  • Patent number: 11885899
    Abstract: Methods and systems for generating map information of an environment using channel state information (CSI) of wireless signals received by access points (APs) in the environment are disclosed. In some implementations, a system uses CSI of a wireless signal received by a respective AP to determine a time-of-flight (ToF) and an angle-of-arrival (AoA) of one or more reflected path signal components of the wireless signal, and estimates the locations of points or surfaces in an area of the respective AP based on the ToF and AoA of the reflected path signal components. The estimated locations of the points or surfaces can be used to generate map information for the area. The system aggregates map information generated for different areas of the environment to determine map information for the entire environment. The wireless signals may be received from wireless stations or user equipment, or may be received from the respective AP.

  • Patent number: 11876553
    Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Such UWB systems through their receivers may operate in the presence of interfering signals and should provide for robust communications. Accordingly, an accurate and sharp filter that operates at low power is required and beneficially one that does not require a highly accurate power heavy clock. Further, many UWB applications require location and/or range finding of other elements and it would therefore be beneficial to provide a UWB based range finding and/or location capability removing the requirement to add additional device complexity and, typically significant, power consumption.

  • Patent number: 11864059
    Abstract: Techniques for calculating a location of a position consumer device is disclosed. In one example, a network server may create a fingerprint map from reference data points. Each of the reference data points may include a recorded geo-location of a position source device and signal measurements taken at that recorded geo-location. By initially estimating an initial position of the position consumer device, the network server may apply one or more threshold values to filter reference data points—candidates for interpolation. The network server may then perform an interpolation on one or more pairs of reference data points to find a pair of reference data points that is collinear with the estimated position of the position consumer device. The location of the position consumer device may then be calculated based upon geo-locations of position source devices that are associated with collinear reference data points.

  • Patent number: 11849371
    Abstract: During a positioning session, a user equipment (UE) is provided with an early uplink grant to respond to a request for location service information from a location server. The location service information, for example, may be a request for positioning capabilities, a request for positioning measurements or a position estimate, and may be a request for a single, periodic or triggered location information. The early uplink grant may be requested by the UE prior to needing the uplink grant, e.g., before the positioning measurements have been completed. The location server may instigate the early uplink grant, e.g., at or near the same time that the location server sends the request for information to the UE. The early uplink grant may be used, e.g., during high priority or emergency related positioning sessions, in order to reduce delay in the UE providing a response to the request for location information.
