Cell phone jammer to suppress the inconvenience of ringtones
In recent years, with the rapid popularity of mobile phones, smart phones have become convenient because they can answer calls anytime, anywhere. On the other hand, in public places such as movie theaters, cell phone ringtones can cause trouble to others. It seems difficult to maintain the space for watching movies. There is a movement to prevent inconvenience caused by ringtones and the like by using jammers that have the function of suppressing mobile 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 interference devices.
There is an example of introducing jammers in the lobby. During the playback process, there is a phenomenon that someone’s cell phone will ring continuously. Even if you receive the prompt "Please turn off your phone before the show starts", this phenomenon will not decrease. Therefore, I used anti-interference equipment in the lobby to avoid inconvenience to others. This device is intended to eliminate radio waves from mobile phones in this area. Since the mobile phone radio controller emits stronger radio waves at the same frequency as the mobile phone base station, assuming it is a radio wave from the base station, the mobile phone will receive the radio wave of the 3G/4G phone jammer.
It is also planned to install jammers around the ATM. In each row, posters were posted around the ATM to prohibit the use of mobile phones. In order to prevent transfer fraud, we have introduced a device that prevents the use of mobile phones around ATMs to protect citizens’ valuable assets.
Due to the rapid development of electronic communication methods, the behavior of canning seems to become more and more diverse. There is a phenomenon that you can pass the test by using a mobile phone or a small earphone to canned it. If you use your mobile phone to refill cans, we decided to introduce a device that can block the mobile phone's radio waves to prevent this phenomenon from happening. By using this device, this device generates radio waves of the same frequency as the mobile phone, making the mobile phone unusable.
It is unpleasant to use the phone in places where you can't talk (such as subways or restaurants), so I use gps jammer devices to activate the wifi jammer and make it unusable. When I was reading on the subway, people around me started tapping my phone. I want to know if the interfering device is turned on without knowing it, but the power is turned off properly.
However, the use of these communication suppression devices (such as mobile phones) requires a license, so be careful when using communication suppression devices. According to the Radio Law, when opening a radio station, you must obtain permission from the Minister of the Interior and Communications, except for broadcasts that emit weak radio waves. Certain requirements must be met, such as assigning wireless workers who meet the qualification requirements.
Mobile phones are very convenient because you can answer calls anytime, anywhere. On the other hand, if you accidentally connect, you will be connected even if you don't want to be connected. It can be said that with the popularity of mobile phones, GPS jammers have become more and more necessary.
