Active GSM Monitoring System

Active GSM Monitoring System

The Active GSM Monitoring System (AGMS) can target connected devices using A5.2 or A5.0 encryption. Depending on the configuration of the host network and specific target device, it is also possible to monitor and record conversations using A5.1 encryption. The AGMS enables the operator to gain full control of all incoming and outgoing conversations of the monitored mobile phones, as well as providing powerful search and filtering options in order to locate the targeted devices. All incoming and outgoing calls are recorded and stored onboard, and it is also possible to establish direct contact with the targeted devices, either by cellular telephone voice call or text message. Direct contact communications can also be recorded. Unlike the passive monitoring systems, the AGMS supplies extensive information about the monitored devices, such as IMEI, IMSI, telephone number, and more (details withheld – please enquire for further information). It is completely undetectable by the host network and it operates near-invisibly. Direction finder and device locator accessories are available to extend the utility of this device, enabling a specific device to be tracked – even in populated areas. The AGMS includes the network access station (dual-band), the BTS unit (radio cell) and the laptop with the controller software. Depending on the application area and network quality, one or two single-band BTS units may be necessary.
