A radio frequency jammer is recommended during major exams
If you take a large-scale exam, you will see a radio frequency jammer in the examination room. It can be seen that the radio frequency jammer has become a standard configuration in the school examination room, mainly to prevent candidates from using mobile phones to cheat.
We know that the current mobile phone has too many functions, which can be used to watch movies, video chat, take pictures and so on. At the same time, some people will use mobile phones to find answers on the Internet to cheat. This is a very bad thing. This phenomenon of cheating occurs.
In the examination room, when using a mobile phone to send a message, the signal must be used to send the message. If the mobile phone does not have a signal, there is no way to receive and send the message. The radio frequency jammer is a device that can prevent the mobile phone from receiving signals. When the radio frequency jammer is turned on, the mobile phone will lose contact with the base station and completely lose the signal in the shielded area.
The principle of the radio frequency jammer is that the frequency emitted by itself interferes with the normal frequency of the mobile phone receiving the base station, so that the mobile phone cannot connect to the base station, so that it cannot normally receive or make calls and surf the Internet. In recent years, the phenomenon of using mobile phones to cheat in various national examinations has occurred from time to time, seriously affecting the fairness and impartiality of the examination. For this reason, I suggest that radio frequency jammer should be equipped during large-scale exams in order to create a healthy and fair exam environment for candidates.
Wireless signal jammer reasonably controls mobile phone communication
Now is the era of the Internet, and the speed of information dissemination is very fast. Although mobile phones have many advantages, sometimes a wireless signal jammer is needed to prevent the dissemination of information, so as not to cause major losses. That's the reason to introduce the wireless signal jammer to you. With this powerful device, your private information will not be leaked, because the wireless signal jammer can block the mobile phone signal within a radius of 0-60 meters.
The wireless signal jammer is the ideal tool to control the communication of mobile phones. In general, law enforcement and the military use wireless signal jammers to prevent terrorists from using electronic bombs or disconnecting phone communications in critical situations. Even in public places, people tend to install wireless signal jammers to avoid unpleasant situations caused by cell phone signals
With the help of a wireless signal jammer, you can use it to block radio communications. Wireless signal jammers work by transmitting on the same frequency as the cell phone, thereby blocking communication between the base station and the cell phone. Therefore, if you do not want your information to be leaked, you only need to open the wireless signal jammer to ensure a relatively safe environment. It should be noted that the technical characteristics of wireless signal jammers are different, so before buying, it is necessary to determine the demand for wireless signal jammers.
