ABSTRACT:
Proposed is a technique for implementing data communication and distance measurement even in a case where data communication and distance measurement share the physical layer. A wireless communication apparatus includes a radio unit and a distance measuring unit. The radio unit performs communication using a frame that includes at least a data period for transferring data and a beacon period for transmitting a beacon. The distance measuring unit utilizes the beacon period to measure the distance from the wireless communication apparatus to a target object whose distance is to be measured.
