Uwb-based Side of Door Detection for Intent Analysis
28 Dec 23
A method according to an embodiment includes receiving UWB data indicative of a distance of a mobile device relative to the access control device and a SNR of signals received by a plurality of UWB antennas, inferring a side of the passageway at which the mobile device is located based on the distance of the mobile device relative to the access control device and also based on the SNR of the signals, estimating a travel time of the mobile device to the passageway based on the UWB data if the inferred side of the passageway based on the distance of the mobile device is different from the side of the passageway inferred based on the SNR of the signals, and determining the side of the passageway at which the mobile device is located to be an unsecure side of the passageway if the travel time exceeds a predefined threshold time.
