What Is Ultra-wideband (UWB) Wireless Communication?

UWB is the abbreviation for Ultra-wideband. UWB wireless communication is wireless communication that uses the ultra-wideband frequency bandwidth. Its main feature is that it enables high-precision positioning. UWB wireless communication has spread to consumer equipment in recent years. For example, UWB wireless communication is being equipped to smartphones to prevent loss and for other purposes and is being equipped to smart keys of luxury cars. It is expected that UWB wireless communication will spread to many fields in the future. We explain here about the features, history, uses, and other elements of this UWB wireless communication.
