Ultra-wideband

Summary

Ultra-wideband 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. UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precise locating, and tracking. UWB support first appeared in high-end smartphones in 2019. For a detailed list of Ultra-wideband supported mobile devices, see List of UWB-enabled mobile devices.
