During the National Day holiday, full-band frequency jammers were installed on the walls of each dormitory building in Doumen No. 1 Middle School. At the same time, card phones were installed in each dormitory. It seems that the school will restrict students from using mobile phones after the festival. Friends of Douyi, the good times are over." The day before yesterday, the person in charge of the school said that it is indeed necessary to restrict the use of mobile phones by students after the festival.

Restricting students' use of mobile phones is worthy of affirmation, whether it is to reduce the interference of mobile phones on students' learning, improve the quality of students' learning, or facilitate school management. Card phones are installed in each dormitory, so you don't have to worry about parents not being able to find students and students not being able to make calls. Judging from the students' reactions, although some students thought that "the good times are over", some students also expressed their support.

While affirming the school's approach, we have to listen to different voices. Cell phone signals can be shielded with a full-band jammer, but students' right to speak cannot be shielded. The school has installed full-band jammers on the walls of each dormitory building, which can be seen as the school's restrictions on students' mobile phone behavior, speaking on behalf of the school. Some students agree, which is a voice, and some students have opinions, which is also a voice. After the school speaks out, it is good at listening to the voices of the students, so that the voices of support and opposition can be exported, so that the full-band jammer will not become the "housekeeper" of some students and the "thorn in the eyes" of others.

Let the students express their opinions smoothly, absorb the reasonable ones, and reject the unreasonable ones, so that the full-band frequency jammer can be accepted by both schools and students, which is conducive to the full-band jammer to play a better role. After the school fully discusses with the students and reaches a consensus, the situation of students avoiding the full-band frequency jammer to find the signal can be greatly reduced. If students avoid the range of full-band jammers and look for signals everywhere, it will not only affect the management of the school, but also bring hidden dangers to the safety of students. Shielding the signal has brought about other bigger problems, including security issues, and it seems that the gain outweighs the gain.

In the management and use of full-band frequency jammers, schools and students can jointly explore. For example, the full-band wifi jammer does not have to be shielded 24 hours a day, it is enough to shield it during certain periods of time, and it can be considered to synchronize with the power outage time and allow students to rest on time. It is not impossible to give students some time to freely use mobile phones to socialize. The role of the full-band frequency jammer is to control the time of free communication without completely cutting off the free communication channel.

Middle school students already have a certain degree of self-control and thinking. School education, in addition to teaching students the knowledge required for examinations, should also teach students the concept of democracy, the awareness of participation, and the observance of rules. Someone says, the disposition of classmaster is the disposition of class. By extension, the character of the school is the character of the students. In the handling of controversial matters, the school's approach will become a model for students to behave in the future, and their behavior will carry the shadow of the school. Every move of the school should take into account that students will copy and copy. In this sense, using a full-band jammer to communicate with students cannot simply be regarded as a trivial matter. It reflects a solution to a problem. Whether it is one-sided blocking, or a combination of sparse blocking, the consequences are very different in a single thought.
