The currently widely used mobile phone standard is our gsm global mobile communication system. GSM standard equipment occupies more than 80% of the current global mobile communication equipment market. Used well, but may be the most familiar to use mobile phones. Yes, calls and text messages rely on gsm to provide stable network data types. But the gsm network is far more than what we know. Powerful mobile jammers are one of the criteria that most electronics manufacturers are familiar with and carefully researched. Although the gsm module has been used in many areas of life, it can still be used with general access control security systems and GSM network car security systems and robots.
GSM also supports indoor coverage. The Power of the outdoor antenna can be distributed to the indoor antenna distribution system through the distributor. This is a typical setup scheme to meet the typical high-density call requirements in shopping malls and airports. The wireless signal throughout the building can also achieve indoor coverage, but this can improve signal quality and reduce interference and echo.
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 gsm interference. In order to purchase a Gsm scrambler, in addition to the gsm network, you also need to shield the signal type, such as whether you need to shield the 3G and 4G network frequency bands. In this way, you can buy a cell phone blocker that can block all cell phone signals. In addition, since you have already purchased an electronic cell phone blocker device, you need to consider where to use it. Portable jammers are convenient for indoor and outdoor use, while desktop jammers use multiple antenna designs. As the name suggests, it will be widely used not only among individuals, but also in prisons, courts and other large venues. It has a wider interference range and more types of signal shielding.
Why do I need a jammer? GSM is the basic network frequency band for mobile phone voice 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 anyone yelling suddenly while reading or quietly relaxing? I agree. When we need silence, we don't want to be disturbed. I personally recommend using an 8-antenna portable gsm encryptor. It is sufficient to meet your needs and provide a quiet reading environment when you need it. For enterprises and important organizations, a Powerful multi-antenna desktop 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.
