Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved 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.

All rights reserved Figure 3.3 – eNodeB Deployment Scenarios (cont) Depending on how you chose to deploy your BBU/RRH, the cabling can change greatly. Below is a description of each interface on the eNodeB. Each interface is described with its function, connector type and typical connection point on the other end of the cable. This is a guide only and does not attempt to describe every possibility for connection points. 3.

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.
Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved Figure 4.2 – eNodeB Wall mount 4.1 Grounding It is required to properly ground the eNodeB. To do this, a ground lug is provided as a convenient attachment point to the facility grounding plane/grid. It is located on the bottom seam of the case, labelled with the following mark: 4.2 Sun Shield AxxceLTE outdoor products are delivered with a sun shield that can be mounted to either face of the unit using the (4) mounting blocks.

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.
Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved 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.
