Azcom AZB Series LTE BBU

Centralized RAN BBU Platform

The AZB-4000 module offers private and public network operators a simple way to implement and enable a cutting-edge Radio Access Network with maximum reuse of existing infrastructure e.g. power, rack space, and footprint for an extremely compelling total cost of ownership (TCO) and optimum time-to-market (TTM).

Flexible and Scalable Design

The AZB-4000 module is based on one of the most advanced and powerful multi-core SoC to run and manage physical layer (L1), L2 and L3 stacks. Access technology specific accelerators provide a simple and reliable way to implement the PHY layer. The high performance SoC is well suited to implement advanced LTE features like NB-IoT, eMTC, carrier aggregation, higher order MIMO, cross carrier scheduling, co-operative multi point transmission and reception, beamforming. Optimization and acceleration engines are also available on the SoC to optimize the data path, improving overall throughput and capacity of the BBU. A pluggable GPU enables embedded implementation of EPC functions and, therefore, realization of a compact LTE NIB solution.

The AZB-4000 supports all the essential high speed communication interfaces like GBe and CPRI. Appropriate configurations of these interfaces can enable multiple, flexible deployment configurations.
