Abstract
A first beam is implemented, from a set of vehicle-based antennas, for current or future communication with a ground-based or satellite-based network via an external antenna (e.g., of a base station or satellite). A second beam may be implemented to detect or determine a better pointing angle for the first beam, thereby “fine tuning” the pointing angle for the first beam. Specifically, the second beam may be “swept” through a range of pointing angles while a signal parameter representing signal quality or strength is measured, detected, or calculated at each pointing angle. The values for the signal parameter may be evaluated to identify a desired value and the pointing angle at which the desired value was obtained. The first beam may be reoriented or repointed at the desired pointing angle, and one or more nodes of vehicle-based communication system may communicate with an external network via the first beam.
