In recent years, with the rapid popularity of mobile phones, smart phones are very common because they can answer calls anytime, anywhere. On the other hand, in public places such as movie theaters, ringtones such as mobile phones often cause other people’s troubles, and it is difficult for people to maintain a comfortable space for watching movies. There is a cell phone jammer to prevent trouble caused by ringtones and so on.
In order to maintain a quiet environment and prevent harmful mobile phone radio waves, we have installed mobile phone jammers in many places. For example, in the broadcast hall, there will always be the phenomenon of someone’s mobile phone ringing. Even if you receive the prompt “Please turn off the power of the mobile phone before the performance starts”, this phenomenon will not be reduced. Therefore, in order not to disturb others, I used a mobile phone signal interference device in the lobby. Since the cell phone blocker emits stronger radio waves at the same frequency as the cell phone base station, the cell phone considers the radio waves emitted by the jammer to be radio waves from the base station.
With the rapid development of electronic communication technology, cheating seems to be diversifying. During the test, there was a phenomenon of using mobile phones or small headphones, wearing watches and other tools to cheat. In order to prevent this phenomenon, we decided to introduce a device that can cut off the radio waves of the mobile phone. By using this device, this device will make the mobile phone unusable by generating radio waves of the same frequency as the mobile phone.
When I use the phone in subways, restaurants, or other places where calls are forbidden, I feel uncomfortable, so I use a cell phone jammer and remove it from the service area. When I was reading on the subway, the people around me started to be busy with cell phones.
