ABSTRACT:
In a wireless LAN system having two or more master stations each connected to a wired LAN and a plurality of slave stations each connected to a terminal for wirelessly sending and receiving signals to and from the master station via a prescribed channel, each master station is provided with a table for managing the state of channel use. The master station has a LAN controller which periodically notifies the other master station of the state of use of its own channel via a notification packet. Upon receiving a notification packet sent periodically from the other master station, the LAN controller stores the state of use of the channel of the other master station, of which it has been notified by the notification packet, in the channel management table. When it becomes necessary to allocate a channel to the slave station under its supervision, the LAN controller refers to the channel management table, selects a channel that is not being used by any other master station, allocates the selected channel to the slave station and communicates with the slave station. The LAN controller stores the state of use of its own channel in the table.
