Does mobile phone jammer need to cover the 4800M frequency band?

  • 2022-06-07


Now the mainstream mobile phone jammer can interfere with the 2G, 3G, 4G and 5G signals of the mobile phone at the same time, and the interference modules inside the mobile phone jammer usually have at least 10 or more, which are disclosed by various mobile phone jammer manufacturers. In the product technical information, it can be seen that most manufacturers have marked the interference module for the 4800-4900MHz frequency band. Then, in the existing communication network environment, does the mobile phone jammer need to interfere with the 4800-4900MHz frequency band?

According to public information, the 4800MHz frequency band is just an abbreviation, it actually refers to 4800-5000MHz, which is mainly used in the N79 frequency band of 5G mobile phones. In mainland China, 4800-4900MHz is allocated to China Mobile 5G, 4900-4960MHz It was assigned to China Radio and Television. When mobile phone jammer interfere with all 5G signals, of course, the 4800MHz frequency band cannot be ignored. However, as far as we know, China Mobile and China Radio and Television, the two communication operators, have not been fully deployed nationwide. 5G base station in the 4800MHz band. In particular, China Mobile only uses the 4800MHz frequency band as a small-scale local private network in very few regions and occasions.

Therefore, in most provinces, cities and regions in China, our 5G mobile phones cannot receive the base station signal from the 4800MHz frequency band, which will lead to an embarrassing result: in fact, the 4800MHz installed in the mobile phone jammer The interference module is a bit redundant. With or without this interference module, it has no effect on the overall interference effect of the mobile phone. So, can the 4800MHz module in the mobile phone jammer be omitted and no longer installed? In the short term, it is possible, and there will be no problem in two or three years. Even if operators fully open and popularize the 4800MHz frequency band in the future, it will be feasible to add installation at that time.
