TD-SCDMA
Time Division-Synchronous Code Division Multiple Access, or TD-SCDMA, is a 3G mobile telecommunications standard, being pursued in the People's Republic of China by the Chinese Academy of Telecommunications Technology (CATT), Data and Siemens AG, in an attempt not to be dependent on Western technology. This is likely primarily for practical reasons; other 3G formats require the payment of patent fees to a large number of western patent holders.
TD-SCDMA is based on spread spectrum technology which makes it unlikely that it will be able to escape completely the payment of license fees to western patent holders. The launch of a national TD-SCDMA network was initially projected by 2005 but has still not been achieved; the latest stage of "commercial trials" across eight cities was launched on April 1, 2008 and will eventually include 60,000 users.
