When discussing the main technical indicators of wireless signal blockers, key terms such as transmission power and power consumption are often mentioned. Why are transmission power and power consumption in wireless signal blockers easily a cause for concern? What key impacts do they have on product performance? This article aims to explore these questions and shed light on the significance of transmission power and power consumption in wireless signal blockers.

Transmission Power in Wireless Signal Blockers

Transmission power in wireless signal blockers can be divided into two parts. Firstly, there is the overall transmission power of the device, which is the cumulative sum of the transmission power of each RF module in the wireless signal blocker. Secondly, there is the transmission power in different frequency bands.

Currently, mainstream wireless signal blockers can be roughly categorized into three levels based on the transmission power of their modules. The first level consists of low-power wireless signal blockers, with each module having a transmission power of 2-3W and the overall transmission power of the device typically ranging from 30-40W. The second level comprises medium-power wireless signal blockers, with each module having a transmission power of 10-20W and the overall transmission power of the device usually ranging from 200-300W. The third level consists of high-power wireless signal blockers, with each module having a transmission power of 50-100W and the overall transmission power of the device typically ranging from 500W-1500W. It is important to note that this is a general classification, as the overall transmission power of the device is directly proportional to the number of RF modules it contains.

Power Consumption in Wireless Signal Blockers

In the field of RF technology, there is a proportional relationship between the power of RF transmission and the power consumption of the power supply, typically ranging from 1:2 to 1:3. For example, if a wireless signal blocker has a total RF power of 100W, its power consumption would be approximately 250W.

One might wonder why power consumption is significantly higher than RF power. Where does this additional energy consumption go? The answer is relatively simple. In a wireless signal blocker, approximately 1/3 of the power consumption is converted into RF power, while the remaining portion is natural losses from power supply conversion and thermal energy. This is why every wireless signal blocker is equipped with a large-sized heat sink.

Transmission power and power consumption are crucial factors to consider when evaluating the performance of wireless signal blockers. The transmission power determines the effectiveness of signal blocking in different frequency bands, while power consumption affects the overall energy efficiency and heat dissipation of the device. By understanding these technical indicators, users can make informed decisions when selecting wireless signal blockers for their specific needs.
