Abstract:
A method of selecting a cellular network entails detecting a Wi-Fi signal, obtaining a country code from the Wi-Fi signal, prioritizing cellular network frequency bands based on the country code to define a band priority, and selecting a cellular network based on the band priority. The country code may be an IEEE 802.11d Country Code Information Element.
