General description
2 General descriptionNokia UltraSite EDGE BTS is part of Nokia UltraSite Macrocellular Solution,which delivers macrocellular BTS products complete with transmission andauxiliary equipment. Optimised for high-capacity and wide-coveragemacrocellular applications, Nokia UltraSite EDGE BTS supports both omni-directional and sectorised configurations. It can be used in GSM 900, GSM 1800,or GSM 1900 systems, or as a GSM 900/GSM 1800 dual-band BTS.
Nokia UltraSite EDGE BTS is available in different cabinets for outdoor andindoor applications:
• Nokia UltraSite EDGE BTS Outdoor
• Nokia UltraSite EDGE BTS Indoor
• Nokia UltraSite EDGE BTS Midi Indoor (valuable where vertical space islimited)
For sites with minimised requirements, both the Outdoor cabinet and the Indoorcabinet can hold an Integrated Battery Backup (IBBU). When installed in one ofthese cabinets, an IBBU reduces the maximum number of Transceiver units(TSxx) in the cabinet from 12 to 6.
2.1 Operation
Nokia UltraSite EDGE BTS performs the radio functions of the Base StationSubsystem (BSS). The BTS receives and sends signals through:
• the Air interface — the frequencies that connect the BTS to the MobileStation (MS)
• the Abis interface — a cable or a radio link that connects the BTS to theBase Station Controller (BSC), which is the central element of the BSS
Figure 1 illustrates the BTS interfaces.

General description
Uplink path
The antenna picks up a signal from the MS through the Air interface. The antennapasses the signal to the optional Masthead Amplifier (MNxx) and Bias Tee(BPxx) units or to the optional Dual Duplex Filter unit (DU2x). From there thesignal goes through the optional Dual Variable Gain Duplex Filter unit (DVxx)or the optional Remote Tune Combiner unit (RTxx) to the Receiver Multicouplerunit (M2xx and M6xx), and then to the Transceiver unit (TSxx).
The TSxx unit’s Transceiver module (TRX) converts the signal to IntermediateFrequency (IF) levels and filters the signal. Then the TSxx sends the signal to theTransceiver Baseband unit (BB2x) for digital signal processing.
The BB2x sends the processed signal to the Transmission unit (VXxx), whichpasses the signal through the Abis interface to the BSC.
Downlink path
The BSC receives a signal from the network and sends the signal to the VXxx unitthrough the Abis interface. The VXxx passes the signal to the BB2x unit fordigital signal processing. The BB2x sends the processed signal to the TSxx unit.
The TSxx unit’s Transceiver module (TRX) filters the signal, raises it to thecarrier frequency, and amplifies it. Then the TSxx sends the signal either to theRTxx unit or through the optional Wideband Combiner unit (WCxx) to the DVxxunit. The RTxx unit or the DVxx unit sends the signal to the optional DU2x unitor the optional BPxx and MNxx units.
The DU2x or the MNxx sends the signal to the antenna, which passes the signalthrough the Air interface to the MS.

