Bangalore: Subex Systems, Bangalore-based telecom software Products Company, on May 29, announced that it has signed a contract with leading mobile operator Bharti Cellular, to deploy its flagship Fraud Management System, Ranger.

Ranger aids wireless and wireline telecom carriers to curb fraud through the use of innovative subscriber profiling techniques and advanced analytical capabilities, a Subex statement said announcing the contract.

With the Bharti's order, Subex's Ranger has been deployed in all the major Indian private mobile operators, including Hutch, Idea Cellular and BPL Mobile, it said.

The statement quoted global studies which revealed that telecom operators lose as much as 10 per cent through revenue leakage and about 40 per cent in terms of churn leading to substantial loss of revenue and profits and additional cost of acquisition and retention of subscribers.
