With the rapid popularity of 5G smartphones since 2019, the development of 5G signal blockers has been synchronized. Just as mobile phone users gradually abandon their old 4G phones and switch to new 5G models, customers who previously purchased 4G signal blockers have also started to purchase and install 5G signal blockers in recent years. When selecting products, customers focus on maintaining the signal blocking function for their existing 2G, 3G, and 4G phones, while also ensuring effective blocking of 5G signals. This raises the question: which 5G frequency bands should be included in a 5G signal blocker?
5G Frequency Bands in China:
According to the division of 5G mobile communication frequency bands by the radio regulatory authority, taking China as an example, the frequencies used by 5G phones include: the 758-788MHz band, which belongs to China Broadcasting; the 2515-2675MHz band, which belongs to China Mobile; the 3400-3500MHz band, which belongs to China Telecom; and the 3500-3600MHz band, which belongs to China Unicom. In addition to these four 5G frequency bands, there is also a 4800-4960MHz band, which is allocated to China Mobile and China Broadcasting. However, this 5G frequency band is not widely used in China. According to feedback from China Mobile, the 4.8GHz band is mainly used for the construction of communication networks in special locations, and it is rarely deployed in daily life environments. From the perspective of saving and controlling production costs, most manufacturers choose not to install signal blocking modules for the 4.8GHz band.

Ensuring Effective Signal Blocking for 5G Frequencies:
To ensure effective signal blocking for 5G frequencies, a 5G signal blocker should include at least the following 5G frequency bands: 758-788MHz, 2515-2675MHz, 3400-3500MHz, and 3500-3600MHz. These frequency bands cover the major 5G networks in China, including China Broadcasting, China Mobile, China Telecom, and China Unicom. By blocking signals in these frequency bands, the 5G signal blocker can effectively prevent unwanted communication and maintain privacy and security.
As the popularity of 5G smartphones continues to grow, the demand for 5G signal blockers has also increased. Customers are now focusing on selecting signal blockers that not only block signals from 2G, 3G, and 4G phones but also effectively block 5G signals. In China, the 5G frequency bands used by 5G phones include the 758-788MHz, 2515-2675MHz, 3400-3500MHz, and 3500-3600MHz bands. While there is also a 4800-4960MHz band, it is not widely deployed in daily life environments. To ensure effective signal blocking for 5G frequencies, it is crucial for manufacturers to include the appropriate 5G frequency bands in their signal blockers. By doing so, customers can enjoy uninterrupted privacy and security in the era of 5G communication.
