Passive cellular interception solution for mass off-air interception of 2G communications. Its ruggedized design is ideal for rough environments and weather conditions. The Passive interception system collects target or mass cellular communication data in wide areas of interest and analyzes communications in real-time. It then filters out irrelevant calls, identifies links between targets and notifies operators of potential targets.

The Passive interception system works independently of service providers and helps f ield forces to identify potential targets – it then builds the related intelligence picture, without interfering with 2G networks or mobile phones and without leaving any electromagnetic trace. Moreover, to conform to privacy limitations, the Passive interception system can be configured to collect only CDRs and generate alerts based on suspicious communication patterns.

After collecting the traffic, the Passive interception system filters though thousands of communications using embedded speaker identification, link analysis and text analysis engine technology.
