1 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.

1.2 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’

requirements of hybrid network deployment and long term evolution with lowest
cost.

 Lower Total Cost of Ownership (TCO)

ZXSDR R8872A’s PA adopts advanced efficiency enhancement technologies to
realize high power efficiency, such as Doherty PA, DPD linear technology and
MCPA technology. It also supports dynamic adaptive PA power supply due to the
output power. Power consumption can be greatly decreased together with these
features.

1.3 Application Scenarios

R8872A as the Remote Radio Unit and Baseband Unit (BBU) comprise distributed macro
base station BS8700. It can be used in dense urban area with high traffic. Typical
application scenarios of R8872A are shown in the following figure:
