ABSTRACT:
A system and method for effectively performing a transmit power adjustment procedure in a wireless network includes a forward receiver that monitors a wireless forward link for forward data that is transmitted over the wireless forward link by a forward transmitter. The forward transmitter initially transmits the forward data at a minimum power level, and gradually increases the minimum power level to a power level threshold at which the forward receiver first detects the forward data on the forward link. Once the forward receiver and the forward transmitter are successfully coupled over the wireless forward link, the forward transmitter may then transmit forward data at a normal operating power level. The foregoing transmit power adjustment procedure ensures that the forward receiver receives forward data only from the forward transmitter, and prevents other proximate wireless devices from inadvertently intercepting forward data transmitted by the forward receiver.
