BEIJING -- Nortel Networks and Datang Mobile opened a laboratory in Beijing today in a move to explore the commercialization of the Time Division – Synchronous Code Division Multiple Access (TD-SCDMA) technology in China.

TD-SCDMA is a Chinese third generation (3G) wireless technology combining the advantages of CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications). TD-SCDMA combines the unique spectrum efficiency of CDMA with the possibility of asymmetric data-transfer provided by the Time Division Multiple Access (TDMA) frame structure of GSM. In 2000, TD-SCDMA was adopted by the International Telecommunication Union (ITU) for the IMT-2000 family of 3G standards. It was also adopted by the Third Generation Partnership Project (3GPP).

Nortel Networks has provided the core network and Datang Mobile the access network. The laboratory plans to conduct tests in the areas of interoperability, network performance and system functions based on TD-SCDMA.

"The laboratory is one of the most advanced in China focusing on commercialization of TD-SCDMA," said Robert Mao, president and chief executive officer, Greater China, Nortel Networks. "It demonstrates our capability and commitment in developing this Chinese 3G standard. The laboratory will promote further acceptance of the standard and enhance Nortel Networks leadership position in providing 3G solutions in China."
