I always thought a reasonable solution to this problem was triangulating via wifi and bluetooth signal strength from access points of known location. I tried it as a weekend project a few years ago but random fading was a killer and I never got it to work that well. Seems like it should be possible though. Are there good reasons not to do it this way?

Not everywhere has wifi and bluetooth (yes, places exist outside of the wired world) and from the article it seems that an application area of interest is underground mining where transmitting radio through tunnels is already problematic.
