Test the effect of wireless signal jammer

　　When American College Test uses a wireless signal jammer, the installation is a very important content. If the control is appropriate, it is basically certain that there will be a very good shielding effect. However, if there is a problem in the deployment and control, it is easy to have a blind corner of the shielding, so the effect of the shielding is greatly reduced.

　　Speaking of which, the reason why American College Test installed a wireless signal blocker is actually to block the signal of the mobile phone, so at this time, we only need to use the mobile phone for testing and there is no problem. However, in this process, there are some points that need to be paid attention to. First of all, we need to prepare enough mobile phones. Because the frequency of each

　　mobile phone is slightly different nowadays, the inspection can only be completed by ensuring that each type of mobile phone is blocked. Secondly, the mobile phones we use should also be comprehensive in terms of operators. The mobile phones we will use every day, AT&T, Verizon, and T-Mobile mobile phones should be prepared for testing to ensure that everything is safe.

　　In addition to preparing a sufficient number of mobile phones, we also need professional help when testing. Many people may think that the detection is to see if the mobile phone has a signal, and we can do it ourselves. However, after the wireless signal jammer is installed, the impact range is very large, and many parts may have blind spots for shielding. It is obviously unrealistic for us to try one by one. professional staff will know which corners are prone to blocking dead corners because of their rich experience, so that they can effectively prevent loopholes during detection, and the overall efficiency will be higher.

　　Finally, when you are testing the mobile phone of the mobile signal jammer, don't think that the shielding has been completed when the number of mobile phone signals has completely disappeared. In fact, in many cases, the mobile phone has no signal grid number but still can transmit information. At this time, it is best to take intermittent calls to determine whether the phone is really blocked.
