With the development of science and technology, I believe everyone is familiar with Signal Jammer (commonly known as mobile phone shield). In the college entrance examination or various examinations in the school, the frequency of the shield is increasing. Therefore, the use of mobile phones during the exam is unfair to others, so there is a signal jammer. So, how to install signal jamming function in school to achieve the best effect?

For better shielding, put the Signal Jammer on a chair or table. Of course, it can also be directly placed on the ground, which depends on the strength of the radio signal on site. It can also be placed in the front and back of the classroom, which can better ensure shielding. If you only want to put a shield on the podium in front of the classroom and are worried that it is difficult to protect the area behind the classroom, you can put it in the middle of the classroom. At this time, the length of both sides of the shield required by the signal jammer is shorter, and the effect will be better.

If the signal jammer is used in the classroom for a long time. We need to fix the Signal Jammer in the classroom. The first is to put it higher, 2.5m-3m or even higher. On the one hand, it is about better shielding, on the other hand, it is to prevent being damaged by some naughty students, so it must be high enough. You'd better put it in the middle of the back of the classroom.

In addition, if the number of signal jammers is too large, it is necessary to switch on and off uniformly. The shield lines in each classroom are connected together. When they are used and closed, they are uniformly controlled by the school and can be opened and closed uniformly, which saves time and effort. Thus, the trouble that each classroom needs to be opened everywhere is avoided.
