Abstract
The first wireless communication unit configured to wirelessly communicate with a first wireless apparatus on a first wireless network.

The period determiner determines a transmission permission period during which data transmission by the first wireless apparatus is permitted. The notification unit notifies a control signal specifying the transmission permission period to the first wireless apparatus via the beacon signal. The power managing unit performs control so that power supply to the first wireless communication unit is suspended during a suspension period, the suspend period being a period except both the transmission permission period and a transmission timing period of the beacon signal within a whole period.
