22 Dec SMJ1890 – Prison solutions
Up to 200W Adjustable Output Power/Band
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.
