The preparation work before the examination is a headache for colleges and universities. The most important thing is to prevent students from cheating through cell phones, Bluetooth headsets, walkie talkies and other scientific and technological means. During the college entrance examination every year, some candidates use their mobile phones to shoot test questions and seek answers online. This event makes invigilator teachers have to pay attention to it. In order to ensure that candidates have a good examination environment and prevent cheating by using modern communication tools, if you want to do a good job of signal interference in the examination room, you need to use a phone jammer to make a reasonable interference scheme in the school examination room.

To formulate a reasonable signal interference solution for the standardized examination room, it is necessary to formulate an appropriate signal interference solution according to the specific conditions of the examination room, such as the distance from the examination room to the base station, the signal tower, and the size of the examination room area, which will affect the effect of the phone jammer. If it is far from the signal tower and the area of the examination room does not exceed 100 square meters, small power signal jamming equipment can be used. If the classroom area is large, a single medium power signal jamming instrument or multiple low-power phone jammers can be used to ensure the jamming effect. If there is a signal tower near the examination room, in order to ensure the interference effect, it is best to use a phone jammer with higher power.

The signal interference in the examination room is a complex project. If conditions permit, it is best to formulate appropriate interference methods according to specific conditions after professional personnel arrive at the scene to survey the signals.
