About positioning methods
Maps shows your location on the map using GPS, A-GPS, Wi-Fi, or network (cell ID)

based positioning.

A-GPS and other enhancements to GPS may require transferring small amounts of

data over the cellular network.


The global positioning system (GPS) is a navigation system that

uses satellites to work out where you are.


The Assisted GPS (A-GPS) network service retrieves location

information using the cellular network, and assists GPS in

calculating your current location.

Your phone is set up to use the Nokia A-GPS service, unless your

network service provider has its own A-GPS settings. To get the

assistance data to your phone, you need to be able to connect to

the internet. Your phone gets the data from the service only when



Wi-Fi positioning improves positioning accuracy when GPS signals

are not available, especially when you are indoors or between tall


Cell ID

With network (cell ID) based positioning, Maps locates you

through the cellular system your phone is currently connected to.

The availability and quality of GPS signals may be affected by your location, satellite

positions, buildings, natural obstacles, weather conditions, and adjustments to GPS

satellites made by the United States government. GPS signals may not be available

inside buildings or underground.

Do not use GPS for precise location measurement, and never rely solely on the

location info provided by GPS and cellular networks.
