5g signal blocker is also called wifi signal blocker and jammer, etc. It can block the mobile phone signal, so that the mobile network cannot communicate and surf the Internet normally, so as to achieve the purpose of interference, it only blocks the mobile phone signal, The wireless network signal has no effect on other electronic devices, so what should be paid attention to when using a 5G signal jammer?
1. If you want to understand how the 5G wifi signal jammer works, you need to understand the principle of mobile communication first. The mobile phone works within a certain frequency range, so that the base station and the mobile phone can communicate with each other through radio waves. baud rate and modulation method to complete the transmission of sound and data.
2. During the working process of the 5G signal jammer, it must scan quickly from the low-end frequency of the forward channel to the high-end at a certain speed. This scanning speed can form garbled information in the received message signal of the mobile phone, so that The mobile phone cannot detect the normal data sent from the base station, so it cannot effectively connect with the base station. At this time, the performance of the mobile phone is that there is no signal, no service system, and the search network cannot be found.
3. When you use 5G signal jammers, if you want to achieve the interference of the jammer to the mobile network, you need to ensure that the signal field strength sent by the jammer is much higher than the field strength of the mobile signal in the area where the interference is implemented. Generally, The closer the interference site is to the base station, the stronger the field strength, and thus the smaller the effective interference area. When the mobile phone is communicating, the connection with the base station is carried out through the uplink frequency, and then the signal is transferred to the mobile service switching center, so that the call can be realized.
