Abstract
An ultra-wideband (UWB) anchor using a UWB ON/OFF operation method to minimize power consumption. 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 to transmit a reception failure when failing to receive the UWB signal from the UWB tag, and a controller to receive the reception failure from the transceiver and to end a ranging session when a cumulative sum of ranging failures for each ranging block reaches a maximum number of failed ranging round attempts.
