cell phone jammer

Many people have this problem. I have a question about cell phone jammer. "Yes, it is necessary to prohibit the use of mobile phones in schools. Teachers who work in the field really do this, just to keep it, I think it is very difficult. But whether to prohibit forced use, for example, I think there is a kind of Ways to do this. Install cell phone jammers in schools, but what about the law? It is up to the individual to decide whether it is legal to install such a machine?

GSM is the basic network frequency band for mobile phone voice communication and SMS services. As we all know, improper use of mobile phones is very serious, and the use of mobile phones in public places will have a great noise impact on others. Is someone yelling suddenly when you are disturbed by reading or silence? I agree. When we need to be quiet, we don't want to be disturbed. Gsm network bandwidth is very important for the use of electronic equipment. Therefore, in many places where the use of mobile phones is prohibited, interference devices that interfere with the basic communications of mobile phones have been installed. This is also called a cell phone jammer.

In order to buy a mobile phone jammer, in addition to the gsm network, you also need to shield the signal type, such as whether you need to shield the 3G, 4G network bandwidth. In this way, you can buy a cell phone blocker that can block all cell phone signals. In addition, I purchased an electronic jamming device, so I need to consider where to use it. Portable jammers are convenient for indoor and outdoor use, while desktop mobile jammers use multiple antenna designs. As the name suggests, it will be widely used not only by individuals, but also by prisons, courts and other large venues. It has a wider interference range and more types of signal shielding.

I personally recommend using a 16-antenna portable cell phone jammer. It is sufficient to meet your needs and provide a quiet reading environment when you need to be quiet. For enterprises and important organizations, a powerful multi-antenna desktop mobile phone jammer will be your better choice. In terms of functionality and interference radius, this is very obvious and is considered sufficient for large-scale applications.
