If you’re a teacher or student tired of other students chattering on their phones during class, a cell phone blocker in the classroom might be just what you need. With these devices, you can stop talking instantly, prevent students from cheating on exams, and avoid class interruptions due to cell phones ringing or buzzing. To have a simple cell phone screen that keeps students from playing with their cell phones in class, you need a very large or powerful cell phone jammer device. In fact, you can use a portable cell phone jammer similar to any regular cell phone to keep your cell phone quiet in class.

Mobile phone jammers cannot be installed at will. It is reported that the range of the mobile phone jammer to block the signal is limited to the classroom. As long as you leave the classroom, the mobile phone signal will be restored. In order to ensure that it does not affect the health of students, the school attaches great importance to product quality. The installed electromagnetic radiation conforms to national standards and does not affect the human body. Qualified products are used in many schools and examination rooms. The school is serious and responsible to students in doing so. This kind of mobile phone jammer shields the signal only in the classroom, indicating that the school activities are moderate and will not affect the communication and expression of students. The exercise of rights shall be limited and shall not harm the rights of others and the public interest. The freedom of communication and expression enjoyed by citizens is also enshrined by the Constitution and the law, and cannot exceed its due scope. If students play mobile phones in the classroom and affect the normal teaching order, they will overstep their authority and be restricted.
