Indoor Jammers

Indoor Jammers – Localized RF Signal Blocking for Controlled Environments

Phantom Technologies’ indoor jamming systems are designed to block wireless communication signals—such as cellular, Wi-Fi, and GPS—within confined indoor spaces including offices, prisons, educational institutions, and government buildings. These systems emit carefully calibrated RF interference that disrupts targeted frequency bands, ensuring secure and controlled environments.


Key Capabilities

  • Multi-Band Jamming
    Blocks cellular (2G, 3G, 4G, 5G), Wi-Fi (2.4/5 GHz), and GNSS (GPS) signals within a defined radius—typically up to tens of meters indoors.

  • Counter-Surveillance & Privacy Protection
    Prevents wireless eavesdropping, signal-based espionage, and command/control of hidden devices or spyware planted in sensitive environments.

  • Anti-Tracking (GPS Blocking)
    Interferes with GPS signals to prevent real-time location tracking, useful in secure logistics or personnel privacy management.

  • Cellular Communication Control
    Limits unauthorized phone use in areas where mobile communication is restricted, such as correctional facilities, secure offices, or meeting rooms.

  • Signal Isolation in Educational Institutions
    Reduces the risk of academic dishonesty by blocking smartphones and connected devices during exams or in restricted classrooms.

Use Cases

  • Prisons and Correctional Facilities

  • Government and Military Offices

  • Courtrooms and Interrogation Rooms

  • Exam Centers and Schools

  • Corporate Boardrooms and R&D Departments

  • Hotels, Auditoriums, and Conference Halls

  • Private Security Zones and Safe Rooms


Phantom’s Indoor Jammer Solution

Phantom’s indoor jammers are compact, discreet systems built into metal enclosures for easy installation on shelves, ceilings, or behind walls. They can be remotely activated via IR control and are optimized for localized signal disruption without interfering with adjacent areas.

Each unit is engineered to operate reliably in closed environments, ensuring high-efficiency signal blocking with minimal maintenance and maximum operational security.
