Can mobile network jammers only block 5G signals?
Recently, a customer proposed a special functional requirement to us: mobile network jammers only block 5G mobile phone signals, while retaining 2G, 3G, and 4G signals. They asked us, as a professional manufacturer of mobile network jammers, if we can achieve this function of only blocking 5G signals.
Firstly, based on the frequency band division standards of several domestic operators, a mobile network jammer that only blocks 5G signals and does not affect the normal communication of other standard mobile phone signals can be customized. This requirement can be met and implemented. Taking the 5G mobile phone frequency band used by the four major mobile communication operators in Chinese Mainland as an example, since the 5G signal frequency band used by each operator is relatively clear and fixed, we only need to install the 5G signal mask module for the fixed frequency band in the 5G mobile network jammer. For example, China Mobile's 5G in the 2.6G frequency band has a specific frequency range of 2515-2675MHz, China Mobile's 5G in the 0.7G frequency band shared with China Broadcasting and Television has a specific frequency range of 758-788 MHz, China Telecom's 5G in the 3.5G frequency band has a specific frequency range of 3400-3500 MHz, and China Unicom's 5G in the 3.6G frequency band has a specific frequency range of 3500-3600 MHz.
If only 5G signals need to be shielded, it is only necessary to fully cover the four 5G frequency bands mentioned above, which means that the mobile network jammer should include at least four 5G signal shielding modules. Of course, this is only to meet the basic requirement of shielding 5G signals. If we want to further improve the shielding effect of 5G, we suggest splitting the four 5G frequency bands mentioned above and dividing the frequency range originally covered by each module in the 5G mobile network jammer into two. This can allow the same module power to act on a narrow frequency bandwidth, which helps to improve the shielding effect of 5G signals.
