Smartphones are a tool for communication. However, mobile phones are not allowed in some special places, such as test centers and libraries. WiFi jammers have appeared and there are many such products on the market, but there are some technical requirements to meet the quality of this product. At present, communication technology is also developing, and there are higher requirements for the function of the signal blocking device.
Is mobile jammer harmful to human body? By design, this interference device uses a highly efficient heat-dissipating aluminum alloy device to ensure long-term stable operation of the machine without worrying that overheating will damage the machine. The strength of the electromagnetic signal from the wifi jammer is very weak, which is not enough to harm the human body. Please use it with confidence.
