With the rapid development of electronic communication methods, cheating seems to be more and more diverse. In the exam, there is a phenomenon of cheating with a mobile phone or a small headset and passing the exam. Due to the repeated use of mobile phones to cheat, in order to prevent this phenomenon, we decided to introduce a device that blocks mobile phone radio waves. With this device, this device generates radio waves of the same frequency as the mobile phone, making the mobile phone unusable. There is also an example of installing a mobile cell phone jammer around an ATM. Posters are posted around ATMs on each line, prohibiting the use of mobile phones. In order to prevent transfer fraud, we have introduced a device to prevent the use of mobile phones around ATMs as a measure to protect citizens’ valuable assets.
For devices that are out of service, such as smartphones that interfere with radio waves, special devices that make them unusable in certain areas are attracting attention. This equipment should be considered to avoid infringing on the freedom of communication. The right to use mobile phones, etc., and the right to prevent inconvenience caused by the use of mobile phones, etc., seem to be in direct conflict, and I am not sure. The freedom to use mobile phones seems to be an important personal right, and it can be said that the use of nuisance leads to public welfare. While enjoying the right to communicate freely, it is also important to disturb others. Don’t break the rules. Using mobile phones for college entrance examination violates regulations. We cannot guarantee the fairness of the exam. There is also the risk of harming the rights of others. Therefore, it is legal to install deterrent devices to prevent cheating. This is an effective method. This mobile phone jammer prevents the inconvenience caused by mobile phone ringtones in public places
