1 Overview

1.1 Introduction

The Baicells Neutrino-224 product is an indoor 2x125mW small cell eNodeB (eNB) (Figure 1-1). The eNB provides broadband wireless access to 3GPP standard Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD) Long-Term Evolution (LTE) backhaul networks. The Neutrino eNB is the equivalent of a Wi-Fi access point, except that it runs on LTE technology. Using LTE technology ensures an extremely fast, reliable, and secure connection to the network.

The Neutrino eNB makes use of the current LTE transmission resources to enable low-cost coverage and increased capacity for up to 48 (FDD) or 32 (TDD) concurrent users. The small-sized eNB is easy to deploy. Each eNB comes pre-configured so that installation is simplified and connection to the core network can be plug-and-play.

Figure 1-1: Neutrino-224 eNB

Baicells provides a local and Web-based Graphical User Interface (GUI) application to configure and manage the eNB. Baicells also provides a cloud-based solution called CloudCore, which enables service providers with an account to access network management applications through the Internet. The Baicells CloudCore provides an Operations Management Console (OMC) for element management across multiple sites and a Business and Operations Support System (BOSS) for subscriber management.

NOTE: All GUI applications (UE GUI, eNB GUI, OMC, BOSS) are documented in the Baicells Configuration & Network Administration Guide. However, the Neutrino eNB is a newer product based on the latest development software; the eNB GUI and OMC menus and fields may differ from other Baicells products.

2 Planning

2.1 Network & Site Planning

When installing multiple Neutrino eNodeBs (eNBs) in the same general location, for example to cover an entire floor of a building, you will need to perform network and site planning to ensure that all target areas are properly covered for wireless service. Radio Frequency (RF) performance can be diminished by numerous factors, including interference from other eNBs and other radiating devices, and the existence of walls or other obstructions.

You need to consider the density of users and the required capacity to meet their needs. The selected frequency, power, and other settings also affect RF performance. For these reasons, you should perform a site survey and plan the distance between eNBs. A site survey may be ad hoc, or you may wish to use a third-party site survey and RF planning application, or you can hire professionals to complete the planning.

Other types of network planning involve IP addressing; the selection of unique network and cell site identifiers that are used when configuring LTE networks; and for each installation site, the availability of a power source as well as proximity to the local gateway equipment.

2.2 Mounting Options

The Baicells Neutrino-224 eNB was designed for easy deployment. The unit can sit on a desktop or be installed on a ceiling or a wall.

Before placing or installing the eNB at its final location, Baicells recommends that you connect power to the unit in order to verify the status of the PWR LED indicator. How to do this is explained in section 3.

2.3 Client Computer Requirements

Table 2-1 describes the client computer requirements for accessing the Neutrino eNB GUI app. As part of the initial installation of the eNB, typically you will need to use an Ethernet cable to connect the local computer to the eNB LAN port.

3 Verify Basic Operation Before installing the Neutrino eNodeB (eNB), especially if placing it on a ceiling or wall, you should check that:

• You have all of the parts on the packing list;

• You have the standard tools at hand to perform the installation; and

• The eNB unit will power on successfully.

This section walks you through the steps of verifying that the Neutrino eNB is operational and ready for installation.

3.1 Connect Power Cable

Refer to Figure 3-1 to connect power to the eNB. Connect the power adaptor to the power (PWR) port on the unit, and plug the other end into an AC power outlet.

Figure 3-1: LEDs & Interfaces

3.2 Power On

Power on the Neutrino eNB. The PWR LED should light up with a steady white light, as described in Table 2-3 above. The other LEDs will not activate or may display alarm status pre-installation. You will be checking those LEDs later in the process once the installation and basic configuration steps are completed.

If the eNB does not power on or the PWR LED is not lit up, please verify that the connection setup is correct. Otherwise, contact your supplier immediately for a replacement.

sredfoot

I changed the installation order from the China version guide. I have the installer first verify the eNB will power up ok before installing the physical unit on a ceiling or wall. Let me know if this makes sense.

