A broadband wireless system includes a plurality of spaced-apart ground stations for transmitting and receiving signals to and from a respective plurality of aircraft. Each of the plurality of ground stations may include a ground station transceiver including a ground station antenna carried by a mechanically steered platform, a ground station router in communication with the ground station transceiver, and a ground station beacon transceiver in communication with the ground station router. An aircraft transceiver may be carried by each of the plurality of aircraft to be positioned in communication with one of the plurality of ground stations. The aircraft transceiver may include an aircraft antenna mounted to the aircraft, an aircraft transceiver carried by the aircraft and in communication with the aircraft antenna, and an aircraft radio transceiver carried by the aircraft and in communication with the aircraft beacon transceiver. The broadband wireless system may also include a network operations center in communication with each of the ground stations via a global communications network. A ground station transceiver may transmit signals to and receives signals from not more than one aircraft at a time and ground station antenna may track the aircraft with which it is in communication.
