Description

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 if the person who uses the inhibitor does not understand it, its use may not be appropriate. 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 students who do not want 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 , Hindering communication with the outside world.

The GPS jammer itself is usually a small, independent frequency transmitter that can send out interference signals within ten meters of the top five within a certain range. These devices are usually connected to cigarette lighters or USB/charging ports, and require little power. Although GPS jammers are illegal in most areas, they can be purchased online and in a variety of styles, such as B. Wi-Fi jammers, Bluetooth jammers, remote jammers, or drone jammers. GPS jammers may cause minor interference, such as signal loss, but may also pose a significant public safety risk. For example, GPS jammers cannot distinguish communication types, nor can they stop incoming or outgoing calls from emergency personnel. In addition, these devices can not only block calls, but also interfere with all communications over a wide frequency range.

The radio frequency part is the heart of the mobile jammer, because the output of the radio frequency part interacts with the mobile phone. The radio frequency range is mainly divided into three parts: voltage controlled oscillator, power amplifier and antenna. The voltage controlled oscillator is very important in the HF range and is a device. The radio frequency part generates radio frequency signals that interact with the mobile phone.

After all, it is local. Different environmental impacts are also different. The fault area of ​​the open area is larger than the area with many buildings. Therefore, the measured interference radius is usually better than the actual range. Because the test is in an open place. Because the signal may be blocked/interfered by the stone wall, the grating will form a Faraday cage (including “wrong” lead windows) and metal such as tin foil insulators, thereby reducing the reliability of the jammer indoors. In other words, if you use a jammer indoors, the glass may block the signal due to the wall. You may not be able to interfere with the signal in another room.
