Recently, I discovered that every time I drive to a gas station, I find that my mobile phone has no signal and cannot be used normally. It turns out that a mobile cell phone jammer is installed at the gas station. Why is this happening? Gas stations need radio waves to make calls, which may cause serious events such as explosions, so gas stations have installed cell phone jammers to prevent calls. This is a necessary tool to provide a safe environment. But I think this is for safety reasons, because we often see warnings that gas stations do not make any calls. This may give you an idea of ​​why you need to install jammers at gas stations.

Similarly, the use of jammers anywhere has its purpose. On the one hand, it is used as an installation of school jamming equipment to prevent students from using mobile phones in the classroom, and on the other hand, to prevent them from cheating in exams. The installation of mobile phone jammers in movie theaters allows people to have a pleasant viewing experience. The installation of mobile phone jammers in libraries creates a quiet learning environment for students. Gas stations pay more attention to safety.
