The function of the full band jammer is to form a spherical or fan-shaped interference space according to the power of the jammer, so that the mobile phone loses communication with the base station. When the mobile phone can not work in the mandatory frequency band, the purpose of jamming can not be achieved.
The full band jammer can be used in various examination rooms, conference rooms, gas stations, prisons and other places, and the full band jammer in the examination room is the most common. Candidates who have experienced the test know that the full band jammer is to ensure the fairness of the test.
What is the interference effect of the full band jammer? How to choose the appropriate full band jammer?
In a standard examination room classroom, only one full band jammer needs to be placed to achieve good interference effect. The jammer is usually placed on the podium or fixed, usually on both sides of the middle of the classroom.
Of course, in our promotional materials, the full band jammer will have a theoretical interference distance. The actual effect should be combined with the distance of the base stations around the examination room, that is, the strength of the signal strength of the examination room to feel the distance of the interference distance. If the examination room is equipped with a signal amplifier, it is necessary to change a higher-power full band jammer to achieve full coverage of the examination room.
In the stepped classroom of a university, we can consider installing a full band jammer in front of and behind the classroom to achieve better interference effect.
