  • METHOD AND SYSTEM FOR LOCATION ESTIMATION
    Publication number: 20180199149
    Abstract: A method includes configuring a physical environment with Bluetooth Low Energy (BLE) beacons where a transmit power of the BLE beacons is selected such that (a) wireless devices at particular physical zones within the physical environment receive Bluetooth signals from respective BLE beacons, and (b) physical zones corresponding to BLE beacons are separated by non-BLE-zones. A method includes determining that a wireless device is not located within any physical zones corresponding to BLE beacons, and in response, (a) identifying a last physical zone in which the wireless device was located, (b) determining a trajectory of the wireless device subsequent to detection in the last physical zone, and (c) estimating the location of the wireless device based on the last physical zone in which the wireless device was detected and the trajectory of the wireless device since the detection in the last physical zone.
