For the position of the ZXSDR R8862A (RRU) in radio access networks, see Figure 1-2. Figure 1-2 ZXSDR R8862A Position in Radio Access Networks The ZXSDR R8862A provides the following functions: 1-2 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential Chapter 1 Product Overview Support the configuration of 1.4 MHz/3 MHz/5 MHz/10 MHz/15 MHz/20 MHz scalable bandwidth; Band Supported: 850 MHz/1800 MHz/2100 MHz/2600 MHz; Support 2T4R (S8500/S1800/S2100/S2600) in one box which can optimize spectrum efficiency greatly and improve network uplink performance; Support 64QAM modulation in both downlink and uplink; Support transmit power report function for every carrier; Support overload protection function for power amplifier; Support transmit channel switching on/off function; Software failure will not affect the running of BBU and other ones which are connected to it. 1.3 Features Multi-Mode RRU ZXSDR R8862A is fully software defined. GSM/UMTS/CDMA RRU based on ZXSDR R8862A platform can be upgraded to LTE RRU at the same frequency band through software update only. It supports multi-mode at the same frequency band simultaneously. Therefore, it fully satisfies operators’ requirements of hybrid network deployment and long term evolution with lowest cost. Wider Bandwidth ZXSDR R8862A is based on Multi-Carrier Power Amplifier (MCPA) technology. MIMO Supported, Better Performance ZXSDR R8862A is based on new compacted RRU platform and high efficiency Power Amplifier technology. As a result, it brings better customer experience, zero footprint and easy deployment. It is portable to transport and flexible to install on the pole, tower and wall, thus reducing OPEX. Higher Efficiency, Lower TCO ZXSDR 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 ZXSDR R8862A supports integrated Lightning protection unit (PIB), and the protection level is 20 kA. 1-3 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential ZXSDR R8862A Product Description This page intentionally left blank. 1-4 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential Chapter 2 System Architecture Table of Contents Hardware Architecture................................................................................................2-1 Software Architecture .................................................................................................2-2 2.1 Hardware Architecture The ZXSDR R8862A consists of a power supply, a transceiver, a power amplifier and a duplexer.

Power Amplifier This module, integrated with a low-noise amplifier, amplifies downlink RF signals and sends the amplified signals to the duplexer. Duplexer This module combines a filter and two duplexers implementing Rx diversity. 2-1 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential ZXSDR R8862A Product Description 2.2 Software Architecture For the ZXSDR R8862A software architecture, see Figure 2-2. Figure 2-2 ZXSDR R8862A Software Architecture A Linux operating system runs on the hardware platform of the ZXSDR R8862A.The BSP (Board Support Package) contains a suite of software closely related to boards, which support the running of the RTOS (Realtime Operating System) on the boards. The operation support layer of the software system provides the following functions: The OSS (Operation Support Sub-system) serves as the support layer of the entire software architecture. It provides a hardware-irrelevant platform on which the software runs to provide basic functions, such as scheduling, timing, memory management, inter-module communication, queue control, monitoring, alarm management, and log management. The SCS (System Control Sub-system) controls the power supply and active/standby switchover. OAM (Operating and Maintenance) supports configuration management, alarm management, and performance measurement. The DBS (Data Base Sub-system) stores and manages data in the system. The BRS (Barrier Sub-system) processes protocols for the system. The BRACS (Barrier Access Control Sub-system) controls access to the bearer layer. 2-2 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential Chapter 3 Operation and Maintenance Table of Contents Operation and Maintenance Modes............................................................................3-1 Operation and Maintenance Functions .......................................................................3-2 3.1 Operation and Maintenance Modes Remote Operation and Maintenance The ZTE NetNumen U31 Unified Element Management System (EMS) is used to operate and maintain the ZXSDR R8862A remotely. The EMS connects to the BBU to which the ZXSDR R8862A is connected through a CPRI interface, see Figure 3-1. Figure 3-1 Remote Operation and Maintenance In remote operation and maintenance mode, the EMS connects to an NE through TCP/IP. The EMS can be used to operate and maintain multiple base stations. Local Operation and Maintenance In local operation and maintenance mode, an LMT (PC) is connected to the ZXSDR R8862A with an Ethernet cable, see Figure 3-2. 3-1 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential ZXSDR R8862A Product Description Figure 3-2 Local Operation and Maintenance The LMT is used for local operation and maintenance of an individual base station. It supports basic operations on the base station, such as power query, power increase and decrease, and calibration. 3.2 Operation and Maintenance Functions The NetNumen U31 Unified Element Management System (EMS) provides a GUI that displays information of all NEs in the entire network on a topology map. A user can view performance data, alarm information, and configuration data of a specific NE, and operate and maintain multiple NEs of the same type on the topology map. NetNumen U31 has the following operation and maintenance functions: Configuration management The configuration management supports dynamic and static configurations of base stations, such as the addition, query, deletion, modification, and data consistency check of physical and radio resources. Security management The security management ensures that only authorized users can perform permitted operations on base stations. Performance management The performance management supports performance analysis, calling trace, and signaling trace. Version management The version management allows users to view hardware and software versions in base stations and download latest versions for software upgrade. Fault management The fault management includes alarm management and diagnostic tests. By using the fault management functions, maintenance personnel can monitor the operational statuses of base stations and collect the information of board and link faults in real time for fault analysis and equipment maintenance. 3-2 SJ-20130814154658-001|2014-08-20 (R1.4) ZTE Proprietary and Confidential Chapter 4 Technical Indices Table of Contents Physical Indices .........................................................................................................4-1 Environment Indices...................................................................................................4-1 Power Indices.............................................................................................................4-2 Performance Indices ..................................................................................................4-2 Reliability Indices .......................................................................................................4-3 Electromagnetic Compatibility Indices ........................................................................4-3 4.1 Physical Indices For the ZXSDR R8862A physical indices, refer to Table 4-1.
