ABSTRACT:
An ambient country identifier (ACI) signal can be used to automatically provide location awareness for a WLAN device. If an ACI signal is detected, then the WLAN device can configure itself to comply with channel and power settings for the country having the detected ACI signal. After detection of the ACI signal, the WLAN device can be “locked” to the country having that ACI signal, thereby ensuring legal operation of the WLAN device even after subsequent restarts. If an ACI signal is not detected, then the WLAN device can be configured in a default mode, e.g. an “open mode” in which end users can configure the WLAN device by entering a country of operation or a “common mode” in which the channel and transmit power settings meet global spectrum usage requirements.
