摘要
The present invention includes a plurality of native cellular nodes configured to provide wireless connectivity to one or more ground-based wireless devices, each native node including a BTS having a transceiver configured to transmit a downlink signal to the ground-based devices at a native downlink frequency and receive an uplink signal from the ground-based devices at a native uplink frequency, a plurality of augmented nodes configured to provide connectivity to one or more airborne devices, each augmented node including an augmented BTS having a transceiver configured to transmit a downlink signal to the one or more airborne communications devices via an upwardly directed antenna at the native downlink frequency and receive an air-to-ground uplink signal from the airborne devices at a selected air-to-ground uplink frequency different from the native uplink signal frequency, wherein the native nodes and the augmented nodes are configured to operate on a common backhaul infrastructure.
