Abstract:
A cellular communication system having at least first and second transceivers, each transceiver comprising a transmitter and a receiver, the cellular communication system comprising:a first transceiver comprising:a first receiver for receiving a second transmitted communication signal; anda first transmitter which transmits a first transmitted communication signal at a variable and controllable first power level and a first transmitter level signal which is representative of said first power level of said first transmitted communication signal;a first controller means for adjusting and controlling the power level of said first transmitted communication signal to a desired signal strength;said first transmitter continually transmitting said first transmitter level signal during the transmission of said first transmitted communication signal;a second transceiver comprising:a second transmitter for transmitting said second transmitted communication signal at a variable and controllable second power level;a second receiver for receiving said first transmitted communication signal and said first transmitter level signal;a measurement means for measuring the signal strength of said first transmitted communication signal;a processor means for continually processing said first transmitter level signal and said signal strength of said first transmitted communication signal to produce a path loss estimate; anda second controller means for adjusting and controlling said second power level of said second transmitted communication signal in accordance with said path loss estimate.
