MUNICH, and MILPITAS, Calif. -- Infineon Technologies AG (FSE/NYSE: IFX), a leading supplier of communications products, and Kineto Wireless, Inc., the key innovator and leading supplier of Unlicensed Mobile Access (UMA) technology, succeeded in bringing together two innovative technologies that will facilitate the rapid delivery of mobile and fixed Internet Protocol Multimedia Subsystem (IMS) services across a broadband Wi-Fi access network. The companies demonstrated several IMS-based applications using UMA technology to show the seamless handover between mobile and Wi-Fi access networks.

IMS is the open, standardized IP multimedia and telephony core network specification for mobile and fixed operators that is defined by 3GPP (3rd Generation Partnership Project). UMA is the 3GPP global standard for Mobile/Wi-Fi convergence that enables mobile subscribers to roam and handover between cellular networks and WLANs using multi-mode mobile handsets.

The demonstration consisted of Infineon’s IMS client for mobile phones, operating with Kineto’s UMA client on a GSM/GPRS/EDGE-WiFi handset platform. The demonstration showed how UMA provides session continuity of IMS-based presence and push-to-talk applications when the handset platform passed between a live GPRS network and Wi-Fi connection.

With UMA, mobile phone users of media-rich IMS services can benefit from the higher speed and lower latency of Wi-Fi access networks to achieve improved application performance. With multi-megabit data rates, Wi-Fi offers a true broadband experience for IP multimedia services. Operators and handset manufacturers preparing to launch IMS in early 2006 can benefit from the higher performance capabilities of the UMA access network.

“Infineon is heavily focused on realizing a world of seamless communication. IMS technology will form the heart of the converged service network and UMA technology will bring the cost and performance advantages of Wi-Fi access to mobile networks,” said Dr. Christian Mucke, vice president of Infineon’s Mobile Software business unit and managing director of Comneon GmbH & Co. OHG, the wholly owned wireless software subsidiary of Infineon. “Combining the complementary strengths of Kineto’s market leadership and best-of-breed UMA client solution for handsets with Infineon’s best-in-class IMS software is a large step forward for the future of converged services.”
