Patent ID: 7313411

Claim:
A wireless communication system comprising: a plurality of communication units, each of said units having: (a) a first receiver and a first transmitter, both operating in a first modulation mode, and (b) a second receiver and a second transmitter, both operating in a second modulation mode, said first receivers and said first transmitters of said units providing a first signal processing function for said system to receive a wireless message from outside said system on at least one of said first receivers and to transmit a wireless message from each of said first transmitters to receivers outside of said system, said second receivers and second transmitters of said units creating a second signal processing function for said system to transmit said message as a wireless message through other ones of said units and thus provide a link between a message received at one of said first receivers from outside said system to each of said units for wireless transmission from each of said first transmitters, a first mode to second mode message signal converter at each of said units to couple whatever message is received in said first modulation mode at said first receiver to said second modulation mode for broadcast by the second transmitter of the associated unit, a second mode to first mode message signal converter at each of said units to couple whatever message is received in said second mode at said second receiver to said first modulation mode at said first transmitter of the associated unit.
