  • Patent number: 6804515
    Abstract: A wireless communications system infrastructure includes an integrated unit of RF and switch components mounted on a transportable platform for providing a communications link to a public switched telephone network. An airplane for executing a predetermined flight pattern includes a repeater for communicating with the integrated unit of RF and switch components and provides a link between the integrated RF and switch components and operational handsets within a repeater geographic area of coverage corresponding to the flight pattern. The wireless communications system infrastructure is therefore capable of being positioned strategically with respect to terrestrial cell stations and with respect to a flight pattern of the plane carrying the repeater to provide coverage to areas that otherwise may be out of range of an airborne repeater and conventional wireless system infrastructure components.

  • Patent number: 6795699
    Abstract: A method of locating a billing area associated with a cell phone call initiated in an airborne cellular communications system enables service providers to more accurately identify system user locations within the system's area of coverage. In operation, propagation delay and beam number location of an initiated call are identified to determine a current handset radial beam location. The propagation delay is then mapped to a stored closest corresponding radial geographic billing location, and the call is then associated with the closest corresponding radial geographic billing location. Additional system accuracy may be provided by determining azimuthal position within a beam footprint by determining a handoff location of a signal from a first beam to a second beam, and then mapping handoff information to a closest corresponding azimuthal geographic billing location. Both the closest corresponding radial and azimuthal geographic billing locations are then used to identify a current handset location.
