The functionality of a UWB transmitter revolves around emitting billions of pulses (formerly recognized as "pulse radio") across an expansive frequency spectrum. Subsequently, a corresponding receiver deciphers these pulses into usable data by identifying a recognizable pulse sequence transmitted by the emitter. These pulses are dispatched at a rate of approximately one every two nanoseconds, contributing to UWB's capacity for real-time precision.
UWB exhibits remarkable energy efficiency, while its substantial bandwidth of 500MHz renders it well-suited for transmitting substantial amounts of data from a central device to peripheral ones, covering distances of up to around 30 feet. Nevertheless, unlike Wi-Fi, UWB does not excel in propagating through obstacles such as walls.
