Sensed situation millimeter-wave communications beam control
The present disclosure relates to a system includes an antenna disposed on a pole and a beam control unit disposed on the pole and operably coupled to the antenna. The beam control unit includes one or more sensors configured to detect one or more parameters related to tilting or bending of the pole. In addition, the beam control unit is configured to determine a misalignment of an antenna boresight as compared to an initial antenna boresight direction and to re-align the antenna boresight to the initial antenna boresight direction.
