How accurate can it be without GPS or cell towers to help narrow it down. Seems like it could only use it's IP address as a tracking method.
it will look at all the WiFi stations around, and based on the MAC addresses (and mayse SSID?), it will look up the location from a company called SkyHook (I think).
in central NJ here in a townhouse development, it locates my position within 100 ft, not much worse than a GPS. yes, I know the GPS is supposed to be more accurate, but many times my Garmin cannot tell whether I am on the "cars only" turnpike or car, busses and trucks turnpike, which is about 60-100 feet away
