How to choose a suitable mobile phone signal jammer
Mobile phone jammer is also called mobile phone signal jammer, which forms a spherical or fan-shaped interference space according to the power of mobile phone jammer, so that the mobile phone loses communication with the base station. When the mobile phone jammer works, it can make the mobile phone within the interference range unusable, so as to achieve the purpose of mandatory prohibition.
Cell phone signal jammers can be used in various examination halls, conference rooms, gas stations, prisons and other places, and cell phone jammers in examination halls are the most common.

In a standard examination room, you only need to place a mobile phone jammer to achieve a better shielding effect. The jammer is usually installed on the podium, and the fixed installation is generally installed on both sides of the middle of the classroom.
Of course, in our promotional materials, the mobile phone signal jammer will have a theoretical interference distance, and the actual effect should be combined with the distance of the base stations around the examination room, that is, the signal strength of the examination room. If the examination room is equipped with a signal amplifier, then it is necessary to replace it with a higher power jammer.
In the ladder classroom of a university, we can consider installing mobile phone signal jammers in the front and back of the classroom to achieve better shielding effect.
