As the name suggests, the cell phone signal jammer is a professional device that can interfere with mobile phone signals. It is used in many places, such as school examination rooms, libraries, courts and hospitals, etc. So how to use the jammer better? Here is a brief introduction.

The use of the mobile phone signal jammer is relatively simple. First, select an area where the mobile phone signal needs to be interfered, and then place the jammer in a suitable position in this area, which can be on the wall or on the desktop; then you can connect the power supply to conduct a pre-installation test, and after the test is completed, you can install it. It can be fixed on the wall or placed in the ceiling. After installation, it can be powered on and used; at this time, all mobile phones on the scene are in the network state of searching, and it has lost the signal of the base station. Whether it is the caller or the called party, it cannot establish a call connection.

The interference range of the mobile phone signal jammer is mainly related to the electromagnetic signal field strength at the site of use, and also to the distance from the site of use to the communication base station. If there is no base station within 300 meters around the site, the interference range will be larger and the interference effect will be better.

Some friends are worried that the radiation from mobile phone signal jammers is harmful to the human body. In fact, any electronic product will generate some electromagnetic radiation to a greater or lesser extent. The country has strict national standards for electromagnetic radiation. As long as the radiation value of the equipment is below the national standard, it can be determined that the electromagnetic radiation generated by the equipment is safe and harmless to the human body. The radiation value generated by mobile phone signal jammers is lower than the national standard, and the human body is not exposed to electromagnetic radiation at close range for a long time, so it is not harmful to the human body. It can be said that there is almost no harm.

The above is about the use of cell phone signal jammers and the issues that the public is more concerned about. When using the jammer, you can follow the above method to operate. You only need to install and connect it, plug in the power supply and you can use it. When using it, you also need to choose a suitable location so that you can achieve a better interference effect.
