Patent ID: 7693488

Claim:
A method for avoiding interference during operation of a wireless communications system, comprising: setting an interference threshold value based on an amount of periodic errors received over a communications link; measuring a timing of errors received over the communications link at regular intervals; comparing the timing of the received errors with respect to a phase of an AC power source that powers the communications system and a microwave source; determining that a segment B interferer comprising segment B radiation from the microwave source is present when a consistent timing of the received errors with respect to the phase of the AC power source is detected, wherein the segment B radiation comprises a pair of high-level bursts of energy that occur at a beginning and an end of a half cycle of the AC power source during which a magnetron of the microwave source is powered; and initiating an asymmetric enhanced mode operation in the wireless device, wherein during the asymmetric enhanced mode operation the communications link is configured for redundant data transmission in only a single direction of the communications link.
