Jammers and other EW systems can be mounted on virtually any platform, including attack drones. Large systems can reach out to engage UASs at higher altitudes and greater distances. One of the most significant advantages of using electronic warfare against hostile drones is the reduced risk of collateral damage. This is particularly important when protecting urban infrastructure such as airports and government buildings. The use of EW against accessible targets also allows the defender to save long-range, but more expensive, kinetic weapons for use against more critical targets such as manned aircraft or ballistic and cruise missiles. https://www.perfectjammer.com/gps-blockers-jammers.html The system is comprised of two vehicles — one a “command node,” and the other a “sensor node.” The vehicles are outfitted with radar sensors, cameras, and radio frequency detectors and signal jammer. Once the crew is able to detect a threat, they use the jammer to disrupt the signals from the drone. While the system has been tested out on land by ground forces, Military.com reports that the Navy and Marines began testing the system on ships earlier this year. https://www.perfectjammer.com/wireless-wifi-bluetooth-jammers.html The US military has declined to confirm whether any of their drones have crashed as a result of the Russian jammers citing operational security. Despite US drones being equipped with anti-cell phone jammer technology, NBC quoted US officials stating that Russian disruption technology was “very sophisticated, proving effective even against some encrypted signals and anti-jamming receivers.” The Russians began jamming some smaller U.S. drones several weeks ago, the officials said, after a series of suspected chemical weapons attacks on civilians in rebel-held eastern Ghouta. The Russian military was concerned the U.S. military would retaliate for the attacks and began jamming the GPS systems of drones operating in the area, the officials explained. ttps://www.perfectjammer.com/all-gsm-3g-jammers-blockers.html In Russia a lot of the examination room of the university, students through the way of receiving SMS illegally obtaining answers, or simply by taking textbook will answer his accomplices in the examination room the right hand side via their mobile phones to read to them. University teachers in Russia say the practice of simply telling students to turn off their phones or to frisk them before they enter the exam has not worked. As such problems become more serious, some of Russia's higher education institutions have had to turn to the high-tech equipment developed by the elite of the country's big military companies. https://www.perfectjammer.com/all-cell-phone-jammers-blockers.html
