发明名称 Security tag positioning
摘要 A tag controller is configured to interface with a security tag adapted to be disposed on a corresponding product in a monitoring environment. The tag controller includes processing circuitry configured to perform a tag position estimation by receiving information indicative of signal strength measured at the security tag relative to each of a plurality of locating beacons disposed in the monitoring environment, defining an order of a selected number of the locating beacons based on signal strength, determining a first midpoint between two of the selected number of the locating beacons having the lowest signal strengths, determining at least a second midpoint between the first midpoint and a locating beacon having a next lowest signal strength, and determining a location of the security tag at least in part based on the second midpoint.
