[0042] A wireless communication system according to the present invention will be described with reference to FIG. 1 . FIG. 1 is a diagram showing a wireless LAN system.
[0043] The wireless LAN system 2 is an example of a wireless communication system according to the present invention, and includes a plurality of wireless LAN access point devices (hereinafter, simply referred to as access points) APx having a DFS function as a first communication device, and as a second communication device. A plurality of wireless LAN terminal devices (hereinafter, simply referred to as "LAN terminals") CLx of communication devices or clients of the access point APx.
[0044] In the access point APx and the LAN terminal CLx, the reference x represents 1, 2, . . . , N. In this case, the access point APx includes the access points AP1, AP2, . . . , APN, and the LAN terminal CLx includes CL1, CL2, . . . , CLN. Furthermore, the access points AP1, AP2, . . . , APN are connected by LAN cables,...

[0073] Next, a wireless communication device according to the present invention will be described with reference to FIG. 5 . FIG. 5 is a diagram showing a configuration example of an access point according to a second embodiment of the present invention. In FIG. 5 , the same parts as those in FIGS. 1 and 2 are assigned the same reference numerals.
[0074] The access point AP1 (or AP2, . . . , APN) is used for the first communication device in the wireless LAN system 2 . At the access point AP1, the wireless communication unit 10 is a functional unit for performing wireless communication with the LAN terminals CL1, CL2, ..., CLN, and includes a baseband processor (processing) 100 as a communication control unit, as a wireless unit ( RF) transceiver 102, and a power amplifier unit (Power Amp) 104. Furthermore, a wireless communication unit 10 is connected to the antenna 6 . Furthermore, the wireless communication unit 10 is controlled by a CPU (Central Processing Unit) 106 i...

[0109] Next, a wireless communication method according to the present invention will be described with reference to FIG. 10 . Fig. 10 is a flowchart showing a processing sequence between an access point and a LAN terminal and cooperative processing between them according to the third embodiment.
[0110] These processes use the wireless LAN system 2 (see FIG. 1 ), the access point APx (see FIGS. 2 and 5 ), and the LAN terminal CLx (see FIGS. 4 and 6 ).
[0111] According to the third embodiment, an access point APx exists in the same network 4, acquires information related to another access point APx capable of roaming, and executes a function for converting the representation to The notification of this information is sent to the processing of the LAN terminal CLx.
[0112] The access point AP1 detects radio waves of the weather radar on the channel being used (step S51).
[0113] At the timing for detecting weather radar waves, a Deauth packet is transmitted from the acces...
