The first step is to review the selected barrier process. The high-quality mobile phone signal jammer is made of real data from the outer shell to the internal components. The design is reasonable and scientific, fully considering the usability, durability and practical function of the product. If you have used the shield before or engaged in related work, you can test the performance and open the internal packaging of the product to compare.
The second step is to select the shielder brand. Although there are many brands of shielding devices, there are not many real powerful brand products. After online consultation with professionals, etc., you can understand the authenticity of the shield brand.
The third step is to view and test the related functions of the cell phone jammer product. Why are you doing this? Because there are many defective mobile phone signal jammers in the market, the functions of the products are often tampered with in order to sell them at a low price. The main reason is to cancel some circuits that optimize signals, such as automatic gain control. Generally, there are more than 200 hosts with intact circuits, and there are less than 80 internal devices with low-quality mobile phone signals below the k jammer. The role of this kind of cutting corners is very different, which will severely affect the normal use of mobile phone signals.
The fourth step is to check whether the jammer signal has any disturbing behavior. When the number of installations increases, the defective mobile phone signal jammer will cause severe disturbance to nearby base stations. Obviously, you cannot make a call when the mobile phone signal is full, causing severe communication disturbance to others. This behavior is suspected of being illegal. Of course, good quality mobile phone signal jammers also have interference problems, but under the same power, the interference of good quality high-end mobile phone signal jammers is several times or even dozens of times smaller than that of poor quality mobile phone signal jammers.
