Abstract
An air-to-ground communications system includes at least one base station to be positioned on the ground and including a ground-based transceiver, a phased array antenna coupled to the ground-based transceiver, and a beamforming network coupled to the ground-based transceiver. The ground-based transceiver is configured to provide data traffic and control information to an aircraft. The beamforming network is configured to simultaneously generate at least one narrow antenna beam for the data traffic and at least one wide beam for the control information.
