GTReS – GSM Traffic Recording System

GTReS is a multi-band fully passive GSM interception system designed to record the entire traffic occurring between Base Transmitting Stations (BTS) and Mobile Stations (MS) located within the system’s operational range. This means literally tens or even hundreds of simultaneous calls. 

“Fully passive” means that:
  • GTReS does not have any transmitting parts;
  • GTReS does not interfere with GSM networks and mobile phones; 
  • GTReS’ operation is completely undetectable. 

Recorded information can be processed either on-line or off-line.

GTReS can intercept:
  • Voice communication;
  • SMS messages;
  • Primary and secondary DTMF tones;
  • Call related information

Deciphering capabilities

The system supports both types of encryption implemented in GSM networks – A5/1 and A5/2.

A5/2 real-time decipher is a software based solution; it works as a background application. Average deciphering time is 15 msec.

A5/1 decipher is a separate device connected directly or remotely to the GTReS. For more information about A5/1 deciphering, please refer to the RTDM51 description.
