  • Patent number: 10257716
    Abstract: In one implementation, interference generated by a constellation of satellites is mitigated. Each satellite is configured to provide multiple beams that define a coverage footprint. Anticipated positions are determined for satellites. Based on the anticipated positions, a determination is made that, during a defined period of time, portions of a coverage footprint for a first satellite will be covered by coverage footprints for other satellites. Based on this, a beam assignment for the first satellite is defined in which a first subset of beams configured to provide coverage of a first portion of the first coverage footprint are inactive, and a beam assignment for a second satellite is defined in which a second subset of beams are active, where the second subset of beams provide coverage within the first portion of the first coverage footprint.

A polarization or magnetisation current can be generated, in a controlled manner, whose distribution pattern has an accelerated motion, so that non-spherically decaying and intense spherically decaying components of electromagnetic radiation can be generated. The coordinated motion of aggregates of charged particles can give rise to extended electric charges and currents. The charged distribution patterns can propagate with a phase speed exceeding the speed of light in vacuo and that, once created, such propagating charged patterns act as sources of electromagnetic fields in precisely the same way as any other moving sources of these fields. That the distribution patterns of these sources travel faster than light is not, of course, in any way incompatible with the requirements of special relativity.

  • Patent number: 9521520
    Abstract: A particular first wireless device having a plurality of antennas and that is part of a group of a plurality of first wireless devices, transmits to a second wireless device (whose location is to be determined) a packet across the plurality of antennas of the particular first wireless device simultaneously with a plurality of packets transmitted by a corresponding one of other first wireless devices in the group. The packet transmitted by the particular first wireless device uses a subset of a set of subcarriers available for use in the packet such that substantially the entire set of subcarriers are used in the aggregate across the plurality of packets simultaneously transmitted by the plurality of first wireless devices in the group to the second wireless device. The simultaneous reception of the plurality of packets at the second wireless device enables the second wireless device to determine its location.

  • Patent number: 9479243
    Abstract: The present invention features novel methods of implementing configurable arrays for personal portable devices including hand-held mobile devices and re-locatable wireless devices, utilizing a wireless communications system that employs multiple individual hubs and/or base-stations. The digital beam forming (DBF) methodology utilizes multiple low gain elements conformal to the mechanical contours of handheld devices to function as arrays. The distributed N element arrays dynamically provide the options of reconfigurable shaped beams with near hemispheric radiation patterns for various handheld orientations and conditions by various users, while also supporting operations of multiple orthogonal beams concurrently connecting to multiple hubs. The larger the N becomes, the more flexibility the residing devices can provide.

  • Patent number: 9425888
    Abstract: Methods for providing high-speed connectivity to an aircraft in flight from a satellite. Example methods include transmitting first radio frequency signals from a wide-beam antenna at the satellite at a beamwidth of at least 6 degrees orbital arc to provide a wide coverage area. The first radio frequency signals are transmitted at a first frequency of at least 10 gigahertz and at a low equivalent isotropic radiated power. The method also includes receiving second radio frequency signals from a mobile antenna located on the aircraft, wherein the second radio frequency signals are received at a second frequency of at least 13.75 gigahertz, and the second frequency is different than the first frequency.

  • Patent number: 9398468
    Abstract: Cellular array implementations with multiple steerable spotlight beams irradiated from a common aperture are disclosed herein. Such an approach can easily be adapted to suit various geographical population densities and distributions. The array is capable of producing multiple 65-degree cellular coverage beams, which may be used for regular coverage or in MIMO (Multiple Input Multiple Output) mode. The array may also produce multiple steerable beams, or “spotlight” beams. These beams may be relatively narrow and may be steered electronically both in azimuth and elevation directions. By steering the beams in this way, the beams are able to provide cellular services at high-demand “hotspot” regions where high capacity service is required. The spotlight beams may also be used to fill voids or deficiencies caused by regular coverage beams.

  • Patent number: 9391761
    Abstract: An information handling system includes a first subsystem having a first data module configured to provide a first signal, a second data module configured to provide a second signal, the first signal and the second signal are different types of signals, and a first aggregator unit coupled to the first data module and the second data module, and a second subsystem coupled to the first aggregator unit via a first aggregated signal line. The first aggregator unit receives the first signal from the first data module and the second signal from the second data module, aggregates, based upon a first aggregation algorithm, the first and second signals to create a first aggregated signal. The first aggregation algorithm aggregates the first signal and the second signal based on a specific type of each signal and provides the first aggregated signal to the second subsystem via the first aggregated signal line.

  • Patent number: 9306657
    Abstract: A method of providing a communication link for a mobile platform. The method may involve generating a single beam and controlling the single beam to simultaneously generate first and second communication lobes from the single beam, with the first communication lobe being steered to communicate with a first base transceiver station (BTS). The method may further involve simultaneously using the second communication lobe to communicate with the second BTS and fading out the first lobe so that communication with the mobile platform is transferred to the second BTS.

  • Patent number: 9125107
    Abstract: Disclosed herein is a method for determining the location of a mobile station with greater accuracy than serving base station location and yet preferably without the consumption of network resources typical of satellite-based location determination. The method is applicable in a scenario where a mobile station is ping-ponging (or has just been ping-ponging) between two non-coterminous wireless coverage areas. According the method, in that scenario, the location of the mobile station will be approximated conveniently as the location of overlap between the two wireless coverage areas, since it is most likely that the mobile station resides in that overlap area.

  • Patent number: 9024817
    Abstract: One embodiment is directed to an aircraft position report system. The system comprises a satellite, an aircraft position reporting receiver mounted on the satellite, an antenna element mounted on the satellite, and an antenna interface mounted on the satellite. The aircraft position reporting receiver receives aircraft position reports through the antenna element by associating a spot beam with a narrow coverage area. The aircraft position reports are derived from a signal produced by the antenna element. The antenna interface changes the narrow coverage area associated with the spot beam to receive aircraft position reports from a wide coverage region within a reporting period. In one exemplary embodiment, the antenna interface mechanically steers the spot beam for each receiver to one of the narrow coverage areas. In another exemplary embodiment, the antenna interface electronically steers the spot beam for each receiver to one of the narrow coverage areas.
