Claim Text:
1. A method for triggering re-beamforming, comprising: storing in a data storage device a first signal strength threshold; monitoring a plurality of data packets transmitted across a communication link, wherein the communication link is a 60 GHz communication link; recording a signal strength value for each of the plurality of data packets; calculating, with a processor, a change in the recorded signal strength value between data packets, wherein the change in the recorded signal strength between data packets is based on calculating a difference in the recorded signal strength between consecutive data packets; comparing, with the processor, the calculated change in the recorded signal strength between data packets with the first signal strength threshold; and when the calculated change in the recorded signal strength is less than the first signal strength threshold then triggering re-beamforming to establish a stronger communication path; wherein the calculating of the change in the recorded signal strength between consecutive data packets is executed N times, where N is an integer greater than 1, and wherein the re-beamforming is triggered only after the comparing of the calculated change in the recorded signal strength between consecutive data packets falls below the first signal strength threshold for a pair of consecutive data packets; after triggering re-beamforming to establish a stronger communication path determining if the first signal strength threshold needs to be changed; wherein the first signal strength threshold is a first threshold that is based on an unacceptable change in signal strength between consecutive data packets; in response to the determining that the first signal strength threshold needs to be changed then storing a second signal strength threshold; continuing the steps of measuring, recording, calculating, comparing, and triggering re-beamforming until packet transmission is complete.
