How do GSM interceptors work and its types!

In today’s time, cellular Interceptions & cellular monitoring technologies indeed provide LEAs and Government Agencies with a technological edge. It is via cellular interception, that users can attain Communications Intelligence (COMINT) which aids various authorities to secure, investigate, and control intercepted wireless communications like voice and data.

Hence, in the battle against terrorism and criminal activities, a real-time GSM interception system was created to offer world-wide government and law enforcement societies with the most valuable spectrum interrogation tool. Today, several Law Enforcement surveillance users go for the updated GSM Interception Systems with communication control and forensic attributes.

What is a GSM Interceptor & how does it work?

A GSM interceptor is an equipment that can collect information from hundreds of phones across targeted vicinities and can intercept conversations and messages & execute ‘denial-of-service’ attacks on phones. Hence, a GSM Interception system works by breaking the GSM encryption algorithm during real-time communications that secure cellular phones on a GSM cellular service network.

Knowing the types of GSM Interception Systems via Stratign!

a) Stratign’s Active GSM Interception System

The evolution of GSM technology along with augmented technological attributes and heightened complexity presents Stratign with a competitive environment to fabricate and construct solutions to provide a complete ‘Off-The-AIR Communication Surveillance System’ to diverse Government and Intelligence-Gathering clients. The Semi-Active GSM Interception System has a universal operating capability. This system can be utilized to intercept communications globally, from any GSM service-providers, irrespective of the type of encryption being exercised. In the active mode, the system imitates the cell-phone tower making it to act as a genuine unit and influences the target’s mobile phone to register with it.

Product Features:

    • Capable of Interception and logging of all GSM, 3G and 4G Bands.
    • Configurable number of channels starting from 04 channels to 16/32 channels
    • Interception of GSM communications in real-time: Encrypted in A5/1 and A5/2 Ciphering algorithms.
    • Automatic tuning of the Receivers: Holds a possibility to scan and recognize control channels & communication system boundaries.
    • The System does not necessitate the service provider’s SIM for operation.
    • The system can monitor all communications of the target (Voice, CRI, Location) till the time it is within the coverage range.

b) Stratign’s Passive GSM Interception System

The Passive GSM Interception System from Stratign is a ‘multi-channel tunable’ GSM Monitoring system. Each receiver is self-reliantly connective & tunable to any BTS of the GSM Network. This system from Stratign is meant to guarantee interception and deciphering of audio conversation from standards such as GSM-850/900/1800/1900MHz Cellular network in a static or in a mobile-environment. The Passive systems can be easily integrated with an active 3G/4G unit to downgrade the communication to 2G for interception of 3G and 4G networks too.

Product features:

    • A configurable number of channels starting from 04 channels to 16/32 channels.
    • Automatically identifies, decodes the ciphering algorithms utilized on the network in real-time. It also records mobile phone conversations,
       call-related data & network-information to the hard-disk of the system.
    • Ability to scan GSM network parameters in the restrained area (Service Provider, Broadcast Channel Number, Cell IDs, Signal Levels).
    • Possibility of full-time operation in an auto mode without any involvement from the operator.

c) Stratign’s Hybrid GSM Interception System

The Hybrid GSM Interception system from Stratign is a combination of Passive and Active subsystems. Both the passive element and the active element of the system can work in synchronization. The passive component can be utilized to investigate missions, while the active component can be utilized to support the target-based interception. This makes the system more discrete and difficult to detect.

Product features:

    • The passive system can operate on all the four GSM bands: 850/900/1800/1900MHz
    • System’s ability to integrate with active 3G and 4G Nodes
    • Configurable number of channels starting from 04 channels to 16/32 channels

In conclusion, Stratign’s GSM Monitoring solutions are wholly integrated, compliant and portable systems which can be conveniently moved and implemented for critical mission-based circumstances. These GSM Monitoring systems offered by Stratign can be customized to fit in your existing vehicle or vehicle of your choice to intercept the target while moving.
