Mobile phone signal shielding is a kind of behavior that temporarily disappears or weakens the mobile phone signal by using a certain device or method. It is mainly used in education department examinations or state secret agencies. Today I will introduce wireless signals to you. How to use the jammer, I hope you can learn about the information related to shielding mobile phone signals through this article.
How to use the wireless signal jammer: The mobile phone signal in the school classroom is transmitted from the base station signal in the distance to the classroom through the doors and windows, so the most reasonable installation position is to choose the installation position of the wireless signal blocker in the examination room facing the base station The middle position of the wall on the side of the direction, so that the shielding effect of the shielding device can be maximized. Then determine the area where the mobile phone signal is shielded, and place the jammer on the table or wall in this area. After the installation is complete, continue to connect the power supply of the jammer and turn on the power switch.
After the wireless signal jammer device is connected, press the power switch to work directly. At this time, all mobile phones used on the site will lose the base station signal and can no longer make calls.
However, there are different opinions on how to use the wireless signal jammer. While the use of wireless signal jammers may be necessary in certain specific situations, there have been some concerns and objections to their use.
Some worry that the use of wireless signal jammers may infringe on personal freedom of communication. The use of wireless signal jammers may block people's normal mobile phone communications, including emergency calls and daily communications. This can pose a risk to the safety of individuals and the public, especially when contacting others is required in an emergency.
For educational testing occasions, some believe that other methods should be used to ensure the fairness of the test, rather than relying on blocking mobile phone signals. For example, measures such as banning mobile phones from being carried or collecting and keeping them properly can be used to prevent cheating. They argue that the best way to limit student cell phone use is through education and guidance, rather than relying on blocking devices.
For specific places such as state secret agencies, it may be necessary to use wireless signal jammers to ensure information security. However, this requires great care and professional handling to avoid interference or side effects on surrounding communication systems.
Over the years, we have produced various types of wireless signal jammers to protect confidential places and prevent information leakage.
