Nowadays, almost every student in the school has his own mobile phone. To make matters worse, mobile phones have become a "weapon" for many students and teachers. You will find that during the lecture, most students use their mobile phones to access the Internet. Many students tend to listen to music and play video games in the classroom. Sudden ringing of mobile phones during class in the classroom is usually distracting. To make matters worse, it helps some students cheat on their mobile phones...a new phenomenon, "Internet harassment" is text messages and social networks when students need to pay. Torture others. Recently, a mobile cell phone jammer is very popular on the Internet, so how do you choose a signal jammer that suits you?
Many frequency bands and wide range make our first choice. The desktop shielded signal has 16 antennas and is suitable for multiple frequency bands, so it can block all signals of VHF UHF GPS WiFi LoJack RF and all 2G3G4G mobile phone functions. Therefore, you can use an optional button to turn on one or more desired signal bands and then turn off other groups so that you can call jammers, GPS jammers, WiFi/Bluetooth jammers, UHF/VHF jammers or remote control jammers . Secondly, due to its strong anti-interference ability and high signal strength, it can reach 40 meters, which can basically meet the needs of daily use. During this time, the interference distance can be calculated according to the actual situation. Third, after the desktop design is stable, the internal cooling fan will have a good cooling system, and the signal shield can continue to be used. It can also be used directly on the car charger. Importantly, you can also use this interference to customize the desired frequency band. This is equivalent to a mobile phone jammer that can shield many signal bands.
