ND-IG001 GSM Interception System


ND-IG001 GSM Interception System is a wideband monitoring and interception system designed to monitor cellular communication systems, displaying information in real time as well as saving it for future analysis.


Basic Tasks:

• Wideband receiver monitors cellular network on 900/1800 or 850/1900MHz

• Create recorded communication sessions in Data Base

• Evaluate the current status in targeted zone, detect the registration of the

• BS stations and display their parameters

• Fast search and complex filtering by specified parameters of requested data from the records in Data Base

• Control of the system by remote terminal via Internet or LAN interface

• Decipher voice conversation, SMS messages & DTMF codes in real time

• Identify the communication sessions and registration for the parameters of the target phones

• Statistical and structural filtering and analysis of all the monitored results

Cellular Interception System


• Based on the DDC (Digital Down Converter) wideband adaptive digital receiver

• Receiver can function in any pair of frequency ranges (850/900 or 1800/1900 MHz)

• Enables operation with up to 256 simultaneously controlled communication sessions.

• It can control simultaneously function of close to 48 different BTS or operators

• The average rate of the concurrently intercepted voice calls, text and data in the typical operation case in average is in the range of 40-60 conversations but can reach up to 256 calls

• The receiver logic provides effective distribution of resources and flexible adjustment to operator tasks

• “Black List” function allows isolate specific phones from the interception by the System