General description
Radio-link transmission
The radio-link transmission unit for Nokia UltraSite EDGE BTS is the FXC RRIunit. The proprietary Nokia Flexbus, a coaxial cable, is available for transmissionbetween the microwave indoor unit and the outdoor unit.
Nokia Flexbus carries as much as 16 x 2 Mbit/s in both directions, and it alsocarries power for the outdoor unit. It is compatible with Nokia FlexiHopperMicrowave Radio and Nokia MetroHopper Radio, and it can also connect BTSsor transmission nodes at the site. The maximum cable length is 300 meters.
Fibre-optic transmission
The fibre-optic transmission units for Nokia UltraSite EDGE BTS are the FXCSTM-1 and FXC Bridge (always used together). The FXC STM-1 unit uses astandard SDH optical STM-1 interface, which can carry 63 x 2 Mbit/s.
Wire-line transmission
Cellular Access networks have been based mainly on the E1 (ETSI) and T1(ANSI) standards. E1 capacity is 2 Mbit/s; T1 capacity is 1.5 Mbit/s.
Nokia UltraSite EDGE BTS supports those standards with the following wire-linetransmission units:
• FC E1/T1
• FXC E1
• FXC E1/T1
2.2.2 Network topologies
Nokia UltraSite EDGE BTS supports all network topologies directly — loop,chain, star, point-to-point, and mesh. Separate transmission nodes are notnecessary. The BTS cabinet can hold as many as 4 integrated transmission units.
There can be 8 microwave connections in a single-cabinet Nokia UltraSite EDGEBTS and 20 in connections a 3-cabinet site. The transmission can be directlyconnected to Nokia MetroSite GSM BTS through Nokia MetroHopper Radio orNokia FlexiHopper Microwave Radio. Grooming at the BTS further optimizestransmission capacity.
Each BTS cabinet using FXC transmission units can provide add-drop capacityto other sites. The integrated transmission can groom traffic and serve as a PDHloop master. Cross-connections down to 8 k granularity and grooming at the BTSfurther optimise transmission capacity.
DN99440288 © Nokia Networks Oy 15 (46)Issue 1-1 en Nokia Proprietary and Confidential
Base Station Description
One BTS cabinet can provide a Flexbus connection for up to 8 NokiaMetroHopper Radios or Nokia FlexiHopper Microwave Radios, without anyadditional transmission equipment like radio indoor units. With FXC E1/T1 units,the corresponding number of interfaces is 16.
One FXC STM-1 unit has two STM-1 interfaces, each with 63 x 2 Mbit/s. Theunit can be used as an interface to a fibre-optic network or as an indoor unit forNokia UltraHopper Microwave Radio.
The number of connections can be increased when new cabinets are installed.However, the cabinets must be interconnected. The preferred solution forinterconnecting cabinets is Flexbus. Connecting two cabinets requires oneFlexbus interface in each cabinet. Multiple cabinets are connected to the firstcabinet.
Flexbus is used to interconnect the cabinets when a total add-drop capacity of 16x 2 Mbit/s is sufficent. When more capacity is needed, the FXC STM-1transmission can be chained through multiple cabinets for an add-drop capacityof 21 x 2 Mbit/s per cabinet. The FXC STM-1 occupies two slots (FXC STM-1and FXC Bridge units), leaving space for two other transmission units per cabinet.
A co-located Nokia Talk-family BTS can be connected to Nokia UltraSite EDGEBTS using the integrated E1/T1 interface or Flexbus. During the upgrade phase,Nokia Talk-family transmission interface towards the BSC can be used to provideAbis for Nokia UltraSite EDGE BTS. This, however, limits the capacity andexpandability of the BTS. Therefore, it is recommended that the Abis interfacesare connected through Nokia UltraSite EDGE BTS.
The choice among topologies depends mainly on the requirements fortransmission media and availability. The loop topology is the most reliable,providing excellent protection against equipment failures and radio-link fading.
Figure 4 illustrates a loop topology.

2.2.3 Cross-connections
Different transmission nodes support different cross-connection granularities andconnection types in GSM transmission networks. The BTS access networksnormally use 16 kbit/s for signalling and traffic. To fill higher-level transmissionpipes, the nodes must be able to make cross-connections on the 16 kbit/s level.
Nokia UltraSite EDGE BTS can handle the most important cross-connectiongranularities of:
• 8 kbit/s, needed when grooming Abis traffic
• n x 64 kbit/s
• 1.5 Mbit/s, corresponding to the T1 interface
• 2 Mbit/s, corresponding to the E1 interface

2.2.4 Protection
There are several complementary ways of protecting transmission againstproblems such as cable cuts, radio-link fading, and faults in the equipment.
Equipment protection
Equipment protection is used to ensure transmission regardless of faults in theequipment. This means that redundancy is built at the equipment level.
The Hot Standby (HSB) equipment protection for Nokia FlexiHopper MicrowaveRadio can be implemented with either one (FIU19, FXC RRI) or two (FIU19only) indoor units.
Protection of an FXC STM-1 unit can be implemented by installing a redundantFXC STM-1 unit. In the case of a fault in the operating unit or a forced switch bythe management function, the redundant, protecting unit becomes the primaryunit. This changeover is non-reverting.
Path protection
In general path protection, diverse paths for the traffic are configured to protecttraffic against faults. Nokia UltraSite EDGE BTS supports the 1+1 pathprotection where the traffic is sent in two paths simultaneously, and the protectionswitching is done entirely at the receiving end. Nokia UltraSite EDGE BTS doesnot provide support for the 1:1 and 1:N path protection methods.
The SDH multiplexing structure enables efficient path protection schemes. Singlemultiplexer sections as well as VC paths over several multiplexer sections can beprotected independently. The multiplexer sections may contain severalregenerator sections.
The FXC STM-1 units configured as Add/Drop Multiplexer (ADM) are capableof VC-12 level SNC/I (inherently monitored sub-network connection) protection.In multiplexer section protection the FXC STM-1 uses the single-ended switchingmode where both directions of transmission operate independently.
Loop protection
For connection protection to be efficient, diverse routes for the paths are needed.Loop or ring network structures are the most appropriate for this purpose. Loopsare a very efficient way to protect against failures in transmission path andequipment.
DN99440288 © Nokia Networks Oy 19 (46)Issue 1-1 en Nokia Proprietary and Confidential
Base Station Description
PDH loops with Nokia elements are implemented by a Nokia proprietary master-slave principle. The transmission direction in the loop is selected by using specialpilot bits. The pilot bits can be configured to be used as any bit in the 2 Mbit/ssignal. The loop master sends the pilot bits and thus controls the transmissiondirection of the loop.
SDH equipment provides efficient add/drop multiplexers without separate up anddown multiplexing. The ADMs can be used efficiently to provide automaticallyprotected transmission loops. The FXC STM-1 unit has two STM-1 interfaceswhich enables easy loop implementation. In later releases, FXC STM-1 can beused for interconnecting two loops.

