Abstract :
The International Telecommunication Union (ITU) is in the process of developing standards for the third generation (3G) mobile cellular system, also known as IMT2000. Meanwhile, the European Telecommunications Standard Institute (ETSI) has adopted and recommended W-CDMA for voice and data, and TD-CDMA (DS) for other terrestrial services. The mobile will support up to 384 kb/s and in a non mobile environment up to 2 Mbps. As 3G cellular is moving from development into trials and implementation, it appears that there will be more than one standard. Japan and Europe are leaning towards W-CDMA and TD-CDMA, while the USA is leaning towards CDMA1. Multimedia services will be supported up to 2 Mbps
