Mobile phone signal blockers, also known as frequency band blockers, are devices used to block or disrupt mobile phone signals in specific areas. These blockers are categorized into three power levels: low-power, medium-power, and high-power. The choice of power level depends on the application environment. However, there is a common question among customers regarding the effectiveness of low-power blockers when installed outdoors. This article aims to address this question and provide insights into the appropriate use of low-power blockers in outdoor environments.
Power Levels of Mobile Phone Signal Blockers:
Mobile phone signal blockers are divided into three power levels based on their transmission power. The first level is the low-power type, which refers to blockers with transmission power below 2-3W. The second level is the medium-power type, with transmission power ranging from 10-20W. The third level is the high-power type, with transmission power reaching 50W or even 100W. Different application environments require different power levels of mobile phone signal blockers.

Effectiveness of Low-Power Blockers in Outdoor Installations:
In general, for open and spacious outdoor areas, it is recommended to use high-power mobile phone signal blockers. On the other hand, low-power blockers are suitable for indoor environments. Installing low-power blockers outdoors is rare and only done in exceptional circumstances. When low-power blockers are installed outdoors, their effective blocking range is typically limited to 2-5 meters. This limited range is due to their lower transmission power. Customers are unlikely to be satisfied with such a minimal blocking distance.
Factors Affecting the Effective Range of Mobile Phone Signal Blockers:
The actual blocking range of mobile phone signal blockers is closely related to the signal strength of the mobile phones in the area. The stronger the mobile phone signal, the shorter the effective blocking distance. In outdoor environments, the signal strength is generally at least 10dB higher than in indoor environments. Therefore, high-power blockers are preferred for open and spacious outdoor areas, while low-power blockers are suitable for indoor use.
Challenges of Using Low-Power Blockers Outdoors:
As mentioned earlier, low-power mobile phone signal blockers have a limited effective range when installed outdoors. Achieving extensive coverage would require dense installation using a cellular network approach. This approach is not practical for several reasons. Firstly, it would require the purchase of a large number of low-power blockers. Secondly, providing power supply and installation for numerous devices would be cumbersome and inconvenient.
Conclusion:
In conclusion, low-power mobile phone signal blockers are not as effective when installed outdoors compared to high-power blockers. Their limited transmission power results in a shorter effective blocking range. It is crucial to consider the application environment and choose the appropriate power level of the blocker accordingly. While low-power blockers are suitable for indoor use, high-power blockers are recommended for open and spacious outdoor areas.
