GPS jammers can block targets tens of kilometers

In order for the GPS jammer to work properly, it must be close enough to the signal that its team wants to jam. On the other hand, according to Perfectjammer, an independent think tank dedicated to military electronics, high-power GPS drone jammers can detect targets tens of kilometers away. Interference requires more power than detection, so the distance that Avtobaza can interfere with drones should be less than 90 miles. When the phone jammer is active, most phones will not display network signals; when the GSM jammer is off, the phone will also be active. Mobile phones use unique frequencies for talking and listening. Most cell phone jammers block one of these two frequencies, thereby indirectly blocking these two frequencies. Mobile phone jammers work in the same way as jammers that block radio communications. They work by interrupting the frequency from the mobile phone to the base station or from the base station to the mobile phone.

Can I prevent the driver from calling? A new type of jammer made by Indian engineers can turn off the driver’s phone while the driver continues to talk or text, so that the driver can make a decision. According to Smithsonian, the system uses RFID (Radio Frequency Identification) technology to determine if the driver is trying to use a mobile phone in a moving car. This triggers the handheld jammer to shut down the driver’s phone, which is more effective than the smartphone application that needs to be installed on the criminal’s phone.

The farther the drone is from the pilot and the closer it is to the jammer, the better the effect. The typical effective interference direction is about 15 to 30 degrees, protruding toward the front of the spray gun (this is also affected by the RF frequency band and jammer power). This interference weapon is also the main direction of weapon research in recent years. It has the effects of high efficiency, less accidental damage and less loss. Currently, the device can disable enemy drones and GPS weapons. The drone gun has the appearance of a rocket launcher; it is a 13-pound shoulder-mounted cannon, but it does not fire any projectiles, but it can act as a GPS jammer. The drone has an effective range of 1.25 miles, which prevents communication between the drone and the pilot and grounds it almost immediately: the only thing to do is to aim and shoot. The police also blocked the signal from the police laser gun. Please note that in some states, laser jammers are illegal. Although the emphasis on information rejection has long been a feature of PLA doctrine, the display of this scrambling unit shows that the PLA’s efforts to reject information in multiple areas are aimed at disrupting US communications on land, air, and sea.
