ZXSDR BS8800— Dual-mode Indoor Macro Node B

Summary

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

　　　　

Highlights

All IP Micro TCA architecture，Smoothly Evolve to Future Network: ZXSDR BS8800 adopts Micro TCA architecture, fully supports IP RAN networking, provides FE/GE interface and fully satisfies future evolution to HSPA+ and LTE.

Smooth Evolution, High Spectrum Efficiency: WCDMA and GSM can be supported simultaneously in one BS8800 which enables GSM operator smoothly evolve to WCDMA while making full use of the frequencies released by GSM (850/900/1800/1900MHz). The CAPEX and OPEX can be greatly saved.

Integrated RF Unit: 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.

High Capacity, Flexible Configuration: The baseband capacity of BS8800 supports maximum 960CE. It provides maximum 36TRX GSM or 24CS WCDMA processing capacity, and the baseband resource can be flexibly configured for local or RRU remote coverage simultaneously.

Multi-carrier Support, Smooth Expansion: RF unit of BS8800 supports up to WCDMA 4CS, or GSM 6TRX. Each sector can be configured from 1 to 4 CS of WCDMA or 1TRX to 6TRX of GSM flexibly with software upgrade only, which can fully satisfy 3G network capacity expansion requirements in the future.

High Efficiency Power Amplifier, Low Power consumption: The PA efficiency achieves 40% with Doherty + DPD Technology that independently developed by ZTE. Special design and algorithm for DPD technology is adopted to avoid patent problem. 20W, 40W and 60W power amplifier are supported, which can effectively reduce the OPEX.
