Abstract :
The situation in China mainly boils down to a contest between two versions of code division multiple access (CDMA). One is Europe´s wideband CDMA (WCDMA), which was designed to be as compatible as possible with Europe´s hugely successful second-generation Global System for Mobile Communication (GSM). The other, CDMA2000, is preferred by US manufacturers like Motorola Inc. and Lucent Technologies, as well as Qualcomm. The picture has been complicated, however, by China´s development of an indigenous alternative, combining elements of other standards. China´s Ministry of Information Industry has been working with Siemens to develop a system it calls TD-SCDMA, for time-division synchronous code-division multiple access.
