GSM Interceptor ( WideBand)
MULTICHANNEL SYSTEM FOR RADIOMONITORING OF SIGNALS IN GSM
CELLULAR COMMUNICATION NETWORKS
The GSM interceptor WB system is intended for passive radio interception of GSM cellular
communication sessions that support A5/1, A5/2 encryption algorithms.
THE SYSTEM CONSISTS OF:
1. Signal reception and processing unit
2. A5/1 deciphering unit
3. Operator’s workstation based on a laptop
4. Specialized software
5. Omnidirectional magnet mount antenna 7dB, for GSM signal reception
6. Omnidirectional magnet mount antenna 3dB, for embedded GSM modem
7. GPS magnet mount antenna, for determining the system location
8. Antenna amplifier for directional antenna
9. Directional antenna 12 dB with bracket for mounting on a mast, for improving the quality of
low-power Uplink signals reception
10. Power inverter 12 V / 220 V (DC/AC)
11. GSM mobile terminal with NetMonitor feature
KEY AND DISTINGUISHING FEATURES:
• Fully passive GSM interception
• Wideband multiband receiver
• Possibility of several SRPUs to operate with one A5/1 deciphering unit
• Support of diversity reception
• Possibility to record all GSM sessions coming from controlled GSM base stations
• Possibility of quick search and listening to the sessions of nearby located subscribers
• Possibility of deceleration/acceleration of playback of voice data without modifying the
voice tone
• Possibility of operating in a distributed configuration that makes it possible to build
branched radio monitoring networks covering large territory
• Possibility to work in continuous automatic mode without operator’s intervention.

• External Interface: Ethernet.
Operator workstation (OWS):
• Processor: Intel Core i7 (quad-core);
• RAM: 8 Gb;
• SSD: 750 Gb.
FUNCTIONAL CAPABILITIES:
• search and identification of Base Transceiver Station (BTS) control channel numbers of
communication networks in full working frequency range;
• collection and displaying of technical and statistical information about communication
networks with detailed indication of parameters for each BTS;
• displaying of radio frequency environment in the point of current location;
• operational evaluation of received signal strength and quality at all receiving channels;
• displaying of messages passing through control channels of BTSs and mobile stations;
• selection of controlled targets with use of both constant (IMSI, IMEI, IMEISV) and
temporary (TMSI) identifiers;
• selection of targets by Classmark;
• selection of targets by the specified range of distances from BTS;
• support of a signaling protocol for SDCCH/8 and SDCCH/4 channel formats;
• capability of operating both in the Realtime mode and in the Delayed mode with recording
all the data received onto a disc and next session reconstructing;
• playback of speech in real time with possibility of automatic switching to any of the
assigned traffic channel;
• viewing of text messages (SMS) and USSD;
• decryption of A5/1 and A5/2 algorithms in real-time;
• storing of all records in the database with possibility of multi-user remote access;
• intercepting of direct and reverse (under sufficient signal strength) traffic channels;
• support of HR, FR, EFR, AMR-FR, AMR-HR, AMR-WB speech codecs;
• support of Hopping mode;
• processing of handover of traffic channels between BTSs;
• maintenance of data bases for all the information accumulated during system operation
(voice messages, SMS, number information and service messages);
• displaying of DTMF symbols being dialed during the call;
• match making between a subscriber number MSISDN and a system identifier IMSI/ TMSI
used by a network by active search of targets;
• access to system functional capabilities is possible only after user authorization;
• system’s software includes a separate shell that is intended for working with databases and
that is capable to function independently of the hardware;
• system’s software can be interfaced with Navitron geoinformation system for storing GPSinformation
and displaying the particular objects on vector maps;
• system’s software runs in Windows XP / Windows Server 2003 / Windows 7 / Windows 8
environments.
