  • Enhancing a push-to-talk communication system
    Patent number: 9118393
    Abstract: A peer-to-peer communication system (1) capable of operating in push-to-talk mode comprises terminals (2, 2A, 6) capable of push-to-talk, peer-to-peer radio communication, and an enhancing device (3) arranged for coupling with the terminal. The enhancing device (3) comprises: • an antenna (31) for transmitting and receiving radio signals, • a band-pass filter (32) for selecting a frequency band of the radio signals, • a bidirectional amplifier (33) for amplifying radio signals alternatingly in a transmitting and in a receiving direction, • a control unit (34) for controlling the bidirectional amplifier (32) in response to a sensor signal, and • a sensor (35) for detecting whether the terminal (2A; 6) is transmitting or receiving and for producing the sensor signal in response thereto, which sensor is galvanically isolated from the terminal. The communication system (1) may be a Terrestrial Trunked Radio system, commonly known as TETRA system, more in particular a TETRA system operating in Direct Mode.
