more T-SCDMA promotion JohnG globalsources.com Siemens, CATT codevelop TD-SCDMA standard GERMANY— Siemens and China Academy of Telecommunications Technology (CATT) have jointly developed a new standard for 3G mobile networks, the TD-SCDMA. Since 1998, CATT and Siemens have been jointly developing a new standard for 3G mobile networks, the time division-synchronous code-division multiple access (TD-SCDMA) technology. The first successful tests have been conducted at the joint research and development center in Beijing. Field trials of TD-SCDMA systems with mainland's mobile network operators are scheduled to start early next year, and commercial systems are expected to be available at the end of 2001. The main challenge for 3G mobile systems is to master both symmetric circuit-switched services like speech and video, as well as increasing the asymmetric packet-switched services like mobile Internet access. To meet this challenge, TD-SCDMA combines two leading technologies: designed as an advanced TDMA* system with an adaptive CDMA component operating in synchronous mode. TD-SCDMA is well suited for all 3G applications (symmetric services like voice and video, and asymmetric services like mobile Internet). Furthermore, the radio transmission principles of the system allow optimum utilization of radio spectrum allocated for 3G***. Seamless operation with GSM networks This mainland-endorsed international standard can be implemented less expensively than comparable 3G systems: due to the basic TDMA operation and the efficient utilization of radio spectrum, the system is in a perfect position for seamless operation within existing GSM infrastructure systems. This will enable mainland China's GSM operators to upgrade in a smooth and cost-efficient manner to 3G, as specifically, the costs for the overall integration and reuse of existing GSM core network infrastructure are decisive factors for the overall economy of a 3G solution such as TD-SCDMA. The cooperation of CATT and Siemens and their joint research, development and manufacturing efforts express the strong commitment and believe of both partners in TD-SCDMA. Already, the system has successfully been proposed by mainland China by the ITU, and became one of the international standards for 3G within the global family of IMT-2000 standards.
