In recent years, the demand for 5G signal blockers has increased as more customers seek to shield their mobile devices from unwanted signals. However, some customers have reported unsatisfactory results when using certain brands and models of 5G signal blockers. This article aims to explore the reasons behind these shortcomings and shed light on the importance of comprehensive frequency coverage for effective signal blocking.
The Importance of Comprehensive Frequency Coverage:
A 5G signal blocker is designed to not only block the existing 2G, 3G, and 4G frequencies but also effectively shield the specific frequencies and bands associated with 5G technology. In China, the mobile frequencies used by the three major telecom operators, China Mobile, China Unicom, and China Telecom, are concentrated within eight frequency bands: 800MHz, 900MHz, 1800MHz, 1900MHz, 2000MHz, 2100MHz, 2300MHz, and 2500MHz. However, with the introduction of China Broadcasting Network Corporation Limited (CBN) in 2020, there are now four telecom operators in total.
The Distribution of 5G Commercial Frequencies:
Currently, the four telecom operators in China utilize the following 5G commercial frequencies: 700MHz, 2600MHz, 3400MHz, 3500MHz, and 4800MHz. It is important to note that the 4800MHz frequency is not widely used and is primarily employed for specific 5G private network constructions. Therefore, a fully qualified 5G signal blocker should cover a total of 12 frequency bands: 700MHz, 800MHz, 900MHz, 1800MHz, 1900MHz, 2000MHz, 2100MHz, 2300MHz, 2500MHz, 2600MHz, 3400MHz, and 3500MHz.
Possible Reasons for Ineffective Signal Blocking:
When customers encounter poor performance with certain brands or models of 5G signal blockers, the most likely explanation is the lack of complete coverage for the aforementioned 12 frequency bands. It is possible that, in an attempt to control costs and reduce the selling price of 5G signal blockers, some manufacturers intentionally or unintentionally reduce or merge these frequency bands. As a result, the effectiveness of signal blocking for 5G frequencies is compromised.

Consideration of Internal Modules and Antenna Quantity:
To determine the coverage capabilities of a particular 5G signal blocker, it is essential to assess the number of internal modules or antennas it possesses. The number of internal modules or antennas should correspond to the 12 frequency bands mentioned earlier. By ensuring that a 5G signal blocker has the necessary internal components, customers can have confidence in its ability to provide comprehensive signal blocking across all relevant frequencies.
Conclusion:
In conclusion, the effectiveness of 5G signal blockers is heavily dependent on their ability to cover the full range of frequencies associated with 5G technology. Customers who have experienced subpar results with certain brands or models of 5G signal blockers may find that these devices lack complete coverage of the 12 frequency bands required for optimal performance. By understanding the importance of comprehensive frequency coverage and considering the internal components of a 5G signal blocker, customers can make informed decisions and select products that meet their specific needs.
