Block Cameras On Your Cell Phone Organizes Electromagnetic Waves

Delmarche Guy 2022/05/20

In order to ensure smooth signals around the campus, the operator has arranged in advance communication engineers to test the entrances and exits of each test center and the rest area for parents accompanying the test, and expand the hardware and software of nearby base stations to ensure the communication needs of parents in the test area during the test. We have done our best to keep your communication flowing, except for the signal being blocked during the exam. Every year in the college entrance examination, in order to prevent fraud in the examination, all communication signals in the examination room will be shielded. There are Block Cameras On Your Cell Phone, common mobile phone signal blockers in the test room: at the same time, there is a radio monitor outside the test room that can help to deal with electromagnetic waves in those frequency bands that the mobile phone blocker can't care about. Signal, real-time monitoring of radio wave signals of unknown origin. The working principle of the cell phone jammer used in the college entrance examination is to bury useful electromagnetic wave signals in a large number of useless signals. Under normal circumstances, when we use a mobile phone, the mobile phone is first connected to the base station of the operator, and the radio wave signals sent by both parties come and go. However, once the mobile phone signal jammer is turned on, it will "beat gongs and drums" around the mobile phone, and emit a "noise" radio wave signal that is many times more powerful than the received base station signal. The mobile phone cannot hear what the base station is talking about and cannot receive the base station normally. signal, the connection between the two is cut off. Whether making calls, texting, or various other functions, they are all paralyzed.

When we use Block Cameras On Your Cell Phone in the test room, it usually only works if it is installed near the test room. It won't work if installed far away. In addition, cell phone signal blockers in examination rooms can only block cell phone signals. Other electronic settings will not affect their normal operation. Therefore, the cell phone signal jammer in the examination room is indeed a very targeted cell phone jammer. When we buy a mobile phone signal shield for the examination room, we should pay attention to the power of the first shield should be higher, and the range of the second shield should be wider. Because the school is a large-scale examination, in such a large-scale examination room, we cannot just install a mobile phone signal shielding cover for the examination room, so that the purpose of shielding mobile phone signals cannot be achieved. Therefore, when purchasing a mobile phone signal shield in the examination room, you must pay attention to these two aspects.
