Here you can find your own jammer

The most widely used mobile phone standard is our GSM global system for mobile communications. GSM standard equipment accounts for more than 80% of the current global mobile phone mobile communication equipment market. Although commonly used, you may be most familiar with the use of mobile phones. Yes, calls and text messages rely on GSM to provide stable network data types. But there is much more to the GSM network than we know. Powerful mobile radio uav jammer are one of the guidelines that many electronic manufacturers are familiar with and carefully studied. GSM modules are used in many areas of life, generally used in access control security systems, as well as GSM network car security systems and robots.
GSM also supports indoor coverage. Outdoor antenna power can be distributed to indoor antenna distribution systems through a power divider. This is a typical setup that meets the requirements of high-density calls within the home, and is common in shopping malls and airports. Indoor coverage can also be achieved through wireless signals throughout the building, thereby improving signal quality and reducing interference and echo.
Why do you need a jammer?
GSM is the basic network frequency band for mobile voice communications and SMS services. As we all know, improper use of mobile phones is a serious phenomenon, and using mobile phones in public places will bring a lot of noise to others. When you are reading or relaxing quietly, someone suddenly calls loudly to disturb you? I think so. When we need quiet, we don't want to be disturbed.
The GSM network band is very important for the use of electronic devices. Therefore, in many places where mobile phones are prohibited, jammers are installed to interfere with the basic communication of mobile phones. This is also called GSM interference.
Buying a GSM jammer requires shielding signal types, such as whether you need to shield 3G and 4G network bands in addition to the GSM network. In this way, you can buy a mobile phone jammer, which will block all mobile phone signals. In addition, since you have purchased an electronic jammer, you need to consider where to use it. Portable jammers are convenient for indoor and outdoor use, while desktop jammers use a multi-antenna design. As the name suggests, not only personal use will be more extensive, but also large places such as prisons and courts will use it, with a wider interference range and more types of signal shielding.
I personally recommend an 8-antenna portable GSM jammer to meet your needs. It is enough to provide a quiet reading environment when you need quiet. For enterprises and important institutions, a powerful multi-antenna desktop jammer would be your better choice. This is important in terms of functionality and interference radius, and is sufficient for large-scale applications.
