ABSTRACT:
A wireless LAN base station scans frequency channels available for use in a wireless LAN, detects a beacon signal of a near-by wireless LAN base station, and thereby the number of the near-by base stations in the wireless LAN is notified. The notified number of the near-by base stations is recorded in a network table. A wireless LAN base station which should determine a radio channel in the next is determined, based on the recorded number of the near-by base stations, using a wireless LAN base station having a smaller number of the near-by base stations as the starting point of radio channel determining process, after the wireless LAN base station at the starting point determines a radio channel. By repeatedly carrying out the above-described operation, the radio channels of the whole wireless LAN are automatically determined.
