The Shanghai Research Center for wireless communications recently announced that the first 4G wireless transmission system on the Chinese mainland has passed a live test, and is now at the phase of field testing and pre-commercial use. In Shanghai the world's largest 4G network field testing environment has been built.

In an on-the-spot test, the new 4G network field covers 2000 meters of the West Yan'an High Road in Shanghai. Cars drive along in a simulated road environment at a speed of 50 kilometers per hour. The data is transferred at a speed of 20 to 90 megabytes per second and the maximum upload speed is 80 megabytes per second

Shanghai Chongming County will use the 4G technology to build a wireless, wide-band network to realize complete coverage and put the technology into pre-commercial use. China has been researching and developing 4G technology for five years. This mobile communication development and research project is called the FuTURE (Future Technology for Universal Radio Environment) Project. More than 10 universities, enterprises and research organizations took part in it. According to the plan, the period of 2001 to 2003 was the key technology phase of the project; 2003 to 2006 was the phase of system demonstration and application; and 2006 to 2010 is the phase of field testing and advanced commercial use

Wei Guo, a member of the FuTRUE project group and a professor at the University of Science and Technology of China, said that "this is the largest B 3G testing system in the world, and it integrates such technologies as IPv6 Core Networking, High Definition Business of IPTV (Internet Protocol Television) and Mobile Communication Switching."

You Xiaohu, the director of the Shanghai Research Center for Wireless Communications, said that although the Chinese mainland is at the forefront of the world in 4G network coverage technology, it lags behind in short distance transmitting technology compared to developed countries. China's 4G network communication technology is currently in a research and development period, and related products will be available commercially in five years, according to the plan.
