50 reference level. When the reference level was raised from –50 to –10 the displayed noise floor also raised approximately 25 dB By setting the reference level to a lower value, the Spectrum Analyzer is able to display a noise floor that is closer to the actual digital noise floor of the equipment.

Figures E-3 and E-4 show the reason the reference level is important for capturing data for interference measurements. In Figure E-3, the reference was set at –50 dB level. A –65 dB signal was injected into the Spectrum Analyzer. In Figure E-4 the same –65 dB signal level was injected into the Spectrum Analyzer, but the reference level was changed from –50 dB to –10 dB.

Figure E- 4 still shows the –65 dB signal but only at 18 above the noise floor; whereas Figure E-3 shows the –65 dB signal at 40 dB above the noise floor. While measuring interference, if the reference level were set to –10 dB the Spectrum Analyzer would not display any signal levels below the displayed noise floor level, effectively masking any interference in that area.

OL-16336-02


The bandwidth parameter is used for the measurement and display of the signal level across a given range or span of frequencies. Within a given bandwidth there are 2 settings — one is Resolution bandwidth, and the other is Video bandwidth. To discuss bandwidth, an understanding of the Spectrum Analyzer display is needed. The display is broken out into frequencies and signal strength levels. Frequencies are displayed left to right, which is called the Span. The signal level is displayed from top to bottom and is shown with a signal strength level on the left side of the display.

Bandwidth in the Frequency Domain test is tied to the span function. Resolution bandwidth is the measurement steps or slices that the Spectrum Analyzer uses while sweeping across the span of frequencies. The Video bandwidth is the steps that the Spectrum Analyzer displays to the screen as it sweeps across the span of frequencies.

Two different bandwidths are used in the following examples. One is 10 KHz in a 5 MHz span (Figure E-5), and the second is 100 KHz in a 5 MHz span (Figure D6). With the 10 KHz bandwidth, the Spectrum Analyzer will make 500 steps to sweep the 5 MHz span, whereas on the 100 KHz bandwidth only 50 steps are made.

With a wider bandwidth (100 KHz) the receiver front-end of the Spectrum Analyzer is opened wider, allowing for more noise to be input. With the smaller bandwidth (10 KHz) the Spectrum Analyzer receiver is narrower and less susceptible to outside noise, thus giving a more accurate measurement. The drawback to a smaller bandwidth is the sweep time for the Spectrum Analyzer to step across the span. The sweep time increases, affecting the amount of time to perform the tests.

Figures E-5 and E-6 show the effect on the noise floor by increasing the bandwidth from 10 KHz up to 100 KHz. The setup in Figure E-5 is a 10 KHz resolution and video bandwidth, and a span of 5 MHz. In Figure E-6 the bandwidth was increased from 10 KHz to 100 KHz. By raising the bandwidth in Figure E-6, more noise was seen by the Spectrum Analyzer, in effect raising the noise floor and hiding over 10 dB of signal from view. When measuring for interference, this configuration can result in measurement error, giving the view that the interference is not as bad as it truly is.


OL-16336-02


Figure E-5 10KHz Bandwidth Setting

Figure E-6 100KHz Bandwidth Setting


OL-16336-02


Time Domain TestThe Time Domain test (Figure D7) is a measurement of the duration of an incoming signal across a given bandwidth. The duration of an incoming signal affects the number of packet errors that are generated over a given period of time. The longer the duration of the signal the more packet errors are generated. The number of packet errors will directly affect the data throughput rates of the system.

Setups for the Spectrum Analyzer are as follows:

• Frequency = center frequency to be tested

• Span = 0 Hz

• Video Bandwidth = 1 MHz

• Resolution Bandwidth = 1 MHz or 5 MHz

• Sweep Time = 40 ms and 400 ms

• Preamp if available = on

• Attenuation = 0 dB

• Reference Level = -40 dB

The following is a description of the parameters of the Spectrum Analyzer during the Time Domain test versus the Frequency Domain test, and what effects they will have if they are changed for the testing.

Span

The span function in the Frequency Domain test determines the start and stop range that the Spectrum Analyzer looks at for a given sweep time. By setting the Span to 0 Hz for the Time Domain test the Spectrum Analyzer looks at one specific frequency for a given amount of time.

Resolution Bandwidth

The resolution bandwidth parameter for the Time Domain test acts similarly to the span function in the Frequency Domain test. The bandwidth parameter opens up the receiver of the Spectrum Analyzer to look at all signals across that bandwidth for the given sweep time. The smaller the bandwidth, the more accurate the readings displayed.

This parameter also determines the frequencies that are to be tested for a given range. The BS uses a 5 MHz channel. If the Spectrum Analyzer can be programmed with a bandwidth of 5 MHz, then the center frequency to be tested is every 5 MHz. Some analyzers are only able to be programmed to 1 MHz, resulting in a center frequency test step of 1 MHz. This results in more frequencies to be tested, but a more accurate indication of where the interference is located in the spectrum.


