Mobile jammers are installed in important places such as entrance examinations and final examinations to interfere with electronic signals around the examination room and prevent candidates from cheating. So, can a mobile jammer interfere with a classroom signal? If a teaching building needs to be disturbed, how to arrange it more reasonably?

What we need to know is that the mobile jammer has a theoretical interference range, and the interference radius is about 10-60 meters in a transparent environment., The actual effect depends on the signal strength of the site, especially how far the nearby base station is from the site. If there is a base station within 200 meters, it will be a little difficult to interfere. Secondly, obstacles such as walls will also affect the interference effect of mobile jammers.

Classrooms in primary and secondary schools are usually about 70-80 square meters. A mobile jammer in each classroom can achieve better results. It can be installed on the back wall of the classroom so that students' attention will not be affected, and the shielding effect of this position is also very good. For larger classrooms, such as the stepped classroom of the University, two mobile jammers need to be placed in each classroom, one in the front and one in the back. In order to ensure the interference effect, a mobile jammer can also be installed at intervals along the corridor of the teaching building. Finally, it should also be noted that the installation height of the mobile jammer is preferably 1.8m-2.5m from the ground.
