A portable jammer is a device that emits electronic signals to interfere with the normal operation of wireless communication equipment. These devices are typically used to block the transmission of wireless signals in certain areas, such as in confidential meetings, government agencies, or secure areas.
The working principle of these devices is to emit some interference signals, which are the same or close to the frequency used by wireless communication devices, so that the devices cannot operate normally. Such devices can be used to prevent others from listening to or tracking the signals of wireless communication devices, but can also affect the communication devices of other people around them.
