Overview

As wireless telecom technologies are rapidly developing and users' requirements are getting increasingly diverse, operators are obliged to shorten network upgrade period and speed up new services' deployment. While the conventional base stations and networking modes which require large investment and long period, and also take high risks are no longer to be feasible for the mobile communication trend.

Adhere to "achieving customers' value by technology innovation", ZTE launched the first SDR-based new generation base station in industry, fulfilling “all-IP multi-mode/multi-band convergence, smooth evolution and energy saving” Uni-RAN solution. The solution provides operators with the customized networking mode, completely changing the obsolete notion that network upgrade means reconstruction. It realizes GSM and UMTS convergent network, simplifying network architecture and implementing smooth evolution to LTE.

SDR serial base station's success originates from its remarkable features, as shown in the following:

• Multi-Mode Convergence: SDR-based Uni-RAN solution unifies 2G/3G hardware, NMS and networking mode; it integrates multiple networks into a "Uni network", saving costs and reducing OPEX.
• Multi-carrier & Large Capacity: SDR base station adopts MCPA technology to enable 1 RF unit to support multi-carrier with up to 6 TRXs and 4 CSs. It supports GMS and UMTS concurrently, fulfilling the flexible allocation of these carriers.
• Green & Environment-Friendly: Based on DPD+Super Doherty technology, SDR base station employs self-developed algorithm and D-PT technology to make PA efficiency industry leading, tremendously reducing energy consumption and carbon emission, cutting down OPEX. The distributed structure design features in small volume and light weight BBU and RRU, which fully utilizes existing space to implement "zero footprint" installation. Besides, no special transportation vehicle is required to install BBU and RRU, truly realizing green network.
• Smooth Evolution: MicroTCA architecture and multi-carrier equip SDR base station with high integrity and high processing capability. The all-IP design allows SDR base station to support full performance HSPA, and HSPA+ is available only by software upgrade, the peak rate reaches 28.8Mbps. For evolution to LTE, only adding LTE baseband board and upgrading software achiev over 150Mbps download rate, fully protecting the investment.
• Quality Services: Exceptional network planning and optimization tools and good after-sale platform are provided; customers' requirements focused solution offers operators premium quality network and services, maximizing network value.

Advanced architecture, good performance and high cost-effectiveness awarded ZTE SDR serial BTSs Infovision by Broadband World Forum Europe in 2008.ZTE SDR base stations have already left footprints in over 100 countries since the commercial release.By the end of June, 2010, accumulated delivery volume of ZTE SDR base station has achieved 700,000 base stations, making it become the new generation soft base station with No. 1 global delivery volume.
