At today's 2010 wireless communications applications (International) Symposium on the Alliance for the Promotion of China's information director, said Deng Shoupeng, 4G standard is expected in October this year, identified in the Beijing Conference, and he personally optimistic with our own intellectual property rights of TD-LTE -Advanced technical standards.
Deng Shoupeng that 4G is now the ITU said the IMT-advanced, there are two standards may evolve to 4G, one of which is LTE-advanced, is optimistic about the standard layout for many years our country has been a new generation of broadband wireless mobile communications, After carrying out the work of 3G and 4G. And, to the ITU to provide a 1000 manuscript of the world's most important creators and competitors TD.
In October 2009 in Dresden, Germany at the International Telecommunication Union ITU ITU-RWP5D Working Group 6 meeting, assembly candidate selection 4G technology. Ministry of Industry and Information Technology tour participants and submitted with independent intellectual property rights in China TD-LTE-Advanced Technology program. Finally, ITU determine LTE-Advanced and 802.16m candidate for the 4G technology of international standards.
He also said, 3G to 4G evolution from the standards to the design and development, to network construction, equipment, applications, technology and updating for 10 years, 3G to 4G broadband multimedia packet to the media, approximately 20 years. If you missed the timing of 3G development, China needs to wait for 10 to 15 years, so if you do not experience the practice of 3G 4G basically impossible to enter.
Whichever 4G What are the advantages, from the technical indicators, 4G can reach its theoretical peak downlink per 100M, up second 50M, 3G speed upgrade ratio of more than 10 times. From the technical parameters of view, to move high-definition Conference, for example, the picture is far less than 1 second delay, while the mobile network delay indicators were controlled within 100 milliseconds.
Recently constructed by China Mobile the world's first TD-LTE (4G) network of 15 demonstration in Shanghai opened. It is learned that before the end of the year, will choose three cities in China TD-LTE trial, now tentatively scheduled for Qingdao, Xiamen and Zhuhai.
