Apple patented a new method of determining the location of smartphone users on the basis of wireless systems.
The new method is less accurate compared with GPS/GLONASS, but it works without problems inside buildings and any places with Wi-Fi.
U.S. Patent 8700060 describes a system in which Apple will maintain a global database of WiFi- AP, while a smartphone or iPad, getting within range of an access point, will
suggest the user a particular localized content.
Note that this method of determination and a patent would be too obvious and common and therefore it will not be issued that is why the developers of Cupertino added a number of “chips ” such as geographical sweep of 50×50 meters, which allows you to specify the location of the customer.
