First talk about what is GSM, GSM is the Global System for Mobile Communications, a digital mobile phone network standard developed by Europe. GSM uses digital modulation technology, and one of its key technologies is TDMA time division multiple access (each user occupies a frequency carrier in a certain time slot and can only receive information at a specific time).

So what is a GSM jammer. The GSM jammer is a device used for mobile communication interference. The mobile communication jammer uses frequency multiplication, frequency division, frequency hopping filtering and other technologies for the uplink and downlink channels of the mobile phone system to analyze the required shielding frequency. When the signal jammers is in In the working state, a spherical shielding space is customized according to the power of the jammer, so that the mobile phone in this space is invalid and unable to receive and call out, so as to achieve the purpose of forcibly disabling the mobile phone.

Nowadays, in people's daily life, everyone carries a mobile phone with them. Every day, people use mobile phones to make calls and send messages. In some relatively confidential offices and meeting rooms, in order to prevent information leakage, is there any good way to make their mobile phones unable to communicate? Of course, a wireless Cell Phone signal jammer can avoid this kind of problem, protect your privacy and prevent your privacy from being leaked.

In daily life, you need a jammer to protect your privacy. The high-quality GSM jammer has a full-band design, which is specially customized for special frequency bands, and has super anti-jamming function. It also has a high power output with a maximum interference of 40m (always depends on signal strength in a given area). External omnidirectional antenna, all TX frequencies only cover downlink. A DC12V charger with an on-board battery can be used in the car. At the same time it also has a good built-in cooling system to work without interruption. You can also adjust or disable any band without affecting the operation of other bands, with infrared remote control, power switch.
The GSM jammer is also very convenient to install. First, you choose the area where you need to interfere with the mobile phone signal, and place the wireless GPS signal jammer on the table or on the wall in this area. Then after installing and connecting the device, turn on the power switch. Press the power switch to work. At this time, all mobile phones on the scene were in the state of searching for the network, and the signal connection with the base station was interrupted. When installing a jammer, we need to know the purpose of the wireless signal jammer. When you use a wireless signal jammer, you can follow the method above.
Be careful when buying a GSM jammer, we have to know what we are asking for. For example, in addition to the GSM network, we must also block data signal types, 3G and 4G network frequency bands. Through these methods, we can buy a mobile phone jammer that blocks all signals. In addition, we ordered electronic interference equipment, we need to consider the area we use. Portable jammers are convenient for us to use 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 for thousands of people, but also for common use in prisons. , People's courts, colleges and other more venues, because they have a wider interference radius and more types of signal shielding. Finally, use the jammer reasonably and legally, and don't cause unnecessary trouble to others.
