1. The effective shielding rate should reach more than 99.9% in confined and narrow spaces and partially concealed places;
2. In the non-shielded area, the wifi signal jammer must ensure smooth communication;
3. After the shielding effect is achieved, it must pass the shielding on-site electromagnetic radiation safety inspection;
4. Fully retain the output redundancy of the wifi jammer device, improve the service life, and adapt to future development requirements;
5. The wifi jammer system must use centralized power supply.
6. Acts on all current public communication standard mobile phones, and does not affect the normal operation of other electronic equipment systems in the prison;
