Backpack IMSI Catcher – Advanced 4-Channel MITM Interception System for Tactical Operations
The Backpack IMSI Catcher is a next-generation 4-Channel IMSI Catcher designed for covert field intelligence, law-enforcement surveillance, and military operations. Built on advanced SDR intelligence technology, the system supports GSM/UMTS/LTE/5G interception, enabling real-time extraction and analysis of mobile subscriber identities.
With its MITM interception system, the device performs IMSI & IMEI extraction, MSISDN identification, TMSI correlation, and selective service manipulation. It integrates base station emulation (BTS) to control subscriber connectivity, while supporting silent call, downgrade (2G/3G/4G/5G), selective accept/reject, selective denial of service, and handover forcing modes for full operational flexibility.
The tactical backpack surveillance system offers up to four simultaneous channels with customizable frequency bands, covering 400 MHz to 2700 MHz and supporting B1/B3/B5/B7/B8/B20 and others depending on user requirements. Engineered for ruggedized field deployment, the system provides long-range operation (up to 150 m in urban areas) and features an autonomous power supply, high-power BTS modules, and intuitive notebook/tablet control.
Real-time visualization tools include cellular mapping, direction-finding support, and full subscriber tracking capabilities, allowing operators to identify roaming devices, map movement, and correlate identities. Combined with Wi-Fi/LAN remote console, GPS positioning, and SDR-based fast reconfiguration, this portable system provides unmatched versatility for tactical intelligence missions.