• cabinet control
4.3.2 Dual Band Duplex Filter unit
The Dual Band Duplex Filter unit (DU2x) combines outputs from GSM 900 andGSM 1800 DVxx or RTxx units into one antenna feeder.
4.3.3 Transceiver Baseband unit
The Transceiver Baseband unit (BB2x) is a digital signal processing board,consisting of two independent baseband modules; each module functionsindependently for its own TSxx unit. The BB2x also controls frequency hopping.
4.3.4 Dual Variable Gain Duplex Filter unit
The Dual Variable Gain Duplex Filter unit (DVxx) performs duplex operation ofTX and RX signals into a common antenna, and provides filtering andamplification for main and diversity receiver signals before they go through theM2xx or M6xx unit to the TSxx unit. The DVxx unit contains a variable-gainLNA for optimal amplification of the receive signal, with or without the optionalMasthead Amplifier.
4.3.5 Integrated Battery Backup
The optional Integrated Battery Backup (IBBU) ensures a continual power supplyif the main AC power fails. The IBBU can produce power for as many as 18 TSxxunits in two BTS cabinets. It occupies the bottom of Nokia UltraSite EDGE BTS.

Base Station Description
4.3.6 Masthead Amplifier and Bias Tee units
Masthead Amplifier unit
The Masthead Amplifier unit (MNxx) delivers 33 dB RX gain in GSM 1800/GSM 1900 units and 32 dB RX gain in GSM 900 units, low RX noise figure(improved RX sensitivity and signal-to-noise ratio) and low TX loss in a compact,low volume, light-weight sealed enclosure. To use the MNxx, the Bias Tee unitis required.
Bias Tee unit
The Bias Tee unit (BPxx) provides DC power, through an RF cable, to the MNxxunit. There are two versions of the BPxx unit:
• BPxV — Bias Tee with Voltage Standing Wave Ratio (VSWR) antennamonitoring, which checks the antenna line’s condition and gives an alarmif the VSWR value exceeds the limit
• BPxN — Bias Tee without VSWR antenna monitoring
The BPxN (without VSWR) is used solely with the MNxx, while the BPxV (withVSWR) can be used with or without the MNxx.
4.3.7 Receiver Multicoupler unit
The Receiver Multicoupler unit (M2xx and M6xx) distributes RX signals to TRXRF units. The 2-way unit (M2xx) is used in most WCxx or combining by-passconfigurations. The 6-way unit (M6xx) is always used with an RTxx unit. Oneunit performs signal splitting for both main and diversity branches.
4.3.8 Power Supply unit
The Power Supply unit (PWSx) converts input AC or DC voltage to the differentDC voltages required for the various BTS units. Then it distributes theappropriate voltages through the backplanes to the units — except for the optionalHeater unit (HETA), which receives its voltage from the AC mains through thepower filter module. The PWSx unit also supplies power for the MastheadAmplifier unit (MNxx).
Nokia UltraSite EDGE BTS can hold two AC Power Supply units (PWSA) orthree DC Power Supply units (PWSB). The PWSA supports full redundancy foras many as six TSxx units. The PWSB supports full redundancy for as many as12 TSxx units.

Units
4.3.9 Remote Tune Combiner unit
The Remote Tune Combiner (RTxx) combines up to six transmitter outputs intoone antenna. It also provides filtering and amplification for main and diversityreceiver (RX) signals before they go through the M2xx or M6xx unit to the TSxxunit.
The RTxx unit contains a variable-gain LNA for optimal amplification of thereceive signal. The high-gain LNA is fixed, and is used without the optionalMNxx unit. The low-gain LNA is variable, and is used only with the MNxx unit;the low-gain LNA is set according to antenna cable attenuation values.
A duplexer is built into the RTxx, so no DVxx unit is required.
4.3.10 Temperature Control System
Unit Cooling Fans
The Unit Cooling Fans are included in the cabinet core. The BOIx unit controlsthe fan units according to temperature information from other units. The coolingis performed by adjusting the rotation speed of the fans. Smooth speed variationsalso minimise the noise generated by the fan units.
Heater unit
The optional Heater unit (HETA) is needed in Nokia UltraSite EDGE BTSOutdoor to cold-start the BTS when operating in temperatures between -10 and -33°C (+14 to -27°F). It will also maintain interior cabinet temperature duringextreme cold operation.
Cabinet Cooling Fan
The Cabinet Cooling Fan is included in the Outdoor Application Kit (OAKx), andis mounted in the cabinet door.
4.3.11 Transceiver unit
The Transceiver unit (TSxx) consists of one transmitter, one main receiver, andone diversity receiver.
