It analyzes the downlink dedicated channel of the base station to obtain the baseband signal, then reorganizes it as an interference code to shield the downlink interference signal of the mobile phone. This product confidently supports the shielding of mobile phones of different standards without causing any interference to the uplink of the base station. Within the shielding area, it effectively blocks mobile phone communication services of various operators, including voice, data, SMS, and other services.