15

4 Mounting the Unit This section covers how to install the Neutrino eNodeB (eNB) on a ceiling or wall. If you completed the steps in section 3 Verify Basic Operation, as recommended, uninstall the power connections from the eNB before installing the unit on a ceiling or wall.

4.1 Preparation

If you plan to install the Neutrino eNodeB (eNB) on a ceiling or wall, you will need a marker pencil and a percussion drill to install the bracket that holds the eNB. Go to section 4.2 for a ceiling installation, or to section 4.3 for a wall installation.

Some operators may want to add a GPS antenna to ensure accurate physical location information used by the eNB during transmissions. To connect the antenna you will use the GPS interface on the eNB. Follow the GPS vendor’s installation requirements to install a GPS antenna with the Baicells Neutrino-224 eNB.

4.2 Ceiling Installation

Review the following guidelines for installing the Neutrino-224 eNB unit on a ceiling. The installation steps follow.

The thickness of the ceiling should be no less than ½ inch/18 mm, and should be able to bear more than 11 lbs/5 kg weight.

If the ceiling is made of weak materials, such as a gypsum, this installation method is not recommended. Because of the environment restrictions, to continue with a ceiling mount in this situation add one layer of stronger panel under the screws to make sure the device is secure.

1. Attach the bracket under the Neutrino eNB unit using the M3*10 cross round head screws (Figure 4-1).

Figure 4-1: Attach Bracket

2. Remove the selected ceiling panel.

16

3. Place the bracket on the center of the ceiling panel, and mark the drilling hole locations with a marker pen (Figure 4-2).

Figure 4-2: Mark Drilling Holes

4. Drill the 3 holes that you marked, deep enough to receive the expansion bolts.

5. Use the expansion bolts to fix the installation bracket on the ceiling panel, and tighten the screws (Figure 4-3).

Figure 4-3: Fix Bracket to Ceiling Panel

6. Slide the Neutrino unit onto the bracket according to the arrow indicator (Figure 4-4). Proceed to section 4.4.

Figure 4-4: Attach Unit to Bracket

4.3 Wall Installation

The steps for installing a Neutrino eNB on a wall are the same as when installing it on a ceiling, as covered in section 4.2 Ceiling Installation, with the exception that you will need to adjust the direction of the arrow on the bracket according to the wall placement. Be sure the 3 holes for the bolts are in the correct position.

Proceed to section 4.4, next.

4.4 Connect Cables

Connect the power adaptor to the unit and outlet, as explained in section 3 Verify Basic Operation. Do not power on the unit yet.

Connect an Ethernet cable to the WAN port on the unit; the other end connects to the backhaul device.

4.5 Power on

Power on the Neutrino eNB. It may take a minute or two for the LEDs to provide status information. Refer to Table 2-3 LED Status to ensure the PWR LED is showing a steady white light. The other LED will be more accurate after you complete the basic configuration, which is discussed in section 5 Configuration.

4.6 Check eNB Status in Software

The Baicells eNBs are designed to be plug-and-play and, therefore, arrive with many parameters pre-configured using default values. You will need to connect a computer to the LAN port using an Ethernet cable to ensure the eNB status is reported as active before you continue with the installation.

4.6.1 Computer Requirements

The client computer you use to interface with the LAN port on the eNB must meet the following minimum requirements shown in Table 4-1.

5.5 LTE Setting

Caution: Baicells recommends that you DO NOT modify these advanced LTE parameters; keep the default values.

The LTE Setting parameters are important for efficient wireless network operation (Figure 5-22). The information pertaining to the LTE Setting menu is broken into two sections: “Neighbor Cells & Mobility” (section 5.18.1), and “Other LTE Settings” (section 5.18.2).

It is a good idea to review all of the LTE Setting information to understand how the configuration settings relate.

sredfoot

I included some material from the TDD-based eNB GUI config guide. Please review all of this section to ensure the information is relevant for Neutrino and for FDD.

