Improving the Shielding Effectiveness of 5G Mobile Phone Interference Devices

With the advent of the 5G era, 5G mobile phone interference devices have been developed and are readily available in the market. However, some customers have reported that the shielding effect of these devices for 5G signals is not as effective as it was for 3G and 4G signals. This article aims to explore the reasons behind this issue and provide methods to enhance the shielding effectiveness of 5G mobile phone interference devices.

The Development of 5G:

To understand the current situation, it is important to know the development of 5G technology. According to publicly available technical information and data released by various network operators, 5G communication base stations have significantly higher signal strength compared to 3G and 4G base stations. 5G operates in higher frequency bands, specifically above 2.5GHz, which have wider frequency bandwidth but weaker diffraction capabilities and shorter transmission distances. Consequently, the density of 5G base stations is much higher than before. While this ensures stable and reliable 5G experiences for mobile phone users, it also poses challenges for 5G mobile phone interference devices.

Reasons for Poor Shielding Effectiveness:

The increased transmission power and higher density of 5G base stations have made it more difficult for 5G mobile phone interference devices to effectively shield 5G signals. This is why some customers have noticed a decrease in shielding effectiveness compared to previous generations. The question arises: why do some locations exhibit poor shielding effectiveness? And what methods can be employed to enhance the shielding effectiveness of 5G mobile phone interference devices?

Methods to Enhance Shielding Effectiveness:

Firstly, it is crucial to understand that signal shielding is essentially power suppression, and the effectiveness depends on the strength of the emitted signal. Therefore, customers can request the manufacturers of 5G mobile phone interference devices to ensure or increase the transmission power in the 5G frequency band. This step is essential to improve the shielding effectiveness.

Secondly, when selecting 5G mobile phone interference devices, it is important to carefully consider the number of 5G shielding modules installed in the device. Generally, the more modules dedicated to 5G shielding and the finer the frequency division, the better the final shielding effectiveness. Additionally, devices equipped with high-power shielding modules for the frequency band should be preferred.


As the 5G era progresses, it is crucial to address the challenges faced by 5G mobile phone interference devices in effectively shielding 5G signals. By understanding the development of 5G technology and implementing the methods mentioned above, customers can enhance the shielding effectiveness of these devices. This will ensure a better user experience and mitigate the potential interference caused by the increased transmission power and density of 5G base stations.
