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 1):
A method, comprising:\n receiving, by an asset tag, a radio signal transmitted from each of three or more radio frequency-enabled nodes within a space, each respective received radio signal including a unique node identifier of the respective radio frequency-enabled node that transmitted the respective received radio signal, wherein each unique node identifier is associated with a specific node location in the space of the respective radio frequency-enabled node; measuring a received signal strength of each respective received radio signal; obtaining a respective transmitting node identifier from each of at least three of the respective received radio signals whose measured received signal strengths are strongest; generating a tuple containing an ordered list of at least three transmitting obtained node identifiers sorted by the respective measured received signal strengths; forwarding the tuple and the respective measured signal strengths to a tag location estimating application; and estimating, by the tag location estimating application, based on the generated tuple and the specific node locations associated with the obtained transmitting node identifiers, a location of the asset tag with respect to the specific node locations of the nodes associated with the obtained 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.
