Abstract:

An apparatus and methods are provided for network radio frequency ("RF") data communications. The apparatus preferably has an extended channel radio transmitter for selectively transmitting data communication radio signals across a plurality of different carrier frequencies which respectively define a plurality of extended data communication channels. The transmitter preferably includes a channel scanner for scanning the extended data communication channels for availability prior to transmitting across a selected one of the plurality of extended data communication channels. An extended channel radio receiver is responsive to the extended channel radio transmitter for receiving the data communication signals from the selected one of the extended data communication channels. The extended channel radio receiver preferably includes an extended channel data detection synchronizer responsive to the data communications signals being received by the receiver for synchronizing the transmitting and receiving of the data communication signals across the extended data communications channels. Any and all extended channel contending transmitters and receivers or transceivers within a network preferably sense and synchronize to the extended channel being transmitted within a predetermined period of time, i. e.
