SDR IMSI Catcher System allows LEAs to covertly collect IMEI, IMSI of cell phones without the knowledge of the service providers and cell phone users.

Cellular Interception Solutions help law enforcement authorities to acquire, intercept, analyze and manage cellular communications such as voice, SMS, and Call Related Information (CRI) data.
Our IMSI-Catcher solution is designed to covertly collect basic identities (IMSI, IMEI) of 2G, 3G, 4G, and 5G (NSA) mobile phones working within its coverage area without the knowledge of the service providers and the phone users.
This will enable the agencies to identify the presence of the target in their area of operation. The IMSI-Catcher can also be used to selectively downgrade phones operating in the 3G/4G/5G networks to GSM operation mode. These phones can then be intercepted by Passive or Semi-Active Interception Solutions.
Variants of SDR IMSI Catcher System
Standalone Version:
The low-power SDR IMSI catcher is ideal for scenarios where target identities have to be obtained within a small coverage area. It can cover a maximum range of up to 25 meters.
Backpack Version:
The medium-power Backpack SDR IMSI catcher is ideally suited for operations where
target identities have to be obtained within a medium coverage area. It can cover a maximum range of up to 250 meters.
Vehicle Mounted Version:
The high-power vehicle-mounted SDR IMSI catcher system is used in case of
stationary or vehicle-mounted operation. This system is generally used to search for targets in cities or in open areas at a long distance.
Drone Mounted Version:
The drone-mounted SDR IMSI catcher system is used to search and track cell phones in restricted areas using commercially available drones. The system can reach up to a 15 km radius.

System Features

Network Scan
Automatically scans for all active 2G, 3G, 4G, or 5G (NSA) networks in the area to capture IMSI, IMEI, TMSI, Location of the Handset, and PLMN (Optional).
Base Station Emulation
Emulate service providers' Networks in 2G, 3G, 4G, or 5G (NSA).
