Abstract
A computer-implemented method for precision hyperbolic location fingerprinting, the method comprising, at a computing system, the steps of: (a) receiving measured RSSI values associated with a plurality of fixedly-positioned sensor devices, wherein the plurality of fixedly-positioned sensor devices are stationary in known locations in a 2D environment and caused to transit radio signals to each other and measure characteristics of the received radio signals; (b) generating a raw RSSI fingerprint for each sensor device based on the measured RSSI values; (c) generating a log-ratio RSSI fingerprint between a pair of sensor devices; (d) normalizing the raw RSSI fingerprint and normalizing the log-ratio RSSI fingerprint; (e) combining the raw RSSI fingerprint and the log-ratio RSSI fingerprint to form a fusion RSSI fingerprint; and (f) repeating steps (a) to (e) at predetermined intervals to enhance prediction accuracy of regional fingerprints within the environment.
