Patent abstract
A wireless communication system includes plural wireless communication apparatuses which form an ad-hoc network. In the system, an operating state of each superframe of each wireless communication apparatus is determined from three operating states: an active state in which beacon signal transmission/reception and data transmission/reception are performed as necessary; a sleep state in which beacon signal transmission/reception and data transmission/reception are not performed; and a pre-receive state in which a beacon signal is received and afterward beacon signal transmission and data transmission are not performed.
