The system is completely passive and contains no transmitting part. Neither GSM operator nor mobile phone user is able to detect such type of interception. The system consists of four main parts: Receiver Unit Notebook Computer with special software and A5/2 real-time decipher, A5/1 real-time decipher Antenna. Standard configuration of the Receiver Unit has 16 receivers, 8 for forward channels and 8 for reverse channels. It means that the system is capable to intercept up to 8 concurrent duplex calls and cover up to 8 BTS.
