Generally, radio signal shielding is only approved when important situations such as the college entrance examination occur. Moreover, from the perspective of the "control area", signal shielding in our school does not exist. According to many students, signal shielding not only covers the nearby corridors, but also seriously affects the quality of self-study. In addition, according to our tests, outside the school, near the corridor of Qinsu Building, the signals of operators are interrupted one after another. Taking China Mobile as an example, the signal is about 20dBm lower than when it is not installed, and the SINR signal-to-noise ratio has also dropped from the normal 11-15 to 3-8. The value of the signal has greatly changed the function of the Internet. We noticed that even passers-by passing by the school will send out false signals on their mobile phones. Portable WiFi jammers in the classroom should not be missed. We collected data. In order to obtain more accurate analysis data, we will next conduct in-depth communication with the three major operators.

Mary Jane had previously taken steps to prevent their use, including buying cell phone jammers, devices that cut off service. He said the device is considered illegal, but no one in the United States has been charged with owning such a device. When buying the signal jammer, he talked to nearby teachers, who were fully supportive. The jammer was older and less effective. At best, it could only block 3G signals, and students with smartphones could still use WiFi. So I bought the latest multi-function jammer.

Many people consider installing mobile jammers in schools, and the fact that many students use their phones during class has become a major problem in schools (especially high schools).

Many educators struggle to understand how to deal with electronic devices in the classroom. Some educate students about their negative effects and encourage them to regulate their use. Others highlight the possible applications of mobile devices in the classroom. However, many simply try to ban everything. One principal in British Columbia took the school ban to the next level by installing a cell phone signal jammer. There was just one problem. The device was illegal in Canada. The principal ordered the Chinese device online, but some angry students soon found out and told him that he was breaking the law. So much for the idea. Now, he is still unseemly, but for some students, the use of mobile phones in school seems to be some kind of civil rights issue.
