Abstract
Provided are a system and method for geolocation of a tag relative to a predetermined threshold based upon receipt of duplicate beacon transmission for a same channel. In response to the duplicate transmission, the tag determines relative phase shift resulting from difference in path length, and evaluates correlation of a highest magnitude phase shift to the absence of any difference in path length to assess proximity of the tag with respect to the aforementioned predetermined threshold.