OL-16336-02


Frequency examples:

5 MHz Resolution Bandwidth 1 MHz Resolution Bandwidth

2.4025 GHz 2.4GHz

2.4075 GHz 2.401GHz

2.4125 GHz 2.402GHz

Sweep Time

The sweep time parameter is the amount of time that it takes the analyzer to scan the set bandwidth. One transmit and receive frame on the Cisco system is 10 ms, so a sweep time of 40 ms shows 4 frames, and 400 ms shows 40 frames.

OL-16336-02


Test ConfigurationsThere are two configuration scenarios used for interference testing:

• Pre-installation Testing Configuration

• Post-installation Testing Configuration

Pre-installation Testing covers the initial equipment configurations when testing for interference at a site in order to determine whether or not the site is a good candidate for placing the BS. It describes the interference measurements prior to the installation of any BS equipment. The Post installation Testing section covers the measurements using the BWX Basestation Antenna after it has been installed on the radio tower or building. Use whichever configuration setting is appropriate to the type of data you are trying to collect, prior to performing the Interference Sweep procedure.

Pre-installation Test

Following is the setup of the interference test equipment prior to the installation of the BS equipment. This test is used to help determine if the site that has been selected is usable for the Cisco equipment, and what possible frequencies can be used after the installation.

Required Equipment

• Spectrum Analyzer (4404 or R&S FSH)

• Testing antenna

• RF cable

• LNA as required

Setup

Refer to Figure E-8 for the setup. The Test antenna on the tower is at the proposed installation elevation for the BWX Basestation Antenna. The RF cable will run from the Test antenna to the Low Noise Amplifier (LNA) or Spectrum Analyzer. The LNA may be required in order to add gain to the system to compensate for any losses that are added to the test by the RF cable or Spectrum Analyzer. The typical loss for a Spectrum Analyzer is around 30 dB. The RF cable losses will vary depending on the size and type of cable and on the length of the cable. In the example below, the total system loss would be 39 dB.

Example:

- Antenna Gain: 0 dB

- Cable Loss: 9 dB

- Loss in Spectrum Analyzer: 30 dB


OL-16336-02


In the example above, there is 39 dB of loss. In order for the interference measurements to give an accurate indication of the environmental noise, an additional gain of over 39 dBi would need to be injected into the test. The best location for the optional LNA would be at the top of the tower prior to the main run of RF cable. In this location the noise will be amplified prior to the loss through the RF cable. If the optional LNA is only installed at the lower end of the tower, the noise is reduced by the loss in the cable and would lose 9 dB of resolution.

Procedure

The setup shown in Figure E-8 and the information below are for the initial (pre-installation) configuration. It gives you a starting point for this procedure. During the later steps, the configuration will change. Configure the test equipment and antenna as depicted in Figure E-8.

Step 1. Program the initial Spectrum Analyzer settings, per the following:

A. Resolution Bandwidth = 30 KHz

B. Video Bandwidth = 30 KHz

C. Attenuation = 0 db

D. Ref Level = -50 db

E. Sweep Time = auto

F. Detector Mode = positive peak

G. Frequency = determined by which step you are on in the procedure

Step 2. Set the frequency sweep range, as follows. This depends on the frequency you are investigating.

A. Unlicensed 2.4 GHz = sweep for range 2.390 GHz to 2.5 GHz

A. Licensed 2.6 GHz = sweep for range 2.596 GHz to 2.644 GHz

B. Other Licensed Frequencies (i.e., 2.3, 2.5, 3.4, 3.5 GHz) = sweep the center frequency plus 6 MHz to check for adjacent channels

Proceed to the “Interference Sweep Procedure” section of this document.

Post-installation Test

The post-installation test is used to help verify the operational frequency that the BS will use. If the system performance has degraded, this test can determine if there is another carrier causing problems in the RF environment.

Required Equipment

• Spectrum Analyzer (4404 or R&S FSH)

• BWX Basestation antenna

• RF cable connected to antenna

• RFS Test Box

• External LNA, as required


OL-16336-02


Set-up

Refer to Figure E-9 for the setup. In this setup, the BWX Basestation antenna is installed on the tower or building. The RF main feeder cable connects to the optional LNA or to the Spectrum Analyzer. The LNA may be required to add gain to the system to compensate for any losses that are added to the test by the RF cable or Spectrum Analyzer. The typical loss for a Spectrum Analyzer is around 30 dB. The RF cable losses will vary depending on the size and type of cable and on the length of the cable. In this example, the total system loss would be 19 dB.

