Positioning methods
Your tablet shows your location on the map using GPS, GLONASS,
A-GPS, Wi-Fi, or network (Cell ID) based positioning.
The availability, accuracy and completeness of the location info depend
on, for example, your location, surroundings, and third party sources,
and may be limited. Location info may not be available, for example,
inside buildings or underground. For privacy info related to positioning
methods, see the Nokia Privacy Policy.
The Assisted GPS (A-GPS) network service and other similar
enhancements to GPS and Glonass retrieve location info using the
cellular network, and assists in calculating your current location.
A-GPS and other enhancements to GPS and GLONASS may require
transferring small amounts of data over the cellular network. If you
want to avoid data costs, for example when traveling, you can turn the
mobile data connection off.
Wi-Fi positioning improves positioning accuracy when satellite signals
are not available, especially when you are indoors or between tall
buildings. If you’re in a place where the use of Wi-Fi is restricted, you
can turn Wi-Fi off.
To turn a connection off, swipe in from the right of the screen, and tap
A-GPS, Wi-Fi, or network (Cell ID) based positioning.
