In my spare time, watching a game quietly, going to the cinema to watch a science fiction movie, or going to the theater to enjoy a wonderful musical is a very relaxing thing, but the appearance of the phone Broke this rule. We know that many people now use their mobile phones without any time, no matter what the occasion. When we quietly enjoy the musical, suddenly being interrupted by the ringing of the mobile phone will make people very angry.
Most people who listen to musicals know that keeping quiet in the theater is a basic requirement, especially mobile phones, must be muted or turned off. However, not everyone will fully abide by these guidelines. We can often hear people's voices and noises there. For those who love music, this is a disaster.
Now, finally there is a way to keep the theater quiet, that is to install the wifi blocker. The wifi blocker perfectly shields all mobile phone signals in the field, including WiFi signals, so that all mobile phones are in a network-free state, unable to connect or make calls.
Calling anywhere, anytime does make us very convenient, but in some places, the phone using can be very annoying, and even cause some serious negative effects, such as cinemas, conference centers, churches, etc. Not all people will follow these guidelines, and their loud calls without restraint will cause serious harassment to others.
WiFi blockers have been used in many applications. For example, examination rooms are used to prevent cheating in exams. Hospitals are used to prevent certain signals from affecting the normal use of medical devices. Some professional departments use them to prevent hackers from stealing datas. In some meeting rooms, the confidential room is used to ensure the quietness of the meeting room and the privacy protection of the meeting content.
