Recently, China’s first ultra wideband audio/video transmission system conforming the Chinese Spectrum Planning and Standards has been successfully developed in the Radio Frequency Integrated Circuit Department (Department 11) of Institute of Microelectronics of Chinese Academy of Sciences (IMECAS) after more than two years of persistent efforts jointly with Institute for Infocomm Research of Singapore, with the support of the International Cooperation Program of the Ministry of Science and Technology of China.
The ultra wideband wireless audio/video transmission system employs 6-9 GHz frequency range according to the Chinese Frequency Spectrum Planning, which includes a radio frequency transceiver front end module, a digital baseband transceiver module, and a video encoding and decoding module, and has achieved the wireless transmission of 1080p high definition video with clear and smooth video images. Currently, this project has formally passed the inspection and acceptance procedure by the Ministry of Science and Technology, and has been recommended to be included in the Collection of Achievements of the International Scientific and Technological Cooperation Programs during the “Eleventh Five-Year Plan”.
Ultra wideband is a new type of short-distance and high-speed wireless communication technology, and its transmission speed can reach above 480 Mbps. In December 2008, the Ministry of Industry and Information Technology issued China’s Ultra Wideband Spectrum Planning, to promote wide applications of the ultra wideband technology in China. A series of efforts have been carried out by IMECAS aiming at Chinas’ Ultra Wideband Spectrum Planning and Standards, and some relevant achievements have been made relating the ultra wideband standards, chips, systems and industrialization thereof, and such achievements not only take the preemptive opportunities in domestic market for chips with proprietary IP rights in the ultra wideband field, but also provide an important platform for proprietary system innovations.
