The Use and Functionality of Signal Jammers

In today’s world, it has become common for individuals to carry a mobile phone with them at all times. People use their phones to make calls and send messages throughout the day. However, in certain confidential offices and meeting rooms, the use of signal jammers has become necessary to prevent information leakage and interference. Signal jammers are primarily used in various settings such as examination halls, schools, gas stations, conference centers, hospitals, prisons, and other places where the use of mobile phones is prohibited. These devices have adjustable shielding radius and can cover a large area. However, it is important to be cautious while using Signal Jammers to avoid interference with other electronic devices.

Choosing the Right Device:

When installing a Signal Jammer, it is crucial to keep a safe distance from commonly used devices such as speakers, wireless microphones, radios, computers, televisions, and Wi-Fi routers. This precautionary measure ensures that the signal jammer does not interfere with the functioning of these devices. Depending on your requirements, you can choose between high-power or low-power signal jammers. These devices are capable of effectively blocking all 2G, 3G, 4G, 5G, and Wi-Fi signals from mobile network providers like China Mobile, China Unicom, and China Telecom.

How to Use a Signal Jammer:

  1. Select the area where you want to block mobile phone signals and place the Signal Jammer on a desk or wall in that area.
  2. After installing and connecting the device, switch on the power button. Pressing the power button will activate the signal jammer.
  3. Once activated, all mobile phones within the vicinity will enter a network search mode, causing the connection with the base station signal to be interrupted.


In conclusion, Signal Jammers have become essential tools in various settings where the use of mobile phones is prohibited. By following the aforementioned steps, you can effectively utilize a signal jammer to block mobile phone signals. However, it is important to be aware of the potential interference with other electronic devices and maintain a safe distance from them. Understanding the purpose and functionality of Signal Jammers is crucial for their proper usage.
