Cell Phone Location Tracking

HOW IS A CELL PHONE’S LOCATION IDENTIFIED? A cell phone’s location can be detected through cell site location information (CSLI) or global positioning system (GPS) data. CSLI refers to the information collected as a cell phone identifies its location to nearby cell towers. CSLI from nearby cell towers can indicate a cell phone’s approximate location. With information from multiple cell towers, a technique called “triangulation” is used to locate a cell phone with greater precision. Cell phone location information can be “historical” or “prospective.”
