Patent ID: 7899007

Claim:
A system for voice communication over a plurality of networks, the system comprising: at least one processor coupled to a user interface and to radio frequency (RF) circuitry that communicates over an RF link, the at least one processor arranged to, at least: determine, in response to the user interface, a selection of one of a first network having a predetermined bandwidth and a second network having a variable bandwidth, the first and second networks operating substantially independent of one another; enable formatting of digitized voice information for the selected one of the first and second networks; cause the RF circuitry to communicate the formatted information over the RF link coupled to the selected one of the first network and the second network; and wherein in at least a first mode of operation, the system is arranged to conduct full-duplex voice communication over the first network, wherein in at least a second mode of operation, the system is arranged to conduct half-duplex communication over the second network, and wherein in at least a third mode of operation, the system is arranged to conduct full-duplex communication over the second network.
