When customers consult about mobile phone signal blockers, they often mention a common problem, that is, they have tried or purchased 5G signal blockers of other brands, but in actual use, they find that the shielding distance of these so-called 5G signal blockers is significantly shorter, and sometimes they cannot even block certain 5G frequency bands. This makes people wonder why this happens?<\/p>\n\n\n\n

The original intention of the design of 5G signal blockers is not only to maintain the shielding effect on the original standards or frequency bands of 2G, 3G, and 4G mobile phones, but also to effectively shield the 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. The frequency bands of 2G, 3G, and 4G mobile phones are all concentrated in these 8 frequency bands, and for the 5G communication frequency bands that will be used on a large scale in 2020, China Broadcasting and Television Mobile has added a total of 4 communication operators.<\/p>\n\n\n\n

At present, the distribution of 5G commercial frequency bands of the four operators is: 700MHz, 2600MHz, 3400MHz, and 3500MHz. In addition, there is 4800MHz, which has not been fully utilized and is mainly used for the construction of 5G private networks in specific locations.<\/p>\n\n\n\n

In summary, a fully functional 5G jammer<\/a> needs 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 are worried that some brands of 5G jammers may not perform well in actual use. This is probably because manufacturers have intentionally or unintentionally reduced or merged the above 12 frequency bands in order to control costs and reduce the price of 5G shielding products, resulting in poor shielding effect on 5G signals.

At present, most 5G jammer manufacturers adopt modular production and assembly for each frequency band in their products. Therefore, customers can judge whether the selected 5G jammer meets the basic functional design requirements by checking the number of built-in modules or the number of corresponding antennas.<\/p>\n\n\n\n