Example:

- Antenna Gain: 20 dBi

- Cable Loss: 9 dB

- Loss in Spectrum Analyzer: 30 dB

Using this example, with a loss of 19 dB, in order for the interference measurements to give an accurate indication of the environmental noise, an additional gain of over 19 dBi needs to be injected into the test.

NOTE: When you are calculating whether you need to add additional LNA, you need to have the following information.

• Legacy LNA ~ 20 gain

• 2.4 TTA LNA ~20 gain

• 3.4 and 3.5 TTA LNA ~45 gain

• Most Spectrum Analyzers have an internal noise figure of –30

Procedure

The setup shown in Figure E-10 and the information below are for the post-installation

test configuration.

Step 1. Configure the test equipment as depicted in Figure E-10.

Step 2. Program the initial Spectrum Analyzer settings, per the following.

A. Resolution Bandwidth = 30 KHz


OL-16336-02


B. Video Bandwidth = 30 KHz

C. Attenuation = 0 db

D. Ref Level = -50 db

E. Sweep Time = auto

F. Detector Mode = positive peak

G. Frequency = determined by which step you are on in the procedure

Step 3. Set the frequency sweep range, as follows. This depends on the frequency you are investigating:

A. Unlicensed 2.4 GHz = sweep for range 2.390 GHz to 2.5 GHz

B. Licensed 2.6 GHz = sweep for range 2.596 GHz to 2.644 GHz

C. Other Licensed Frequencies (i.e., 2.3, 2.5, 3.4, 3.5 GHz) = sweep the center frequency

plus 6 MHz to check for adjacent channels

D. RFS Test Box for any system needs to be set in Rx mode only

Interference Sweep ProcedureThis procedure guides you through the steps to capture the data required for the interference study. The number of steps will change with the type of antenna you are using and the frequency band you are investigating.

For the Panel antenna, the number of passes through the procedure is determined by the beamwidth of the antenna. When using a Panel antenna to pick up the interference, try to change the angle or downtilt to face a potential interference source, such as a tower or a more populated area.

A Panel antenna is used to determine where a source of interference is coming from. The beamwidth of the Panel antenna determines the number of directions that you need to sweep. For example, if the beamwidth of the Panel antenna is 120 degrees, then 3 passes of the procedure are necessary in order to cover 360 degrees. Whereas, an antenna with a 30 degree beamwidth requires 12 sets of sweeps to cover the same 360 degree area.

The smaller beamwidth requires more sweeps but gives you greater accuracy in determining the source of the interfering signal. On each pass, the Panel antenna is moved per the beamwidth. Refer to Figure

E-11.

Figure E-11 Panel Sweep


OL-16336-02


Try to determine the polarization of the interfering signals during each sweep. To do this, flip the antenna 90 degrees. All captured measurements are with the antenna in the vertical polarization position.

The frequency band to be investigated is determined by the range of the BS that is purchased by a customer. For example, the 2.6 GHz MMDS band is a licensed band, and the customer purchasing the equipment will have a license for a given 6 MHz channel. The 2.4 GHz band is an unlicensed frequency range that is open for many applications. The objective for the 2.4GHz sweeps is to find a 5MHz range that is the clearest of any interference.

The sweeps for licensed spectrum are performed to verify that there is not another carrier infringing on the given licensed channel. If you are performing the sweeps for a licensed channel, it will greatly reduce the number of steps that you will need to perform. For a licensed spectrum system you only need to look at 3 channels for the spectrum. You will sweep the licensed channel, as well as the channels above and below the licensed band.

For example:

If you have an E3 license (2.620 GHz – 2.626 GHz), you will sweep E3 plus F2 (2.614 GHz– 2.620 GHz) and F3 (2.626 GHz – 2.632 GHz).

You will only need the Max-hold portion of the procedure for licensed spectrum systems.

Frequency Domain (Max-hold) Test ProcedureThe Max-hold procedure is to be used for both unlicensed and licensed systems.

Step 1. Check the direction of the antenna with a compass. Record the results.

Step 2. Set the “Start Frequency” to the minimum sweep range for the spectrum you are testing.

Step 3. Set the “Stop Frequency” to the maximum sweep range for the spectrum you are testing.

Step 4. Replace the antenna with a terminator to get a noise floor level. Save a screen capture.

Step 5. Turn on the “Max-hold” feature and acquire the signal for two minutes, and again for 30 seconds. Save a screen capture in Tiff or Gif format.

Step 6. Run “Single Sweep” 2 times, saving the screen captures for both sweeps. This gives a reference for the worst case that is shown with the “Max-hold” in Step 5. You can save time on this step if the Spectrum Analyzer is equipped with a Dual Trace option. Turn on Trace 2 to constant sweep and Trace 1 on Max-hold. After the Max-hold has acquired a signal for two minutes, press the single sweep. Save the screen capture. Refer to Figure E-12, Max-hold Screen Capture.

