A wireless telephone system having a plurality of wireless, battery-powered handsets and a base unit, the base unit having a base transceiver. Each handset has a handset transceiver for establishing a wireless link over a shared channel with the base unit via the base transceiver, wherein the base transceiver transmits to a given handset transceiver a forward data message, which contains forward power level information identifying a forward power level at which the forward data message was transmitted by the base transceiver. The receiver receives and locks onto the forward data message. The transmitter transmits to the base transceiver a return data message at a return power level determined in accordance with the forward power level information.

1. A transceiver for communicating with a second transceiver, the transceiver comprising:a receiver for receiving and locking onto a forward data message transmitted by the second transceiver, wherein the forward data message comprises forward power level information identifying a forward power level at which the forward data message was transmitted by the second transceiver and a downlink data packet transmitted by the second transceiver before a communications link is established; and the return data message comprises a return channel link is established; and the return data message comprises a return channel link data packet transmitted by the transceiver after the transceiver locks onto the forward signal; a transmitter for transmitting to the second transceiver a return data message at a return power level determined in accordance with the forward power level information; wherein the transceiver being a handset transceiver of a first wireless handset; the second transceiver being a base transceiver of a base unit; when a communications link is not established between the base transceiver and the handset transceiver, the handset transceiver periodically transmits successive downlink data packets at successively higher power levels until a maximum power level is reached, each successive downlink data packet comprising a power level field for identifying the power level at which each said successive downlink data packet is transmitted.
