Abstract: A wireless power receiving device (WPRD) comprises an RFID responder and a beacon signal oscillator to transmit an RFID response in a case where there is no electric power which is necessary for transmission of a beacon signal. A wireless power transmitting device (WPTD) operates in a wide area power transmission mode for transmitting the electric power at a wide angle toward a direction that it receives the RFID response. When the WPRD receives the electric power in a wide area power transmission mode and transmission of the beacon signal becomes possible, it transmits the beacon signal. The WPTD operates in a centralized power transmission mode for transmitting the electric power at a narrower angle toward a direction receiving the beacon signal. Also, during the centralized power transmission mode, it cyclically performs transmission and reception of the beacon signal to detect positions of the WPRD and the WPTD.
