What? It is exactly mac id that is used for wifi location services. You are confusing IP address location with wifi location service. IP address location is not even CLOSE to being accurate enough for this kind of usage.

I don't know where you got the idea that is based on IP address, but it is wrong.
BTW: If you think this is complicated you should see the complexity involved with satellite GPS. Much more complex than wifi location services, which pretty much is a brute-force-collected database of GPS coordinates matched to mac id. Not very complicated actually. Certainly not when compared to the physics, both classical and quantum, that goes into satellite GPS.
Of course, I know that, it has to be tethered. Didn't want to make title of thread too long ;-). Nutting misleading though. I explained it right.

It's even said a lot more people are figuring this out and opting for the lower priced wifi version since most people have phones and most of those phones are gps enabled. Just saying ;-). Good info you posted Tinman, I learn something new everyday.
