When customers consult about mobile phone shielding devices, they often mention a common problem, that is, they have tried or purchased 5G jammer devices of other brands, but found that the shielding distance of these devices is significantly shorter, and sometimes they cannot even shield certain 5G frequency bands. This makes people wonder, why does this happen?<\/p>\n\n\n\n

The purpose of the design of 5G jammer<\/a> devices is to maintain the shielding effect of the original 2G, 3G, and 4G standards or frequency bands, and to effectively shield specific 5G standards and frequency bands. The original frequency bands of 2G, 3G, and 4G mobile phones include 800MHz, 900MHz, 1800MHz, 1900MHz, 2000MHz, 2100MHz, 2300MHz, and 2500MHz, while the frequency bands of 3G and 4G mobile phones are concentrated in these eight frequency bands. From the perspective of the 5G communication frequency bands that will be widely used in 2020, there are four communication operators including China Broadcasting and Television Mobile.<\/p>\n\n\n\n

At present, the 5G commercial frequency bands of these four operators are distributed as follows: 700MHz, 2600MHz, 3400MHz, and 3500MHz. It is worth noting that 4800MHz is not widely used and is mainly used to build 5G private networks in specific areas.<\/p>\n\n\n\n

To give full play to the role of 5G jammers<\/a>, qualified 5G jammers need to cover the following frequency bands: 700MHz, 800MHz, 900MHz, 1800MHz, 1900MHz, 2000MHz, 2100MHz, 2300MHz, 2500MHz, 2600MHz, 3400MHz, and 3500MHz, a total of 12 frequency bands.<\/p>\n\n\n\n

Customers’ concerns are justified, because some brands of 5G jammers are not ideal in actual use. This is often due to the intentional or unintentional reduction or merger of the 12 frequency bands. Manufacturers may reduce the price of 5G shielding products in order to control costs, resulting in poor 5G signal shielding effects.

At present, most 5G jammer manufacturers’ products are produced and assembled in modular format for each frequency band. Therefore, when evaluating whether the 5G jammer to be purchased meets the basic functional design requirements, it is necessary to check the number of built-in modules or the corresponding number of antennas in each frequency band.<\/p>\n\n\n\n
