The Importance of Frequency Division and Module Quantity in 5G Mobile Phone Signal Blockers

With the rapid development of 5G technology, 5G mobile phone signal blockers have gained widespread recognition and usage among users. However, unlike the previous 2G, 3G, and 4G eras, the design of 5G signal blockers has undergone significant changes. Most manufacturers have shifted towards integrating antennas and main units, abandoning the external antenna appearance. This not only enhances the overall aesthetics of the device but also accommodates the need for additional shielding modules to cover multiple 5G frequency bands.

The Challenge of Concealed Components:

While the integration of key components within the 5G mobile phone signal blocker’s casing offers a visually appealing design, it presents a challenge for customers to determine the number of shielding modules used and evaluate the specific frequency band division of the device. This lack of transparency hinders the ability to assess the effectiveness of the signal blocker.

The Impact of Frequency Division and Module Quantity:

The final shielding effect of a 5G mobile phone signal blocker is closely related to the frequency band division and the quantity of shielding modules used. In the pre-5G era, a conventional and reasonable frequency band division typically consisted of eight modules. However, with the introduction of 5G, additional frequency bands such as the 700M, 3400M, and 3500M bands have become essential. Furthermore, the TDD-LTE frequency band previously allocated to China Mobile’s 4G network has expanded from 2555-2655MHz to 2515-2675MHz, with a bandwidth increase from 100M to 160M. To ensure effective shielding for this frequency band, it is recommended to split it into two modules, each covering a bandwidth of no more than 100M.

The Optimal Frequency Division and Module Quantity:

Considering the aforementioned analysis, a reasonable frequency band division for a 5G mobile phone signal blocker should consist of 11-12 modules. This ensures comprehensive coverage of the various 5G frequency bands and allows for effective shielding.

Conclusion:

As 5G technology continues to advance, the integration of antennas and main units in 5G mobile phone signal blockers has become the norm. While this design choice enhances the overall aesthetics of the device, it poses challenges for customers in determining the number of shielding modules used and evaluating the frequency band division. To achieve optimal shielding effectiveness, it is crucial to consider the appropriate frequency division and module quantity. By doing so, users can make informed decisions when selecting a 5G mobile phone signal blocker that meets their specific needs.
