Architecture for integration of multiple networks in an air-to-ground context
An inter-network communication controller may include processing circuitry. The processing circuitry may be configured to receive location information associated with an in-flight aircraft being tracked and provided with air-to-ground (ATG) wireless communication services by a first ATG network. The first ATG network may employ beamforming directed to the aircraft to provide the communication services. The processing circuitry may also be configured to provide the location information to a second ATG network to enable the second ATG network to utilize the location information for employing beamforming to establish wireless communication with the aircraft. The first ATG network and the second ATG network may each operate over different ranges of radio frequency (RF) spectrum.

provide the location information to a second ATG network comprising a second set of two or more ATG base stations that do not share the common backhaul of the first set of two or more ATG base stations to enable the second ATG network to utilize the location information for employing beamforming to establish wireless communication with the aircraft,

an inter-network communication controller comprising processing circuitry configured to:
receive location information associated with the aircraft being provided with communication services by the first ATG network, and
provide the location information to the second ATG network to enable the second ATG network to utilize the location information for employing beamforming to establish wireless communication with the aircraft,
wherein the first ATG network and the second ATG network each operate over different ranges of radio frequency (RF) spectrum.
