A set of global location signals, an SBAS (Satellite Based Augmentation System), or an ACI (ambient country identifier) signal can be used to automatically provide location awareness for a WLAN device. If one of the set of global location signals, the SBAS signal, or the ACI signal is detected, then the WLAN device can configure itself to comply with channel and power settings for the country/region having the detected signal(s). After configuration, the WLAN device can be “locked” to the country/region having the signal(s), thereby ensuring legal operation of the WLAN device even after subsequent restarts. If one of the signals 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.
