Abstract
An ultra-wideband (UWB) anchor using an UWB ON/OFF operation method to minimize degradation of ranging performance. The UWB anchor includes: a power supply to supply power to the UWB anchor; a transceiver to transmit/receive a UWB signal to and from a UWB tag for performing ranging; and a controller to end a ranging session when a cumulative sum of ranging failures for a specific time unit reaches a maximum number of failed ranging round attempts, and to control the power supply and the transceiver to re-enter a UWB signal-reception standby (or UWB ON) mode when a condition is satisfied.
