  • Patent number: 10701515
    Abstract: Systems and methods for providing improved accuracy for beacon-based location systems. A location estimation system may include a multi-beacon system which includes two or more beacons positioned proximate each other. The beacons emit correlated beacon frames which are time and data correlated. A mobile device receives the beacon signals and processes them to estimate the distance between the mobile device and the multi-beacon system. The mobile device processes the signals based on a correlation function of the beacons signal strength trends, which indicates homogeneity and reliability of the acquired signals. When the correlation is high, the two or more RSSI signals are stable and may be used for the distance estimation. When the correlation is low, at least one of the signals is irregular. The mobile device compensates for the irregular signal, thus improving distance estimation accuracy.

  • Patent number: 9666948
    Abstract: An inter-satellite cross-link antenna for a communications satellite in a constellation of satellites in earth orbit. The complete cross-link system is an array of eight quadrifilar helix antennas with a new design which is eight times smaller than previous designs, and has superior inter-satellite communications performance. The quadrifilar helix antenna is designed with a length, diameter, helix pitch angle and ground plate connectivity which is matched to the UHF inter-satellite communication frequency to provided a toroidal radiation pattern with high signal strength in a direction normal to the antenna axis and very low signal strength in an axial direction.

  • Patent number: 9467893
    Abstract: The present disclosure discloses a system and method for classifying Wi-Fi signals from Fourier transform samples. Generally, classifying Wi-Fi signals from Fourier transform samples includes: collecting and dividing Fourier transform samples into frequency blocks; determining the bandwidth for the Fourier transform sample; and determining whether the Fourier transform sample corresponds to a narrowband signal. Further, if a determination is made that the Fourier transform sample does not correspond to a narrowband signal, channel utilization is calculated based on a determination that the FFT sample corresponds to a Wi-Fi signal. If it is determined that the Fourier transform sample corresponds to a narrowband signal, then a determination is made that the FFT sample corresponds to a Wi-Fi signal based on certain criteria. The certain criteria may include one or more of a slope value, a number of sub-peak bins, an analysis of adjacent channels, characteristic matching, or other criteria.