Analyzing the Test Results

Once the procedures are completed, use the following guidelines to analyze the results. First, you will look at the Frequency Domain data, and, for unlicensed systems, also the Time Domain data. If you need help, please contact the Cisco TAC (1-800-553-2447).

Frequency Domain Interference Sweeps AnalysisThe Frequency Domain Interference Sweep has two kinds of measurements, Max-hold and Single Sweep. First, we have to determine the theoretical noise floor. We will use the theoretical noise floor to interpret the Max-hold sweeps data.


OL-16336-02


Calculating the Theoretical Noise Floor

All analysis of interference is done from the theoretical noise floor. This is the best-case noise floor in a perfectly clean environment. The following algorithm is used to determine the noise floor.

Theoretical noise floor (NF) = Thermal NF @ 1 Hz and 20° C + sub-carrier channel energy + Cisco BWX Mobile WiMAX system noise figure

Thermal NF @ 1 Hz and 20° C = -174 Sub-carrier channel energy = 10log(500 KHz) = +57 dB Cisco BWX Mobile WiMAX system noise figure = +5 dB

Resulting theoretical noise floor -174+57+5 = -112 dBm

If the setting on the Spectrum Analyzer was 30 KHz and not 500 KHz, there would be a 12 dB difference in the setting, which means the thermal noise floor for 30 KHz @ 20° C would be –124 dBm.

Analyzing the Max-hold Sweeps

The BWX Basestation is able to correct for a specified level of interference. This level will vary depending on the type of system or software load that is running on the BWX Basestation.

• Licensed systems (2.3, 2.5, 2.6, 3.5 GHz) +5 dB over theoretical noise floor

• Unlicensed systems (2.4 GHz) +15 dB over theoretical noise floor

This means that any signals on the capture for the Max-hold sweeps above –107 dBm for licensed bands (0 through –106.9) or –97 for unlicensed bands (0 through –96.9) are not acceptable for spectrum usage This is summarized below:

• -112 + 5 dB = -107 dB for licensed systems

• -112 + 15 dB = -97 dB for unlicensed systems

NOTE: If using 30 KHz for the bandwidth setting on the Spectrum Analyzer, the levels will need to be increased by 12 dB: -119 dB for licensed systems and –109 dB for unlicensed systems.

Evaluating the Signal with Additional Gain

So far all of the values that have been discussed – noise floor, signal levels, etc. – have been with no gains or losses in the test set-up. This will not be the case in the real world. In the data capture, additional gain was added to the set-up to overcome any losses that are in the system due to cable or connection losses. When analyzing the interference signals, this additional gain must be removed to determine the actual interference signal level.


OL-16336-02


For example:

Set-up 2.4 GHz Omni system -8 dB of cable loss +18 dB gain in Spectrum Analyzer pre-amp Spectrum Analyzer was set for 30 KHz bandwidth

Results Theoretical noise floor = -124 dB Acceptable interference signal level for 2.4 GHz = theoretical NF + unlicensed system level: -109 dB = -124 dB + 15 dB

Total Gain on the Set-up +30 dB = +20 dB on Omni + -8 dB of cable + 18 dB on pre-amp

With the above example the incoming signals will be amplified by +30 dB. This additional 30 dB will need to be taken into account when evaluating any interference. This is done by reducing all levels by the 30 dB to compare them to the –109 dB acceptable level.

Incoming signal level – 30 dB = actual signal level

For unlicensed 2.4 GHz bands, if all the 2.4 GHz bands’ Max-hold sweeps are 15 dB higher than the noise floor, the Engineer should investigate the Time Domain sweep results.

Time Domain Interference Sweeps AnalysisThe Time Domain sweeps capture how the interference sources behave, if the interference is constantly there or operating in a hopping method. Time Domain sweeps are typically used for the unlicensed 2.4 GHz systems’ interference measurements.

Calculating the Theoretical Noise Floor

All analysis of interference is done from the theoretical noise floor. This is the best-case noise floor in a perfectly clean environment. The following algorithm is used to determine the noise floor.

Theoretical noise floor (NF) = thermal NF @ 1 Hz and 20° C + sub-carrier channel energy + Cisco BWX Mobile WiMAX system noise figure

Thermal NF @ 1 Hz and 20° C = -174 Sub-carrier channel energy = 10log(500 KHz) = +57 dB Cisco BWX Mobile WiMAX system noise figure = +5 dB

Resulting theoretical noise floor -174+57+5 = -112 dBm


OL-16336-02


If the setting on the spectrum analyzer was 30 KHz and not 500 KHz, there would be a 12 dB difference in the setting, which means the thermal noise floor for 30 KHz @ 20° C would be –124 dBm. If the setting on the spectrum analyzer is set for 1 MHz and not 500 KHz, there is a 3 dB difference in the noise floor, meaning that the theoretical noise for 1 MHz @ 20° C is –109 dBm.

