Portable SDR-Based Catcher

The system is designed to collect basic identities (IMSI, IMEI) of mobile phones in the working area (airport terminals, prisons, etc.) regardless of the mobile standard.

The basic unit of the system is an SDR module which can communicate in any RAT: GSM, UMTS or LTE. It creates a fake BTS (Node) with the best operation parameters so that mobile devices in the area will connect to it. When the mobile phone tries to register with the Node, it reveals IMSI, IMEI identities and some detailed information about its communication capabilities. As soon as required information is collected by the catcher unit, the mobile phone can be released to the provider’s network or passed onto our active monitoring system to collect more intelligence such as voice calls, SMS and packet data.
