Patent ID: 8848914

Claim:
A method of operating a first peer communications device, the method comprising: communicating authentication and authorization information to a spectrum access key source as part of an authentication and authorization process; receiving a first spectrum access key from the spectrum access key source in response to the communicating the authentication and authorization information to the spectrum access key source, wherein the first spectrum access key provides access to a licensed frequency spectrum for peer-to-peer wireless communications; receiving a first signal from a second peer communications device, wherein the first signal comprises a broadcast timing signal generated by the second peer communications device; generating a first pseudo-random bit sequence based on the first spectrum access key and based on the received broadcast timing signal generated by the second peer communications device; and using the generated first pseudo-random bit sequence to communicate over a peer-to-peer air link with a third peer communications device that has also received the first spectrum access key from the spectrum access key source and the broadcast timing signal from the second peer communications device.
