The currently widely used mobile phone standard is our gsm global mobile communication system. GSM standard equipment accounts for more than 80% of the current global mobile phone mobile communication equipment market. Used well, but probably the most familiar with using cell phones. Yes, calls and text messages rely on gsm to provide stable network data types. But the gsm network is much more than we know. high power jammer is one of the guidelines that many electronics manufacturers are familiar with and are studying with great care. Although used in many fields in life, gsm module has applied general access control security system and GSM network car security system and robot.
GSM also supports indoor coverage The power of outdoor antennas can be distributed to the indoor antenna distribution system via a power distributor. This is a typical setup scheme used to meet typical high density call requirements in homes at shopping centers and airports. Indoor coverage can also be achieved with wireless signals throughout the building, but this improves signal quality and reduces interference and echo.
Why do you need a jammer?
GSM is the basic network frequency band for mobile phone voice and SMS services. As is known to all, improper use of mobile phones is serious and the use of mobile phones in public places makes a great noise impact on others. Is someone suddenly calling out loud when annoying while reading or relaxing in silence? I think so. We don’t want to be disturbed when we need to be quiet.
gsm network bandwidth is very important for the use of electronic devices. Therefore, in many places where the use of mobile phones is prohibited, interference devices are installed that interfere with the basic communication of mobile phones. This is also known as gsm jamming.
In order to buy a gsm jammer , in addition to the gsm network, you need to shield the signal type, such as whether you need to shield the 3G, 4G network band. In this way, you can buy a cell phone blocker that shields all cell phone signals. In addition, since you have purchased an electronic interference device, you need to consider where you will use it. Portable jammers facilitate indoor and outdoor use, while desktop jammers use multiple antenna designs. As its name implies, it will be widely used not only in individuals but also in prisons, courts and other large venues. It has a wide interference range and more types of signal shielding.
Personally, I recommend the 8-antenna portable gsm scrambler. It is sufficient for your needs and provides a quiet reading environment whenever you need to be quiet. For businesses and important organizations, powerful multi-antenna desktop jammers will be a better choice for you. This is very noticeable in terms of function and interference radius and is considered sufficient for large scale applications.
