High quality gsm signal jammer from dojammer's blog

The most widely used mobile phone standard at present is the popular asm global mobile communication system. GSM standard equipment accounts for more than 80% of the current global cellular mobile communication technology equipment sales market. It is widely used. Maybe you know about mobile phone apps. That's right, phone calls and text messages use ASM to provide stable network basic data types. However, the asm network is far more than what everyone is familiar with. The asm control module is one of the aspects that many electronic device manufacturers understand and analyze carefully. It is used in many aspects of daily life, but people don’t understand it. Common key management security systems and GSM network vehicle security systems and intelligent robots have used ASM control modules.

GSM also supports indoor coverage, and the efficiency of the TV antenna can be allocated to the indoor antenna distribution system through a power splitter. This is also a very typical configuration solution to achieve high-density call requirements in homes, which is common in shopping malls and airports. Covering the room can also be done based on the network signal within the building, but this can enhance the signal quality and reduce interference and echo.

Why do you have to install a jammer?

First of all, GSM is the basic frequency band used for mobile phone voice communications and SMS services. As we all know, the irrational use of mobile phones is obvious, and using mobile phones in public places will cause greater harm to others. You can imagine that if you are reading in silence and relaxing, you suddenly feel a little nervous. How annoying is it when someone has already made a phone call? I agree, we don't like to be disturbed when we have to be quiet.

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

When buying an asm jammer, we must understand our requirements. For example, in addition to the ASM network, we must also block data signal types, 3G and 4G network frequency bands. According to these methods, we can purchase a mobile phone jammer that blocks all signals. In addition, when we order electronic jamming equipment, we need to consider the area where we use it. Portable jammers can be used indoors and outdoors, while desktop all-in-one jammers use a variety of antenna designs. To put it bluntly, they will have a wider range of uses, not only suitable for thousands of people, but also widely used in prisons. , courts, schools and other more places because they have a wider interference radius and more types of signal shielding.

For my application, I recommend using a 4-wire antenna portable ASM jammer. It can meet your needs and give you a calm environment for reading, no matter how quiet you need it to be. For enterprises or key institutions, the fully functional multi-antenna surface jammer will be your best choice. It is very outstanding in terms of functionality and intervention radius, and is expected to be used on a large scale. .
