The SMJ1890 was designed for blocking GSM cellular network and all kinds of cellular standards in the world. The SMJ1890 uses state-of-the-art technology for maximum performance. The unit is controlled by a microprocessor for PPL & DDS programming.The unit was designed with the capabilities of jamming specific channels inside the cellular networks bands only. Additionally, jamming of downlink & uplink is possible at the same time. The unit is based on a DDS that can be programmed to transmit up to 36 channels per band, by fast-sweeping between each other. The channel bandwidth is 250 KHz.The user can control the output power of each band via a programmable attenuator.Output power can vary from 5W to 100W within 1dB steps. The SMJ1890 transmits noise signal, which cuts-off all cellular communication between mobile phones and cellular base stations. The jamming radius depends on the signal strength in a given area. All cellular mobiles in proximity to the SMJ1890 will be totally blocked and will not be able to receive or dial outgoing calls.Applications. Prisons Military Units, Special Police Units, Governmental Facilities, Sensitive Areas System Features, Jamming up to 60 channels inside the cellular band. Easy to use programming interface.
