Frequency jammers have recently appeared in the automotive and telephone markets. These small devices are used to encrypt and redirect the frequency of waves emitted by electronic devices so as not to interfere with a particular profession or reduce available destinations.
There are different types of frequency jammer for different frequency interferences. More and more theaters and hospitals are using it. Jammers prevent mobile phones from receiving radio waves and sending and receiving phone calls and text messages. If this is a way to win the respect of the artist, it is important for the hospital as certain waves can distort the results obtained using diagnostic or monitoring tools such as ECG.
Some drivers are also equipped with frequency interference transmitters, so if police or gendarmerie exceed the speed limit, they will not be found. This is prohibited by law and can result in criminal proceedings and heavy fines if inspected. Frequency portable jammer are also popular among thieves and therefore interfere with the frequency of remote shutdowns. I thought you closed the door, but you didn't. The thief does not have to enter the car before you look back.
How does frequency interference work? Frequency jammers are not suitable for picking up hands, so they do not take up space. However, this is a technical tool. It's not expensive, but it's not commercially available. The Internet and the black market are major suppliers of radio frequency interference. They record and encrypt radio waves through the antenna, making them unreadable. Some frequency jammers are long distances, but the basic model does not exceed 40 meters.
