2 eNodeB Product Overview

2.1 AxxceLTE

family of LTE Products

The Axxcelera Broadband AxxceLTE

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 3

ethernet link, using a copper GbE connection, may be used for out-of-

band system management.
