Wireless network having IEEE802.11h-incompliant terminal wireless device communicating with IEEE802.11h-compliant base wireless device
First Claim
1. A wireless device which has a terminal function compliant with IEEE802.11 standard but incompliant with IEEE802.11h standard, the wireless device being included in a wireless network formed by a wireless device having a base station function compliant with IEEE802.11h standard, the terminal wireless device comprising:
- a probe request transmission circuit for transmitting a probe request to the base station wireless device, the probe request being used for confirming whether or not the base station wireless device and the incompliant terminal wireless device of the same wireless network exist in the same channel; and
a base station presence confirmation circuit for receiving a probe response which is transmitted from the base station wireless device in response to the probe request transmitted by the probe request transmission circuit, thereby confirming the presence of the base station wireless device.

Abstract
In a wireless network structure which includes a wireless LAN device having a base station function (host device) which is compliant with IEEE802.11h and at least one wireless LAN device having a terminal function (slave device) which is not compliant with IEEE802.11h, the incompliant terminal transmits a probe request to the base station for confirming the presence of the base station. When the base station has dynamically switched its channel (frequency), a probe response is not returned from the base station to the terminal. Thus, the incompliant terminal transmits a probe request through a different channel in order to confirm the presence of the base station. The incompliant terminal repeats the above channel search process till the base station is found.
