In the construction of mobile signal jamming systems, the power supply for each device is an essential aspect of the construction process. As the construction unit responsible for the project, there is often a debate and uncertainty regarding whether to use AC or DC power supply for the entire mobile signal jamming system. This article aims to provide an explanation and clarification on this matter.
Differences and Advantages of AC and DC Power Supply:
AC power supply utilizes regular mains electricity to provide power to the devices in the mobile signal jamming system. AC electricity is commonly available on-site, with an ample number of AC power interfaces reserved for construction purposes. This facilitates convenient access to power for the construction team.

On the other hand, DC power supply involves converting AC power into DC power through a power conversion device. This DC power is then supplied to each signal jamming device in the system. The major advantage of this method is the ability to centrally manage the power supply for all devices, enabling unified power control such as turning them on or off simultaneously.
However, with the advancement of mobile signal jamming systems, particularly in the era of 5G, the power consumption of each individual device has increased significantly, with a minimum power requirement of 100W. If AC power supply is used, each node would only need to carry a current of less than 1A. In contrast, with DC power supply, each shielding terminal in the mobile signal jamming system typically requires a DC voltage of 5V or 12V. Based on calculations, it can be determined that each terminal would need to carry a current of approximately 15A-30A. This substantial current value poses stricter requirements on the wire diameter and transmission safety of the power supply line, leading to a significant increase in material costs.
Based on the analysis above, it is evident that the preferred power supply option for mobile signal jamming systems is currently AC power supply. This choice is primarily due to the lower current requirements and the convenience of accessing AC electricity on-site. However, as technology continues to evolve, it is essential to reassess the power supply options to ensure optimal performance and cost-effectiveness in future mobile signal jamming systems.
