Abstract: An RF fingerprint of the environment of a base station antenna will be regularly monitored, such as by regularly evaluating various RF metrics of uplink reflections of downlink transmission from the antenna. Through regular monitoring of the RF fingerprint, a baseline RF fingerprint could be established. And through continued monitoring of the RF fingerprint, an unexpected change in the RF fingerprint could then be detected, as an indication that the antenna's RF beam direction may have changed. In response to detecting the unexpected change in the antenna's RF fingerprint, the antenna's RF beam direction could then be newly determined, and the antenna's configuration record could be updated to indicate the newly determined RF beam direction.
