Claim Text:
1. A system of antenna sharing for asynchronous time-division duplex (TDD) radios comprising: a plurality of TDD transmitters, each transmitter operable on a predetermined set of channels and coupled via a respective transmit switch to an antenna, wherein each channel corresponds to an ultra-high frequency (UHF) television channel designation; a plurality of TDD receivers, each receiver associated with one of the plurality of TDD transmitter and operable on the predetermined set of channels and coupled via a respective receive switch to a splitter and in turn to an antenna; and a switch controller connected to respective transmit and receive switches for asynchronously connecting at least one TDD transmitter and at least one TDD receiver to the antenna for effecting antenna sharing among the plurality TDD receivers and TDD transmitters driven by a media access control (MAC) scheduler, and an integrated antenna -with plurality of co-located antennas and a circuit to limit co-located transmitter signals coupled to the transmit and receive switches; wherein when one of the plurality of TDD transmitter is connected to the integrated antenna when the respective transmit switch is closed, and the at least one TDD receiver associated with the respective at least one TDD transmitter is disconnected from the integrated antenna and the respective receive switch is open wherein more than one of the plurality of TDD transmitters can be transmitting at any one time.
