The first step is to look at the selected wifi jammer craft. High-quality wifi signal jammers are made of real materials from the housing to the internal components. The design is reasonable and scientific, fully considering the usability, durability, and actual effect of the product. If you have used or worked on a shield before, you can compare it by testing the performance and unpacking the product inside.
The second step is to choose a wifi signal jammer brand. Although there are many brands of shielding devices, there are not many brand products with real strength. By consulting professionals online, etc., you can understand the authenticity of the jammer brand.
The third step is to check and test the relevant functions of the wifi frequency jammer product. Why are you doing this? Since there are many inferior wifi jammers on the market, in order to sell at low prices, the functions of the products are often tampered with, mainly by canceling some circuits that optimize the signal, such as automatic gain control, etc. Generally, there are more than 200 hosts with complete circuits and less than 80 internal devices with low-quality mobile phone signals below the jammer. The effect of this kind of cut corners jammer is very bad, which will seriously affect the normal use of the wireless wifi bluetooth jammer.
The fourth step is to check the jammer signal for any interfering behavior. When the number of installations increases, poor quality wifi bluetooth jammers can cause very serious interference to nearby base stations. Obviously, if the mobile phone signal is full, you cannot make calls, causing serious communication interference to others. This behavior is suspected to be illegal. Of course, good quality wifi jammers also have interference problems, but at the same power, the interference of good quality high-end wifi jammer kit is several times or even dozens of times smaller than that of poor quality wifi blockers.
