Shielding range: the classroom of a standardized examination room is generally 60-90 square meters. Each classroom is equipped with one set.

Candidates at the corner may use the interference leak to carry out cheating. The stability of the interference effect. The final exam basically has a few days of exam time. The interference effect is unstable. In the middle of the interference effect, it is easy to cause candidates to use this time gap to cheat.

Finally, of course, while ensuring the requirements for the technical parameters of the frequency jammer, the budget is saved to the greatest extent. If you want to shield the whole building of the examination room through a high-power frequency jammer, the interference effect is unstable, and the price of the high-power examination room shielding instrument is also more expensive. For the standardized examination room, installing a small power device in each classroom is one of the preferred methods.
