What is the development history of UWB?

Ultra-wideband (UWB) technology first appeared in American military field. In April, 2002, the Federal Communications Commission (FCC) of the United States lifted the civil license restrictions of UWB technology, and since then, UWB technology has been rapidly popularized and developed. At the same time, FCC allocated 3.1-10.6 GHz * * * 7.5 GHz bandwidth for UWB. The development of China's ultra-wideband industry started late, but it is highly valued by the party and the country. At the beginning of September, 20065438, "Ultra-wideband wireless communication technology and its * * * storage and compatibility technology" was taken as the research content of wireless communication technology and innovative technology for the first time in the "Tenth Five-Year Plan" national 863 communication technology research project, which shows that the state attaches importance to the development of ultra-wideband. As the mission of the Institute, Zhengzhou Li Anrui Electronics was founded on 20 10, and is committed to building the first brand of indoor wireless precise positioning.
