Mobile phone blocking devices are becoming more and more popular and are used to protect public places, businesses, personal privacy protection and more.Therefore, mobile phone jammers generally do not interfere with emergency calls.Emergency calls actually use different signal frequencies.In fact, this is a misunderstanding.In fact, at the entrance of some libraries in life, you may find a sign that says "Mobile phone signal is blocked".
Recently received a complaint at a library.It shows that there are signal jammers installed inside, and the learning atmosphere there is generally better than other libraries that do not have signal jammers installed, which is one of the reasons I support the installation of signal jammers; another reason is that some people think that mobile phone jammers It will block emergency calls.But some people have different views.When the mobile phone leaves the shielding range, the mobile phone can be used normally.
Some have suggested installing Cell phone signal jammers in libraries to stop rude people from answering calls in libraries.What do you think about the use of distracting devices in libraries? Do you support it? In fact, I think it is very good to install mobile signal jammers in the library to create a quiet reading and learning environment for readers.Still others believe that libraries should not limit readers' freedom to communicate on their mobile phones.
Due to the jammers installed in some areas of the library, some people think that it may affect emergency calls.Many people get annoyed when their cell phone rings while reading a book.In order to ensure the quietness of the building, it is recommended that the administrator spend hundreds of dollars to purchase a mobile phone signal jammer and install it in the library.It is a jamming device that can block GSM/3G/4G/5G mobile phone signals and prevent the library from receiving calls.
Therefore, there is no need to worry about this.Many people react differently to new technology.But there are also different opinions.Many people think that it will block emergency calls.Therefore, it is not allowed by the laws of many countries.Some people answer the phone loudly in the library, with no regard for other people's feelings.Repeated persuasion still did not work.But citizens reacted differently to installing cell phone jammers in libraries.
