Enhancing Internal Security in Correctional Facilities through the Installation of Full-Band Frequency Jammers

Addressing the Issue of Unauthorized Mobile Phone Use by Inmates

Challenges in Installing Full-Band Frequency Jammers in Correctional Facilities:

Correctional facilities, such as prisons and detention centers, differ from other application scenarios due to their role in incarcerating and rehabilitating inmates. As a result, stringent identity verification measures are in place for all individuals entering these facilities. Additionally, thorough searches are conducted to ensure that no construction tools are brought in. The installation of full-band frequency jammers in correctional facilities requires time-consuming inspections, further complicating the process.

Accompanied Construction and Safety Measures:

To prevent any unforeseen incidents, technical personnel are not allowed to work independently during the installation of equipment in correctional facilities. Each individual entering a prison or detention center must be accompanied by at least one correctional officer. This measure serves multiple purposes: ensuring the safety of personnel, preventing unauthorized communication between inmates and technical staff, and assisting in the supervision of construction materials and tools.

Scheduling Constraints:

The installation of full-band frequency jammers in correctional facilities is subject to limited working hours. Unlike other workplaces where overtime is possible, the presence of correctional officers during the entire process restricts the construction time to coincide with their shifts. This constraint necessitates careful coordination and planning to ensure the efficient installation of the devices.


The installation of full-band frequency jammers in correctional facilities is a crucial step in enhancing internal security and preventing inmates from using mobile phones for unauthorized communication. However, the unique nature of correctional facilities presents challenges such as stringent identity verification, accompanied construction, and scheduling constraints. By addressing these challenges, correctional facilities can effectively strengthen their internal security measures and maintain a controlled environment for the confinement and rehabilitation of inmates.
