Abstract
A technique for a wireless device to obtain white space information from a component configured for cellular communication, such as a cellular phone. The wireless device and cellular phone may communicate using a short-range connection, such as a peer-to-peer connection, ensuring that the white space information, which is location based, generated by the cellular phone is also accurate for the location of the wireless device. With such white space information, the wireless device can comply with regulatory requirements for white space use by accessing a regulatory database identifying, by location, available white space channels. When the cellular phone is configured for accessing a wide area network, the cellular telephone may provide the white space information as a set of channels available for white space communication. Channels of the set may be prioritized based on one or more parameters, including frequency, permitted transmit power or detected noise.
