With the rapid development of information, electronic jammer shielding equipment has also emerged. For example, the school has installed electronic jammers mainly to prevent cheating. Many students will use communication tools to cheat. The school has banned it for many times, but some people will still take chances. Finally, we rely on electronic jammer equipment to avoid the situation that someone secretly brings mobile phones into the examination room to cheat.

Of course, the emergence of electronic jammers is not only because of these reasons, but also because of the needs of high-tech. Wireless signal shielding devices are also used in some enterprises or state secret institutions, hospitals, etc., which are very widely used.

The term "electronic jammer" is not new to many people today. In fact, electronic jammer can be regarded as a relatively large series. Its function can shield the mobile phone signal in the examination room, but it has no shielding effect on the mobile phone outside the examination room and will not be shielded to the base station; It only shields the downlink frequency transmitted by the BTS without affecting the uplink frequency, let alone the normal operation of other electronic equipment; The intensity of electromagnetic field is far lower than the national standard, which is green and has no impact on the human body. When the electronic jammer is used, it can run automatically when the power is turned on. The electronic jammers have all adopted special high-tech products to achieve the best state of isolation from the outside world. It is believed that the shielding equipment will be further and further away in the future.
