3G technology is intended to revolutionize the capabilities in mobile communications. 3G is expected to extend the market for mobile communications much further than the scope of 1G and 2G. The vision of IMT-2000 (3G) is to provide users with the ability to communicate anywhere, at any time, with anyone. The Radio communications sector to the ITU (ITU-R) Task Group 8/1 meeting in Helsinki approved a comprehensive set of terrestrial radio interface specifications for IMT 2000. These different interfaces have been approved due to the need to meet differing evolution/migration requirements from incumbent 2G systems in individual regions.
