What impression do you have on the security measures against cheating during the college entrance examination? Are they 5g jammer and metal detectors? One place has adopted a more powerful signal shield for the gaokao, which covers the entire country.
The GPS signal jammer works by sending out its own signal on the same frequency as the GPS unit, a noisy signal that prevents it from receiving or transmitting any useful information, either in bursts of sound or a continuous wave.
As you know 4G LTE is a totally new signal of communication area. In recently market, there are little jammer can block its frequencies. Now the Perfectjammer’s new electronic device will help you to achieve the goals. Furthermore, it not only blocks the latest 4G LTE frequencies, but also jams other frequencies. Having a compact device, all signals can be block in your hands. The small and compact device is easy to carry.Like a small cell phone, you can put it into your pocket and any bags.
The Jammer’s role is to interrupt the communication link (or network) between two (or more) “partners”, when they are trying to talk with each other or deliver certain data between them. Jamming the communication link between a Drone and its Operator is a specific case out of many more; we can try to jam the communication between a cellular and the base station, between two tactical radios, between a bomb and a remote control that is used to activate it, etc.
Known as one of the most effective jammers in the world, the Russian helicopter-based radio electronic warfare system Rychag-AV is capable of protecting the entire vehicle by “blinding” all enemy warplanes and missiles within several hundred kilometers.
