Mobile jammers are becoming more and more diverse

I am a little worried because there is a lot of discussion about jammers due to the canning problem with smartphones. I tried to enter the actual question in the mobile email. This is a lot of work. The canning behavior seems to occur at the same time that the examination system is started, but due to the rapid development of electronic communication methods, this method seems to be becoming more and more diverse. On the other hand, we have taken measures such as prohibiting carry-on, considering the use of metal detectors, and checking the names of people going to the toilet. Among them, some products have attracted people's attention. It is a mobile phone radio control device that blocks radio waves. This product is a device that blocks mobile phone radio waves by emitting special blocking radio waves.
The device not only prevents unnecessary calls on mobile phones, but also prevents emergency calls from public agencies. But we have the right to protect our privacy. This product is a way to protect yourself. Therefore, everyone should use a mobile cell phone jammer. This product is now easily available. This jammer is very effective in many places. You need to use the product reasonably. When using, you must abide by the law and use GPS circuit breakers. It is expected that there will be almost no life experience and self-centeredness, making people unable to think of the importance and harmlessness of using mobile phones.
The safe use of mobile jammers is very important. There are also precautions when using it. All antennas must be connected before powering up. In Japan, blocking radio waves without the permission of the Ministry of Internal Affairs and Communications may violate the Radio Law, so please consult the Ministry of Internal Affairs and Communications before using it in Japan. The accessory antenna of each carrier is separate, so please be careful when installing.
