The bandwidth of the GSM network is very important for the use of electronic equipment. Therefore, in many places where the use of mobile phones is prohibited, interference devices that interfere with the basic communications of mobile phones have been installed. This is also called gsm interference. To purchase a gsm jammer, in addition to the gsm network, you also need to protect the signal type, for example, if you need to protect the 3G and 4G network frequency bands. In this way, you can buy a cell phone blocker that can block all cell phone signals. In addition, since you have already purchased an electronic jamming device, you need to determine where you will use the device. Portable jammers are convenient for indoor and outdoor use, while desktop jammers use multiple antenna designs. As the name suggests, it will be widely used not only in private houses, but also in prisons, courts and other large venues. It has a wider interference range and more kinds of signal shielding.
In order to ensure the blocking effect and long-term stable operation, a strong electromagnetic environment should be avoided. When you are not using a portable Bluetooth jammer, you need to turn off the power for a period of time. When used outdoors, waterproofing is very important. When the deterrent device is in operation, please do not disassemble the antenna, so as not to affect the shielding effect. The actual shielding range may vary depending on the location of use. The effective enclosed area is a circular area with the area as the center. The effective distance (30-40 m) of the mobile unit jammer usually refers to the indoor distance. In outdoor areas, the shielding distance can reach hundreds of meters. The effective range of the interfering device is related to environmental conditions, such as the distance from the base station and the installation location. In order not to affect the shielding effect, these factors need to be considered. The electromagnetic signal from the jammer is very weak.
There are many categories of telephone jammers. It can block signals such as 3g and 4g. It applies to countries and regions in the world. Communications around the world are developing. Investigate the 5g signal. Currently, this signal is not popular. I believe it will occupy most of the market share. Therefore, 5 g signal interference occurs. We pursue a healthy lifestyle. The mobile phone is an excellent tool for invention, people’s work and life. Signal jammers can ensure safety. With the development of science and technology, the location, tracking and surveillance of mobile phones have become important reconnaissance methods and means. Leaving the phone in a secret place may cause serious injury. Mobile phone jammers can interfere with mobile phone communication. It will not interfere with other electronic devices. The jammer strictly abides by the quality system. An ideal and reliable wifi jammer to ensure safe production and environmental protection.
