PRISONS JAMMER

Prisons jammer

The Prison Jammer (Selective IMSI Blocker) is an advanced system designed for controlled jamming of GSM, UMTS, and LTE communications in sensitive environments. Based on active BTS infrastructure, it enables selective management of mobile network access.

Unlike conventional jammers, this system distinguishes between authorized and unauthorized devices. Authorized users (such as staff) can continue using their mobile phones normally, while unauthorized devices are automatically denied network access.

This makes it an ideal solution for prisons and correctional facilities, preventing inmates from unauthorized communication with the outside world, while allowing staff to maintain normal connectivity. It is also suitable for strategic locations such as power plants, ports, and government facilities, as well as tactical scenarios (e.g., hostage situations).

The system is available in multiple configurations, including fixed installations, vehicle-mounted units, and portable versions. The portable unit operates on internal batteries for several hours and can be easily transported or discreetly deployed in standard luggage.

• Selective blocking of GSM / UMTS / LTE communications
