Nowadays, cell phone jammers have become a widely used signal jammer. Many companies are using them, such as school dormitories, classrooms, examination rooms, offices, conference rooms, courts, prisons and other units. In this era when jammers are so popular, there are still many people who don’t know how mobile phone signal jammers work. Will it affect the normal operation of other equipment and the health of individuals?
In fact, the working method of mobile phone signal jammers is very simple. When the signal jammer is started, the signal jammer will send a specific signal to block the connection between the mobile phone and the base station, so that the mobile phone cannot receive the information sent by the base station, and the mobile phone will not be able to use applications such as: phone calls, messages, short videos, games, etc. However, it will not affect the normal operation of other devices, nor will it affect people’s health. However, some people are very disgusted with the signal jammer blocking the mobile phone signal, and want to know if there is any way to prevent the mobile phone signal jammer from blocking the mobile phone signal. Then I will share several ways to block the jammer interference signal.
In our daily life, whether we go to a strange place, we will consciously check whether there is a wireless signal around us. However, in general, there will be mobile phone signal jammers in some special occasions to interfere with the signal, causing the mobile phone to fail to operate normally. So now many users are wondering if there is a way to prevent the jammer from blocking the mobile phone signal. In this regard, we will explain to you the commonly used signal jammer cracking methods under normal circumstances.
1. Modify the network mode in the mobile phone settings. Enter the mobile phone settings, click "Network Settings", and change the network mode to "Manual Mode";
2. Manually search the network. Then enter "Network Search" and exit immediately when the words "China Mobile" or "China Unicom" appear.
3. The mobile phone reacquires the signal. In this way, the mobile phone will have a signal, but the length of the anti-shielding time depends on the quality of the mobile phone.
The above 3 methods are effective for most mobile phones. Principle: The working mode of the mobile phone is within a certain frequency range. The mobile phone is connected through the base station radio waves, and the data and sound are transmitted at a certain baud rate and modulation method. During the working process, the mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed.
This scanning speed can cause garbled interference in the mobile phone's received message signal, and the mobile phone cannot detect the normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station. The mobile phone will show phenomena such as searching for the network, no signal, and no service system.
