A method, comprising, at a first wireless device (102; 206) lacking internet-access capability and lacking capability to determine its own geographic location: interacting (108; 1102) with a second wireless device (106; 208) having internet-access capability and having capability to determine its own geographic location, to cause the second wireless device to obtain authorization to use a set of one or more radio white space frequencies at the geographic location of the second wireless device in accordance with one or more constraints; obtaining (120; 1104) authorization information including the constraints from the second wireless device; and, utilizing the authorized one or more radio white space frequencies to communicate with a third wireless device that is not the second wireless device, independently from the second wireless device that obtained the authorization; taking steps to ensure that the utilization complies with the constraints, wherein the one or more constraints include a distance constraint, comprising: determining a relative distance of the first wireless device from the second wireless device based upon the success or failure of communications with the second wireless device at a given frequency and power; and based on the determined relative distance, determining a transmission power for the first wireless device to transmit on the authorized one or more radio white space frequencies for which the maximum transmission distance from the authorized geographic location of the second wireless device falls within the distance constraint. interacting (108; 1102) with a second wireless device (106; 208) having internet-access capability and having capability to determine its own geographic location, to cause the second wireless device to obtain authorization to use a set of one or more radio white space frequencies at the geographic location of the second wireless device in accordance with one or more constraints; obtaining (120; 1104) authorization information including the constraints from the second wireless device; and, utilizing the authorized one or more radio white space frequencies to communicate with a third wireless device that is not the second wireless device, independently from the second wireless device that obtained the authorization; taking steps to ensure that the utilization complies with the constraints, wherein the one or more constraints include a distance constraint, comprising: determining a relative distance of the first wireless device from the second wireless device based upon the success or failure of communications with the second wireless device at a given frequency and power; and based on the determined relative distance, determining a transmission power for the first wireless device to transmit on the authorized one or more radio white space frequencies for which the maximum transmission distance from the authorized geographic location of the second wireless device falls within the distance constraint. determining a relative distance of the first wireless device from the second wireless device based upon the success or failure of communications with the second wireless device at a given frequency and power; and based on the determined relative distance, determining a transmission power for the first wireless device to transmit on the authorized one or more radio white space frequencies for which the maximum transmission distance from the authorized geographic location of the second wireless device falls within the distance constraint. <EOS>
