When customers inquire about wireless signal blockers, they often only mention their desired coverage range and a price they are willing to pay. However, they are often surprised by the price difference when it comes to technical specifications and specific product recommendations. This is because customers may not fully understand the relationship between the transmission power and coverage range of wireless signal blockers.
The Different Power Levels:
To explain this further, let’s take the example of wireless signal blockers commonly used for mobile phone applications. These blockers can be divided into four power levels based on their transmission power:
1. Low Power Level:
This refers to blockers with a transmission power of 0.5-1W per frequency band. These handheld or portable blockers are characterized by their small size and light weight. However, their coverage range is limited, typically suitable for indoor use only, with an effective radius of 1-5 meters.
2. Medium Power Level:
Blockers in this category have a transmission power of 2-5W per frequency band. They are the most common type of wireless signal blockers and offer a high cost-performance ratio. Most manufacturers design them as desktop or wall-mounted devices, primarily for indoor use. Their coverage range extends from 5 to 20 meters.
3. High Power Level:
This refers to blockers with a transmission power of approximately 10-20W per frequency band. When wireless signal blockers reach this power level, they are suitable for outdoor applications. However, they can also be used indoors, especially in large open spaces such as theaters, conference halls, and factory workshops. Their effective coverage radius can reach 20-50 meters.
4. Very High Power Level:
This category includes blockers with a transmission power of 50W or 100W per frequency band. These high-power wireless signal blockers are specifically designed for outdoor use, such as in large prison towers or to protect large oil storage areas. They are also suitable for mobile work environments, such as in modified vehicles.
Conclusion:
It is crucial for customers to understand the relationship between transmission power and coverage range when considering wireless signal blockers. Often, customers may request a large coverage range but expect a lower-priced device, not realizing the significant price difference between high-power and low-power products in the signal blocking field. By understanding the different power levels and their corresponding coverage ranges, customers can make informed decisions and choose the most suitable wireless signal blocker for their specific needs.
