Abstract:
1. A channel setting apparatus for setting at least one communication channel, the channel setting apparatus being installed in a wireless LAN terminal for transmitting information over at least one of a plurality of communication channels, comprising: a plurality of antennas used to communicate with external wireless LAN terminals; a channel controller for causing a search for a communication channel that is being used, and for determining, based on the communication channel in use obtained by the search, a condition of a surrounding radio wave environment and for controlling channel setting so that respective communication channels differ from each other; and a plurality of wireless interfaces, connected to the antennas and the channel controller, for establishing communications between the plurality of antennas and other external wireless LAN terminals, wherein the channel controller includes: wherein the channel controller: wherein the first wireless interface uses the set communication channel to interrogate all surrounding wireless LAN terminals using the set communication channel about the number of terminals connected to the set communication channel, wherein the memory stores the number of terminals connected to the set communication channel on the basis of the inquiry made by the first wireless interface, and wherein the channel selector selects from the memory a minimum communication channel whose minimum wireless LAN terminal number is smallest among the minimum wireless LAN terminal numbers of the minimum channels so as to set the selected communication channel to the first wireless interface.
