Jammer becomes a means of maintaining order
Many educators have trouble figuring out how to use electronic devices in the classroom. Some educate students about the negative effects and encourage them to regulate their use. Others even emphasized the potential applications of mobile devices in classrooms. However, many people just try to ban everything. A principal in British Columbia raised the school’s ban to a new level by setting up cell phone jammers. There is only one problem-the device is illegal in Canada. The director had ordered Chinese equipment online, but some angry students soon discovered it and told him it was illegal.
Now, almost all students in the school have mobile phones. To make matters worse, mobile phones have become a "weapon" for many students to oppose teachers. In the lecture, most students were found to use mobile phones to surf the Internet. Many students listen to music or play video games in the classroom. It often happens that when the phone rings suddenly in class, it often causes distraction. Even worse, some students use mobile phones to help them cheat.... According to reports, a new phenomenon called "cyberbullying" shows that students share texts and social networks electronically with others, if they pay attention to class, it will torture them.
Some countries allow companies and government organizations to install portable jammer in areas where the use of mobile phones is considered public interference. In December 2004, France legalized mobile jammers used for performances in cinemas, concert halls and other places. France is completing a technology to route emergency calls to emergency calls. India has installed jammers in parliaments and some prisons. According to reports, Italian universities have adopted techniques to prevent fraud. The students took test photos with camera phones and sent them to classmates.
