Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to an indoor mobile communication interference equipment. Background technique [0002] In the field of communication, a signal is a physical quantity that represents a message. For example, an electrical signal can represent different messages through changes in amplitude, frequency, and phase. Interference is the impairment of the reception of useful signals. Interference generally consists of the following two types, crosstalk: the coupling phenomenon between two signal lines in electronics. Radio interference: The act of disrupting communications and blocking broadcast station signals by sending radio signals to reduce the signal-to-noise ratio. [0003] Nowadays, signal interference technology is widely used indoors, mainly for various examination rooms, schools, gas stations, courts, prisons and other places where the use of mobile phones is prohibited, which...
