I am a bit worried because the problem of cheating is also a topic of using smartphones. Cheating seems to happen at the same time as the examination system starts, but due to the rapid development of electronic communication technology, the means seem to be more and more diverse. On the other hand, we are taking measures such as prohibiting the carrying of mobile phones and considering using metal detectors. Among them, some products have attracted people’s attention, cell phone jammer , it is a mobile phone radio wave control device that blocks mobile phone radio waves.
In fact, it applies not only to university entrance exams, but also to qualification exams, high school entrance exams, national exams, etc. This means that cheating on mobile phones is very common. This is the most effective way to prevent cell phone cheating by installing a cell phone jammer at the test site. A wireless station license is required to install the device. By sending a weak radio wave of the same frequency as the radio wave of the notification information from the mobile base station, communication is suppressed.
The number of people who want to be able to use mobile phones in hospitals is increasing, but there is no doubt that it is absolutely necessary to ensure a safe environment, and there is a problem of lifting the ban on mobile phones in hospitals. The mobile phone jammer approved by the Ministry of Internal Affairs and Communications as an experimental station will also be used in actual experiments in hospitals. This is a deterrent device that has the function of making the mobile phone “stop service” in a specific space to protect medical equipment Free from malfunctions caused by the electromagnetic waves emitted by mobile phones.
