Patent ID: 8831553

Claim:
A method comprising: activating a receive mode to detect a preamble; and alternately turning on, during a receive mode, at least some circuit blocks in a receive path of a receiver for a turn-on duration and then turning off the at least some of the circuit blocks for a turn-off duration, wherein the turn-off duration is shorter than the preamble, wherein a first measured value is measured in the receive path, wherein the first measured value is compared to a first threshold, wherein one or more of the length of the turn-on duration and the length of the turn-off duration is changed based on a result of the comparison with the first threshold, wherein the turn-off duration is terminated, the length of the turn-on duration is extended, and the circuit blocks remain turned on for synchronization by the preamble if a valid signal of the preamble is detected during the turn-on duration by comparison of a second measured value with a second threshold, and wherein one or more of the first threshold and the second threshold is adjustable as a function of one or more of a control value and a third measured value, wherein the third measured value is a field strength signal of a neighboring node; and wherein the control value is an existing boundary condition comprising one or more of a distance between nodes, interference sources, or neighboring networks.