45

Important: If you make any changes to the LTE Setting parameters, you must reboot the eNB for the new configuration to take effect. A reboot action will disrupt service.

Figure 5-22: LTE Setting

5.5.1 Neighbor Cells & Mobility

5.5.1.1 Planning

Under LTE Setting you will establish the neighboring eNBs operating in the same geographical area as the eNB that you are configuring. This information is completed for each eNB so that the eNBs collectively work well with one another to handle mobile users and to balance the traffic load.

Under the LTE Setting menu, you will (a) configure the neighboring eNBs’ frequencies and identify each eNB running on that frequency; (b) configure the current eNB’s mobility parameters; and (c) examine the current eNB’s advanced settings. Note that many, if not all, of the advanced settings should be left with their default values; any modification should be determined only by experienced wireless professionals.

Additional LTE Setting sub-menus are explained in section 5.17.2 Other LTE Settings.

Important: Make sure the current and neighboring eNBs are GPS enabled and synchronized.

5.5.1.2 Identify Neighboring eNBs

Potentially, there are 3 types of neighboring eNBs based on the type of technology they use to operate:

• Other LTE eNBs

• 3G mobile eNBs, which use Wideband Code Division Multiple Access (WCDMA)

• Global System for Mobile (GSM) eNBs

The LTE Setting menu provides a sub-menu for each of these types of eNBs.

46

For each type of neighboring eNB, you will first add the neighbor frequency settings via the Neigh Freq List, and then you will add the cell information associated to the frequencies via the Neigh Cell List.

You can configure the Neigh Cell List for both inter-frequency (between different frequencies) and intra-frequency (within the same frequency) neighboring eNBs. For inter-frequency cells, you must add the neighbor inter-frequency settings in the Neigh Frequency List before you try to add the neighbor inter-frequency cell (eNB) information. Conversely, if you need to delete a neighbor inter-frequency record, you must first delete the neighbor inter-frequency cells (eNBs) associated to it.

For an intra-frequency neighbor cell, meaning a neighbor eNB operating on the same frequency as the eNB you are configuring, you do not need to configure the Neigh Freq List, but you do need to configure the Neigh Cell List.

5.5.1.3 LTE Freq/Cell

Using the LTE Freq/Cell sub-menu, you can configure parameters related to how adjacent eNBs operating with LTE technology work with the Baicells Neutrino eNB that you are configuring. In other words, you will define for the Neutrino eNB how to coordinate with any neighboring LTE eNBs. Up to 8 LTE neighbor frequencies and 32 LTE neighbor cells can be configured.

5.5.1.3.1 Neigh Freq List

1. In the eNB GUI go to LTE Setting > LTE Freq/Cell (Figure 5-23).

Figure 5-23: LTE Freq/Cell

2. Under Neigh Freq List, click on the Add icon to add the neighboring LTE eNBs’

frequencies (up to 8). The fields are shown in Figures 5-24 and 5-25, and described in Table 5-13. Click on Save after setting the values.

5.5.1.6 Mobility Parameter

The Mobility Parameter menu pertains to how roaming UE sessions are handled between different eNBs in the same service area. When a UE is actively connected to an eNB, the current eNB is referred to as the serving eNB or cell. The other eNBs in the area are referred to as either neighbor or target eNBs or cells.

sredfoot

I added content from another eNB config doc written for TDD. Please verify that what I added is relevant for Neutron, for FDD, and for 3G and GSM neighbors if those are supported in this release.

57

The process of a device moving from cell to cell and changing over from its serving eNB to a neighbor (target) eNB is called handoff or handover*. The UE exchanges information with its serving eNB to perform cell selection and reselection based on parameters which you will set for each eNB. Refer to Figure 5-30.

*NOTE: The terms handoff and handover are used interchangeably in LTE.

Figure 5-30: Handoff

What the UE measures that determines cell selection and reselection is the Reference Signal Received Power (RSRP) of the serving as well as neighboring eNBs. The measurements are sent periodically to the serving eNB, which then determines if the UE would be better served by an adjacent eNB.

