Mobile jammer prevents communication with the outside world

Have you ever used a remote control to turn on a car, but it cannot be turned on? Yes, you may be out of Power , but because you are near a police station, military camp or other specially protected place, it may happen again. Maybe you didn't realize why this happened at that time, but the answer is simple: cell phone jammer. Mobile jammers range from the size of a hip flask to the size of a suitcase, and their purpose is simple: to interrupt communications. Today, it is not too complicated to obtain one of the mobile jammer devices, but another thing is the legality of its use. Let's learn more about how they work and why their use is prohibited.

The goal of cell phone jammers is very clear and simple: to block communication on certain phones. But it is not easy to block the device so that it cannot communicate with another solution to prevent traffic information is very simple and similar to a DDoS attack: indicating the frequency of noise introduced, useless information to saturate the network, Prevent the real information from not arriving.

Mobile cell phone jammers can be used to interfere with different types of communications or equipment from mobile networks, high-speed cameras, Bluetooth, GPS, infrared, etc., but despite their wide range of uses, all jammers are very simple. They are based on a circuit that has an oscillator to generate a signal, a noise generator, a gain stage to provide sufficient Power for the signal, and finally one or more antennas to transmit the signal generated by the panel.

As we mentioned initially, there are inhibitors of various sizes. From just mobile devices to things you carry with you, it always depends on the frequency (one or several) and range (from a few meters to more than one kilometer) to be scanned. Of course, if anyone wants to know the origin or beginning of these devices, we will have to go back to the war, especially World War II, where both sides used cell phone jammers to interfere with enemy communications.

Why are their use prohibited or restricted?
For cell phone suppressors, it happened like many other advances, including technological advances: there are always people who abuse it. Mobile phone jammers can have legitimate uses, such as protecting certain buildings and preventing remote activation of explosives. However, in many cases, even if the person using the jammer does not know it, the mobile cell phone jammers may be used improperly.

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? Since technology is used for students who prefer not to read books, by using earpieces connected to outsiders to help answer exams, there are several professors or faculties flying around along the middle street. , Use mobile cell phone jammers to prevent communication with the outside world.
