  • Patent number: 10187140
    Abstract: A communication system is described. The system includes: at least one gateway able to provide broadband connectivity, a set of ground terminals, and a set of aerial platforms, where at least one aerial platform is able to communicate with at least one gateway using radio frequencies, each aerial platform is able to communicate with ground terminals using radio frequencies, and each aerial platform is able to communicate with each other aerial platform using radio frequencies. An automated method for determining a beam direction for communication among UAVs includes: dividing a space around the UAV into multiple sub-regions, and, iteratively: selecting a sub-region from among the multiple sub-regions; pointing a signal toward the sub-region; and determining whether a signal is received from another UAV, until all sub-regions from among the multiple sub-regions have been selected.

  • Patent number: 10181893
    Abstract: Systems and methods configured to form and point beams from an unmanned aerial vehicle (UAV) toward target cells in a coverage area on the ground. One embodiment determines and forms the required number of UAV fixed beams needed to cover the target area when UAV is at its highest altitude and highest roll/pitch/yaw angles so that the target coverage area is covered under all UAV altitude and orientation conditions. In another embodiment, UAV determines the beam pointing angles toward different cells on the ground using information on position coordinates and orientation angles of the UAV, and the position coordinates of the cells in the coverage area relative to the center of coverage area. In another embodiment, a reference terminal placed at the center of coverage is used by the UAV to optimally point a beam toward center of the coverage area.

  • Patent number: 10153829
    Abstract: Systems and methods for detecting an unmanned aerial vehicle (UAV). Network access (for example, to the Internet) may be provided by detecting a UAV and fixing one or more beams from one or more ground terminals to the UAV. In one embodiment, the detection of a UAV includes forming and pointing beams from a ground terminal and ground gateways toward the UAV. The ground terminal may be configured to autonomously steer its antenna beam during initial installation to detect the reference signal from a UAV. In one variant, the ground terminals are steered to more finely track the position of the UAV based on a signal quality metric such as received signal strength and the UAV real-time position location coordinates. In one embodiment, the ground terminal antenna is initially manually pointed toward the UAV, and thereafter allowed to automatically steer to track the position of the UAV.

  • Patent number: 10003915
    Abstract: A position location system based on a wireless local area network such as an IEEE 802.11 network is described. The system determines position of mobile tags attached to assets or people. IEEE 802.11 enabled zone tags are installed to assist in positioning. The system aligns frame timing of zone tags to that of an associated basic service set (BSS). The system computes the frame timing offsets between adjacent BSSs, and utilizes the frame timing offsets in scheduling range measurements between zone tags and mobile tags. A set of zone tags which are in close proximity of a first zone tag and able to receive signals from the first zone tag is identified. Frame timing of all zone tags in a network are aligned.

  • Patent number: 9998859
    Abstract: A position location system is described for determining position of mobile Tags attached to assets or people. Zone Tags are installed in the venue to assist in position location estimation of mobile Tags. Time is divided into intervals, each interval comprising at least one range measurement sub-interval, and an idle sub-interval where zone Tags and mobile Tags go to sleep to save power. A zone Tag or mobile Tag is designated as the anchor network element. The anchor network element contends and seizes the communications channel at the beginning of each interval to start the range measurement phase. Mobile Tag position location estimates are made periodically. Between the periodic range measurement based position estimates, mobile Tag sensor readings are used to update the mobile Tag's position location. The period between range measurement based position updates is adjusted based on the statistics of the differences between the range measurements based position estimate and the sensor based position updated.

  • Patent number: 9980267
    Abstract: Systems and methods configured to form and manage different types of beams toward target ground terminals to “optimally” communicate with the terminals. In one set of embodiments, the UAV generates a set of beams to cover cells on the ground, the beams are divided into groups, and the UAV communications system deterministically and sequentially turns a subset of the beams on/off to reduce cross-beam interference and increase system throughput. In another embodiment, in order to increase throughput, the UAV communications system determines the highest data rate on the downlink and uplink that are decodable at the receiver given the received signal to interference plus noise ratio (SINR) while maintaining a low packet error rate. Systems and methods are described to determine the UAV antenna pattern toward different terminals needed for SINR calculation and data rate determination.

The modulator modulates the modulation symbol vectors to provide a modulated signal suitable for transmission. The data from each coded data stream is mapped to a respective set of one or more “circuits”. Each circuit can be defined to include a number of tones from a number of OFDM symbols, a number of tones from a single OFDM symbol, all tones from one or more OFDM symbols, or some other combination of tones.
