  • Techniques for wirelessly controlling push-to-talk operation of half-duplex wireless device
    Patent number: 7818036
    Abstract: Disclosed herein is a communications system implementing a headset wirelessly connected to a half-duplex communications device, such as a two-way radio or a radio-simulating cellular phone. The headset may incorporate a transmit/receive switch wherein a transmit signal is wirelessly transmitted from the headset to the communications device to direct the communications device to enter into a transmit mode. Alternatively, a wireless transmit/receive switch may be implemented separately from the wireless headset, where the wireless transmit/receive switch may be positioned in the proximity of the communications device and the headset and may be engaged by a user to direct the communications device to enter a transmit mode.
