"Today Corsair's PhonePrint system is the recognized leader in cellular fraud prevention," said Tom Meyer, Corsair Communications' president and chief executive officer. "This award highlights the technical depth of our engineering team, which integrates RF technology, real-time computer systems design, and the ability to develop and operate a worldwide network providing roaming protection for cellular systems." The PhonePrint system uses a combination of hardware and software technologies to identify, validate, and disconnect so-called cloned cellular phones before charges can be incurred. Each cellular phone has a series of unique characteristics, enabling an "RF fingerprint" to be created in Corsair's database. Soon after being installed in cellular sites, the Corsair PhonePrint system disconnects fraudulent calls in real time, and has virtually eliminated cloning fraud in the United States. Typical implementations have reduced cloning fraud dramatically within 3-4 months. While new digital authentication technologies have helped diminish the impact of cloning for newer cellular companies, phone cloners continue to victimize rural operators in the U.S. and elsewhere through roaming fraud. Even as digital (TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). , GSM, and CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. ) standards dominate new wireless construction, the industry continues to support a large base of analog phones and infrastructure in the U.S., Asia, and Latin America. According to Corsair's Meyer, "While the United States has seen a steady decline in cloning fraud since PhonePrint was implemented throughout the A and B-bands in the U.S., Mexico, and the Carribbean, carriers in Latin America and Asia continue to be victimized by this crime and appear to be looking to PhonePrint as a solution. This situation may represent additional growth for Corsair and opportunity to extend the PhonePrint footprint worldwide."
