Ultra-wideband

Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum.^[1] UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precise locating,^[2] and tracking.^[3]^[4] UWB support started to appear in high-end smartphones in 2019.
