Back to Basics III: What is UWB?
Ultra-wideband (UWB) is widely regarded as one of the most accurate indoor positioning technologies available. It transmits extremely short pulses across a wide frequency spectrum, enabling precise measurement of signal travel time between tags and anchors. Unlike technologies that infer distance from signal strength, UWB uses time-of-flight (ToF) and time-difference-of-arrival (TDoA) calculations, producing consistent sub-30-centimeter […]
