Ultra-wideband indoor positioning technology: ultra? Wide? Band? Ultra wideband. It is a wireless carrier communication technology, which can realize high-speed pathless access in dense places such as indoors. According to the plan of the Federal Council of the United States, the working frequency band of UWB is 3. 1~ 10.6GHz. Compared with the traditional narrowband system, UWB system has the advantages of strong penetration, low power consumption, good anti-multipath effect, high security and low system complexity. Most importantly, due to the different physical characteristics, UWB positioning is naturally defined as real-time, accurate and ultra-high positioning accuracy, and the positioning accuracy can reach 10cm.
