Abstract

Embodiments of methods for providing distributed airborne wireless communications are provided herein. In some embodiments, a method of providing wireless communication services includes: receiving a radio frequency (RF) signal from a first area by a distributed airborne communication payload, wherein the distributed airborne communication payload is comprised of sections located on respective ones of a plurality of airborne platforms; relaying the RF signal along the sections located on different airborne platforms; and transmitting the RF signal to a second area.

Claims

relaying the first RF signal along the sections located on different airborne platforms, the relaying comprising receiving the first RF signal over a first channel frequency at a first airborne platform and transmitting the first RF signal, at the first channel frequency or at a second channel frequency, from the first airborne platform to a second platform airborne platform to produce an air-to-user (ATU) link;

transmitting the first RF signal to a second area; and

transmitting a second RF signal between the first airborne platform and second airborne platform to set up and control operation of the ATU link;

wherein the method further comprises;

providing a plurality of airborne platforms with predetermined payload power and weight capabilities;

providing communication payload sections, wherein each section has power and weight requirements that can be satisfied by the capabilities of at least one single airborne platform; and

mounting the communication payload sections onto the airborne platforms and forming an airborne fleet with net communication payload capabilities of an airborne wireless communication node.
