How does a mobile phone signal blocker block mobile phone signals?
In our daily life, we sometimes go to some areas where cell phone blockers are installed. At this time, we will find that there will be no service signal on the mobile phone, and the mobile phone has no service, but it has no effect on other communication devices. Just when the signal blocking device was just put into use, some friends still don’t know how their mobile phone signal blockers block mobile phone signals. Next, the mobile phone signal blocker manufacturer will explain this knowledge point to everyone.
At this stage, there are two ways to affect mobile phone data signals:
1. The first method is the same principle as the fiber optic network TV playback. That is, put the mobile phone in a special pocket, which is woven with copper wire and can well isolate the network data signal transmitted from the outside. The network signal is well blocked and cannot enter the pocket. The mobile phone will not be able to receive external signals at all. At this time, the mobile phone has been completely blocked.
2. The second way is that when we go to an area where information security needs to be paid attention to, the mobile phone will suddenly have no signal.
Now let the mobile phone signal jammer manufacturer tell you how to use the signal jammer: the mobile phone signal jammer will send out a radio wave with a frequency similar to that of the mobile phone signal to interfere with it. The interference signal it sends will directly block the signal normally received by the mobile phone. This will cause the mobile phone to fail to recognize the normal signal, and the mobile phone will display no service, poor signal, etc. At present, in the market, mobile phone signal jammers work in the second way. In fact, the basic concept is so simple, but it is illegal to use this frequency band without permission, and it is not easy to cause economic losses, but now schools have gradually used these to prevent it.
Working principle of mobile phone signal jammer: What is the specific principle of damaging mobile phone signal reduction? When the mobile phone receives the signal, the mobile phone first sends the login information to the base station. After the mobile phone successfully logs in to the base station, the base station can provide assistance to the mobile phone. At this time, the transmission of data between the mobile phone and the base station is also through electromagnetic waves. The transmission of electromagnetic waves is through a certain serial port baud rate. As long as this electromagnetic wave is affected, the power of the mobile phone signal can be affected. According to this communication principle, under the premise of operation, the data in the mobile phone signal jammer should output a high-quality wireless channel scanner at a certain speed. The scanning speed will affect the data signal of the mobile phone receiving protocol type. The mobile phone cannot detect the traditional data information transmitted by the base station, so that the mobile phone cannot establish contact with the base station. The mobile phone mainly manifests itself in website search, poor signal, mobile phone no service and other systems.
During operation, the mobile phone signal blocker should be adjusted to high-end according to the development trend of the low-power scanner. The scanning speed will affect the error code in the data signal of the mobile phone receiving protocol type. The mobile phone cannot detect the traditional data information transmitted by the base station, so that the mobile phone cannot establish contact with the base station, so as to ensure the effect of shielding the mobile phone data signal.
