With the development of science and technology, such inventions as mobile phones have been born to make life more convenient. After entering the high-speed information age, mobile phones have more functions. Many people use them to watch movies and chat, but some people intend to use the convenience of mobile phones to cheat in the exam. This is a very bad behavior, not to mention a behavior that is prohibited in the exam, In order to prevent and eliminate this phenomenon, it is a common means to install mobile phone jammers in the examination room. This is a device that can completely eliminate cheating.

When receiving and sending information, mobile phones need to be supported by communication signals. If mobile phones do not have signals, it is impossible to receive and send information. Mobile phone jammers can just cut off communication signals, making mobile phones completely disconnected within the interference range. This practice has been vigorously promoted in the examination room, providing better guarantee for the order of the examination room, so that examinees can get a real score. When choosing to purchase a mobile phone jammer, you must select the latest version of the jammer.

Therefore, when purchasing standardized examination room signal interference products, we must identify good brand manufacturers to ensure better interference effect and create a good examination room environment.
