1. What is IMSI Catcher?

IMSI catcher is a hi-tech self-detective device that can be widely used for NSA, Public Security, the army, and the other confederacy agency. It is based on the BTS working principles and some relevant small-cell solutions. It is small in size, low consumption, intelligent, and has easy maintenance features.

The Stone IMSI Catcher is a multi-functional catcher which acquires GSM, UMTS, LTE, and NR cellular devices within its coverage area and extracts their cellular identities (IMEI, IMSI, and SUCI).  The unit, which can be set up in any scenario, can also detect the presence of all cellular phones in restricted areas where it is deployed and issue an alert if a predefined target device is identified.

It is also equipped with various software configurations to meet many practical needs. It can provide advanced analytics (such as Accompany Analysis, Permanent analysis, Track Analysis, and Crash Analysis ). It is easily integrated into other intelligence-gathering systems and works across all cellular makers, operating systems, and technologies such as GSM/UMTS/LTE 2G/3G/4G/5G (NSA and SA).

It supports 2G/3G/4G/5G full band scanning and collects info at a super rate. The device detects all the surrounding active mobile IMSI in silence mode and it won’t disturb standard mobile communication. The captive ratio can reach 99%.

It comes in various form factors and configurations: a highly compact unit that fits into a jacket pocket for close contact covert operations; ruggedized suitcase or backpack portable units; vehicle-mounted for flexible deployments; and fixed, rack-mounted units for long-term operations. Moreover, configurations may be customized to specific customer needs, leveraging that all system components are developed in-house. Furthermore, Stone IMSI Catcher is an all-in-one system that supports GSM, UMTS, LTE and 5G technologies, including all relevant frequency bands in multi-cells configurations.

3. IMSI Catcher Working Principle

As the stronger antenna signal makes the cellura re-select the mobile detect code BTS(IMSI Catcher), and connected, update the network, and get user IMSI. And transfer the IMSI info to the backend database and do the analysis.
