Mobile phone signal jammers gradually appear in our lives, bringing us a different experience. Do you know about mobile phone signal jammers? How much do you know about mobile phone signal jammers? Next, the editor will introduce to you, I hope it can be helpful to everyone.
The cell phone jammer is a magical thing. After use, it will produce very strange changes when installed indoors. But no one can see this change. Therefore, many people wonder how a small thing can have such a large amount of energy, and even some people will take the risk. What happens to the mobile phone after signal shielding is used?
There is a mobile phone signal jammer in the room, and you will find that you can't make or receive calls at all, and you can't connect to the Internet, so you can't receive information, etc. In addition, the Bluetooth function of the mobile phone is not available for the test room signal jammer with Bluetooth function. This can avoid using devices like Bluetooth headsets to make or receive calls. The mobile phone signal jammer does not interfere with the work of other electronic devices. After using the jammer, it is safer and more concealed.
When a mobile phone works, it connects the mobile phone to the base station through radio waves within a certain frequency range, and completes the transmission of data and sound with a certain baud rate and modulation. According to this communication principle, in the working process, the wireless signal jammer scans from the low frequency of the front channel to the high end at a certain speed. This scanning speed will cause garbled interference in the information signal received by the mobile phone, and the mobile phone cannot detect normal data from the base station, resulting in the inability to establish a connection with the base station. Mobile phones have the characteristics of network search, no signal, no service system and so on.
usage:
Select the area where the mobile phone signal needs to be cut off, and place the cut-off device on the desktop or the wall in this area.
After installation, turn on the power of the circuit breaker and turn on the power switch.
After the equipment is turned on, press the power switch and the disconnector can work. At this moment, all opened mobile phones are in the network search state, and the base station signal is lost. None of the callers can establish a call connection.
