SESP Jamming

SESP develops and manufactures the most effective
and reliable radio frequency jammers in the world.

Prison Facilities

The illegal use of cellular phones in prison facilities is a growing problem. With the use of cellular phones, prisoners are able to continue their illicit activities from within the confines of their cells. They are also more able to coordinate the planning of inmate riots and escapes.

SESP specializes in facility-wide jamming systems which completely eliminate the possibility of mobile phone communication by inmates. The company’s high-power systems have been approved and deployed by prison authorities in several very large prison facilities in Europe, Central America, the Caribbean and other regions.
