This document provides a high level description of ZTE ZXSDR R8854 S2600 (hereinafter R8854 S2600), which is the new compact 4T4R RRU (Remote Radio Unit) used in ZTE wireless total solution. R8854 S2600 provides 4-way transmission and 4-way reception to implement LTE 2*4, 4*2 or 4*4 MIMO. The RRU is based on ZTE common RRU platform, and can work in LTE single mode. Figure 1-1 Physical Appearance The document is designed to give an overview of R8854 S2600 characteristics, its key benefits, the architecture, functionality and services, as well as the system capabilities. This device is restricted to use and put into service due to the need for a spectrum license and/or the conditions attached to authorization for the use of frequencies within all European Union countries (BE/BG/CZ/DK/DE/EE/IE/EL/ES/FR/HR/IT/CY/LV/LT/ LU/HU/MT/NL/AT/PL/PT/RO/SI/SK/FI/SE/UK). 1.2 Benefits 4T4R Supported, Better Performance ZTE Confidential & Proprietary ZXSDR R8854 S2600 Product Description With four-way transmitting channels and four-way receiving channels, R8854 S2600 supports LTE 4*4 MIMO to improve coverage, data throughput and peak download speed. With 4*4 MIMO technology and CA solution, the peak downlink throughput of single user achieves higher than 1 Gbps. Faster deployment R8854 S2600 is 12L in volume and 17 kg in weight. It is portable to transport and flexible to install on the pole, tower and wall, thus reducing OPEX. High Efficiency, Lower TCO It supports dynamic adaptive PA power supply due to the output power, which reduces power consumption. The passive dissipation solution helps to save power consumption and reduce environment noise. 1.3 Application Scenarios Radio unit R8854 S2600 and baseband unit ZXSDR B8200 comprise distributed macro eNodeB. It is mostly used in LTE application with high order MIMO requirements. Typical application scenario of R8854 S2600 is shown in the following figure.

The architecture is shown in the following figure: Figure 2-3 Software Architecture Application OAM Software OSS SDR Unified Platform Linux BSP Hardware Software Hardware System The Operating and Maintenance (OAM) sub-system is the application layer. Its main functions are software downloading, configuration, management, system maintenance and measurement. ZTE Confidential & Proprietary 11 ZXSDR R8854 S2600 Product Description The Operation Support Sub-system (OSS) is the supporting layer in this entire framework. It is a hardware independent layer that provides basic functions such as scheduling, timer, and memory management, communication, sequencing control, monitoring, alarming and logging. The Board Support Package (BSP) provides device driver & initialization and supports basic functions like alarming and monitoring. It also provides the related interfaces and services to the Operating System. 2.4 Functionality R8854 S2600 is the remote radio unit of distributed base station. The signal is transmitted and received through R8854 S2600 to/from base band processing unit for further processing via standard CPRI interface. By applying the distributed system, the feeder loss will be eliminated when the radio unit is positioned close to the antenna. The coverage is enlarged with this solution. The functions of R8854 S2600 include: Supports E-UTRA operating bands of B7; Supports LTE configuration of 5/10/15/20 MHz in B7; Supports 4T4R in one box which can optimize spectrum efficiency greatly and improve network uplink performance; Support 64QAM modulation in LTE downlink and 64QAM in uplink; Supports transmit power report function for every carrier; Supports overload protection function for power amplifier; Supports transmit channel switching on/off function; Supports non-disruptive system services of BBU and other RRUs in case of software failure in R8854 S2600 connecting with them. 12 ZTE Confidential & Proprietary ZXSDR R8854 S2600 Product Description Technical Specifications 3.1 Physical Indices Table 3-1 Physical Indices Item Indices Size (Length*Width*Depth) 415 * 296 * 104 mm, 12L Weight 17 kg Color Silver gray 3.2 Performance Indices 3.2.1 Operation Frequency Band Table 3-2 Operation Frequency Band Band Operation Radio Frequency Band Rx: 2500 – 2570 MHz B7 3.2.2 Tx: 2620 – 2690 MHz Capacity Table 3-3 Capacity Mode Band RRU Capacity 2 LTE 4T4R cells, or LTE single mode B7 2 LTE 2T4R cells, or 4 LTE 2T2R cells ZTE Confidential & Proprietary 13 ZXSDR R8854 S2600 Product Description 3.2.3 Bandwidth R8854 S2600 supports all LTE bandwidth.
