Wideband Passive GSM Monitoring System

GSM cell phone intercepts have been one of the key systems utilized by Intelligence agencies for Passive Intel acquisition. Available GSM Intercept technology always had a drawback on coverage area as well as number of targets intercepted. Shoghi’s New Wideband Passive GSM Interception System is a Big GAME Changer in this domain. With a coverage range of upto 50 kms , interception of all 1024 GSM sessions from 128 frequency channels and 30 BTSs  , Real time Decryption etc. makes this an absolute must have technology for all Intelligence Community.

Wideband Passive GSM Monitoring System (SCL-5020WB) has been designed to intercept the entire GSM traffic within its coverage range from GSM-900, DCS-1800, 3G and 4G network. System can intercept up to 1024 GSM sessions simultaneously from 128 frequency channels and 30 BTS. SCL-5020WD is 100% passive and its presence cannot be detected by anyone. It provides processed human intelligible traffic in the form of Audio, SMS and USSD content along with Call Related Information. With a high gain antenna, system provides up to 50 km of interception range on downlink communications (from BTS to Mobile station) and up to 600m interception range on uplink communications (from Mobile station to BTS) subject to the network topology, buildings and other conditions. System is equipped with unique feature, which displays its own location as well as the service area of operators BTSs on digital map.

Simultaneous monitoring of 1024 sessions provides intelligence agencies a means to collect and analyse the GSM traffic from a suspicious area in order to identify the potential suspicious targets. System uses state of the art technology for real-time deciphering of A5.0, A5.1 and A5.2 cipher algorithms and provides human intelligible content.

SCL-5020 is equipped with operator workstation application, which allows the operators to listen the call, and view the SMS on user-friendly graphical user interface. Any two calls can be listened in real time while rest of the calls will be recorded in the system, which can be accessed by the connected operators.
