WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION DEVICE
First Claim
1. A wireless communication system that shares a frequency band with another wireless system, said wireless communication system comprising:
- wireless communication devices of a plurality of master stations that perform communications using different frequency channels; and
a wireless communication device of a slave station that connects with either one of the wireless communication devices of said plurality of master stations, and performs wireless communications, whereinwhen detecting a wireless signal of said other wireless system and stopping communications which has been being performed till then via a frequency channel, the wireless communication device of said master station commands the wireless communication device of said slave station which has been performing wireless communications by using this frequency channel, to switch its connection destination to the wireless communication device of another master station that performs communications using a different frequency channel, and the wireless communication device of said slave station switches its connection destination to the wireless communication device of said other master station according to the command from the wireless communication device of said master station.

Abstract
A wireless communication system includes APs 1 and 2 that perform communications using different frequency channels, and slave units 3 to 5 that connect with either one of the APs 1 and 2 to perform wireless communications. When detecting a radar wave which is a wireless signal of another wireless system, and stopping the communications which have been performed till then via a frequency channel, the AP1 commands the slave units 3 to 5 that have been performing wireless communications by using this frequency channel to switch their connection destinations to the AP 2 that performs communications using a different frequency channel, and the slave units 3 to 5 switch their connection destinations to the AP 2 according to the command from the AP 1.

8. A wireless communication device with which a wireless communication system that shares a frequency band with another wireless system is provided, said wireless communication device comprising:
-
a wireless unit that communicates with a wireless communication device of a slave station; a controller that, when said wireless unit detects a wireless signal of said other wireless system and stops communications which has been being performed till then via a frequency channel, commands the wireless communication device of said slave station which has been performing wireless communications by using this frequency channel to switch its connection destination to a wireless communication device of another master station that performs communications using a different frequency channel via said wireless unit.
