The Semi Active off-the-air GSM Monitoring System is designed using cutting edge technology to intercept Voice and SMS from GSM 2G, 2.5G, 3G and 4G/LTE/5G cellular networks. The system supports standard GSM, 3G and 4G/LTE/5G frequency bands including 850/900/1800/1900 MHz.The system is equipped with state of art A5.1 hardware decryptor and A5.2 software decryption module to decrypt the intercepted communication in real time. Depending upon the customer requirement, system can be configured to intercept several GSM phones from multiple GSM service providers simultaneously. The standard configuration of the system can monitor 12 phones simultaneously from 5 different service providers.

The system is packed with some advanced features which allow displaying the approximate location of the target on map. System can plot its own location on map, location of service providers BTS as well as the approximate location of the target. The display of approximate location of the target on map provides a fair idea about location which can further be tracked by using handy GSM DF to locate him in a multi-storeyed building or in a crowded place. Along with the interception of traffic from target phones, system has capability to jam specific services of selected /all phones in its vicinityandwillnot allowthem to communicate.
