Overview
1.1
Introduction
This document provides a high level description of ZTE ZXSDR R8872A (hereinafter
referred to as R8872A), which is the latest compact RRU (Remote Radio Unit) used in
ZTE wireless communication solution. Based on ZTE common innovative SDR platform,
R8872A can work in GSM, UMTS, or LTE single mode or multi-mode at the same
frequency band. The volume of R8872A is 20L, and its weight is 23Kg.
The document is designed to give an overview of the characteristics of R8872A, its key
benefits, the architecture, functionality and services. The document also describes the
system capabilities.

Benefits
High performance
R8872A has 2*80W of high TOC output power. With high output power, it supports
large capacity which can be used in large site in dense urban with high traffic.
R8872A is designed with wide bandwidth to meet with the growing demands for
wide working bandwidth. E.g., R8872A supports 75MHz of IBW (instantaneous
bandwidth) in band3 1800MHz frequency band. RRUs with full working bandwidth
integrate more spectrum resources and help to decrease hardware investment
exponentially.
SDR 2T4R design to ensure one clear and simple network
R8872A supports GSM, UMTS, LTE or mixed technologies. Design of 2T4R
channels ensures the smooth evolution of the system from GSM/UMTS to LTE 2*2
MIMO. Instead of running hardware on independent platforms for each technology,
operators can implement various wireless technologies through software
configuration on the same hardware platform. It fully satisfies operators