The default settings in the Mobility Parameter sub-menus (Figure 5-31) can be adapted to most situations. Many of the mobility settings should be left with their default values. Any modification should be determined only by experienced wireless professionals.

In terms of LTE to LTE handoff, only the A1, A3, A5, Measurement Control, Cell Selection Parameter, and Cell ReSelection Parameter fields are used.

If the serving eNB determines that more than one adjacent eNB meets the RSRP event thresholds, the Cell Reselection settings will determine to which adjacent eNB the serving eNB will hand off.

You will configure these mobility parameters for every adjacent eNB. To open one of the threshold areas in the window, simply click on the heading, e.g., A1 Event Threshold, to display the configuration fields. Table 5-19 describes each field. Click on Save to save the configuration data.

5.5.1.7.1 Power Control Parameters

Refer to Table 5-20 for a description of the Power Control Parameters.

Information about power control:

If the transmit power is set to fixed, the value is set to single. If the transmit power management (TPM) is set to enabled, the eNB can adjust its transmit power automatically; only the two values for top and bottom boundaries are set, separated by a comma.

Following is the formula for calculating the reference signal power using total power:

Total power is PTX (mW), bandwidth is Bw (MHz), then the reference signal power pCRS(dBm) is:

pCRS = 10 * lg(PTX) – 10 * lg(12 * 100 * Bw / 20) + 10 * lg(1 + PB)

where:

Bw is the parameter carrierBwMhz under Quick Setting.

PB is the power parameter for Physical Downlink Shared Channel (PDSCH), which is the parameter pb set under the Power Control Parameters. The default is 1.

5.5.1.7.5 Scheduling Algorithm

The Scheduling Algorithm fields are important for smooth RF operation and can impact key performance indicators such as cell throughput, cell edge users, Voice Over IP (VoIP) capacity, and data Quality of Service (QoS). The most common scheduling strategies used are listed below:

QoS - Algorithm based on QoS

PFS – Proportionally Fair Scheduling (PFS) balances between channel quality and user fairness, where both cell throughput and user fairness are considered.

RR – Round Robin (RR) scheduling allocates resources to all UEs equally. Neither QoS nor memory is considered.

This eNodeB Range provides an alternative for the macro/micro cell identification mechanism beyond the default mechanism which is based on PCI range. While enabled, the eNodeB will identify whether a neighbor cell is Macro or Micro based on its eNodeB Identity. If the eNodeB Identity broadcast by the neighbor falls in the range defined in this record, the neighbor will be considered a Micro cell.

The following describes the expression method of the eNodeB ID, where placement of a dash (-) indicates the upper and lower bounds. Use a dash (-) before the lower limit and a dash (-) after the upper limit.

1. Normal: Compare the total eNodeB_ID size. The eNodeB ID range reserved for Micro cell is defined by specifying its lower bound and upper bound, separated by (-) sign.

2. Segment: Compare the eNodeB_ID segmentation. The minimum size of a segment is 4 bits. The upper bound determines the length of a segment; for example, upper bound 7 indicates a segment with 4 bits. The upper bound 100 indicates a segment with 8 bits (96 is greater than 15 and smaller than 255, so 4 bits is not enough - the segment is 8 bits).

If the segment bit length that needs to be set is greater than the bit length of the expressed upper bound, it needs to be filled with [0] before the value. Each [0] indicates 4 bits. If the system needs to compare the segment with 12 bits (range 50 to 200), then the segment needs to be filled in as [0][50-200].

If some segment needs to be ignored, it can be filled with [*]. Each [*] indicates 8 bits. For example, [1-300][*][7-11] indicates the minimum 12 bits is between 1 to 300, the middle 4 bits is any value, and the last 4 bits is between 7 to 11. Another example is [**][0][20-100] indicates the minimum 8 bits is any value, the middle 4 bits is 0, and the last 8 bits is between 20 to 100.

Refer to Table 5-25 for a description of the eNodeB Range fields.
