Which frequency bands in the 5G mobile phone signal jammer overlap with the original 234G frequency band?
When a customer consulted us, the feedback said that the 4G mobile phone signal blocker purchased a few years ago could not block the current 5G mobile phone, but sometimes it was found that the 5G signal of some mobile phones would also be blocked. As a professional 5G mobile phone The manufacturer of the cell phone signal jammer 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 mobile phone signal jammer is turned on, will also play a shielding role. However, because it is only partially overlapped, when shielding 5G mobile phones, it shows that the shielding cannot be completely effective, or the shielding is unstable.
So, which frequency bands of the newly produced 5G mobile phone signal 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. In the past 4G mobile phones In the signal jammer, the shielding module of the 2.5G frequency band, if the redundancy of the bandwidth is included, can often cover the 100MHz bandwidth of 2535-2635MHz, so the old mobile phone signal jammer is produced. It can block the phenomenon of some 5G 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 is only for individual phenomenon, and even if it is really used, the new 5G mobile phone signal blocker will still effectively block all 2345G signals completely.
