With the progress of society and the development of high technology, people's level is constantly improving. Now, mobile phones have generally become a living habit of adults and children, which has a more serious impact on primary and secondary school students. Playing mobile phones for a long time will damage their eyesight, and what is more serious is to neglect their studies. Therefore, mobile network jammers have been installed in schools, examination halls and prisons, which have been trusted by examination halls, schools, prisons and other units. Everyone is familiar with the mobile network jammer. Anyone who has participated in large-scale examinations should see it. It is placed at the door of the classroom, creating a fair environment for the examiners. However, many people doubt whether it will affect the signal transmission of the base station, so that there is no signal in the surrounding area.

Facing the problem of mobile network jammer, we should treat it rationally and scientifically. The working principle of mobile network jammer is to send a specific signal, shield or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or can not find network services, and also makes the mobile phone unable to receive or send text messages. In fact, mobile network jammers usually don't affect the signals of base stations. Mobile network jammers only interfere with mobile phone signals, so don't worry.

Finally, when purchasing mobile network jammers, we must choose regular manufacturers and guaranteed manufacturers to ensure the shielding effect.
