Mobile phone jammer, an anti-cheating device active in various examination halls, plays a vital role in purifying the atmosphere of the examination hall and maintaining the fairness of the examination. Don't underestimate this jammer, it is a good helper to prevent and eliminate the phenomenon of cheating in the examination.

Now that the college entrance examination season has entered, bad schools are choosing a number of effective mobile phone interference devices to provide a strong guarantee against cheating in this year's college entrance examination.

Everyone is pursuing the good jamming effect of the mobile phone jammer. Of course, this is beyond reproach. After all, the quality of the jamming effect determines the best way to prevent cheating. What factors determine the jamming effect of the mobile phone jammer? Next, I will give you a brief introduction.

The jamming effect of the mobile phone jammer depends on the strength of the mobile phone signal at the use site. This is not only applicable to the use scenario of the examination room type, but also applicable to other scenarios. It is applicable to the strength of the mobile phone signal on the site, which depends on the distance between the surrounding base stations, and whether there is a signal amplifier installed nearby, or an indoor signal amplifier. This can be understood as the signal source that transmits the mobile phone signal. The distance between the signal source and the applicable site determines the strength of the mobile phone signal. The closer the distance is, the stronger the signal will be. This leads to the worse jamming effect of the mobile phone jammer. The farther the distance between the surrounding base stations is, the better the jamming effect of the mobile phone jammer will be.

How far is the distance from the base station to the examination room to achieve the effect of disturbing the whole classroom? If the problem is analyzed from the perspective of the manufacturer, the actual survey shows that when the base station is more than 200 meters away from the examination room, a mobile phone jammer can basically meet the interference effect of jamming the entire classroom.
