  1. RADIUS GSM MONITORING SOLUTION

  2. System purpose The system is intended for search, interception, recording and analysis of communication sessions, as well as service information in GSM cellular communication networks. • Voice interception • SMS interception • Service messages interception and manipulation

  3. System components 1. Signal reception and processing unit (SRPU) 2. Rod antenna 7dB 3. Rod antenna 3dB 4. Control notebook 5. GSM modem 6. Power inverter (AC/DC) 7. Directional antenna 8. Antenna amplifier

  4. Key features • Fully passive GSM interception • A5/1 and A5/2 real-time decrypting • Can operate with table of targets or intercept in random mode • Capability to link a few SRPUs in intercepting network • All records are stored in MySQL DB with capability of remote access to them; • Support of Hopping mode; • Processing of handover of traffic channels between BTS;

  5. Technical characteristics • Supported bands: GSM 850, R-GSM 900, DCS 1800, PCS 1900; • Quantity of duplex channels in real-time mode: 18, 36 or54; • Antenna inputs: 2; • Receiving path sensitivity: -105 dBm; • SRPU external interface: Ethernet 10/100 Мbit/s; • SRPU power supply: 220V ± 10%, 50 Hz;

  6. A5/1 deciphering unit features • High efficiency, a short time for key calculation; • Certification as per the MIL-STD for military use and use in aircraft and vehicles; • Low power consumption, low noise level; • Possibility to link several units into a cluster for enhancing performance; • External interface – Ethernet;

  7. A5/1 deciphering unit engineering data • Average performance for key calculation: 2 keys/sec(up to 12); • Power supply: AC 90…260V, 45…65Hz, DC 12V military grade; • Power consumption: 75W during calculating and 20W in idle mode; • Weight: 1.8Kg; • Size: 35 x 15 x 5 cm • Operating temperature: 0ºC…50ºC (-10ºC… 70ºC if stored);

  8. Interception Capabilities Networks scanning GSM Base Station GSM Base Station GSM Base Station GSM Base Station

  9. Interception Targeted Acquisition GSM BTS GSM BTS GSM BTS GSM BTS

  10. Interception Interception and processing of information GSM BTS GSM BTS GSM BTS GSM BTS

  11. Interception Interception of Voice & SMS GSM BTS GSM BTS GSM BTS GSM BTS Voice SMS

  12. Real-time mode Delayed mode • Delayed mode features: • Work without decryptor, decryption initiates after connecting the A5/1. • Interception all information from frequency channels of reachable BTS • Unable to track targets if they move to BTS that not assigned on a mission • Real-time mode features: • Real-time decrypting of the A5/1 and A5/2 encrypted sessions • Interception of all data from logical GSM channels of reachable BTS • Able to follow a target that movesand changing service cells

  13. Analyzing intercepted data All intercepted data is stored in the DB • Specialized SW gives wide capabilities to process intercepted data: • Export of audio and TXT files • Wide retrieval criteria’s • Link analysis • Data correlation • Remote access
