In-building triangulation

I was just thinking about in-building triangulation in respect of tracking inventory in second hand shops, but come to think of it, where is in-building triangulation? Outside I can easily obtain my position through GPS, but I want to be able to do this in a building, to a resolution of 0.1m and including the floor of the building I am on. Would it be possible to triangulate using wifi routers?
