ABSTRACT:
A method for wireless LAN communication using multiple channels is provided. An ATIM containing channel information is generated when there is data to be sent, and the ATIM is transmitted via a main channel after a predetermined period of time. When a station loses a channel reservation competition, the station generates and transmits via the main channel another ATIM containing channel information regarding another channel to be used from data transmission. The station then performs channel switching to the other channel corresponding to the channel information, transmits the data via the other channel, and switches the channel back to the main channel at the time of a subsequent beacon.
