8-band Digtal Fixed Outdoor Mobile Phone Signal Jammer System For Prison

The 8-Band Digital Prison Signal Jammer is a high-performance security device designed for controlled environments such as prisons, detention centers, and high-security government facilities to block unauthorized wireless communications. By precisely targeting eight critical frequency bands (including 2G/3G/4G/5G cellular networks, 2.4 GHz and 5 GHz Wi-Fi, Bluetooth, GPS, and UHF/VHF radio signals), it effectively suppresses the use of illegal communication tools. The system employs Direct Digital Synthesis (DDS) technology for enhanced interference efficiency and integrates a control box that connects to facility security networks via encrypted interfaces, enabling centralized control, firmware updates, and activity logging for remote operation. Equipped with programmable power settings, operators can customize the jamming radius (e.g., 100–300 meters) to match facility layouts while minimizing collateral interference. Combined with an industrial-grade rugged design (overheat protection, surge resistance, and self-diagnostic functions) and remote encrypted management, the jammer incorporates a cooling system for 24/7 stable operation. Housed in a weatherproof cabinet, it is suitable for harsh outdoor installations and can be customized to accommodate 8 modules targeting distinct frequency bands. A user-friendly interface displays real-time remote monitoring of output power, voltage, current, temperature, VSWR, and door open/close status.

To prevent unauthorized communications, law enforcement agencies deploy this mobile signal jammer in prisons, courthouses, military installations, sensitive government buildings, and similar locations. Applications include contraband cell phone suppression in prisons, tactical communication blocking during law enforcement operations, and anti-eavesdropping in secure zones. Its use requires government authorization and is widely adopted across Central and South America.
