Detailed specifications of this product are not published. Full documentation is provided only to competent authorities, together with the dossier required for licensing procedures under current regulations. Contact us directly for the document request procedure.
The communications control problem
In some areas, preventing unauthorised communications is a mandatory operational requirement — phones smuggled into prisons, or transmitting recording devices in classified meeting rooms. The device creates a signal control zone within a defined perimeter.
Legal constraints
Active jamming is a strictly regulated activity under radio frequency management in Vietnam. The device may only be supplied to and used by competent authorities, within the scope and situations permitted by law. NST provides technical documentation to support the operator’s licensing procedures.
