Abstract
A wireless apparatus that periodically sends notification signals, including: a determining module that determines, before sending the notification signal, whether a wireless channel is being used by a wireless device; a sending module that sends the notification signal if the wireless channel is not used throughout a first period; a receiving module; a controller that controls the receiving module to be able to receive a signal until a lapse of a second period after transmission of the notification signal; and a suspending module that suspends supply of power to the receiving module if a signal is not received in the second period and the number of wireless devices that can communicate with the apparatus is zero. If the receiving module receives a signal in the second period, the controller controls the receiving module to be able to receive a signal after a lapse of the second period.
