no. 1 example

[0043] will refer to figure 1 A wireless communication system according to the present invention is described. figure 1 It is a figure which shows a wireless LAN system.

[0044] 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.

[0045] 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...

Abstract

The invention provides a wireless communication system, a wireless communication apparatus, a wireless communication method and a recording medium. A term for interrupting communication caused by operation of a DFS function is reduced for a wireless communication apparatus having the DFS function and a wireless communication apparatus and a wireless communication system corresponding to the DFS function of the wireless communication apparatus. In the wireless communication apparatus and the wireless communication system having a frequency changing function for changing a using frequency upon detecting out-of-target electrical waves such as electrical waves of a weather radar on a specific using frequency, information about a connection destination having a different using frequency is notified upon detecting the out-of-target electrical waves, and the connection destination is changed by switching the frequency on the basis of the information about the connection destination.

Description

[0001] This application is a divisional application of a patent application with a filing date of November 16, 2006, an application number of 2006101467011, and an invention title of "wireless communication system, wireless communication device, and wireless communication method". technical field [0002] The present invention relates to a control operation between communication devices for communication between a wireless LAN (Local Area Network) access point device and a communication terminal device. More specifically, the present invention relates to a wireless communication system and a wireless communication device having a dynamic frequency selection (DFS) function, a wireless LAN system, a wireless LAN access point device, a wireless LAN terminal device, a wireless communication method, and a wireless communication program recorded computer readable recording medium. Background technique [0003] According to IEEE (Institute of Electrical and Electronics Engineers) 8...
