Due to various factors, such as: the location is relatively close to the base station, the local environmental signal is relatively strong. At this time, the effect of the general wifi jammer is not very obvious, and the shielding is not sufficient, and the function is relatively simple. Therefore, high-power wifi jammer will be considered at this time. High-power wifi jammers use reasonable methods to emit super-powerful shielding signals to ensure that each frequency band can be completely covered and reasonably avoid other electronic signals. It can be used in prisons, large open areas, confidential places and other places.
High-power wifi jammers will vary in design and structure, and may be much larger in appearance. Most shielding devices will choose to use external antennas, which take up a lot of space and have a long shielding distance. Of course, the shielding effect is relatively Stablize. Generally, in the classroom and during exams, the use of low-power wifi jammers can achieve the desired effect. A certain distance, but also the ability to penetrate the wall. Know which frequency bands are blocked. Generally, mobile phone signals can be blocked when leaving the factory. You can also ask manufacturers to block other frequency bands, such as: WIFI, drones, walkie-talkies, etc. These requirements can be achieved by manufacturers.
