  • Patent number: 11768266
    Abstract: Approaches are described for antenna configuration in an antenna array of limited array size and channel state information (CSI) collection and analysis, to improve accuracy of angle of arrival (AoA) estimations for localizing a client device's position. Signals can be received from groups of antennas and CSI data can be generated from the signals. The CSI data can be combined, where the combined CSI data represents CSI data measurements of multiple signals received from a plurality of antenna subsets, without requiring physical installation of additional antennas to the limited antenna array to make the CSI data measurements. The angle of arrival (AoA) of the signals is estimated based on the combined CSI, and the AoA estimation can be used to determine the client device's location, and for other location services, such as identifying a person's location, tracking and managing inventory of objects, commute prediction, and the like.

  • Publication number: 20230221399
    Abstract: A device for estimating a fixed position of a wireless communication is provided. The device comprises a radio connected to an antenna array, a memory and a process. The radio can receive a first signal transmitted from a first direction by the wireless communication device to the movable device, and a second signal transmitted from a second direction by the wireless communication device to the movable device. The processor can calculate a first angle of arrival (AOA) a second AOA. The processor can estimate the fixed position of the wireless communication device based on the first AOA, the second AOA, the first position and the second position.
