Cell tower triangulation is the method of tracking a phone’s location by using multiple towers. It is similar to GPS tracking in many ways. It works by measuring the amount of time by which a signal delays in returning back to the towers from the phone. This delay is then calculated in terms of the distance and gives an accurate location of the phone. Detecting the tower’s antenna from which the signal bounced off can help to further refine the location. When used congruently with multiple towers, it gives a more specific location of the phone.
The cell tower triangulation data can also be used forensically to achieve a number of objectives, such as for criminal location verifications, in intelligence, alibi confirmation, etc.
