Abstract:
Disclosed are examples of a method, system and asset tag that enables general, coarse and fine estimates of a location of the asset tag. The asset tag receives a signal transmitted from radio frequency (RF)-enabled nodes within a space. Each respective received signal includes a unique node identifier of the respective RF node that transmitted the respective received radio signal. Each RF node has a physical node location in the space that is associated with the unique node identifier. The tag measures the received signal strength of each respective received signal that is associated with the node identifier of the RF node that transmitted the respective received signal. The strongest measured received signal strengths are selected, and a tuple containing the node identifiers for the selected strongest signal strengths is forwarded for estimating a location of the asset tag by a computing device.

Claim (Index 15):
A method, comprising:\n receiving, from an asset tag coupled to a data communication network, a tuple containing at least three wireless node identifiers; retrieving data indicating a node location for the wireless nodes identified by the at least three wireless node identifiers included in the received tuple, the retrieved data including measured signal strengths; and estimating a location of the asset tag with respect to the node locations of the at least three node identifiers based on the order of the at least three wireless node identifiers in the received tuple and the retrieved data indicating the node location for each wireless node associated with the at least three node identifiers, wherein the estimating includes:\n for each pair of the respective measured signal strengths, calculating a respective delta value ratio; and \n decreasing or increasing a respective area of a respective region of a set of regions that segment a triangle or other polygon area of the space that the asset tag is located based on the respective delta value ratio; and \n forwarding the estimated asset tag location to an output device for presentation to a user.
