Jammers can be used to jam multiple signal types

Have you ever used a remote control to open a car, but it has not been opened? Yes, you may be out of power, but it may also be that you are near a police station, military camp or other specially protected place. At that time, you may not understand why this happened, but the answer is simple: frequency suppressor.

A frequency jammer is a device that can be changed from the size of a piston to the size of a housing. Its purpose is very simple: to interrupt communication. Today, obtaining one of these devices is not too complicated, but the other thing is the legality of its use. Let us understand in more detail how they work and why they are prohibited.

What are inhibitors and their mode of action? Frequency portable jammer  have a very clear and simple goal: to prevent communication on certain frequencies. However, since it is not easy to prevent the device from communicating with other devices, the solution to prevent this type of information transmission is very simple, similar to a DDoS attack: introducing noise at a specified frequency, useless information soaks the tape to prevent arrival Real information.

Inhibitors can be used to interfere with various types of communications or devices from cellular networks, radar, Bluetooth, GPS, infrared, etc. Despite their wide range of uses, all inhibitors are very simple. They are based on a circuit with an oscillator that generates a signal, a noise generator, an amplifier stage to provide enough power for the signal, and finally one or more antennas to transmit the signal generated by the card.

As mentioned at the beginning, there are inhibitors of various sizes. From mobile phones to handbags, it always depends on the frequency (one or more) and range (from a few meters to more than one kilometer) to be scanned. Of course, if someone wants to know the origin of these devices, we will have to go back to war, especially World War II, when both sides used suppressors to disrupt enemy communications.

Why should it be banned or restricted? In the case of frequency interference, it occurs like many other advances, including technological advances: there are always people who use them improperly. Interfering transmitters may have legitimate uses, such as protecting certain buildings, such as preventing remote activation of explosives. However, in many cases, even those who use inhibitors may not use them properly even if they are not aware.

The situation in universities, for example, the use of inhibitors became popular in several universities in Spain a few years ago (Oviedo, Seville, Zaragoza or Valencia are some examples) . For what? Because the use of this technology is for the benefit of students who are unwilling to pass the pinganillos who are connected to the outside world to give test answers without touching the books, some teachers or faculty and staff are running on the middle street through frequency interference. Hindered communication with the outside world.
