Mobile phone jammers installed at gas stations prohibit calls

With the development of science and technology, with all kinds of anti-theft and theft after retrieving the device, you can easily surf the Internet. Although you have a lot of devices, there are also many opposite tools that allow you to take protective measures. It doesn’t work, so it’s safer to park it downstairs at your home, and it’s not always possible to stay downstairs. Yes, I have the same problem, but I think it 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 cell phone jammer at gas stations.

My child is addicted to wifi network and plays games with his mobile phone or tablet. I want to cut off the wifi signal and make it unable to access the Internet. How can I stop? Also 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 the gas station has a mobile phone jammer installed. 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. The use of jammers in any place has its uses. On the one hand, it is used as an installation of school jamming equipment to prevent students from using mobile phones in class, and on the other hand, to prevent them from cheating in exams. Gas stations pay more attention to safety.
