Multi-band fully passive GSM interception system - MGI
GSM Traffic Recording System
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:
MGI does not have any transmitting parts;
MGI does not interfere with GSM networks and mobile phones;
MGI’ operation is completely undetectable.
Recorded information can be processed either on-line or off-line.
MGI can intercept:
Primary and secondary DTMF tones;
Call related information
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 5 msec.
A5/1 decipher is a separate device connected directly or remotely to the MGI. For more information about A5/1 deciphering, please refer to the RTDM51 description
We recommend to use with MGI quick decipher (up to 24 keys per sec)
Added module of global geolocation of subscribers (optional)
