Can radio jamming equipment be used to prevent eavesdropping?

In some important confidential meetings or meetings that focus on privacy, people are very worried that the conversations of the people present will be maliciously eavesdropped. Therefore, some people want to prevent eavesdropping by installing radio jamming equipment. Then radio jamming equipment can really be used to prevent eavesdropping. Eavesdropping?

Applying radio jamming equipment to anti-eavesdropping sites requires analysis from eavesdropping methods or types of eavesdropping equipment. At present, there are two most common methods of eavesdropping. The first method is: a pickup is installed on the site in advance, and the pickup transmits the voice content of the scene to the remote receiver through the data transmission module in the device. If the data transmission is in the form of wireless communication, then our wireless signal radio jamming equipment can fully play a role in effectively preventing these voice content or data from being transmitted to the outside world. If the data transmission is through the wired cable, the wireless signal radio jamming equipment will not work, and cannot cut off the transmission link between the pickup and the receiver.

The second way is: the eavesdropper uses a high-precision audio receiving and amplifying device. It does not need to install a pickup in advance on the site, nor does it need to receive the on-site voice data through wireless reception. It only needs to be within a certain distance from the site. Just use it. So in this case, our radio jamming equipment can't interfere with it effectively.

In general, radio jamming equipment can be used in anti-eavesdropping scenarios, mainly for eavesdropping devices that use wireless data signal transmission. If there is no wireless signal transmission in the eavesdropping path, the radio jamming equipment will naturally not work.

Finally, it is added that there is a not very common way of eavesdropping, that is, the recording of the eavesdropping content is stored locally, and the voice data in the memory card is periodically obtained. For this mode, the radio jamming equipment also has no preventive effect.
