Yes you read it right! Its 4G

China has launched the world's first fourth-generation (4G) mobile communication system in Shanghai. The 4G system provides speedy wireless transmission of data and images; with a speed of up to 100 MBPS, which is many times faster than the technology that is presently being used.

The research on B3G/4G (beyond 3G) was initiated in 2001 in China under the aegis of 'Future Technology for Universal Radio Environment'. The project involves about 10 leading domestic institutions, and has successfully obtained over 200 patents till now. China expects to conduct 4G technology field tests and begin trials for commercial use somewhere between 2006 and 2010.
