摘要： A wireless communication device is quickly connectable to an access point of a destination service area without wasting power when the wireless communication device moves from a service area to a different one. When a state change detector of the wireless communication device detects that the received radio field intensity of the radio wave from the connected access point lowers to a threshold or less, a service area information acquirer acquires information on the service area where the wireless communication device is present and information on a neighboring service area. A profile information acquirer acquires profile information corresponding to the service area information. A priority order setter sets the order of priority to the acquired profile information in such a way that the access point of a neighboring service area neighboring to the service area formed by the connected access point is precedingly connected. According to the profile information to which orders of priority are set, a request for connection to the access point is made.

摘要： This electrical power-receiving apparatus makes it possible to suppress a decline in power supply efficiency in a variety of different circumstances while avoiding an increase in circuit scale. This apparatus comprises an impedance control unit (307) for sequentially switching through any one of a plurality of charging devices in a charging device group (310), as candidate charging devices for a supply destination to which electrical power is to be supplied. The impedance control unit (307) also selects from the candidates a charging device to which electrical power is actually supplied, on the basis of the difference between the impedance of the charging device group (310) for each candidate and the impedance of an electrical power receiving antenna unit (301), and causes electrical power to be supplied to the selected charging device.
