Measuring distance with radio waves is a three point process. The location two of the three points needs to be known and the antennas need to be directional. This article explains triangulation: http://searchnetworking.techtarget.com/definition/triangulation
Wifi devices do not have directional antennas and you will normally only know the location of the wireless router. You would have to find or build special radio receivers to measure distance by radio.
