We will briefly introduce examples of installing interference equipment. There are some examples of introducing jammers in the music hall. During playback, there is a phenomenon that someone's mobile phone rings. Please turn off your phone before the show starts. "However, this phenomenon has not decreased.
Therefore, in order to avoid disturbing others, we use anti-cell phones in the lobby. The device is designed to keep mobile phone radio waves in the area out of the service area. Since WiFi cell phone jammers emit stronger radio waves at the same frequency as mobile phone base stations, mobile phones will receive radio waves from 3G / 4G phone jammers like base stations.
When installing this device, care should be taken not to hinder the freedom of communication and the right to prevent inconvenience caused by mobile phone communication. The two seem to be directly opposed. The use of jammers will affect the public interest. While enjoying the right to freedom of communication, it is important to disturb others. In many places, it is legal to install a wifi jammer to prevent cheating in exams.
