Confidential places refer to some key departments of government agencies, such as the printing room, secretariat, information department, confidential archives, etc., or some military units with a high level of confidentiality, confidential places, etc. These confidential places are usually installed. A certain number of frequency jammer, so what is the role of installing and using frequency jammer in secret places?

The role that frequency jammer can play is obvious, that is, to perform frequency interference on specific radio frequencies, so that electronic devices that use these radio frequency bands for wireless data transmission or wireless communication cannot perform normal transmission and reception. The communication link implements effective frequency interference, completely preventing the relevant confidential information in the confidential place from being transmitted to the outside world by wireless transmission.

Therefore, the frequency jammer provides a technical guarantee for strengthening the confidentiality work. If the secret place is leaked to the outside world, the possible wireless communication methods include but are not limited to: mobile phone data traffic, WiFi2.4G, Bluetooth, WiFi5.8G, UHF, VHF wireless data transmission, etc. frequency jammer installed in secret places will perform full-band coverage and signal interference for the above-mentioned frequency bands.

Of course, what we need to know is that the security place relies on frequency jammer to interfere with wireless signal transmission. This is only one of the measures for the security place to be used as a technical support for security work. We must not rely on the use of frequency jammer for all technical guarantees. Items, because there are many other ways and means of information leakage, so the confidential place should establish a complete and sound confidentiality system, such as a set of various security schemes, various technical guarantee products, and various security supervision measures.
