With the rapid development of communication technology, 4G and 5G networks have become an integral part of our daily lives.
However, in certain situations, such as examination rooms, conference rooms or confidential areas, interference with mobile phone signals may cause unnecessary problems.
At present, 4G 5G mobile phone signal blockers have become a powerful tool to solve this problem.
First, the basic principles of the mobile phone signal valve 4G 5G
1, signal shielding principle
4G and 5G mobile phone signal blockers protect mobile phone signals by jamming and suppressing them by emitting electromagnetic waves at the same frequency as mobile base stations. This interference signal will cover the frequency band of the mobile phone signal in the target area, so that the mobile phone can not receive and send signals normally;
2. Technical characteristics
4G and 5G mobile signal suppressors have the characteristics of full frequency band, high power and wide coverage. It can cover multiple frequency bands such as 2G, 3G, 4G and 5G to meet the needs of different scenarios. At the same time, its power is adjustable, and the range and strength of the shield can be adjusted according to the actual situation. In addition, the interceptor also has intelligent recognition function, which can automatically identify and intercept mobile phone signals in the target area.

2, 4G/5G mobile phone signal blocker application scenarios
1. Prevent cheating in the examination room
In some exams, in order to prevent students from using mobile phones to cheat, mobile phone signal blockers are usually installed in the exam room. By blocking the mobile phone signal, it can effectively prevent the examinee from verifying the answer or passing the information through the mobile phone, so as to ensure the fairness of the exam;
2. Confidentiality of meeting rooms
In meetings involving trade secrets or sensitive information, in order to prevent participants from using mobile phones to leak information, you can set up mobile phone signal blockers in the meeting room. In this way, participants can not use mobile phones to make calls, send text messages or surf the Internet, thus ensuring the confidentiality of the content of the meeting;
3. Security of classified areas
In classified areas such as the military and government, cell phone blockers are often used to prevent outsiders from eavesdropping, clandestine photographing and other illegal activities. By blocking mobile phone signals, it can effectively prevent others from using mobile phones to engage in illegal activities and ensure the security of confidential areas.
