The appearance of mobile phone jammers is to prevent excessive use of mobile phones. It prohibits the use of mobile phones by reducing the frequency of mobile phones and cell tower base stations, and loses the ability to make calls and send information within the effective frequency range. People within the interference distance will not be disturbed by loud calls and maintain a calm mind. Finally, signal handheld jammer can be used in conference rooms, auditoriums, courts, libraries, examination rooms, schools, cinemas, theaters, hospitals and other places where telephones are used.
