The location services can also use cell tower signals (triangulation) or wifi to determine location. For many cell tower networks, the pinpointing accuracy may be even greater, since directional antennae may be used on the tower, and thus the direction of the cell phones signal might be identifiable. Nokia phones simply don't share that data with an uncertified api's. Each mobile tower is the center of a circle. So this data is also what is preserved by the carrier records yeah? The way cell phone triangulation works is basically just intersection of spheres. If the phone does not have a GPS sensor, or the GPS sensor is providing a poor signal, the device will use cell tower or Wi-Fi triangulation. If a third tower is brought into play, and the phone in question is determined to be 5 miles from the (third) green tower, this diagram shows that the area of location can be estimated even more closely.

(LogOut/ For a lot of technical reasons, this is not a very accurate measurement, and the determined distance will have a reasonably significant error band. Here is how a single-tower location would work. The accuracy of network-based techniques varies, with cell identification being the least accurate (due to differential signals transposing between towers, otherwise known as "bouncing signals") and triangulation as moderately accurate, and newer "advanced forward link trilateration " [5] timing methods as the most accurate.
