Overview

Introduction
LEAX LBS8529 is an outdoor 2x20W eNodeB (eNB) that enables wired and wireless broadband access to Long-Term Evolution (LTE) backhaul networks using Time Division Duplexing (TDD) technology. With its power and LTE intelligence, this eNB has exceptional non-line-of-sight (NLOS) coverage performance (Figure 1-1).

LEAX provides operators with local and Web-based Graphical User Interface (GUI) software applications to configure and manage individual eNBs and User Equipment (UE). Additionally, LEAX offers a cloud-based, centralized Software- as-a-Service (SaaS) solution called CloudCore. CloudCore, or LEAXCloud, includes all of the key LTE Evolved Packet Core (EPC) network functions (Figure 1-2), an Operations Management Console (OMC) for managing multiple sites across the network, and a Business and Operations Support System (BOSS) for subscriber management. In this document you will find a general description, guidelines, and procedures for installing, entering basic configuration settings, and verifying the operational status of theLBS8529 eNB. For additional information on configuring features beyond the basic settings, please refer to the “LEAX Configuration Guide for LEAXTRS_3.6 ”.

Installation Preparation

Support Materials
In addition to industry standard tools, you will need the materials described in Table 2-1 during the installation. When selecting an RF antenna, be sure to match the frequency range of the antenna with the eNB.

Table 2-1 Supporting Materials

You will need a computer to connect to the local maintenance terminal (LMT) via the RJ-45 ETH port on the eNB unit. Through the LMT you can access the eNB GUI to enter basic configuration parameters so the eNB can connect to the network and to the LEAX CloudCore.

Installation Tools
The following standard tools may be needed during the installation.

Installation Environment

Location & Environment
In addition to network planning, when determining where to place the eNB you need to consider factors such as climate, hydrology, geology, the possibility of earthquakes, reliable electric power, and transportation access. Avoid locating the eNB in areas where there may be extreme temperatures, harmful gases, unstable voltages, volatile vibrations, loud noises, flames, explosives, or electromagnetic interference (e.g., large radar stations, transformer substations). Avoid areas prone to impounded water, soaking, leakage, or condensation.

Table 2-2 provides typical environmental specifications for this eNB.

Table 2-2 Environmental Requirements

Lightening & Grounding Protection
You must protect the eNB, antenna, and GPS against lightning. All Nova eNBs use a floating ground on the power line. Following are guidelines concerning grounding.

• The yellow-green ground wire must be at least 16mm2 in diameter.
• In principle, always place the grounding as near as possible to the equipment.
• Connect to a reliable outdoor grounding point (earth) using one ground screw.
• The connection of the grounding points and ground bar need to be tight and reliable. Rustproofing the terminals, e.g., with anti-oxidant coating or grease, is required.

Weatherproofing
To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following (Figure 2-1).

1. Insert the cable into the cold shrink tube.
2. Tighten the connector.
3. Push the cold shrink tube to the top joint, and pull out the strip.
4. Ensure the cold shrink tube is tightly fitted with the connection.

Installation

Overview

Figure 3-1 provides an overview of the installation process.

Install GPS Antenna

Read the following GPS antenna installation requirements before installing it on the eNB.

• No major blocking from buildings in the vicinity. Make sure the space atop is at least 45 degrees unblocked by any buildings.
• Avoid installing the GPS antenna in the vicinity of any other transmitting and receiving devices, to avoid interference.
• The GPS antenna should be installed within 45 degrees to the lightning rod.

The GPS antenna system is assembled in manufacturing before packing. The only installation step is to fix the GPS mounting bracket on the eNB with the M4*14 screws (Figure 3-2).

Figure 3-2 GPS Antenna Installation

Install eNB on Pole or Wall
The eNB mounting bracket is assembled in manufacturing before packing. The only action required by the installer is to fix the assembly on the pole. Check to ensure the diameter of the pole is in the range of 1.6-3.9 inches (40-100 mm). The position of the eNB on the pole should be at least 79 inches (200 cm) in height. Follow the steps below to install the eNB on a pole.

1. Unscrew the 4 screws of the assembled bracket. Slide the two omega clamps to the left, and then turn them up or down.

3. Using the 2 pins on the bracket on the back of the eNB, attach the eNB to the mounting bracket on the pole. Push the eNB until the hook is firmly attached to the bracket.
4. Tighten the screws on the top of the bracket using a cross screwdriver to complete the installation.
5. Proceed to 3.5 Connect Cable

Install on Wall
Ensure that the wall can bear at least 4 times the weight of the eNB. Follow the steps below to install the LBS8529 eNB on the wall.

1. Take apart the assembled installation bracket.
2. Fit the installation bracket on the wall, with the arrow pointing up. Mark the drilling locations using a pencil or marker.
3. Drill two .4in/10mm diameter by 2.8in/70mm deep holes in the wall at the marked locations.
4. Insert the expansion pipes.
5. Check the up/down direction of the installation bracket , and then fix it to the wall with M 8 80 expansion screws .
6. Fix the eNB to the bracket, and tighten the screws on the top of the bracket using a cro ss screwdriver.
7. Proceed to 3.5 Connect Cable

2. Lay the Ethernet cable along the wire groove, and stretch out the wiring cavity from ETH hole.

Connect Power Connector
Since the length of cable needed for power varies from site to site, the two ends of the power adaptor are bare terminal ends. You will need to make the power cable according to the actual measurements of the installation site, and assemble the power plug and power terminal on the two ends of the power adaptor. Strip .47in/12mm insulating layer with a wire stripper. The power cord length should be kept below 330 ft/100m. The connection steps for the power cable are as follows.

1. Assemble the power plug.
   The power plug will be installed on the end of the input direction. Refer to the labels on the power plug for connecting the live wire, neutral wire, and ground wire to the corresponding terminals separately, and tighten the screws.

2. Assemble the power terminal.
   The power terminal will be installed on the end of the output direction. Refer to Figure 3-3 to connect the live wire and neutral wire.
   Figure 3-3 Power Terminal
