Abstract

Various embodiments provide a method and apparatus for determining tag location by using one or more estimated channel responses (CR) that characterize the wireless channel between the tag and one or more respective anchors. In particular, a tracking server in communication with the anchor(s) determines the tag's location based on a comparison of the estimated CR(s) with a set of stored CRs associated with the anchor(s).
