Alleged that the iPhones / iPad has been tracking and recording the location-based data on mobile devices has been denied by Apple. Bitten apple logo company stated that it was just a bug that occurs in the location-based software that has been storing the user's location without ever automatically delete them after so long. So how do you actually know the location of the iPhone?
iPhone and iPad also has embedded technology Assisted-Global Positioning System (A-GPS) which is a refinement of GPS as a positioning satellites in the hemisphere. Advanced Positioning methods contained in A-GPS is a method of determining the most high-accuracy position detection method compared to other positions. so that A-GPS is much more efficient and effective in accessing information from the satellite because it does not need to search the data one by one from the existing 24 satellites, but A-GPS already know the target (satellite) where required or intended. Furthermore, A-GPS is a service that combines GPS systems and services GSM (Global System for Mobile Communications).
Apple and Google also through its Android also uses Wi-Fi positioning technology. This technology is the answer to a better location accuracy in urban and indoor areas, because the tall buildings and the roof of the building to get a transmission blocking GPS satellite, thus reducing the accuracy and speed of determination of the location. As is known, the GPS takes up about 10-15 minutes to get satellite transmission at the first GPS enabled, and even then depending on its location, whether in open areas or not.
Wi-Fi positioning technology will work in a way to login to the points Wi-Fi hotspots and cell phone tower near the gadget itself. For information, cell phone towers and Wi-Fi access point has a geographical location in the device when installed. The page on Wikipedia here may give an idea of how the technology Wi-Fi or Wi-Fi positioning trilateration.
Apple has been using Wi-Fi positioning technology that began to be used in IOS 4 of the companies that already have a database of Wi-Fi access points worldwide, Skyhook [http://www.skyhookwireless.com/howitworks/coverage.php].
With one or both of these technologies, the location of iPhone users / iPad quickly and accurately can know its position every time you open the Maps application which is marked with blue circles. When the circle appears large, the actual GPS / A-GPS is working and collecting other sources, either from the mobile phone towers and Wi-Fi hotspots to get the most precise location. When the site is believed by the software as an appropriate location, bright blue color with small size indicates the exact location.
