TI Technology Deployed In TD-SCDMA

Supporting China´s rapidly growing wireless market, Texas Instruments Incorporated (TI) announced shipments of its high performance TMS320C64x TM class DSPs into Siemens Information and Communication Mobile Group´s (Siemens mobile) Node B Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) basestations. The 3G-based basestations are already in field trials in China and deployments with Chinese operators are expected to start at the end of 2003.

Market forecasts peg China as one of the fastest growing wireless markets in the world, with over 200 million mobile phone users today. Siemens and the China Academy of Telecommunications Technology (CATT) jointly developed the TD-SCDMA standard to address the growing need for wide spectrum bandwidth allocation.

In October of 2002, the Ministry of Information allocated 155 Mhz of spectrum for use by TD-SCDMA as a newly adopted standard for third generation (3G) mobile networks in China. The standard features flexible up and downlink data rates peaking at 2Mbps, coverage up to 40km, and optimal spectral efficiency through use of TDMA and synchronous CDMA technology. TD-SCDMA also preserves carrier's investment in previous infrastructure by reusing the existing GSM core network, the most pervasive mobile network technology in China today.

Utilizing the TMS320C6416 DSPs, the industry's highest performance DSP designed for digital baseband processing, TI helps to reduce costs for carriers by offering a smooth migration from 2G to 3G. This programmable DSP platform allows basestations to be upgraded easily as standards change and evolve further, and demonstrates TI's leadership in the wireless infrastructure market, allowing customers like Siemens to build reliable and cost-effective basestations.

"By using a software approach based on the TMS320C6416 together with TI tools and service we were able to get to market fast, reduce cost and have a key differentiator for our customers in the Chinese market," said Klaus Maler, president, business segment TD-SCDMA within Siemens mobile networks.

"Siemens and TI strongly believe in TD-SCDMA and collaboration on this basestation underlines this belief and our partnership. China is the world's biggest mobile telecom market and continues to grow faster than all other markets," said Dave Shepard, general manager of TI's wireless infrastructure products group.

TI strongly believes in the momentum of the Chinese market and has jointly invested with other major mobile telecom players in the company COMMIT whose aim is to provide TD-SCDMA handsets for the Chinese market.
