Definition of interfering device: Interfering device is a device that emits radio waves. Its frequency band is the same as that used by mobile phones. Therefore, mobile phones, etc. cannot be used in the vicinity where the device is installed. This is a disturbing thing. After installing this machine, mobile phones, etc. will not be within the scope of repair. You will not be able to make or receive calls.

Reasons to use mobile phones
During this time, with the rapid spread of smart phones, etc., I felt uncomfortable with the ringtones of mobile phones in cinemas, cafes, museums, and concert halls. There are many situations that cause inconvenience to others. Have bad behavior, such as filling cans with mobile phones at the test site. Produce unfair results. In addition, important information may leak in sensitive areas such as military bases and government agencies. It is also necessary to provide a comfortable environment for patients in the hospital. Using a wifi jammer can prevent ringing and talking on the phone, prevent canning, prevent the leakage of privacy and confidential information, and prevent radio noise.

principle:
By blocking the radio waves from the base station, the mobile phone and the base station cannot be connected normally, and the terminal cannot be used. The phone is disabled. It is said that this will temporarily prevent you from making and receiving calls.
