Secret-related places must be equipped with a full-band shielding device from YIFALIU's blog

Mobile phone communication is an open electronic communication system. It must complete the transmission task through communication satellites. As long as there is a corresponding receiving device, it can intercept any time, any place, and anyone's call information. Mobile phones can also leak secrets in standby mode, because in standby mode, mobile phones also maintain uninterrupted signal exchange with the communication network, generating electromagnetic spectrum, which is easy to be identified, monitored and tracked. Intelligence experts bluntly said that even if the user does not use the mobile phone, he can turn on the mobile phone by remote control through a simple phone password and eavesdrop on any conversation you have. Therefore, a full-band shielding device should be installed in secret-related places. The relevant state departments have made the following regulations on the use and management of mobile phones of party and government organs and their staff:

It is strictly forbidden to talk about state secrets while using a mobile phone.

It is strictly forbidden to use mobile phones to store and transmit state secret information.

Mobile phones are not allowed to be brought into venues involving secret state meetings, places where matters involving state secrets are discussed, or the central computer room of secret-related computer systems. If you bring your mobile phone into the above places for special reasons, you should take out the battery or take shielding measures.

In important meeting places, examination rooms or other secret-related places, a full-band shielding device should be used to shield mobile phone signals to prevent mobile phone leaks.
