  Many schools are installing "cell phone jammers" in classrooms and dormitories. In this regard, many students expressed disgust. In fact, it is a necessary measure to eliminate mobile phone interference in the classroom and will not affect health. Installing "cell phone signal jammers" in classrooms is a costly, laborious and not very thankful thing.

  With the development of market economy and the progress of science and technology, mobile phones have become more and more common in our lives, and their functions have become more and more numerous. While mobile phones have brought us a lot of convenience, they have also caused us a lot of trouble. According to the report, “In class, students answering mobile phones, surfing the Internet, chatting QQ, and playing games on mobile phones are more serious. During exams, some students cheat on mobile phones, such as sending answers to classmates via mobile phones. Check the answers on the mobile phone, etc.". In some forums and post bars, I found that "there are many students posting online during class time." This situation has caused interference to teaching activities in the classroom. Only by eliminating such interference and maintaining normal teaching order can the quality of teaching be guaranteed and the expectations placed by students, parents and all sectors of society on the school will be met.

  The phenomenon of "playing with mobile phones in class" has turned the classroom into a meeting place for various information in the real society and cyberspace. Students in such an environment, under the impact of various information, tend to become impetuous. After installing the "mobile phone jammer", external information cannot enter, and the classroom becomes an independent space, restores its proper functions, and students can concentrate and interact with teachers in the classroom. Therefore, the "cell phone jammer" shields impetuousness and leaves quietness.

  Installing a "cell phone jammer" is not a random action. The "jammer" shielding signal is limited to the classroom, as long as you get out of the classroom, the mobile phone signal will be restored. In order to ensure that the health of students will not be affected, the school attaches great importance to product quality. The installed "jammers" are qualified products that meet the relevant national standards with electromagnetic radiation and will not affect the human body. Many schools and examination rooms are already using qualified products. It can be seen that the school has a serious attitude when doing this and is responsible to the students.

  The scope of mobile phone jammers is limited to classrooms, indicating that the school’s actions are moderate and will not harm students’ freedom of communication and freedom of expression. The exercise of any right has boundaries and cannot harm the rights of others and the public interest. The freedom of communication and expression enjoyed by citizens in accordance with the Constitution and the law is the same, and it cannot exceed its due limits. If students play with mobile phones in the classroom affects the normal teaching order, it is beyond the limits of their rights and should be restricted.

  The working principle of the mobile phone signal jammer is within a certain frequency range. The mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc. Generally speaking, the frequency emitted by the jammer interferes with the normal frequency of the mobile phone receiving the base station, making the mobile phone unable to connect with the base station, and thus unable to make calls, receive and send text messages, and surf the Internet normally.
