Which 5G frequency bands should at least be included in a 5G signal jammer?
Since 2019, 5G jammers have been developed simultaneously with the rapid popularization of 5G mobile phones. Just as mobile phone users gradually abandon the original 4G mobile phones and buy new 5G mobile phones, those who have purchased 4G signal jammers before Customers have also begun to purchase and install 5G signal jammers in recent years. The key point that customers pay attention to when selecting products is not only to maintain the original 2G, 3G, 4G mobile phone signal interference function, but also to ensure the interference effect on 5G signals. Then the question arises: Which 5G frequency bands should at least be included in the 5G signal jammer?
According to the division of the 5G mobile phone communication frequency band by the radio authority, taking my country as an example, the frequencies used by 5G mobile phones include: the 758-788MHz frequency band belongs to China Radio and Television, the 2515-2675MHz frequency band belongs to China Mobile, and the 3400-3500MHz belongs to China Telecom, 3500-3600MHz belongs to China Unicom. The four 5G frequency bands listed here are all 5G signal jammer manufacturers will inevitably choose and install the corresponding 5G signal screen jamming module.
In addition to the above four 5G frequency bands, there is also a frequency band of 4800-4960MHz, which is allocated to China Mobile and China Radio and Television. It is used for the construction of private communication networks in some special places, and it is almost impossible to deploy base stations in the 4.8G frequency band in daily life. Because of this, most of the manufacturers of 5G signal jammers choose not to install signal shielding modules for the 4.8G frequency band from the perspective of saving and controlling production costs.
