Today we are going to talk about the shielding effect of mobile phone signal blockers on 4G network signals. The theme of this issue is to give you a comprehensive understanding of signal blockers. Here are a few key points to note:<\/p>\n\n\n\n

1.Mobile communication network signals:<\/h2>\n\n\n\n

In addition to the widely popular 4G network signals, there are also 3G network signals that were popular in previous years and 2G network signals used by old mobile phones. Although the discussion of 5G network signals is still ongoing, it will take some time for 5G to be popularized. Popular GPS jammers<\/a> and WIFI jammers<\/a> in Europe and America.<\/p>\n\n\n\n

2.Shielding 4G network signals:<\/h2>\n\n\n\n

It is obvious that mobile phone signal blockers can block 4G network signals. When the mobile phone is working, it works within a specific frequency range. The mobile phone communicates with the base station through radio waves, transmitting data and sound at a specific baud rate and modulation method. Based on this communication principle, when the mobile phone signal blocker is working, it will scan the frequency range of the forward channel from low to high at a certain speed. This scanning speed will cause garbled interference in the information signal received by the mobile phone, and the normal data sent by the base station cannot be detected, resulting in the inability of the mobile phone to establish a connection with the base station, and there will be no network, no signal, no service and other phenomena.<\/p>\n\n\n\n

3.Key factors in shielding 4G network signals:<\/h2>\n\n\n\n

The ability to shield 4G network signals depends on the frequency range supported by the selected cell phone signal jammer<\/a>. Currently, the 4G frequency band ranges from 800MHz to 2.4GHz. To effectively shield 4G signals, the bandwidth supported by the jammer<\/a> must be considered. It should be noted that part of the 4G frequency band overlaps with the 2.4GHz frequency used by Wi-Fi. Shielding 4G signals may inadvertently disrupt Wi-Fi and Bluetooth functions in the shielded area. Therefore, the ability of a signal jammer to block 4G signals depends mainly on the functions and components of the jammer, including whether it has a dedicated 4G signal shielding module.<\/p>\n\n\n\n
