WiFi Jammer

  The mobile phone signal jammer in the examination room is used in different occasions, and the shielding range will be different. This is not only related to the frequency band that can be shielded by itself, but also has a great relationship with the surrounding environment. If there are obstructions, walls, etc. around, or things like amplifiers that boost the cell phone signal, then the installation is not the same as in an empty classroom. When installing, pay attention to the installation height and place. Cannot be installed near shields. When installing the external 88 , it is also necessary to pay attention to the connection between the antenna and the corresponding interface. Once the wrong interface is installed, it is likely to burn out the machine. It is normal for the mobile phone shield to heat up during use. It will not affect the normal use of the shield. If you are worried, you can choose a test room signal isolator with a fan. This way, the cell phone jammer won't get too hot. When installing, pay attention that there should be no AC power lines or audio lines around the test signal isolator. In order to avoid current interference, the effect of the mobile phone signal jammer is not good.

  In some places, we can always connect to the Internet at will, and at the same time keep in touch with the people around us, but in some places, we can't use the signal casually, many people have a little doubt about the role of , Such equipment meets the basic requirements of many people, because in certain fixed environments, other types of equipment should really not be accepted by us. One of the major functions of 88 is that it can shield the signal. If we are about to take the college entrance examination, then it is not difficult for you to find that we have no way to use the mobile phone at all here. This is because the mobile phone is in such an environment. There is no way for our mobile phones to connect to the signal. The reason why managers use such equipment is to prevent some bad students from turning their attention to illegal behavior. Almost every exam, we can find that the original Some students use signals to get messages, so in general, special fields really need to use it.

  With the development of science and technology, I believe that everyone is familiar with . There will be mobile phone signal GPS jammers in the college entrance examination or various exams in school. There is no doubt that the use of mobile phones during exams causes unfair treatment to others, so there is a mobile phone signal blocker.

Mobile Baidu answers are always convenient, but for others, the hard work of learning is wasted, and 88 solves this problem. Even so, some students use various methods to cheat, but as long as they are shielded according to the signal of the mobile phone, the idea of ​​cheating can be reduced from the root. Mobile phone signal blockers are also widely used in various examination rooms, courts, and cheers stand on the edge. Its main function is to use it in various test rooms to interfere with mobile phone signals to achieve fairness in the test.

  When the mobile phone has data exchange between the mobile phone and the base station, random mutation signals are generated, so that a dynamic electromagnetic field is formed around the mobile phone jammer device. This dynamic electromagnetic field signal will induce mutation interference signals, which is easy to cause malfunction of electrical equipment. Therefore, the gas station that belongs to the fire prevention area is not only strictly forbidden to use mobile phones in the station, but also it is best not to use mobile phones within two or three meters around the gas station. At the same time, gas stations should set up a clear sign of Prohibition of calling mobile phones, and widely publicize safety knowledge, so that people understand that using mobile phones in gas stations is undoubtedly walking with tigers. There have been many fires caused by the use of mobile phones across the country. A gas station in Henan caused an explosion caused by the driver's use of a mobile phone while refueling, resulting in a serious accident that killed and injured many people. There are also many fire dangers caused by mobile phones in gas stations in Shenzhen, Chongqing and other places.
