Abstract
A system for computing accurate position location coordinates of tags used for tracking assets and people include a first network of access points to help compute a first approximation of the tag position location, a second network of access points underlying the first network for fine position location determination, and a position location server for controlling the second network of access points and computing position location based on round trip delay measurements between tags and the access points.
