Abstract: Systems and methods for filtering improbable locations are disclosed herein. An example system includes: a tag configured to transmit data while within one of a plurality of zones and a locationing engine. The locationing engine may be configured to: receive the data, analyze at least one property of the data to determine a current zone of the plurality of zones containing the tag with an associated confidence value, and analyze prior data transmitted from the tag to determine whether the current zone is different from a prior zone determined from the prior data. The locationing engine may also compare (i) a time differential between receipt of the prior data and receipt of the data and (ii) the associated confidence value with a cost value corresponding to moving from the prior zone to the current zone, and update a location of the tag based on the comparison.
