GMS Monitoring Products - Specifications

5G GSM Network Interception System

  • Semi-Active type of the IMSI/IMEI collection algorithm.

  • Automatically scans and detects parameters of all 5G networks.

  • Detects all 5G phones and redirects them on 4G, 3G, 2G networks.

  • After redirecting to a 3G network, it can display the phone's model number, country of origin and the name of the service provider.

  • Measures distance of redirected phones to 3G network with the accuracy of less than 30 m.

A53 Downgrader

  • Downgrade the A5.3 encryption to A5.1 encryption on chosen BTSs of the service provider's network in the area of operation

  • Can perform mass down gradation of A5.3 to A5.1

  • Uses proprietary complex algorithms to downgrade the A5.3 to A5.1 encryption

  • Can downgrade up to 16 base stations

  • Device designed to use with any passive GSM system, allowing to downgrade the ciphering from A5.3 to A5.1, which could be easily deciphered

Passive GSM Monitoring System

  • Can monitor 850/900/1800/1900 MHz GSM network

  • Completely Passive monitoring system and presence of the system cannot be detected

  • Can be used for monitoring / interception of upto 32 target cell phones simultaneously and provides full duplex communication

  • Can intercept the Targets by different parameters such as IMEI, IMSI, TMSI, Target distance from the base station, Type of target handset, Target's Dialed & Received number (PLMN)

  • GSM Interception System will provide the distance of the target from its serving BTS based on timing advance parameter of GSM network

  • GSM Monitoring System can map service provider BTS on Google map

  • Can be integrated with 3G & 4G modules for interception of Voice and SMS traffic from 3G & 4G/LTE networks

Wideband Passive GSM Monitoring System
