Phone Tracker

Ein Stingray scheint das Äquivalent zum IMSI-Catcher zu sein:

Stingrays are designed to locate a mobile phone even when it’s not being used to make a call.(…) A stingray works by mimicking a cellphone tower, getting a phone to connect to it and measuring signals from the phone. It lets the stingray operator “ping,” or send a signal to, a phone and locate it as long as it is powered on, according to documents reviewed by the Journal. The device has various uses, including helping police locate suspects and aiding search-and-rescue teams in finding people lost in remote areas or buried in rubble after an accident.
