As I understood it (correct me if mistaken); Wifi Positioning System has a network of routers of some sort, and when I plug in my new device, by using existing devices whose locations are known, they can locate my new router.
I have few questions about this;
How do they collect my info? Do they ask for permission? Can they use my device for determining the location of other devices? Does my router/device send any data about location or do they only use my signal power?
Secondly, if my router works in an intranet, without Internet connection, can they still locate my router? If not, can I some how use my router for GPS purposses without having any GPS devices?
This may seem of topic but, my questions are security related in a way... I want to use location services locally without an Internet connection and hopefully without sending data to other devices.
