A method includes scanning beams of a multiple beam antenna to collect metrics associated with the beams; selecting a best beam based on the collected metrics or based on a manual selection received from an operator; retrieving thresholds associated with the metrics; comparing the collected metrics, associated with the selected best beam, to the retrieved thresholds; and determining whether the antenna unit is in an acceptable location based on the comparison. Another method includes scanning beams of the multiple beam antenna to collect metrics associated with the beams; selecting a best beam based on the collected metrics; determining a serving beam; comparing a set of metrics associated with the selected best beam with a corresponding set of metrics associated with the serving beam; and determining whether to switch from the serving beam to the selected best beam based on the comparison.
