The most widely used mobile phone standard currently is our gsm global system for mobile communications. GSM standard equipment accounts for more than 80% of the current global cellular mobile communication equipment market. It is widely used and maybe we are familiar with the use of mobile phones. That's right, phone calls and text messages rely on GSM to provide a stable network data type. However, there is much more to GSM networks than we know. The gsm module is one of the directions that many electronic manufacturers are familiar with and carefully researched. It is used in many aspects of life, but we don't understand it. Common access control security systems and GSM network car security systems and robots have been applied to gsm modules.

GSM also supports indoor coverage. The power of the outdoor antenna can be distributed to the indoor antenna distribution system through a power divider. This is a typical configuration used to meet high-density call requirements in homes, which is common in shopping malls and airports. Indoor coverage can also be achieved via wireless signals within buildings, but this improves signal quality and reduces interference and echo.

Why do you need a jammer?

First, GSM is the basic network band used for mobile phone voice communications and SMS services. It is known that inappropriate use of mobile phones is serious and using mobile phones in public places can cause a significant noise impact to other people. Can you imagine how annoying it would be when you are reading and relaxing in silence and suddenly someone is making a phone call? I agree. We don't like to be disturbed when we need to be quiet.

The gsm network band is very important for the use of electronic devices. Therefore, in many places where the use of mobile phones is prohibited, jamming equipment that blocks basic mobile phone communications is installed. This is what we often call GSM jammers.

When purchasing a gsm jammer, we need to understand our own needs. For example, in addition to the gsm network, we need to block the signal type and whether it is necessary to block the 3G and 4G network bands. In this way, we can buy a cell phone jammer that blocks all cell phone signals. Additionally, we purchase electronic jamming equipment and we need to consider where we use it. Portable jammers allow us to use them indoors and outdoors, while desktop signal blockers use a variety of antenna designs. As the name suggests, they will have a wider range of uses, not just for individuals but also in prisons, courthouses, schools, and other larger venues, as they have a wider interference radius and more types of signal shielding.

For personal use, I recommend a 4-antenna portable gsm jammer. It's enough to meet your needs and provide you with a quiet reading environment wherever you need to keep quiet. For a company or important organization, the powerful multi-antenna desktop jammer will be your best choice. It stands out in terms of functionality and interference radius and is considered sufficient for large-scale applications.
