DALLAS Texas Instruments Inc. said Wednesday (April 30) that its TMS320C64x digital signal processor has been designed into a mobile communications basestations from the Information and Communication division of Siemens AG that support the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) standard.
TD-SCDMA is being developed as a third generation (3G) mobile communications standard for deployment initially in China. The Siemens 3G-based basestations are already in field trials in China and deployments with Chinese operators are expected to start at the end of 2003, TI said.
In October 2002, China's Ministry of Information Industry allocated 155 MHz of spectrum for use by TD-SCDMA. The standard features flexible up and downlink data rates up to 2-Mbit/s and coverage up to 40-kilometers and the standard is claimed to have spectral efficiency superior to other 3G standards.
The use of a programmable DSP allows basestations to be upgraded easily as standards evolve, TI said.
"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, a senior executive within Siemens mobile networks, in a statement issued by TI.
"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.
