At least 68 agencies in 23 different states own StingRays.
How? They use a shoebox-sized device called a StingRay. This device (also called an IMSI catcher) mimics cell phone towers, prompting all the phones in the area to connect to it even if the phones aren’t in use.

The devices can be mounted in vehicles, drones, helicopters, and airplanes, allowing police to gain highly specific information on the location of any particular phone, down to a particular apartment complex or hotel room.
