Installation Guide v1.0 - 4 -

1 INTRODUCTION

This document is intended to provide basic guidance for properly installing an

AxxceLTETM eNodeB. This device is an integrated unit, combining the base station

network functions and radio control functions. The AxxceLTETM family of products also

make this functions available in separate units: the AxxceLTE BBU and AxxceLTE

RRH. Please contact Axxcelera Support for additional documentation of these products.

The first few sections of this document will explain the product along with the connection

and cabling that will be required while the last few sections will cover the physical

installation of the device(s), basic configuration of the eNodeB and antenna installation.

1.1 Exposure Warning

When servicing equipment and selecting a location for the AxxceLTE antennas, it is

important to note that a minimum distance of 138 cm (55 inches) is required between

personnel and AxxceLTE antennas to comply with a radio-frequency exposure limit of

5.0mW/cm2 (47 CFR 1.1310 Table 1, (A) Limits for Occupational/Controlled Exposure).

1.2 Environmental Cautions

• Ambient Temperature – The eNodeB and antennas are outdoor equipment that are

designed to operate over a temperature range of -40C to +55C.

• Reliable Grounding – Reliable grounding of the equipment should be maintained.

Particular attention should be given to supply connections other than direct connections

to the branch circuit (e.g. use of power strips).

• Power Requirement – Each AxxceLTE product is labelled with its specific power

requirement. All outdoor AxxceLTE units are designed for use with a -48VDC supply,

and can function in the range of -40VDC to -60VDC. The integrated AxxceLTE eNodeB

has the largest power requirement at a maximum of 300watts, or 6.25A @ -48VDC.

2 eNodeB Product Overview

2.1 AxxceLTETM family of LTE Products

The Axxcelera Broadband AxxceLTETM system is a broadband, fixed, wireless access

network for Internet, data, video and voice applications. AxxceLTE products can

enhance or replace existing networks, wired or wireless, or be used to deploy new

networks in areas that are historically to cover with traditional wireless systems. The

system is designed to be modular in nature and as such, individual components can be

deployed in an existing LTE network or the entire suite of products can be deployed to

create a new LTE network.

The AxxceLTE eNodeB offers:

· Multi-sector support in an all-outdoor installation footprint

· Flexible deployment options

· Optimum operational simplicity and efficiency

· Configurable high performance MIMO radio of either 2x5W or 4x5W.

· Multiband operation: 700MHz to 3.8GHz

· Integrated Metro-Ethernet switch

· Provides optional remote electrical tilt and 1GbE Power-Over-Ethernet

interfaces

2.2 eNodeB Topology

The eNodeB funtionality is accomplished by two components – the Base Band Unit

(BBU) and the Remote Radio Head (RRH). The BBU manages the telecom network

connection, system administration, and LTE protocols, while the RRH is the RF

transceiver and signal power amplifier.

The BBU is available in three form factors: a 1U rack-mount indoor unit (model number

prefix “ABB”), an outdoor unit (model prefix “ABA”), or an integrated unit which also

contains a complete RRH (model “AEN”). Meanwhile, the RRH is available only in

outdoor models, either stand-alone (model “ARR”) or integrated with the BBU.

This modular system architecture offers very flexible deployment options. For example,

the BBU has (3) external CPRI ports that can be used to connect up to (3) Remote Radio

Heads per eNodeB. These can be deployed in a daisy-chain or star topology. The unit

has field-serviceable SFP modules for single/multi-mode fiber connections. In addition,

the BBU has (2) optical SFP ethernet connections for uplink communications to the

network. A 3rd ethernet link, using a copper GbE connection, may be used for out-of-

band system management.

2.3 System Components

2.3.1 System Architecture

Figure 3.1 shows a typical LTE network architecture using various eNodeB components

at the tower.

Figure 2.1 – Typical LTE Network Architecture

As is shown in the diagram, the eNodeB is typically deployed at the tower, near any

additional RRH units and antennas that it supports. As the BBU is capable of connecting

to three different RRH units, it would be possible to have a BBU located at one site and

have it connect a RRH at a neighboring site via fiber optic cabling.

