Abstract

A system and method for location of objects in 2-dimensional and 3-dimensional space using a minimum number of timed RF transmissions. System consists of a mobile device and a plurality of surveyed anchors. Two-Way Ranging (TWR) is done between the tag and any single anchor and the distance between the tag and remaining anchors is determined through listening to, or snooping, the TWR packet transmissions.
