ZXSDR BS8800—Dual-mode Indoor Macro Base Station

　　Overview

　　ZXSDR BS8800, a new generation dual-mode indoor macro base station of SDR series products, can offer various coverage solutions for dense urban, urban, suburban, highway, and indoor scenarios. ZXSDR BS8800 consists of two main parts: Baseband unit and RF unit. It develops a new solution for 2G/3G mixed networking and network evolution, so that the network construction cost is greatly decreased. The figure is below:

　　Highlights

　　• ZXSDR BS8800 adopts MicroTCA architecture, fully supports IP RAN networking, provides FE/GE interface and fully satisfies future evolution to Enhanced EDGE, HSPA+ and LTE.

　　• GSM and UMTS can be supported simultaneously in one BS8800 which enables GSM operator smoothly evolve to UMTS while making full use of the frequencies released by GSM.

　　• RF unit is integrated with transceiver unit, duplex filters, power amplifier module, and RPWDC. This design reduces boards’ quantity, save costs, decreases communication requirements and interfaces between boards, and greatly improves the overall reliability.

　　• The PA efficiency achieves 45% with DPD + Super Doherty technology that independently developed by ZTE.

　　Benefits

　　• All IP Micro TCA architecture，smoothly evolve to future Network.

　　• Smooth evolution, high spectrum efficiency, the CAPEX and OPEX can be greatly saved.

　　• High efficiency power amplifier can effectively reduce the OPEX.
