We've thought about strength for a while, but in the end it doesn't work
very well.  There are simply too many things that can affect AP signal
strength to use it as a reliable measure of where you are.  It's better
to use *more than one* AP and triangulate to get better accuracy than
just 100m radius of one AP's known location.  Using only one AP, if
somebody turns on a microwave or uses a 2.4GHz DECT phone, suddenly it
looks like you're 30 meters farther away from the AP than you were 10
seconds ago...
