The penetration rate of smartphones has been getting higher and higher, and the scope of applications is also getting wider and wider, ranging from small to daily consumption, and large to work applications, we have already made ourselves inseparable from it. However, on some special occasions, the function of the mobile phone should be limited, but there are still people who do not follow the regulations and still use the mobile phone recklessly. Therefore, there is a wifi jammer, which can block the signal well and weaken the function of the mobile phone,in order to maintain order due to those special occasions.
The wifi signal jammer is also called a wall-mounted smart signal detector and a wireless frequency jammer. It can generate specific electromagnetic signals and cover the GSM two frequency bands at the same time. The three main frequency bands of a CDMA frequency band limit the use of mobile phones in some specific ranges that need to be shielded, such as the range of ten to forty meters, while other ranges that do not need to be shielded will not be affected. The installation of a wifi frequency jammer can prevent the environment from being disturbed by noise, and also prevent the occurrence of those leaks and crimes. More importantly, it plays an important role in maintaining the safety of the motherland and protecting people's lives and property.
So how does this kind of multi-network interference achieve full-band shielding?
Actually simple. It is to repeatedly play the interference bands corresponding to the three signals in a loop, covering the three bands at one time, and the interval of this cycle is very small, and the multi-band signal jammer 2/3/4G is covered. and wifi? It doesn't matter, the same can be done. The signal jammer has evolved again, adding the frequency bands of Bluetooth and wifi to the scanning range, so that several common communication methods in society are completely covered. Many people do not understand the difference between the three methods of Bluetooth, Wi-Fi, and mobile data. It seems that they are all wireless communication technologies. In fact, the difference between the three is mainly in the frequency band. In mobile communication technology, 2G mainly works in the 900-1700MHz band, 3G works in the 1900-2100MHz band, 4G works in the 2300-2500MHz band, and Bluetooth and WiFi work in the 2.4GHz band.
