Radio Signal blocker Jamming
The reason for the source of radio signal interference is the accumulation of history. As early as the early stage of economic reform, the radio management policy was transferred from military management to local government management. The gradual opening ofsignal jammer use made it into civilian use, and various management regulations were established one by one. As the economic system changed from a planned economy to a market economy. The continuous deepening of the radio industry, like other businesses, has developed rapidly.
Great changes have taken place in people's ideas, and the original regulations cannot meet the management requirements. Driven by economic interests, some units and individuals use radio stations without authorization, especially individuals who use high-power cordless phones and radio and television agencies to expand transmitters without authorization. Interference events caused by output power occur frequently.
