With the improvement of our living conditions, college students commonly use mobile phones or other electronic products. This situation creates many problems for school management. Students stay up late, texting on their phones, surfing the web, etc. During the day, the class yawns and the students bend over to sleep. Cell phone use in the classroom is now commonplace, and students now feel they have a right to use their cell phone in the classroom. They didn’t listen to the instructions and had to repeat them a few times because they were texting, listening to music or watching a video or movie on their phone while playing a game. Some students even receive or make voice calls in class. Many teachers buy cell phone jammer and use them in the classroom so that they can take back control of the classroom.
Mobile phones are an indispensable and important tool in our daily life. But with the widespread use of mobile phones, there are also some problems that cannot be ignored, especially in some important occasions, such as important conference rooms. When we are in a meeting, if we suddenly think of the ringing of the mobile phone, it will easily affect the meeting order in the conference room, interrupt the meeting process, cause other people’s dissatisfaction, and even make the meeting off topic. In addition, if you answer the mobile phone during the conference or frequently enter and leave the conference venue because of answering the mobile phone, it will affect everyone’s mood during the conference, and even make the conference room go in and out of noise.
In addition, mobile phones can easily become “bugs” in meeting rooms, posing a threat to the security of confidential information. With the development of science and technology, the positioning, tracking and monitoring of mobile phones has become an important reconnaissance method and intelligence source for countries around the world. As long as the mobile phone is carried in a secret place, whether it is used or turned on, it is very likely to leak secrets, cause serious harm to the unit or individual, and even to the party and the country.
