Nowadays, many schools will install the wifi jammer in order to prevent the occurrence of fraud. However, whether the school or the students, do not know how many meters the best use range of the wifi signal jammer in the examination room is.

Therefore, the use range of the wifi frequency jammer in the examination room is related to the product itself. As for its optimal use range, it generally refers not to the coverage of the signal, but to the range from the base station or amplifier. Within 200 meters from the base station or amplifier, the use of signal jammers in the examination room is the best. Generally, the diameter coverage of the wifi jammer device in the examination room is within 60 meters. That is equivalent to a classroom of 120 square meters. Therefore, the gap between products still exists. After installing the wifi signal blocker, you can test the effect and judge the installation plan according to the effect. Generally, at least one test room signal jammer is installed in a classroom. Because even within the optimal range of use, its ability to penetrate walls cannot be guaranteed. Therefore, in order to ensure the effect, the best way is to find a signal jammer with wall penetration capability or a larger coverage area.
