A system for providing wireless communication services to wireless subscriber devices that are located in aircraft (103, 104), the system comprising: a ground-based communications network (i) having a plurality of base stations (131, 133) located on the ground, each of which operates a respective at least one transceiver to create a respective coverage area that provides wireless communication services to wireless subscriber devices that are located in an aircraft that is operational in the respective coverage area, and the respective at least one transceiver of each base station comprising: Air-To-Ground Radio Frequency means for providing, via the respective at least one transceiver and a respective first antenna system means disposed at the each base station, a first at least one radio frequency communications link for bi-directionally interconnecting the ground-based communications network and an Aircraft In-Cabin Network of the aircraft, the first at least one radio frequency communications link operating using a first radio frequency band and having a first bandwidth for transmitting first communications signals between the respective at least one transceiver and the aircraft to thereby enable the wireless subscriber devices located in the aircraft to receive wireless communication services via the Aircraft In-Cabin Network while the aircraft is operational in the respective coverage area; and Broadband Ground-To-Air Data Channel means for establishing, via a respective second antenna system means disposed at the each base station, a second at least one radio frequency communications link, operating using a second radio frequency band and having a second bandwidth greater than the first bandwidth, with the aircraft for transmitting second communications signals between the respective at least one transceiver and the aircraft, the respective second antenna system means supporting beam steering to control energy radiation in the second radio frequency band towards the aircraft. Air-To-Ground Radio Frequency means for providing, via the respective at least one transceiver and a respective first antenna system means disposed at the each base station, a first at least one radio frequency communications link for bi-directionally interconnecting the ground-based communications network and an Aircraft In-Cabin Network of the aircraft, the first at least one radio frequency communications link operating using a first radio frequency band and having a first bandwidth for transmitting first communications signals between the respective at least one transceiver and the aircraft to thereby enable the wireless subscriber devices located in the aircraft to receive wireless communication services via the Aircraft In-Cabin Network while the aircraft is operational in the respective coverage area; and Broadband Ground-To-Air Data Channel means for establishing, via a respective second antenna system means disposed at the each base station, a second at least one radio frequency communications link, operating using a second radio frequency band and having a second bandwidth greater than the first bandwidth, with the aircraft for transmitting second communications signals between the respective at least one transceiver and the aircraft, the respective second antenna system means supporting beam steering to control energy radiation in the second radio frequency band towards the aircraft.
