Mobile signal blockers are devices designed to block all types of mobile signals from the four major mobile network operators, including 2G, 3G, 4G, and 5G signals. These devices cover a wide range of frequency bands, including 700MHz, 800MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz, 2600MHz, 3400MHz, 3500MHz, 4800MHz, and more. They can also block the built-in Wi-Fi signals of mobile phones, such as Wi-Fi 2.4G (including Bluetooth) and Wi-Fi 5.8G. However, some customers have expressed concerns about the limited range of signal blocking when using mobile signal blockers in certain locations. They expect the power of these devices to be increased in order to significantly improve the range of signal blocking. This article explores whether increasing the transmit power of mobile signal blockers leads to a greater signal blocking distance and better blocking effectiveness.
The Relationship Between Transmit Power and Signal Blocking Distance:
According to the existing working theory of conventional mobile signal blockers, increasing the transmit power does indeed result in a greater signal blocking distance and better blocking effectiveness. However, it is important to note that the signal emitted by mobile signal blockers belongs to the category of radio frequency (RF) wireless signals. Increasing the transmit power of RF wireless signals is not as simple as upgrading a few power amplifier components. It requires the selection of higher power output amplifiers and the design of dedicated amplifier circuits. Moreover, increasing the power also requires a hierarchical push. As the power load increases, the cost of RF components increases exponentially.

Challenges and Considerations:
Increasing the transmit power of mobile signal blockers also presents several challenges. Firstly, the device itself needs to be redesigned to accommodate the increased heat generated by higher power. This requires larger heat sinks and additional measures for ventilation and heat dissipation, which in turn increase the size, weight, and cost of the equipment.
Alternative Solution: Higher Gain Antennas:
To enhance the blocking effectiveness of mobile signal blockers, a simpler, faster, and cost-effective solution is to choose antennas with higher gain. Since the signal emitted by mobile signal blockers is ultimately transmitted through antennas, replacing the original antenna with one that has a higher gain can significantly increase the transmit power. For example, if the original antenna has a gain of 2dB and it is replaced with an antenna with a gain of 5dB, according to the calculation method for RF power, every 3dB increase in gain is equivalent to doubling the transmit power.
Conclusion:
While increasing the transmit power of mobile signal blockers can potentially improve the signal blocking distance and effectiveness, it is not a straightforward process. It requires careful consideration of the design, cost, and heat dissipation requirements. Alternatively, choosing antennas with higher gain can provide a simpler and more cost-effective solution to enhance the blocking effectiveness of mobile signal blockers. Ultimately, the choice depends on the specific requirements and constraints of the intended application.
