The mobile phone standard currently in widespread use is our gsm global mobile communication system. GSM standard equipment occupies more than 80% of the current global mobile mobile communication equipment market. It is commonly used, but probably the most familiar with mobile phone use. Yes, calls and text messages rely on gsm to provide a stable network data type. But the gsm network is much more than we know. Powerful portable jammers are one of the guidelines that many electronics manufacturers are familiar with and are meticulously researching. Used in many areas of life, the gsm module is fitted with common access control security systems and GSM network car security systems and robots.
GSM also supports indoor coverage Outdoor antenna power can be distributed to the indoor antenna distribution system via a power distributor. This is a typical configuration method used to meet high density calling requirements in the home, which is common in shopping centers and airports. Indoor coverage can also be achieved with wireless signals throughout the building, which 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 communications and SMS services. As is known to everyone, improper use of mobile phones is serious, and the use of mobile phones in public places has a great noise impact on others. Is someone suddenly calling out loud if you bother while reading or relaxing in silence? I think so. We don't want to be disturbed when we need to be quiet.
The gsm network bandwidth is very important for the use of electronic devices. Therefore, in many places where the use of mobile phones is prohibited, interfering devices that interfere with the basic communication of mobile phones are installed. This is also known as gsm jamming.
In order to buy a Gsm scrambler, in addition to the gsm network, you 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 blocks all cell phone signals. In addition, I bought an electronic interference device, so I need to consider where to use it. portable jammer facilitate indoor and outdoor use, and desktop jammers use multiple antenna designs. As the name implies, it will be widely used not only by individuals, but also by 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 critical organizations, a powerful multi-antenna desktop jammer 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.
