Abstract:
1. A mobile unit for communicating with other mobile units assigned to a group within a Multipoint Voice Network (“MVN”) having a plurality of groups, the mobile unit comprising: a time division multiple access (“TDMA”) transmitter enabled to transmit on a set of multiple carrier frequencies, wherein the TDMA transmitter is configured to transmit on one frequency chosen from a selected sub-set of multiple carrier frequencies from the set of multiple carrier frequencies, wherein the one frequency chosen from the selected sub-set of multiple carrier frequencies corresponds to frequencies assigned to the group, wherein the TDMA transmitter is also configured to transmit utilizing a TDMA format that divides the transmitted data into multiple time slots, one time slot of the multiple time slots being configured for the TDMA transmitter; a TDMA receiver configured to receive and demodulate the selected sub-set of multiple carrier frequencies other than the frequency chosen for transmission by the TDMA transmitter; and a controller in signal communication with the TDMA receiver, wherein the controller selects the selected sub-set of multiple carrier frequencies and configures the TDMA receiver to receive and demodulate the selected sub-set of multiple carrier frequencies assigned to the group other than the frequency chosen for transmission by the TDMA transmitter.
