AMPLITEC Distributed mobile signal precision shielding system Low loss

The distributed mobile signal precise shielding system consists of a SAMU signal acquisition host unit, a HUB optical signal expansion unit, and an ISTU interference signal transmission unit. It is a system that uses new digital scrambling technology to achieve precise shielding of mobile signals in designated areas. It collects mobile phone signals in a designated area through a collection antenna and transmits them to SAMU. SAMU uses a new digital scrambling technology to analyze and re modulate each modulated signal through software defined radio technology, generating corresponding interference codes. Then, it performs channel coding modulation and outputs them to the downlink output to HUB. HUB converts the interference signal into an optical signal and transmits it to ISTU through optical fiber. ISTU converts the received optical signal into an interference signal and transmits it to the target area, making it impossible for mobile phones in the target area to communicate with the base station normally, achieving the purpose of blocking communication. Its biggest feature is that it only needs to output a signal power 2-6dB higher than the environmental base station signal to achieve the effect of shielding mobile phone signals. It has the advantages of green low radiation, full standard high efficiency, and precise perimeter control.