Analyze the Time Domain Sweeps

The BS is able to compensate for 320 μs per each 10 ms frame. This 320 μs timeframe only comes into play when the signal level of the interferer is above the levels determined in the Max-hold section. The 320 μs duration is an additive duration throughout the 10 ms timeframe. If all of the interference signals above the determined signal level add up to be longer than 320 μs, then that frame is unusable.

P P E N D I X I Guidelines for Painting a Cisco Antenna
DisclaimerAlthough Cisco does not recommend the application of paint or primer to a Cisco BWX Basestation Antenna, whether for aesthetics or camouflage purposes. The reasons why Cisco does not recommend the application of paint or primer to a Cisco antenna are as follows:

• Adding material through which the antenna beam must penetrate may hinder the overall performance and gain of the antenna.

• An uneven application or accumulation of material, paint, or other material will cause varied and unpredictable antenna performance.

• Dark colors may raise the thermal load of the internal electronics above design limits. Paint applied over a heat sink impedes thermal performance of the heat sink.

If the Service Provider must apply paint, primer, or other material, the following are guidelines for selecting and correcting the application of paint. Though this document refers to specific products, Cisco does not endorse any paint manufacturer or manufacturer of paint application equipment.

Appendix I Guidelines for Painting a Cisco AntennaGuidelines for Painting a Cisco BWX Basestation Antenna

Guidelines for Painting a Cisco BWX Basestation Antenna

BWX Basestation Antenna MaterialsPaint and primer should be suitable for application to these materials:

• One-piece Sector Panel antenna are Kydex™.

• BWX Basestation Antenna with 8 individual antenna elements are PVC or PC/ABS

Paint/Primer TypesWhere the RF degradation of a particular paint is uncertain, a painted coupon should be tested using industry-standard methods for characterizing antennas at an accredited antenna range using the Cisco antenna. Post-application of the paint should show no discernible difference in antenna pattern, gain, or any other radiation characteristics.

The selected paint shall be non-hygroscopic (shall not have a tendency to absorb water). The paint shall not contain any ferromagnetic particles, large non-insulating aggregates, high levels of carbon, or conductive dyes. The paint should have UV-resistant properties. Most enamel car paint complies with these requirements, the exception being metal flake or metallic paint. A low VOC paint is Sherwin Williams® Polane HS Plus Polyurethane Enamel, the exception being silver paint, which contains metallic particles.

Paint ApplicationRefer to the paint manufacturer’s recommended methods for safe and pr preparation and application methods, including application and safety equipment. Flaking, running or uneven paint thickness varies the antenna performance. Good paint adhesion is affected through surface preparation and cleaning. Break any glossy surfaces using sandpaper or other roughening process. The surface of the radome must be free of grease or contaminates before the paint application.

The ventilation plugs of the antenna must be protected from chemicals used during the preparation process. Do not sand ventilation plugs or allow the plugs to become caked with debris from sanding. Do not paint over the ventilation plugs. The ventilation plugs must be masked before the application of primer or paint. The connectors, ground studs, label, drain holes, and mounting hardware must be protected from paint.

EMS 4.5+ supports the new 3.5 GHz BWX High-powered Basestation Antenna, which is designed primarily to address capacity issues. In some cases Service Providers need to add more users to the same geographic location without adding more antennas, which might not be feasible due to space limitations and would mean incurring additional tower crew installations, etc. When using a BWX High-powered Basestation Antenna with a BWX Basestation Combiner and two BWX 8305 Basestations (BS), the combined power gain is +3 dB. The BWX High-powered Basestation Antenna looks almost identical to a Standard BWX Basestation Antenna.

At this time only the 3.4 -3.5 GHz (3475 to 3600 MHz) frequency BWX High-powered Basestation Antenna is available, supporting the following configurations: BS + BS and a single BS (Figure J-1).

Note When using the BWX 8305 Basestation, the RFC cards must be at a minimum revision level of 91-35300-05 Rev H Radio Frequency Controller with Deviation D00297 or 91-35300-06 Rev F. These revision level cards incorporate Deviation D00297, required to support the H-RFS.

The Service Provider must select adjacent channels when using the BWX 8326 Basestation Combiner with two BSs, i.e., 3.505 and 3.510. The Service Provider may choose to configure both BSs with equal output power; however, the Service Provider also has the option to configure one BS at a higher power level than the other. In either situation, the total combined output power is still 33 dBm (2 Watts). The numbers shown in Table J-1 are an example of how the Service Provider would set the power level for one BS higher than the other.

