With the popularization of wireless wifi networks, the accompanying network security has also brought more hidden dangers. The wifi jammer is developed by us through an in-depth analysis of the wireless network communication mechanism and a comprehensive comparison of electromagnetic emission suppression methods. An information security product with independent intellectual property rights, it can form an electromagnetic protection field around you, effectively prevent the leakage of secrets in safe places, and eliminate the noise and pollution generated by wireless wifi network signals.
The use of 5G mobile phones is becoming more and more common. If the 5G signal cannot be blocked during the exam, it is easy for candidates to use 5G mobile phones to cheat. So this requires an upgrade of the previous machine, what should I pay attention to when upgrading the wireless wifi blocker to 5G?
① Of course, it is the shielding frequency band of the wireless wifi signal jammer. The wireless signal jammer installed in the school is mainly to prevent candidates from cheating through various high-tech communication means. Bluetooth headsets, walkie-talkies, and other signals need to be shielded.
②Effective shielding distance. For general examination rooms, at least one wireless signal jammer should be installed in a classroom. This jammer needs to be able to block the wireless signal of the entire examination room, and it is best not to interfere with the normal life of surrounding residents. Therefore, the effective shielding distance depends on the specific situation of the examination room.
③The stability of the shielding effect must be guaranteed to be shielded throughout the examination process, and there should be no intermittent situations.
Finally, the wireless 5g wifi jammer operates in a low-pitched tone when it is working, so it will not generate noise at all, so there is no need to worry about disturbing the candidates who are taking the exam. The candidate causes bodily harm.
Wifi jammer functions and features
The wifi blocker is easy to carry with you and has good concealment. It is equipped with lithium battery. The battery can be removed and replaced. It can work for about 2 hours once fully charged. Candid photography, wireless LAN card, etc.
All wifi jammers are made of SMD and high-density integrated circuits, with advanced performance, small size, easy to carry, easy to operate, with one battery and two charges, the battery can be opened and the slide cover can be replaced, and the work is stable.
