Abstract
A wireless channel determination/selection method for use in an access point device configuring a wireless LAN system with a terminal device is disclosed. The method includes: a first step of selecting sequentially a wireless channel available for use, detecting a reception signal level for each of the wireless channels, determining whether a wireless LAN signal is included, and receiving data transmission/reception state notice information that is inserted in a beacon frame provided by another access point device to indicate a state of data transmission/reception at the another access point device; a second step of detecting, from the received data transmission/reception state notice information, a data transmission/reception level at the another access point device for each of the wireless channels; and a third step of determining and selecting any of the wireless channels considered optimum for communications.
