Patent ID: 7349691

Claim:
A system for performing wireless communications, comprising: a broadcast transmission system configured to transmit broadcast information by employing wide-area FM subcarrier broadcasting on a predetermined schedule, wherein the broadcast information includes information for being conveyed to a user interface of a mobile device; a localcast transmission system configured to transmit local information over a local area, wherein the local area is smaller than the wide area; a peer-to-peer transmission system configured to transmit peer information; and a mobile device comprising a transceiver that is configured to: receive the broadcast information when the transceiver is in a broadcast mode and convey the broadcast information to the user interface of the mobile device; receive the localcast information when the transceiver is in a localcast mode and convey the localcast information to the user interface of the mobile device; transmit localcast information when the transceiver is in a localcast mode; receive peer information when the transceiver is in a peer-to-peer mode and convey the peer information to the user interface of the mobile device; transmit peer information when the transceiver is in a peer-to-peer mode; transmit from a signal processing unit receive commands that describe a receive frequency, antenna tuning parameters, and a duration of capture time; and adjust a variable tuning element to tune the antenna assembly in response to the receive commands.
