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.
Abstract:
Methods and apparatus for providing distributed airborne wireless communications are provided. An airborne wireless communication system may include: an airborne fleet comprising a plurality of airborne platforms; a distributed communication payload subdivided into parts, each distributed on respective airborne platforms. The communication payload comprises air-to-user link equipment and air-to-air link equipment to provide communications between the airborne wireless communication system and end-users and between individual airborne platforms; and payload control electronics to control the air-to-user and air-to-air equipment and manage operation of the airborne wireless communication system. The air-to-user link equipment comprises an RF antenna to produce an RF beam in a direction towards the ground. A communication cell is defined on the ground and in the airspace below the fleet bounded by a boundary of the RF beam. The air-to-user communication equipment is configured to provide communication links between the airborne fleet and end-user devices within the communication cell.
Abstract:
Methods and apparatus to harvest renewable energy are provided herein. In some embodiments, a wind-powered aircraft includes an airframe suitable for untethered flight in an open airspace; and an airborne kinetic energy conversion system attached to the airframe, the airborne kinetic energy conversion system comprising a turbine, a generator connected to the turbine, and an electrical storage means connected to the generator.
