When a customer consulted us, the feedback said that the 4G jammer purchased a few years ago could not interfere with the current 5G mobile phone, but sometimes it was found that the 5G signal of some mobile phones would also interfere. As a professional 5G jammer The manufacturer clearly gave the customer an answer. This is because some of the 5G frequency bands used by the current 5G mobile phones do overlap with the original 234G frequency band. And this part of the overlapping frequency band, when the jammer is turned on, will also play a role in jamming. However, because it is only partially overlapped, when it interferes with 5G mobile phones, it shows full interference that is not completely effective, or the interference is unstable.

So, which frequency bands of the newly produced 5G jammers overlap with the original 234G frequency band? Specifically, according to the information disclosed by the Ministry of Industry and Information Technology, the 5G frequency bands allocated to operators are: 758-788MHz, 2515-2675MHz, 3400-3600MHz and 4800-4960MHz. China Mobile's 2515-2675MHz overlaps with the 2555-2655MHz originally used for 4G frequency bands a few years ago. In practical applications, China Mobile really uses 2535-2635MHz, a total of 100MHz of bandwidth frequency. In the past 4G interference In the 2.5G frequency band interference module, if the redundancy of the bandwidth is included, it can often cover the 100MHz bandwidth of 2535-2635MHz, so the old jammer can interfere with part of the 5G. The phenomenon of mobile phones.

However, in some hotspot areas or extremely densely populated places in the city, we have also found that some operators have exceeded the frequency bandwidth usage specifications issued by the Ministry of Industry and Information Technology, and used 5G signals in other 234G frequency bands, but this only belongs to individual phenomenon, and even if it is really used, the new 5G jammer will still effectively completely jam all 2345G signals.
