Systems and methods for estimating a tag's location

A method for determining a location of a tag, comprising:

• receiving, by a plurality of detectors, a device transmission transmitted from the tag, where the plurality of detectors are respectively disposed in a plurality of zones defining an area through which the tag can pass;
• determining Received Signal Strength Indicators (“RSSIs”) for the device transmission received at the plurality of detectors;
• determining, by a computing device, a probable location of the tag within the area using the RSSIs, relationships between the RSSIs, and RSSI profiles respectively associated with the plurality of zones;
• determining a likelihood value indicating a probability that the probable location of the tag is correct;
• and
• using the probable location to generate an estimated location of the tag within the area if the likelihood value exceeds a threshold value.

A system, comprising:

• a tag;
• a plurality of detectors respectively disposed in a plurality of zones defining an area through which the tag can pass, and configured to
• receive a device transmission transmitted from the tag, and
• determine Received Signal Strength Indicators (“RSSIs”) for the device transmission received thereat;
• and
• a computing device communicatively coupled to the plurality of detectors, and configured to determine a probable location of the tag within the area using the RSSIs,
• relationships between the RSSIs, and RSSI profiles respectively associated with the plurality of zones,
• determine a likelihood value indicating a probability that the probable location of the tag is correct, and
• use the probable location to generate an estimated location of the tag within the area if the likelihood value exceeds a threshold value.
