Cell phone jammers are familiar to everyone, but anyone who has ever taken a major exam has seen them and placed them at the entrance to the exam room. This is not a malicious signal blocking. On the contrary, this is an expression of fairness and providing a fair environment for candidates. However, most of the time, some people question whether it will affect the signal radiation of the base station, leaving an area without signal.

With the advancement of society and the development of high technology, people's standards are getting higher and higher. Nowadays, mobile phones have become a lifestyle habit for adults and children. For elementary and middle school students, influencing what they say is more important. Playing with mobile phones for a long time may affect their vision, and more seriously, it may ignore their studies.

For as long as cell phone jammers have been around, they've been trusted by exam rooms, schools, prisons and other institutions. In fact, mobile phone signal jammers are no longer a new gadget abroad, and have begun to be sold in the domestic market in recent years. Cell phone signal blockers only interfere with lower cell phone signals and therefore do not affect mobile base stations and other electronic devices. Nowadays, many primary and secondary school students hold mobile phones, some are immersed in games, some are immersed in novels, etc. It's even more risky for school exams. Baidu has all the answers. Assuming that everyone uses their mobile phones to plagiarize during the exam, it violates the purpose and meaning of the exam!

Faced with mobile phone signal blocking, we should look at it rationally and scientifically. The working principle of a mobile phone signal blocker is to emit a specific signal to wake up, block or disturb the signal connecting the mobile phone and the base station, so that the mobile phone has no signal or cannot find network services, and the text messages sent and received by the mobile phone will become garbled, thus The original text message cannot be recognized.

In fact, signal blockers generally do not affect the base station's signal, so there is no need to worry and no one will think about disturbing other people's signals.
