Can a mobile phone signal jammer shield 4G signals?

Today, I will talk to you about whether the mobile phone signal jammer can effectively shield the 4G network signal? This topic will help everyone have a more comprehensive understanding of the signal jammer. Next, the editor summarized a few pieces of knowledge about mobile phone signal jammers.

1. In addition to the 4G network signals that have been widely used, the commonly used mobile communication network signals include the 3G network signals that were popular in the past few years, as well as the 2G network signals used by some elderly phones. Although 5G network signals have become a topic of discussion by many people, it will take some time before they can reach 5G networks.

2. The first thing to be clear is that the mobile phone signal jammer can shield 4G network signals. When the mobile phone is operating in a certain frequency range, the mobile phone and the base station are connected by radio waves, and the transmission of data and sound is completed with a certain baud rate and modulation method. Aiming at this communication principle, the mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data announced from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested in the phenomenon of searching the network, no signal, no service system, etc.

3. The key to shielding 4G network signals depends on the frequency supported by the selected mobile phone signal jammer. The current 4G frequency range is very wide, from 800M-2. 4G, if you want to shield 4G signals, it depends on what you use for shielding. How much bandwidth can the device support? Because some of the 4G frequency band almost overlaps with WIFI 2.4. Once you shield the 4G signal, the WIFI and Bluetooth in the shielded area may not work properly. Therefore, whether the 4G signal can be shielded depends on the function of the shielding product, whether the device has a 4G signal shielding module.
