1 Overview

1.1 Introduction

This document provides a high level description of ZTE ZXSDR R8862A (hereinafter
R8862A), which is one new compact distributed RRU (Remote Radio Unit) used in ZTE
wireless total solution. The RRU is based on common ZTE compacted RRU platform,
and can work in GSM, CDMA, UMTS or LTE single mode or Multi-Mode at the same
frequency band.

The document is designed to give an overview of the characteristics of R8862A, the key
benefits, architecture, functionality and services. The document also describes the
system capabilities.

1.2 LTE Network Architecture

LTE is a market driven technology, which offers higher data rate (150Mbps downlink and
75Mbps uplink for each cell @ 20MHz, MIMO 2*2) with low latency and short setup delay
that aim to improve end-user throughput, increase cell capacity, reduce user plane
latency, and consequently offer superior user experience with full mobility. The flat, all
IP-based network architecture and improved spectrum efficiency (2 to 4 times higher
compared with HSPA Release 6) have laid the foundation for low cost per bit delivery
and overall CAPEX/OPEX reduction.

Unlike other technologies like HSPA, LTE is contained within a new Packet Core
architecture called EPC (Evolved Packet Core) network architecture. Technically, 3GPP
specifies the EPC to support the E-UTRAN. TCP/IP protocols are adopted in EPC, so
LTE can support all IP-based services including voice, on-line gaming, IPTV and
message with end-to-end QoS (Quality of Service). The EPC network architecture can
improve the connection and hand-over to other fixed-line and wireless access
technologies, which enables operator to deliver a seamless mobility experience.

Figure 1-1 LTE Network Architecture

To achieve all the targets mentioned herein, LTE PHY (Physical Layer) employs
advanced technologies including Orthogonal Frequency Division Multiple Access
(OFDMA) and Multiple-Input and Multiple-Output (MIMO) data transmission. Furthermore,
the LTE PHY deploys the OFDMA for the downlink and Single Carrier Frequency
Division Multiple Access (SC-FDMA) for the uplink. These technologies will further
minimize the LTE system and UE complexities while allowing flexible spectrum
deployment in the existing or new frequency spectrum.

1.3 Benefits

 2*4 MIMO Capability, Better Performance

R8862A is based on new compacted RRU platform and high efficiency Power
Amplifier technology. With two transmitting channels and four receiving channels, it
supports 2*4 MIMO to improve coverage, data throughput and peak download
speed.
