Texas Instruments and Xinwei accelerate broadband voice and data coverage to millions of Chinese households
Xinwei leverages TI’s multicore DSPs in McWiLL/SCDMA base stations
According to ABI Research analyst Serene Fong, there will be approximately 103 million wireless broadband households in China by 2010, a 14 percent CAGR growth from 2007. Many of these households clearly benefit from these broadband wireless advancements. SCDMA, and its off-shoot McWiLL (Multicarrier Wireless Information Local Loop), are optimized to deliver high-speed, bandwidth-intensive applications. SCDMA/McWiLL incorporates advanced technologies including smart antenna, software radio, CS-OFDMA, dynamic channel allocation, adaptive modulation, QoS/GoS, and enhanced spatial nulling technology. Such state of the art technologies, integrated in a synergetic way, enable the McWiLL system to have significantly larger coverage, higher data throughput, and more efficient combination of broadband and narrowband applications than its competitions. More importantly, further surpassing its popular alternatives, 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. The superb performance comes from sophisticated implementation of the aforementioned advanced technologies, requiring very high performance processing while maintaining a low power budget.
"As a leading provider of base station technology, Xinwei looks not only at today's needs of service providers and consumers, but future needs as well," said Mr. Zhiyun Liu, vice president of Xinwei. "TI's complete signal chain solution - including DSPs, software and analog - enables Xinwei to deliver a family of base stations with additional features and capacity while reducing the overall system cost."
Xinwei's next generation macro base stations will deploy TI's multicore 3GHz-performing TMS320TCI6487 processor. With three cores running at 1 GHz 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.
"We are very pleased to enable Xinwei to deliver this exceptional technology to the people of China," said Eldon Teng, director of Asia sales and marketing with Texas Instruments. "As a committed participant in China's communications infrastructure growth, it is an honor to provide our customers with the best DSP technology available."
Complete DSP Baseband Solution Speeds Time to Market
Building on TI's current WiMAX leadership, the TCI6487 is an excellent solution that meets the unique needs of today's emerging OFDMA requirements and tomorrow's LTE demands. The single-chip DSP solution works in conjunction with TI's optimized software library, complete analog front end and key products from third parties. Now, TI's customers can quickly get to market with advanced products for current requirements and have the ability to shrink as future smaller form factor requirements demand. A complete 10-MHz, 2-antenna, 3-sector solution can easily be implemented, improving overall cost and power per channel.
TI offers the industry's broadest wireless infrastructure product portfolio, spanning the complete signal chain. Supporting analog products include digital up/down converters, high speed data converters, RF products, timing, backplane interface and standard logic components. Highlighting the company's leadership in power management, TI has developed a non-isolated DC/DC power module with extremely fast response and high performance. It is the first power management device to meet core voltage tolerance requirements of the TCI6487.
