    摘要： A communication system has a plurality of bases stations generating communication portions from a base station communication signal. The plurality of base stations are capable of using the entire allocated bandwidth to generate the base station communication portions. A user terminal establishes a plurality of dynamic links corresponding respectively to the plurality of base stations. The user terminal generates multiple communication portions of a user signal and transmits the multiple communication portions through the dynamic links to the plurality of base stations. The user terminal receives the base station communication portions from the plurality of bases stations and reassembles the communication portions into the base station communication signals.

    摘要： A mobile communication system includes at least one user terminal and a plurality of satellites which transmit and receive a plurality of communication signals to and from the user terminal. The communication signals transmitted to and received from the plurality of satellites by a gateway station. The gateway station in turn is in communication with a processing center to process said communication signals. The processing center uses polystatic triangulation to determine a position of the at least one user terminal and redirect a signal from at least one said plurality of satellites in response to the determined position of the at least one user terminal.

    摘要： A communications system (10) and method of operating the communications system includes a high altitude communication device (12) that communicates with a plurality of user terminals and a gateway station (30). The gateway station (30) couples the users to terrestrial networks (32) and other users. The high altitude communication device (16) has a controller that generates a second beam having the first frequency to a service (26). The stratospheric platform (12) does not generate the second beam within a blocking area. User terminals within the service area outside the blocking area are configured to receive the first beam and the second beam.
