ABSTRACT:
An antenna steering algorithm for a smart antenna uses signal quality metrics and link quality metrics for selecting a preferred antenna beam. The link quality metrics supplement the signal quality metrics for improving the antenna steering decision. The link quality metrics are based on information available from existing counters operating in the media access control (MAC) layer. Separate estimates of the frame error rates in the receive links and in the transmit links are obtained. One estimate is the downlink quality metric (DLQM) and another estimate is the uplink quality metric (ULQM). Alternative link quality metrics are based on throughput and data rates of the exchanged data.
