Isn’t this actually triangulating your position based on cell towers not the WiFi signal (when GPS is turned off)?

The big blue circle is about 1/2 mile in radius. I am in an office building with a good wireless network, in the center of Virginia Beach, a pretty good sized metropolitan city. The position on the map stays pretty consistent there, but every once in a while, it will hop up about 3/4 of a mile to the north west. I think it is using cell towers for triangulation right now. What's more, when I turn GPS back on, the behavior is pretty much the same, so the phone is recognizing that the cell/WiFi is the better source right now. It just seems to me that the phone should be able to know that I could not possibly be 1/2 mile to the south right now because of the fact that it can see the wireless network in my building right now. There is no way the phone could see that nework if I was actually at the spot where it thinks it is.
