Abstract: In the method, communication is established between a mobile device and access points in a wireless local area network by first connecting to a first access point on a first channel. After the first connection is established, the method determines whether a second access point is available before disconnecting from the first connection. If a signal strength of the first connection drops below a signal strength threshold, the method second connects to the second access point on a second channel. The above-described method is an example of a make-before-break or soft handoff methodology.

Abstract: Methods and systems for rectifying deteriorated channel conditions on a communication link are described. In response to the detection of a link deterioration event, a cluster of beams about a currently utilized beam pair can be trialed to determine a suitable, alternate pair of beams on which to establish a communication link. In turn, in the case of a link blockage event, a set of beams having a relatively large azimuthal angle with respect to a currently utilized beam pair can be trialed to determine a suitable beam pair for further communication.

The beam pattern vectors are perturbed to produce a plurality of perturbed transmit and receive beam pattern vectors. A received signal power between the transmitter and the receiver is estimated for each combination of the perturbed transmit and the perturbed receive beam pattern vectors. The transmit and receive beam pattern vectors having a highest received signal power are applied to the transmitter and the receiver respectively. The perturbation, estimation, and application steps are iterated until the received signal power meets a convergence criterion.
