apparently, cell phone towers use triangulation to determine the location of a handset and decide if it is reasonable for the phone to be where it is based on last location and rate of travel. An example - handset apears to have moved at 800 miles per hour, suggests a spoof or clone is in operation. if a handset can do the converse, and determine that a tower is so close that it magically appeared out of thin air, or appears to be moving then the handset should not connect to the "tower" [AKA stingray] as it is probably a spoof handshake attempt. as a supplemental i have this link to add here.
