In recent years, with the rapid popularity of mobile phones, smart phones are very convenient because they can answer calls anytime, anywhere. On the other hand, in public places such as movie theaters, in many cases, the ringtones of mobile phones and the like can cause annoyance to other people. It seems difficult to maintain a relaxing space to watch movies. There is a movement that prevents inconvenience caused by ringtones by using a cell phone jammer with a function of suppressing cell phone calls.
In order to maintain a quiet environment and prevent annoying mobile phone radio waves, we have introduced mobile phone radio wave blocking devices in many places. I will briefly introduce an example of installing interfering devices. There is an example of introducing jammers in the lobby. During the playback process, there is a phenomenon that the ringtone of someone's mobile phone will keep ringing. Even if you receive the prompt "Please turn off your phone before the performance starts", this phenomenon will not decrease. Therefore, in order not to disturb others, I used an annoyance device in the lobby. This device is intended to eliminate radio waves from mobile phones in this area. Since the mobile phone radio control device emits stronger radio waves at the same frequency as the base station of the mobile phone, assuming it is a radio wave from the base station, the mobile phone will receive the radio wave of the 3G/4G mobile phone jammer.