The S1 interface exits the UPLINK1 / UPLINK2 port(s) which are field serviceable SFP

ports. The two ports can be used for redundant S1 connections or for connecting to 2

different μEPCs.

2.3.2 Time synchronization

Included with the eNodeB is a GPS receiver for time synchronization. Connecting the

receiver to the BBU “GPS” port will allow the eNodeB to synchronize its transmissions

with other eNodeB units in the network.

In addition to GPS, the BBU can synchronize using IEEE 1588, or can accept a 1PPS

clock source via the SYNCIN connector.

3 Cabling and Interfaces

This section outlines and describes the various interfaces on the eNodeB. The system is

designed to be modular in nature and as such, there are many ways the BBU/RRH can be

deployed to accomplish the goals of your network design. Figure 5.1 – 5.3 illustrate

several ways the eNodeB can be deployed.

4 Mounting

The face of both the RRH and BBU casing have (4) mounting points for attachment to

the hanging brace. The AxxceLTETM eNodeB package includes all necessary mounting

bracket hardware to allow for wall or pole mounting the unit. Instructions for mounting

the eNodeB in either configuration are included with the mounting bracket. Please

follow all instructions provided with the mounting hardware.

Be certain to mount the eNodeB in the direction indicator markings on the case itself.

The connector panel must be on the bottom to minimize any potential water ingress to the

case. Failure to mount the eNodeB properly may result in serious damage to the unit.

Figure 4.1 shows the eNodeB mounted to a pole.

Figure 4.1 – eNodeB Pole Mounted

Using the same bracket hardware, the eNodeB can also be mounted to a wall. For wall

mounting, the rear-most part of the bracket and the threaded rods are not used, and the

eNodeB side of the bracket with the stabilizing bar is rotated and mounted to the wall.

Figure 4.2 shows the eNodeB mounted to a wall.

AxxceLTE eNodeB

6 Basic Configuration

Following installation and power up, you are now ready to begin configuring your

eNodeB. This section will outline several basic configuration steps necessary to allow

you to connect to the device. For more detailed configuration information, please see the

AxxceLTE Application Console User Manual.

6.1 Setting the eNodeB IP Address

Once the eNodeB has been installed and power has been applied, you will need to set an

IP address on the device. As previously described, there are two components to the

eNodeB – the BBU and the RRH. Each component requires a unique IP address so it can

be properly managed following installation.

Base Band Unit

To perform a basic configuration of the BBU, use the AxxceLTE Application Console

software to access the device. The default IP address of a base band unit is

192.168.100.200. Change the IP address of the BBU via the Application Console. See

the User Guide for further configuration information.

Remote Radio Head

To perform a basic configuration of the RRH, point a web browser at the device’s default

IP address to access the web management GUI. The default IP address of a remote radio

head is 192.168.100.100

Point your browser at http://192.168.100.100 and enter the credentials:

Username: admin

Password: admin

This will allow you to access management features of the RRH. It is advised to only use

this interface for the purpose of setting the device IP address. Any detailed

configurations should be accomplished using the AxxceLTE Application Console

application.

6.2 Base Band Unit Panel LEDs

7 Antenna Downtilt

To maximize receive signal levels in the intended coverage area, the downtilt angle

should be calculated before the antenna is mounted. This only applies to directional

antennas at the Cell Site. Omni directional antennas should be mounted perpendicular to

the ground. The antenna tilt angle should be determined based on desired coverage area

and any propagation constraints that were determined during RF planning.

Axxcelera has provided a spreadsheet that will calculate the inner and out cell radius

based on antenna height, antenna pattern, and degrees of downtilt. It is important to

understand that this spreadsheet only calculates the 3dB points of the antenna coverage.

Consult the antenna pattern to determine exact coverage at given offsets outside the 3dB

points.

8 Antenna Installation

1. Attach the tilt brackets to the antenna making sure the bracket with the tilt adjustment

slides is installed at the top of the antenna. The top bracket allows -2 to 10 degrees of

downtilt.

2. Once the mounting brackets are installed, attach the antenna to the pole. The clamps

will fit a pole from 48mm – 114mm in diameter.

3. Using an incline meter, verify that the antenna downtilt is the same that is defined in

the RF Plan.
