Patent ID: 6985456

Claim:
A method of power control for use in a communications network having plural transceiver communications nodes therein, comprising: in an initiator node, transmitting a first signal at a first power level to a responder node; in the responder node, measuring and storing, a first signal level for the first signal and a first signal responder noise level; determining responder reception characteristic information; and sending a second signal to the initiator node; in the initiator node, measuring and storing, a second signal level and second signal initiator noise level; determining initiator reception characteristic information; and sending a third signal to the responder node; in both the initiator node and the responder node, determining a subsequent data transmit signal power and data rate; and transmitting data at the subsequent data transmit signal power and data rate, wherein power control is initiated by collision sense power control including initiating power control as a function of the number of collisions when plural nodes contend for a channel.
