ZXSDR R8882 Product Description 4 ZTE Confidential & Proprietary 1 Overview 1.1 Introduction ZXSDR R8882 (hereinafter R8882) is one distributed Remote Radio Unit (RRU) used in ZTE Uni-RAN total solution, with two transmitters. Based on the new generation of ZTE common RRU platform, R8882 can work in GSM, UMTS, LTE single mode or Multi-Mode. R8882 series includes R8882 2*60W, 2*40W, 2T2R and 2T4R. They have the same architecture; only differ from each other in power amplifier and physical vision. The document is designed to give an overview of the characteristics of R8882, its key benefits, the architecture, functionality and services, as well as the system capabilities. 1.2 Benefits  Wide Working Bandwidth, Less Hardware Investment To meet with the growing demands for wide working bandwidth, R8882 modules with wide working bandwidth are released. Maximum working bandwidth of R8882 is 75MHz for 1800M band and 35MHz for 900M band. For frequency spectrums become scarce, resources allocated for operators tend to be characterized with fragmentation and large span. RRUs with wide working bandwidth integrate more spectrum resources and help to decrease hardware investment. (This is the maximum bandwidth of the RF modules. Please make the actual module as the standard.) In LTE mode, R8882 can deal with 4 separate 1.4M/3M/5MHz or 2 separate 10M/15/20MHz bandwidths carriers. It benefits the operators who do not possess a continuous 20M bandwidth.  Clear and Simple Network

ZXSDR R8882 Product Description ZTE Confidential & Proprietary 5 R8882 supports GSM, UMTS, LTE or mixed technologies. It supports Multi-Mode at the same frequency band simultaneously. 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 low cost.  MIMO Capable, Better Performance R8882 supports 2T4R in one box, which optimizes spectrum efficiency greatly and improves network uplink performance. it brings better experience to customers.  High PA Efficiency, Low Power Consumption R8882’s PA adopts advanced efficiency enhancement technologies to realize high power efficiency, such as Doherty PA, DPD linear technology and MCPA technology. Power consumption can be greatly decreased with these features. 1.3 Application Scenarios R8882s and one base band unit (BBU) form a complete BTS/NodeB. It implements radio transmission, controls radio channels and communicates with the Base Station Controller (BSC/RNC). It supports indoor and outdoor applications. 2 Product Architecture 2.1 Physical Structure R8882 is the multi-carrier RF module with two transmitters. Now ZTE provides R8882 series, including R8882 2*60W, 2*40W, 2T2R and 2T4R. R8882s with different output power have the same architecture but differ in the power amplifier and physical indices.
