Abstract: A wireless communication system using wireless LAN channels for wireless communication is disclosed, comprising: master access point, slave access points, and computing unit. First, the master access point creates a collision record table and a usage time record table. After that, the master access point updates the collision record table and usage time record table based on the usage information, and transmits the collision record table and usage time record table to the slave access points. The computing unit generates the channel collision probability through the number of collisions, and calculates the usage weight of the dynamic frequency selection channel through the channel collision probability. Finally, the wireless communication system automatically selects the wireless LAN channels of the master access point and the slave access points according to the usage weight and usage time record table. As such, the wireless communication system has high efficiency and low delay.
