With the rapid development of electronic communication methods, cheating seems to be more and more diverse. During the test, there was a phenomenon of using a mobile phone or a small headset to cheat and pass. In order to prevent this phenomenon, the incident of repeated cheating using a mobile phone occurred, so we decided to introduce a device that can cut off the radio waves of the mobile phone. With this device, this device generates radio waves of the same frequency as the mobile phone, making the mobile phone unusable.
On the 10th and 10th subway restaurant, because this should not be, if you are using a mobile phone, the original call using the interfering device becomes an unpleasant place, such time is to use the signal jammer, our out-of-service service is given to. While studying on the subway, people around me started talking on the phone loudly. I want to know if I turn on the interfering device without I knowing it, and then turn it off.
However, the use of these communication suppression devices (such as mobile phones) requires a license, so be careful when using signal suppression devices. According to the Radio Law, radio stations must obtain permission from the Minister of the Interior and Communications, except for radio equipment that emits weak radio waves. Certain requirements must be met, such as assigning wireless workers who meet the eligibility requirements. Mobile phones are convenient because they can answer calls anytime, anywhere. On the other hand, inadvertently will cause you to want to stay connected. It seems that with the popularity of mobile phones, the demand for signal jammers is also increasing.
