DTT 2G (GSM) IMSI/IMEI/TMSI catcher
DTT 2G IMSI/IMEI catcher is an advanced IMSI/IMEI catcher system that is designed to detect presence of GSM handsets in the place of interest. As indicated on the tab Operating principle, the entire system is based on a laptop and a smart compact BTS.
DTT 2G IMSI/IMEI catcher is an active system and as such, it forces GSM phones in its vicinity to register to it.
System has two basic operation modes:
1. Random (all handsets);
2. IMSI or/and IMEI (only targets).
The system operates invisibly, so that the mobile station subscriber is unable to detect it. The system does not interfere with the external mobile GSM networks. DTT 2G IMSI/IMEI catcher implements special sophisticated algorithms in order to avoid the need to transmit high power to force GSM phones to make the hand over from the real GSM network to the system’s compact BTS. By utilizing this unique algorithm, even GSM phones located very close to the real BTS and relatively far away from the 2G catcher will be forced to make a handover into the 2G catcher and by that, system effective range is extended compared to other active solutions.
DTT 2G catcher supports multiple GSM operators and can be easily upgraded to the full System of Active Interception (SAI)
Application DTT 2G IMSI / IMEI catcher:
IMSI/IMEI catching – the system detects identities of all GSM phones within it’s effective range.
Selective jamming of communication – the system operator can block communication of GSM phones defined as targets.
Presence verification ‐ the system detects and select targets of interest (according to IMSI/IMEI identifications) from the total number of subscribers located within operational area of the system.
Data Analysis / Target Correlation ‐ allows the system to detect identities of mobile phones (IMSI/IMEI) which belong to particular targets.
Direction Finding Support – the system forces target’s phone to get into transmit mode (without any visible mark) so that DF / Homing systems can track the transmission direction to identify the target mobile.
Virtual Privet Network – mobile phones connected to the system can communicate with each other, even without GSM coverage whatsoever in the region. This option requires a special firmware.
Based on the above capabilities, the 2G IMSI CATCHER can support variety of operational needs such as:
Detection of identities of all GSM mobile phones in the areas of interest;
Identifying of mobile phones which belong to particular targets;
Selective jamming of GSM phones in restricted areas (prisons, embassies, etc);
Presence detection of targets in specific area of interest (border crossing, airports, public areas);
Communication support of emergency forces in disaster areas (VPN);
Detect location of hidden mobiles (prisons, classified places);
The system can operate with variety of power sources such as AC supply, batteries, car supply etc and by that, it can be installed and operated in many types of applications and environments (fixed installation, remote control configuration, transportable, vehicular, man pack).
The IMSI catcher operate only with IMSI, IMEI and TMSI
