With the progress of society and the development of high technology, people’s level is getting higher and higher. Now mobile phones have generally become a living habit of adults and children, and the impact is more important for elementary and middle school students. Playing with mobile phones for a long time is very important. It may affect eyesight, and more serious is the waste of schoolwork.
Mobile phone signal jammers are not unfamiliar to everyone, but everyone who has taken a large exam has seen them. They are placed at the entrance of the exam classroom. This is not malicious to block the signal. On the contrary, it is a manifestation of maintaining fairness. In order to give people a fair environment for the exam. However, many people wonder whether it will affect the signal radiation of the base station, so that there is no signal in an area.
Since the advent of mobile phone signal jammers, it has 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. In recent years, they have begun to be sold in the domestic market. The mobile phone signal jammer only interferes with the mobile phone signal, so it will not affect the mobile base station and other electronic equipment. Nowadays, many elementary and middle school students, each with a mobile phone, some are addicted to games, some are addicted to novels, etc., which are more dangerous for school exams. Baidu has all the answers. If everyone in the exam plagiarizes with their mobile phone, it will violate the exam. The purpose and significance!
We must take a rational and scientific approach to the mobile phone signal jammer. The working principle of the mobile phone signal jammer is to send out a specific signal to awaken or interfere with the signal between the mobile phone and the base station, making the mobile phone no signal or unable to find network services, and sending and receiving text messages with the mobile phone will also become garbled Therefore, the original message cannot be recognized.
In fact, signal jammers generally do not affect the signal of the base station, so don't worry, no one will think of interfering with other people's signals.