The output power of a BS is 21 dBm. For every decibel over 30 (P2), you will subtract 1 dB cable loss for BWX High-Powered Basestation Antenna (Table J-2).

Note Prior to EMS 4.5, power could not be set over 30 dB (warning message). EMS 4.5 includes a check box to indicate the antenna is an BWX High-Powered Basestation Antenna. When checked, the EMS will allow the Service Provider to set the power to 33 dB.

The physical installation of an BWX High-Powered Basestation Antenna is 100% the same as with a Standard BWX Basestation Antenna. The installer calibrates in the same way, sweeps the BWX Basestation Antenna in the same way, etc.

• BWX 8326 Basestation Combiner User Guide

Cisco offers a multi-carrier BWX 8326 Basestation Combiner ( Figure K-1)that combines the RF signals from two different Basestations (Figure K-2) into one antenna cable, i.e, RG-6, and then transmits both sets of signals through one BWX 8305 Basestation Antenna. At this time the Combiner is available for 3400 to 3610 MHz frequencies only.

Figure K-1 BWX 8326 Basestation Combiner

In existing sites, using a BWX Basestation Combiner is an economical way for Service Providers to increase cell site capacity, and to avoid cost by not having to add another BWX Basestation Antenna when a BWX 8305 Basestation (BS) is added to the site. As BSs evolve to multi-carrier systems, the BWX Basestation Combiner enables Service Providers to install a single BWX Basestation Antenna for multi-carrier operation.

Figure K-2 Combiner to Basestation Connectivity

While inserting the BWX 8326 Basestation Combiner into an existing site increases capacity at that site, if using a Standard TTA BWX Basestation Antenna, the power loss introduced by the Combiner will degrade the coverage area by up to 30% (since the Combiner is splitting the power between the two BSs). The insertion loss of the BWX Basestation Combiner is 5 dB. However, when the BWX Basestation Combiner is used with a BWX High-powered Basestation Antenna, together they produce up to +3 dB more power output. The output power of a standard BWX Basestation Antenna is 1 Watt per carrier. The output power of a BWX High-Powered Basestation Antenna is 1 Watt per carrier, for a total of 2Watts.

The BWX Basestation Combiner unit fits easily into a standard 19” telecom rack, typically where the Basestations are installed. Its dimensions are 1.7" H x 19.0" W x 10.4" D and is equivalent to one Rack Unit (RU) high.

This is an example of the Regulatory label (Figure K-3)affixed to the bottom of the BWX Basestation Combiner unit. It provides identification information and appropriate Regulatory approvals for that unit.

Note The professional installer may want to inspect the label before installation, as thereafter his view of it may be obstructed.

Figure K-3 BWX 8326 Basestation Combiner Regulatory Label

Physical InstallationThe BWX 8326 Basestation Combiner is an indoor unit that acts as a passive device and is treated much like a cable in the configuration of the Basestation. It does not use any power supply, and it does not have software loaded on any of its components. Before installing it, the BWX Basestation Combiner unit and its cables must be swept in the same way that the RF cables and BWX Basestation Antenna are swept for power loss or gain.

The BWX Basestation Combiner has 27 ports with QMA connectors: 3 connections for each of the 9 BS cables (8 RF cables and the Cal cable). The first BS (called ‘BTS A’ on the Combiner) uses the red connections on the front of the Combiner. The second BS (called ‘BTS B’ on the Combiner) uses the blue connections on front of the Combiner. The black (middle) port is the output port sent to both BSs as the signal comes from the BWX Basestation Antenna to the BSs (see Figure K-4). There is also one group of three ports in the middle of the BWX Basestation Combiner faceplate that are used for the Calibration Cables. The BWX Basestation Combiner requires two sets of 9 Jumper cables with QMA – QMA connectors. A third set of cables with N - QMA connectors go from the BWX Basestation Combiner to the Arrestor Bar. The cables are sold separately from the unit itself.


OL-16336-02

Appendix K BWX 8326 Basestation Combiner (3400 to 3625 MHz)Operation

Figure K-4 Faceplate Ports

Note When installing the BWX Basestation Combiner with only one BS initially, it is required that you cap the other nine (9) ports (BTS-B) with 50-Ohm terminators, as a precaution against signal loss. A termination kit can be purchased separately from Cisco.

Note The cables from the BS to the BWX Basestation Combiner (QMA - QMA) and the cables from the BWX Basestation Combiner to the Arrestor Bar (QMA - N type) must be LMR-240. Theses cables can be purchased separately.

