Product Positioning and Features
This document provides a description of ZXSDR B8200 (hereinafter referred to as B8200), which is a Base Band Unit (BBU) used in ZTE's multi-mode wireless solutions.
The B8200 can be installed into an integrated macro base station, or connected to RRUs to constitute a distributed base station.It is responsible for processing baseband signals.Based on ZTE's innovative Software Defined Radio (SDR) platform, it supports GSM, UMTS, LTE, NB-IoT or their combinations through software configuration.It enables operators to deploy one unified radio access network rather than independent GSM, UMTS, LTE and NB-IoT networks, which brings simplicity and convenience with low CAPEX and OPEX.
In this document, G is short for GSM, U is short for UMTS, F is short for FDD LTE , I is short for NB-IoT and T is short for TDD LTE, L is short for LTE,which can be FDD LTE or TDD LTE.
Figure1 shows the position of the ZXSDR B8200 in the typical GSM/UMTS/LTE/NB-IoT multi-mode network.

Product Features
As a baseband processing unit, the ZXSDR B8200 is widely used in the ZTE series of base stations, including the indoor macro BS (ZXSDR BS8800), outdoor macro BS (ZXSDR BS8900A/BS8900B), distributed BS (ZXSDR BS8700) and outdoor compact BS (ZXSDR BS8906).The ZXSDR B8200 has the following features:
Multi-mode baseband unit
The ZXSDR B8200 supports all kinds of wireless access technologies simultaneously, including GSM, UMTS, LTE and NB-IoT, which share the common control function and transmission.It fully satisfies operators' need with the minimum hardware change.
Large capacity
To adapt to the rapid expansion of networks and the development of the multi-mode network, the latest BBU boards are released with higher processing capacity.The capacity indices of new boards surpass legacy ones, including RRC connected user number, cell number and data throughput.The increase in the board capacity improves the overall capacity of the BBU.In addition, the new boards can be used together with the legacy ones, which provide flexibility during upgrade.
Plug-in design for shelf, zero footprint, convenient deployment
ZXSDR B8200 adopts a Plug-in design with 19-inch, 2U in height and 8.75 kg (with full configuration) in weight.It can be conveniently mounted on the wall, ground, or in a 19-inch rack.
Flexible networking
ZXSDR B8200 provides GE/FE interfaces and IP networking. It supports RRU in different networking modes, such as star and chain networking to satisfy the requirements of operators in different environments and under different transmission conditions.
