Recently, there are many people who have used smartphones. Many have the right to have the freedom of communication. Freedom of communication means that the people have the right to freely use communication means such as letters, telegrams and telephones. However, there is a phenomenon in which this right is abused. I have a cheat problem using a mobile phone in a recent exam. There is also a phenomenon such as wire fraud at a financial institution using a mobile phone. In many halls, it is common to see mobile phones ringing and interfering with viewing. In order to prevent inconvenience caused by ringtones of smartphones, etc., it is necessary to promote public welfare such as ensuring quietness in a specific space. We allow the installation and operation of mobile phone jammers.
As for out-of-service devices for interfering with radio waves such as smartphones, special devices that make them unusable within a certain area are attracting attention. Consideration is given to installing this device so as not to violate the freedom of communication. The right to use mobile phones, etc., and the right to prevent inconvenience caused by communication with mobile phones, etc., seem to be in direct conflict with each other, and I do not know for sure. Freedom to use mobile phones seems to be an important individual right, and the use of nuisances can be said to lead to public welfare.
At the same time as the right to use the freedom of communication, it is also important to bother others. Don't violate the rules. Using a mobile phone for college entrance exams violates the rules. We cannot guarantee the fairness of the exam. There is also a risk of damaging the rights of others. Therefore, it is legitimate to install a jammer to prevent cheating. This is an effective method. It is legitimate to install this wifi signal jammer in public places to prevent inconvenience caused by ringtones of mobile phones. This is the maintenance of public welfare. It can be almost impossible to take advantage of high quality communication. This also belongs to the scope of the management right of the facility manager and has nothing to do with the freedom of communication.
