Campus mobile phone blocking solution

1 Market demand analysis of campus mobile phone shielding project

1.1 Shielding of teaching areas during teaching management

As mobile phones become more and more popular, the current situation of students using mobile phones has even reached the point where even primary school students are equipped with a large number of mobile phones, and the proportion of middle schools and high schools is even greater. At present, although various schools have already expressly stipulated that teachers are absolutely not allowed to use mobile phones during class, and students are also required to turn off their mobile phones or set their mobile phones to vibrate state, due to students' self-discipline, consciousness and other issues have always been a problem for daily teaching in schools. Management brings constant trouble! For example: There will always be some students who forget to set their mobile phones to vibrate for some reason. A sudden call or text message during normal class, especially when some funny or prankish voices sound, disrupts the originally quiet classroom and normal teaching. interrupt. . . Some students who are unconscious in class are just because of the text messaging function of their mobile phones. If they don't want to listen to the class during class, they don't have to go to the next table to chat with each other. They can just use their mobile phones to send and receive text messages. Nowadays, mobile phones are equipped with Internet access functions, and students can frequently use their mobile phones to chat online, read novels, play games, etc. during class. The school installs and uses Weikai campus mobile phonesjammer Intelligent management systems can prevent students from excessive use of mobile phones during class, but if mobile phone signals are blocked in class, some students will say that the school infringes on students' "right to freedom of communication." From the perspective of students who frequently use mobile phones, these views seem reasonable, but if you think about it more seriously, if blocking mobile phone signals infringes on students' communication rights, then if these students use mobile phones in class or during self-study, there is a problem Have you ever thought that you are infringing on other students’ rights to receive education? Have you ever thought that you should respect the teacher’s right to teach? Whether rights or freedom, they are only relative, not absolute. Any rights or freedoms are based on respecting the rights of others. The laws of our country are also rules formulated based on the interests of the majority of people. These rules protect the rights and interests of the majority of people. If we really want to talk about infringement, it is the small number of students who use mobile phones at will regardless of the occasion that infringes on the educational rights of the vast majority of students. Some students or their parents may also point out that the school blocks mobile phone signals during class. What if there is something urgent at home that needs to be contacted or the student cannot be notified? In fact, this question is not difficult to answer. First of all, from the student's perspective, the high-sounding reason for students to use mobile phones is to facilitate contact with their parents. In fact, students are in school. As long as there is no emergency, there is no need to keep the phone on 24 hours a day. In the event of special circumstances, the school and teachers will proactively contact parents. Secondly, from the perspective of parents, just think back. Since your children were equipped with mobile phones, there have been several times so far that due to special circumstances, they had to stop studying in class and leave school immediately with just one phone call. of? Moreover, the school has installed Weikai campus mobile phonesjammer The intelligent management system does not block students' mobile phones for 24 hours in school. It only blocks students for 40 to 50 minutes in the morning and afternoon classes, and even between classes. The ten-minute break between classes will allow cell phone signals to be restored.

Weikai campus mobile phonejammer The intelligent management system has fully considered the humanized shielding of students' mobile phone signals.

1.2 The examination room will be blocked during the examination period

In recent years, due to the widespread popularity of mobile communication tools such as mobile phones, the use of mobile communication tools such as mobile phones to cheat has become a "secret weapon" for some candidates to improve their test scores. These candidates do not seek to study hard on weekdays, but want to use them during the exam. Some illegal methods, listening to some illegal vendors who leak questions, or organizations and individuals who make profits by providing answers, want to use their mobile phones as answer receiving tools or transmission tools to obtain ideal test scores through cheating, which seriously damages the Ensure the fairness and seriousness of the exam! It is a great harm to most other students who usually study hard and learn based on their true talents! In order to strictly enforce the discipline of the examination room and ensure fairness and impartiality to every reference person, we install the Weikai mobile phone shielding network intelligent management system or mobile phone signaljammer , is one of the most effective ways to prevent candidates from cheating through mobile phones and other communication tools.

1.3 Shielding of dormitory areas during night rest

According to some school administrators, many students now carry mobile phones. According to the observations and understanding of school administrators in recent years, in addition to a very small number of students using mobile phones as normal applications, most students use mobile phones to surf the Internet and chat. , play games, read novels, fall in love, and even some often have contact with some idle people in society, which has brought great harm to school education and students' growth! After the school leaders check that students sleep late, it becomes more difficult to restrain, manage and discover them while playing with their mobile phones under the quilt.

When the school installs a mobile phone signal blocking system in the dormitory area, it is generally recommended that it be turned on within two hours after the lights are turned off. The purpose is to enable our students to learn to live and develop good and healthy living habits! Go to bed early and get up early so that you will not be drowsy due to lack of sleep the next day and unable to concentrate on studying or listening to lectures.
