Portable IMSI / IMEI / GSM / 4G LTE / Catcher passive monitoring sistem

System requirements. The system must support FR, EFR, HR, AMR voice codecsThe system automatically handles Frequency Hopping and HandoversMapping of service provider BTSs on the digital map System must provide the distance of the target from its serving BTS based on timing advance parameter of GSM network . Must be achieve Passive GSM Monitoring SystemGSM Network Interception of GSM communications encrypted using A5/1 and A5/2 ciphering algorithms in [login to view URL] be able to Intercept Voice and SMS along with Call Related Information like protocols from 850/900/1800/1900 MHz GSM network in passive mode100% Passive system and presence of the system cannot be detected by anyoneCan Monitor upto 16 target cell phones simultaneously (not less then 4) and provides both sides communication(Full Duplex)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)Logging of intercepted Voice and SMS along with call related and protocol information on hard disk of the Laptop.On-Line listing of the cell phone callsAutomatically detects the ciphering algorithms used on the network in real-time. Possibility of finding TMSI/IMSI/IMEI of a known MSISDN number Switching ON/OFF the recording of conversations, network information and other parameters Display current status of receivers (ideal/ monitoring / scanning).Possibility of round-the-clock operation in an auto mode without the operator involvement .Simplicity of maintenance, which does not require a deep knowledge, either in the field of computers, or in the field of cellular communication systems for the operator. To be designed and developed as a Passive of-the-air GSM Monitoring System. The Surveillance of U interface (b/w M BTS and Mobile Handset) must provide total traffic monitoring of the target phone. The System must use technology for deciphering of A5.1 and A5.2 cipher algorithms. Must be capable of intercepting and deciphering of voice conversation from standard GSM800/900/1800/1900 MHz cellular network. Along with the Voice and SMS traffic system also intercepts and display the protocol information which can be used by the operators for the deep analysis of target data. MUST be equipped with multi-channel receivers which can be independently tuned to any GSM BTS irrespective of the service provider.
