A mobile device for use in a peer-to-peer radio communication network coupled to a cellular radio communication network. The mobile device comprises a cellular radio transceiver, a short range radio transceiver configured for radio communication using unlicensed radio spectrum over short ranges, a non-transitory memory, a processor, and an application stored in the non-transitory memory. When executed by the processor, the application discovers a plurality of peer mobile devices based on communication with these peer mobile devices using the short range radio transceiver, identifies at least one base transceiver station to which at least one of the discovered peer mobile devices provides a peer-to-peer network link, and initiates a data link to a first base transceiver station via a first discovered peer mobile device in the peer-to-peer radio communication network based on a geographical route list.
