Currently, there are different types of test room type smart jammer on the market, and the power consumption of the power supply is mostly between 100-200W. According to this value, it can be calculated that if multiple devices are connected in parallel on a power line in a building or a floor, the total power consumption of the line can be obtained by multiplying the number of test room type smart jammer by the power consumption of a single device, and then selecting the wire diameter of the power supply cable based on this.

After the client has purchased several test room type smart jammer , before entering the site to prepare for installation and construction, how to solve these problems related to the power consumption of the test room type smart jammer hield and how to select the cable diameter. The power consumption of this test room type mobile phone signal shield has been clearly indicated in the product information or instructions obtained prior to purchase. Note: The power consumption of a test room type smart jammer to the power consumption of the power supply used to power the device. This is not the same concept as the nominal RF transmission power of the test room type mobile phone signal shield (the ratio of the total RF transmission power of a device to the power consumption of the device's power supply, which is approximately 1:3 or 1:4).
