A wireless station (STA) and a method are disclosed that allow the STA to determine suitable characteristics for wireless transmissions from the STA. The STA may receive frames from a number of access points (APs), each frame including a country code indicating a country in which the corresponding AP is located, determine a popularity of each country code by polling the received country codes, determine in which country the STA is currently located based, at least in part, on the determined popularities of the country codes, and select a wireless channel and a transmit power level based, at least in part, on the determined country.
