|First public demonstration of TD-SCDMA by Siemens and CATT|

[The 3GPP acknowledges TD-SCDMA as a global standard for UMTS.]
TD-SCDMA is enjoying worldwide acceptance within the framework of international standardization. In a recent decision the "Third Generation Partnership Project" (3GPP), an umbrella organization of all the major international standardization bodies for third generation mobile radio (3G), acknowledged TD-SCDMA (Time Division Synchronous Code Division Multiple Access) as a global standard for UMTS (Universal Mobile Telecommunications System). Furthermore, the Siemens Information and Communication Mobile Group (IC Mobile) and CATT (China Academy of Telecommunications Technology) conducted the world's first public demonstration of wireless transmission via a TD-SCDMA air interface in front of Chinese media and mobile network operators.
TD-SCDMA is gaining wide acceptance on the international standardization front. 3GPP's recent decision puts the technology, jointly developed by Siemens IC Mobile and CATT and also known as "TDD Low Chip Rate", on an equal footing with the recognized "High Chip Rate" transmission methods FDD (Frequency Division Duplex or Wideband-CDMA) and TDD (Time Division Duplex) within UMTS. This worldwide recognition will guarantee that from the technical point of view the UMTS transmission methods FDD, TDD and TD-SCDMA can intercommunicate seamlessly with each other and with the current GSM (Global System for Mobile Communications) standard.
The first public demonstration of TD-SCDMA with wireless data transmission took place in the joint research and development center in Beijing and was realized between two PCs, connected via a wireless link with a mobile radio base station and a prototype terminal device. Around the middle of the year, the test network will enable mobile network operators in China to run the first trials with TD-SCDMA. Network solutions for commercial use are set for launch at the beginning of 2002.