OperationThe circuit card inside the BWX 8326 Basestation Combiner is basically made up of 9 two-way passive RF power dividers with lightning protection built-in to the antenna ports. A 10.7 MHz detector is incorporated on each Basestation connection to the BWX 8326 Basestation Combiner. The detectors determine the Time Division Duplex (TDD) timing sequence using an on/off oscillator and control the frame timing. The two BSs whose RF signals are combined must be in sync with one another by using the same timing sequence: 5 ms framing (802.16e/Mobile WiMAX).

The BWX 8326 Basestation Combiner differentiates the incoming RF signal when the configuration has two BSs (Figure K-5). It monitors the 24 VDC coming in from each BS RF port and applies 10.7 MHz voltage to all 16 RF output ports simultaneously. The combined signal then goes to the Power Amplifiers in the BWX Basestation Antenna to be amplified and transmitted.

If a particular port fails to provide the 24V signal input, that port is assumed to be inoperable and is set to an “invalid” state. Such a state may be caused by the Service Provider taking that RF element out of service, having a broken or missing cable, or due to the entire BS being powered down.

Figure K-5 2 BWX 8305 Basestation Configuration







OL-16336-02

Appendix K BWX 8326 Basestation Combiner (3400 to 3625 MHz)Cable Loss Consideration

Cable Loss ConsiderationWhen a BS is used with an BWX Basestation Combiner, any Antenna Cable Loss greater than 27 will generate an RFC Configuration alarm. This is due to a threshold of 32 dB in the software that does not yet compensate for the Combiner loss of 5 dB. The work-around is to not set the BWX 8305 Basestation Antenna Cable Loss above 27.

CalibrationTo calibrate a BS using a BWX 8326 Basestation Combiner and two BSs with only one BWX Basestation Antenna requires controlling the signals so that the two BSs do not interfere with each other. During calibration the Combiner transmits only for the BS that is undergoing calibration, while ignoring any transmit signals from the other BS. Each BS is determined to be in transmit or receive mode according to the number of active RF ports (Table K-1).

The majority of RF transmissions determine when one of the BSs transmits versus receives. Once one BS does that, the other BS also transmits or receives. During calibration only one BS controls power to theantenna. A transmit state is equal to the absence of a 10.7 MHz signal for a given antenna path. A receive state is equivalent to the presence of 10.7 MHz signal on the antenna path. Since during calibration the antenna only transmits, transmit takes precedence over receive. For a few milliseconds, there is no uplink available for SSs.

In EMS Release 4.5 or later, the EMS will determine and manage the master/slave relationship between the two BSs to control calibration. The EMS will also monitor the health of the BWX Basestation Antenna. At any given time only one BS should be in charge of the output power to the BWX Basestation Antenna.

MaintenanceThe BWX 8326 Basestation Combiner is a single unit that has no field replaceable parts. If a BWX 8326 Basestation Combiner breaks, you simply uninstall it and replace it with another unit. A broken unit will not send an alarm to the EMS or otherwise give a visible indication that there is a component issue. However, the Service Provider will likely see degradation in antenna gain and, therefore, subscriber service if the BWX 8326 Basestation Combiner is not functioning properly. Generally, one of two things can happen to cause a failure in the BWX 8326 Basestation Combiner. A broken component or cable does not pass RF signal or a BS fails to calibrate because it cannot detect transmit from receive status.

As with all electronic components, the unit must be maintained within standard operating temperatures and climates, the same as those set for the BSs (Table K-2).

P P E N D I X L Software Upgrade Procedures (Example)
Reference: Cisco OS Release Notes (specific to each software version)

This appendix provides an example of the software upgrade or downgrade considerations for a BWX Mobile WiMAX system. Do not use these instructions, as they may be outdated. Please refer to the appropriate Cisco OS Release Notes specific to the software version you are deploying.

IMPORTANT! Read all instructions thoroughly, including previous Release Notes and Addendum, before starting an upgrade or downgrade procedure. Always refer to the latest release notes corresponding to the system you are running.

If any alarms or errors occur during or after the upgrade, please check the Appendix for Known Product Issues. If the Appendix does not include the problem you are seeing, please contact Cisco TAC (1-800-553-2447).

Caution As of Release 4.4.2, there are new computing requirements for the EMS Server and Client machines. This is applicable to both Windows OS and Unix OS machines.

Software UpgradesIn licensed frequencies the BWX 8305 Basestation (BS) is upgraded following the associated software release notes. However, in an unlicensed environment (or any network running Enhanced Nulling software) extra precautions must be taken to migrate from EN to JD load during the P2 to P3 network expansion or replacement. As mentioned previously, the BS is offered only with JD software and not EN because of the WiMAX standard profiles. A Service Provider who is adding BSs to an existing 2.4 GHz EN network or replacing Classic equipment with BS in an unlicensed environment running EN software should review the information provided here, and follow the recommended procedures in addition to the standard procedures provided in these release notes.

