Cell phone signal scramblers are familiar to everyone, but everyone who has taken a major planning exam has seen them and put them at the entrance of the exam room. This is not a malicious blocking signal. On the contrary, this is a performance of maintaining fairness and providing a fair environment for candidates. However, most of the time, some people doubt whether it will affect the signal radiation of the base station, so that there is no signal in an area.
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 habit of adults and children. For elementary and middle school students, it is more important to influence what they say. Long-term use of mobile phones may affect their eyesight, and even more serious is to ignore their studies.
Since the introduction of cell phone jammer, they have always been trusted by examination rooms, schools, prisons and other units. In fact, mobile phone signal jammers are no longer a new thing in foreign countries, and have begun to be sold in the domestic market in recent years. The cell phone signal blocker only disturbs the lower cell phone signal, so it will not affect the mobile base station and other electronic equipment. Now many elementary and middle school students hold mobile phones one by one, some are addicted to games, some are addicted to novels and so on. It is even more dangerous for school exams. Baidu has all the answers. If everyone used their mobile phones to plagiarize during the exam, that would violate the purpose and meaning of the exam!
In the face of cell phone signal shielding, we should treat it rationally and scientifically. The working principle of the mobile phone signal blocker is to announce a specific signal to wake up, block or disturb the signal connected between the mobile phone and the base station, so that the mobile phone has no signal or cannot find the network service, and the mobile phone sending and receiving text messages will also become garbled Unable to recognize the original text message.
In fact, signal jammers generally do not affect the signal of the base station, so there is no need to worry, and no one will consider disturbing other people’s signals.
