Mobile Cell Phone Detector Affects External Signals

In order to ensure the information security of the examination room, the school generally uses mobile phone signal jammers to interfere with external signals within a certain range. Today, Xiaobian, a well-known domestic mobile phone signal jammer manufacturer, will talk to you about how the school Mobile Cell Phone Detector interferes with mobile phone signals. To understand how cell phone signal jammers interfere with cell phone signals, you must first know the working principle of mobile communication. Simply put, it is within a certain frequency range. The modulation method completes the transmission of data and sound. Let's know what a cell phone signal jammer is. Cell phone signal jammers are also called cell phone signal blockers, cell phone signal jammers, and secrecy devices. Their working principle is to implement co-frequency electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile network cannot communicate normally, so as to achieve the purpose of interference.

The high-power Mobile Cell Phone Detector antenna emits high-power radio frequency signals. The antenna is installed outside the car body. The metal material of the car body can block the error signal and electromagnetic radiation to a large extent. Even if it is used for a long time, it will hardly affect people. It can be ignored, but if it is placed in the car, the impact will be severe. We have had clients before, experienced and tested them firsthand. As a result, after 40 minutes, he himself said that his eyes were blurry and his head was a little swollen. Therefore, we strongly demand that the high-power cell phone jammer antenna must be installed on the roof (outside the car) and the host of the shielding device. It can be installed in the car and connected to the external antenna through the RF feeder.
