The Declining Effectiveness of 5G Signal Blockers: Reasons and Solutions

In recent years, many customers who previously purchased and installed 5G signal blockers have reported a phenomenon. The 5G blockers that were installed earlier had excellent blocking effects initially, but gradually became ineffective in blocking 5G signals. This raises the question: What is the reason behind this decline in effectiveness?

The Gradual Popularization of 5G Signals in China:

The gradual popularization of 5G signals by the three major telecommunications operators in China began in the second half of 2019. This means that it was only from the second half of 2019 that these operators started deploying 5G base stations on a large scale. This process, from non-existence to establishment, naturally requires time. Consequently, the declining effectiveness of 5G signal blockers can be attributed to this process.

The Impact of Increasing Base Stations and Expanding Frequency Bands:

For instance, in 2020, when signal blockers were purchased, there were indeed 5G signal blocking modules available. However, due to the limited coverage of 5G base stations at that time, the signal strength was not very strong. As a result, the blockers were highly effective in blocking 5G signals. However, as we move into 2021 and 2022, with the increase in base stations and the addition of a fourth telecommunications operator in China, the frequency bands for 5G signals have also expanded. This gradual popularization of signals has led to a decline in the effectiveness of previously purchased 5G signal blockers.

The Need for Additional Modules to Supplement Signal Blocking:

Therefore, the reason behind the diminishing effectiveness of previously purchased 5G signal blockers is that they are unable to block the 5G signals from China Broadcasting Network Corporation Limited (CBN), the fourth telecommunications operator. This is primarily due to the increased frequency bands of 5G signals. To address this issue, it is necessary to add one or more modules to the blockers to supplement the blocking capability.

As the popularity of 5G signals continues to grow, it is crucial to understand the reasons behind the declining effectiveness of 5G signal blockers. The gradual establishment of 5G base stations and the expansion of frequency bands have contributed to this phenomenon. To ensure effective signal blocking, it is recommended to update the blockers with additional modules that can cover the increased frequency bands. By doing so, users can continue to enjoy the benefits of signal blocking in the era of 5G technology.
