Abstract:
The initial transmission (108) from one subscriber to another subscriber is transmitted at full power. The receiving unit measures the received signal strength and returns a code (118) representing this value in a reply message (114), which is also transmitted at full power. The signal strength of the reply message is determined and may be sent to the replying subscriber unit in a subsequent transmission (122), which may now be accomplished at a reduced power level. Thereafter, both subscribers may modify their respective transmitter power levels during subsequent transmission to minimize battery consumption and maximize the operational life of the subscriber unit.
