Pros and cons of mobile phone signal jammer

Nowadays, with the rapid development of science and technology, traditional mobile phones are becoming more and more intelligent, and they have become an important communication tool indispensable in people’s daily work and life. Of course, the negative effects caused by mobile phones are also immeasurable. Negative impacts in special scenarios and specific times have become new leak channels and new criminal methods, posing a threat to the security of confidential information. Therefore, it is urgent to strengthen the management and standardized use of mobile phone signal blockers.

Mobile phone signal jammers are mainly used in places where no mobile phone communication is required, such as in various examinations, office premises of confidential departments, gas stations, etc. Because of their easy installation and simple use, more and more companies use signal blocker. And the equipment signal is always in a relatively static state, which will not interfere with other electrical equipment, and has played a certain role in some special places.

The mobile phone signal jammer is also called mobile communication jammer, mobile phone signal isolator, conference security device, etc.The signal jammer transmits a strong signal consistent with the frequency of the mobile phone’s downlink frequency band, and is tuned with the signal sent by the base station to the mobile phone, so that the base station sends to the mobile phone The downlink signal is deformed and cannot be recognized by the mobile phone, which interrupts the connection between the mobile phone and the base station. Simply put, its main function is to make the phone unable to use normally. Its essence is to implement electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network.

However, with the promotion of signal jammers, it has also brought some adverse effects. The wide use of signal jammers will interfere with the normal use of surrounding residents, causing residents to use mobile phones without signals. If the shielding range is shortened, there will be a lot of It is also difficult to control the blind angle and blind zone, the shielding edge distance, and the long-term coverage is wide, the power will be large, and the radiation generated will also affect the human body. Therefore, the quality of a mobile phone signal shielding device depends not only on the The effective shielding degree of mobile phone communication signals, but also whether the radiation pollution produced by it meets the national electromagnetic radiation protection standards

Especially in government agencies, once the staff of the agency accidentally leaked the content of their work, they could easily be stolen by illegal elements. This is a very dangerous thing for agencies and agencies. In order to prevent such incidents from happening, government agencies will be equipped with mobile phone signal jammers or mobile phone signal shielding cabinets to avoid leaks.
