Abstract:
1. A method for reducing interference in a communication channel used by at least one of a plurality of first transceivers to initiate communication with a second transceiver, said method comprising the steps of: selecting, randomly, a first time delay within a predetermined range; transmitting from said at least one first transceiver an access probe at a first power level after said first randomly selected time delay, said first power level being determined on the basis of amount of power at which a signal transmitted from said second transceiver is received; determining whether said access probe has been received at said second transceiver based on reception of an acknowledgement from said second transceiver; if said access probe has not been received, selecting, randomly, a second time delay within said predetermined range; and retransmitting said access probe, after said second randomly selected time delay, from said at least one first transceiver at a power level greater than said first power level.
