Texas Instruments and Xinwei Accelerate Broadband Voice and Data Coverage to Millions of Chinese Households

(Business News & Technology News, 1 Jul 2008)

Integrating Texas Instruments Inc.'s (TI)3GHz, multicore DSPs, optimized software and analog signal chain components, Beijing Xinwei Telecom Technology Co. Ltd's next generation McWiLL/SCDMA macro base stations will enable millions of Chinese households to receive voice and data traffic at exceptional speeds, while lowering the cost of deployment for the country's service providers. In addition, Xinwei can not only meet the aggressive deployment schedules leading up to the 2008 Beijing Olympics but also offer a migration path to Beyond3G, including TD-LTE.

SCDMA, and its off-shoot McWiLL (Multicarrier Wireless Information Local Loop), are optimized to deliver high-speed, bandwidth-intensive applications. SCDMA/McWiLL, which incorporates advanced technologies including smart antenna, software radio, CS-OFDMA, dynamic channel allocation, adaptive modulation, QoS/GoS, and enhanced spatial nulling technology, enables significantly larger coverage, higher data throughput, and more efficient combination of broadband and narrowband applications than its competitions.

More importantly, the McWiLL system, powered by smart antennas and dynamic channel allocation technologies, can support N=1X1 deployment and can allow an operator to deploy a large wide-area-network with one frequency band of 5MHz.

Xinwei's next generation macro base stations will deploy TI's multicore 3GHz-performing TMS320TCI6487 processor. With three cores running at 1GHz each, this wireless infrastructure baseband product enables base station manufacturers to extend their existing designs while entering into new markets, requiring small form factor applications with an exceptional scaleable, flexible solution.

Already the most widely deployed baseband processor for TD-SCDMA, Xinwei was able to capitalize on this "baseband on a chip", delivering a 15Mbps system on single carrier/sector using a small number of TCI6487's DSPs per board.
