What are the advantages of built-in cell phone jammers compared to external cell phone jammers?

In terms of energy saving and heat dissipation, the built-in cell phone blocker is slightly worse than the external cell phone signal jammer. In terms of external structure, the built-in mobile phone signal jammer is an external plastic shell that combines a transmitting antenna, a power supply and a heat sink. Some school examination rooms, conference rooms, and confidential places have great advantages in occasions with large traffic.

The external mobile phone signal jammer, structurally speaking, adopts thickened pure aluminum alloy, and combines the circuit board with the shell through various processes such as oxidation and baking paint, and fully utilizes its own shell to achieve a good heat dissipation effect. , Because the antenna uses SMA head external connection, the power supply is external and inconvenient for long-term mobile use, the operation is more complicated, and the installation is not convenient, but its own advantages are also very strong, the external heat dissipation effect is very obvious, this is Because the outside of the transmitting antenna and the shield are matched with each other, the heat dissipation effect is better. Because the power supply of the external mobile phone signal jammer is separated from the host, it can reduce the burden of the host, so that the external mobile phone signal jammer can work better and stably for a long time. Based on the above characteristics, the external mobile phone signal jammer is more suitable for fixed occasions that require long-term continuous work and stable use, such as school classrooms, student dormitories, churches, troops, prisons, and detention centers.
