US : Catapult Communications announced support for TD-SCDMA technology. TD-SCDMA has gained significant support in China where the Ministry of Information Industry has made it mandatory for all six of the major Chinese telecommunications operators to test TD-SCDMA in 2004.
"China is the world's largest cellular market and being able to provide TD-SCDMA test solutions is key to Catapult's future success in that market," said Dave Mayfield ( inset ), Catapult President and COO. "Our customers are now able to test 3G networks and equipment based on all three of the major 3G technologies: W-CDMA (UMTS), cdma2000, and TD-SCDMA." TD-SCDMA (Time Division -- Synchronous Code Division Multiple Access) is a 3G radio access technology developed by the China Academy of Telecommunications Technology and Siemens AG. By using TDMA/TDD (Time Division Duplex) technology with an adaptive CDMA component, TD-SCDMA employs advanced technologies such as Smart Antenna and Joint Detection to provide
better bandwidth utilization.
