In modern society, mobile phone signal jammers are often used in large-scale exams, and are also widely used in gas stations, finance, hospitals, and military centers.
As long as there is a sign prohibiting the use of mobile phones, there will generally be a mobile phone signal blocker. So how to use the mobile phone signal jammer?
What is the working principle of the cell phone signal jammer? Let's analyze it for you, which will help you better understand the cell phone signal jammer.
When using the cell phone blocker, select the area where the mobile phone signal needs to be cut off, and place the cutoff device on the desktop or wall of the area.
Secondly, after the installation is completed, turn it on, cut off the power supply, and turn on the power switch directly. After the equipment is connected, press the power switch to cut off the electrical equipment and it can work.
At this time, all mobile phones on the scene will be in the state of searching for the network and will lose the signal state of the base station.
The main performance of the mobile phone is to search the network, there is no signal, no service system and so on.
Even the caller and the called party cannot establish a normal call, and play their own role to realize the mobile phone signal jammer.
You can use it for the above usage.
The mobile phone signal is within a certain frequency range, after the mobile phone and the base station are linked by radio waves,
The transmission of data and sound is completed with a specific baud rate and modulation. If the mobile phone is blocked, it will not be possible to talk normally.
When using mobile phone shielding, it is better to buy some professional mobile phone signal shielding equipment. Professional hardware is not something that simple software can do.
Among them, strong magnetic fields or places with abnormal magnetic fields will interfere with the mobile phone signal to a certain extent.
The airplane mode that comes with the mobile phone is also a user-friendly mobile phone signal mode proposed to meet some occasions where the mobile phone signal is not allowed.
In the past few years, various types of mobile phone signal jammers have emerged in an endless stream, making us dazzled and dizzying.

There is a very special jammer that also appears in front of us, its name is wireless signal jammer, so what are the advantages of this type of product?
When we use a wireless signal jammer, you will find that no matter where we are, as long as such a jammer can be turned on,
Then everyone has no way to search for our wireless signal. In other words, the effect of household products is more obvious than that of ordinary public products.
In such an environment, we can always block all signals easily, but if we use a public blocker,
Then there may be a problem that the shielding effect is unstable, so we need to understand the specific use effect.
