Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved AxxceLTE eNodeB 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.
Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved AxxceLTE eNodeB Installation Guide v1.0 - 5 - 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.

All rights reserved AxxceLTE eNodeB Installation Guide v1.0 - 6 - 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.
Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved AxxceLTE eNodeB Installation Guide v1.0 - 7 - 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.

Copyright 2015 Axxcelera Broadband Wireless, Inc. All rights reserved AxxceLTE eNodeB Installation Guide v1.0 - 18 - 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. FIGURE 7.1 – CELL SITE ANTENNA DOWNTILT FIGURE 7.2 – ANTENNA DOWNTILT SPREADSHEET
