Mobile phones are easily available in many parts of the world on the basis of “pay cash and no questions asked”, this creates a major problem for law enforcement as the identity of their target mobile phone is unknown. Specialised Communications is able to offer its own unique “IMSI Catcher” which can identify unknown mobile phones making it possible to subsequently use conventional LI techniques to monitor the handset or to Locate it.
