Passive cell phone blocking

Many customers call and say that I need a cell phone jammer that can shield a radius of 50 meters, an interval of 500 meters, and a radius of one kilometer. It also needs to be shielded by China Mobile, China Unicom and China Telecom. Is there a problem with the customer's request? No problem, and a specific interval requirement is also given, but can it be completed? The answer is that it is more difficult to achieve. Why is it more difficult to achieve? Isn’t the signal jammer’s parameters marked with its own shielding interval, can it be done if you put a few more sets according to this interval? In fact, it is not the case, the customer is not wrong, but they do not know the signal jammer The shielding plan is not a fixed value. How to understand it? Texin Electronics will give you an explanation.

The signal jammer scans the low-end frequency of the channel to the high-end at a certain speed during the operation process. This scanning speed can constitute garbled interference in the message signal received by the mobile phone, causing the mobile phone to fail to detect the normal microwave signal data announced from the base station , Make the mobile phone unable to establish the connection with the base station within a certain plan, to achieve the purpose of shielding the mobile phone signal.
