ABSTRACT:
A method of determining a location is provided. The method comprises placing a plurality of radio frequency (RF) tags within an area, mapping the placement of the plurality of RF tags within the area, detecting one or more of the plurality of RF tags in the area, and determining a location based in part on the mapping and on probability distributions associated with each of the one or more detected RF tags.
