& Proprietary ZXSDR R8862A Product Description 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. ZTE Confidential & Proprietary ZXSDR R8862A Product Description Figure 1-1 LTE Network Architecture eNodeB – Distributed SDR S1 X2 eNodeB – Integrated SDR X2 MME / S-GW S1 S1 X2 eNodeB – Distributed SDR MME / S-GW S1 EUTRA EPC EPS 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. Faster deployment ZTE Confidential & Proprietary ZXSDR R8862A Product Description R8862A is 12L in volume and 15Kg in weight. It is portable to transport and flexible to install on the pole, tower and wall, thus reducing OPEX. Higher Efficiency, Lower TCO R8862A’s PA efficiency can reach up to 45% (The PA efficiency is different based on different working frequency bands); It supports dynamic adaptive PA power supply due to the output power, which reduces power consumption. It is passive thermal dissipation designed, so it is power saving and less noisy. Integrated lightning protection unit R8862A supports integrated Lightning protection unit (PIB), and the protection level is 20 KA. 1.4 Application Scenarios R8862A as the Remote Radio Unit (RRU) and Baseband Unit (BBU) comprise distributed macro eNodeB BS8700. Typical application scenarios of BS8700 are shown in the following figure: Figure 1-2 BS8700 Application Scenarios ZTE Confidential & Proprietary ZXSDR R8862A Product Description Product Architecture 2.1 Physical Appearance The physical appearances of R8862A are shown in the following figure.
