<p>Power control for a group of mobile or portable radio transmitters and receivers (R1 to R6), which can operate in a direct mode, is achieved by arrangement that when one radio begins to transmit it operates at full power for a first period time. The power level is then decreased incrementally during subsequent time periods until one or more of the receiving radios signals that the received power level is at or below a given threshold.</p> |
