Abstract
A smart antenna steering algorithm performs a self-monitored re-scan during a sustained use period after having selected a preferred antenna beam. During a sustained use period, a re-scan of the other antenna beams is not performed. The steering algorithm periodically monitors a quality metric of the ongoing radio link provided by the preferred antenna beam. The quality metric is based upon a signal quality metric and a link quality metric. If the quality metric drops below certain thresholds during the sustained use period, the steering algorithm either swaps the preferred antenna beam with an alternate antenna beam or initiates a re-scan of the available antenna beams for selecting a new preferred antenna beam.