L-1tation Installation and Commissioning Guide

Appendix L Software Upgrade Procedures (Example)Software Upgrades

Software Upgrade BehaviorIt may be helpful to review how SSs handle software in order to plan and execute a clean EN to JD migration or expansion. During an initial upgrade to JD, after an SS receives the new load it will perform a Swap & Reset. This means the standby side of its flash memory, now containing the new JD software, becomes the Active side. It will try for 2 minutes to connect to the Basestation using the JD software before swapping back to the Standby side with the EN load. If an SS has been turned off and then powered back up after it received the new JD load, it will try for 2 minutes to connect to the Basestation before swapping back to the EN load. If the BS is not available for longer than 4 minutes and is, therefore, unable to service the SS, the SS will try to connect to the Basestation using its Active side running JD software. Then, if it does not make a connection, after 2 minutes it will swap to the EN load and try again. This time, if it fails to make a connection it will fall back to JD and remain there for 15 to 20 minutes before swapping back to the EN load again.

PlanningOnce a BS is installed and running JD software, any SS still running an EN load will not be able to communicate with the new BS. This means that the Service Provider will need to upgrade all SSs associated with that BS (or otherwise in the same geographical area) to a JD load prior to turning up the new BS. To accomplish this the Service Provider should plan and communicate the actions to be taken over a specified period of time. Following are some guidelines and explanations to help Service Providers with planning this upgrade.

• Review these entire procedures.

• Determine the number of end-users who will be impacted by the upgrade to JD. To establish a list of end-users, you can use your own customer service records; or check the number of registered users on an existing TTA system at the same site where BS will be installed; and/or export all SS data, identifying those SSs assigned to that BS.

• Plan the timeline for executing each phase of the upgrade campaign.

• Communicate the plan to your Technical Support group.

• Communicate to the end-users in advance of upgrading. Tell them to expect some short period of service outage during the upgrade.

• Provide Technical Support staff and, if needed, end-users with the tools they will need during the upgrade: BWX Modem Diagnostics tool (NavDiag). The BWX Modem Diagnostics tool is used to display the current Active load on a SS, which may be needed for troubleshooting purposes. Follow the Upgrade Procedures given below that are applicable to your scenario – an expansion installation or a TTA to BWX 8305 Basestation replacement installation.

Upgrade Procedures

Expansion Installation

When adding a BS and BWX Basestation Combiner to expand capacity at an existing BS site, follow these steps:

Step 1 Install and commission the new BS system. Refer to the installation procedures in the BWX 8305 Basestation Installation & Commissioning Guide.

L-2BWX 8305 Basestation Installation and Commissioning Guide

OL-16336-02


Step 2 Download the Joint Detection CPE software to the new BS.

Step 3 From the EMS initiate a CPE Auto Upgrade for the existing BS. Do NOT enable the Upgrade Standby Load option.


OL-16336-02


Step 4 After a pre-determined amount of time, check to see how many SSs have upgraded successfully. To do this, run an SS search against both the BSs. Some SSs may not register successfully with the new BS if the receive signal strength is better with the existing BS.

Step 5 Using the EMS, download the Basestation JD software to the target BS.

Step 6 Perform a Swap & Reset to switch the existing BS to the JD load.

Step 7 Verify that the SSs on the existing BS successfully register, communicate, and pass traffic.

Step 8 After a pre-determined period of time, upgrade the Standby side of all SSs to the JD load using both the existing BS and the new BS. Again, you may have to unicast to upgrade the Standby side of some SSs.

Replacement Installation

If you are replacing a Ripwave TTA Basestation with a BWX 8305 Basestation, follow these procedures:

Step 1 Download the Joint Detection CPE software to the Ripwave TTA BTS.

Step 2 Using BWX EMS initiate an SS Auto Upgrade. Do NOT enable Upgrade Standby Load.

Step 3 After a pre-determined amount of time, check to see how many SSs upgraded successfully. To do this, perform an SS search for the target Ripwave TTA Basestation. If the percentage of SSs that upgraded is high, it may be acceptable to convert the Ripwave TTA Basestation to JD. If the percentage is not very high, you should probably continue the Auto Upgrade. For SSs in lower signal areas you may need to unicast or use the Update Tool provided by Cisco to perform a local conversion from EN to JD.

Step 4 Using the BWX EMS download the BTS JD software to the target Ripwave TTA Basestation.

Step 5 Perform a BTS Swap & Reset to switch the Ripwave TTA Basestation to the JD load.

Step 6 Verify that all SSs successfully register, communicate, and pass traffic.

Step 7 After a pre-determined period of time, upgrade the Standby side of all SSs to JD. Again, you may have to unicast to upgrade the Standby side of some SSs.

Step 8 After a pre-determined period of time, replace the Ripwave TTA Basestation with the BWX 8305 Basestation.
