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.

Abstract: Systems and methods for improving tag locationing are disclosed herein. An example system comprises: a plurality of tags configured to transmit data in response to requests; and a gateway that polls the plurality of tags at a first polling rate. The gateway may be configured to: receive a first request, in response to receiving the first request, transmit a signal to the plurality of tags that causes a first subset of the plurality of tags to transmit the data at a second polling rate that is different from the first polling rate, and receive the data from a second subset of the plurality of tags at the first polling rate.
