Infineon´s 3G Mobile Platform Solutions Start to Commercialize

Munich, Germany and Hong Kong, China – November 19, 2004 – Infineon Technologies AG (FSE/NYSE: IFX), a leading supplier of semiconductor solutions for the wireless industry, on occasion of the 3G World Congress & Exhibition in Hong Kong announced the availability of its 3G mobile platform that supports UMTS, EDGE and GPRS cellular standards. Infineon also announced that an Asian handset manufacturer has selected Infineon as a strategic partner and cooperates with respect to terminal platform development.

The 3G platform, which is displayed at the 3G exhibition, features an ARM9 based modem and is based on Infineon´s S-GOLDT baseband controller family and UMTS radio frequency (RF) transceiver SMARTi®U. Furthermore, the platform uses Infineon´s W-CDMA protocol stack as well as the APOXI® application framework. Together with network operators and network vendors the protocol stack´s performance was tested successfully in interoperability tests, conformance tests, and field trials in numerous countries. The W-CDMA protocol stack is also available as a dual mode EDGE/W-CDMA version. The platform uses a W-CDMA baseband processor from Broadcom.

SMARTi®U is the world´s first high volume single-chip W-CDMA RF transceiver IC for single-mode UMTS and dual-mode UMTS/GSM cellular handsets. Its robust design together with highest performance made it the solution of choice for numerous designs in the market.

APOXI® (Application Programming Object-Oriented Extendable Interface) application framework facilitates the reuse of applications over several product generations. It provides an open application protocol interface (API) thus enabling easy integration of third party applications, such as WAP (Wireless Application Protocol) browsers and MMI (Man Machine Interfaces). Major applications such as WAP, MMS, Java, Voice Recognition, Email and SyncML are available through an extensive partner network.

The 3G platform offers several upgrade possibilities towards multimedia options, such as video streaming and video telephony, allowing mobile manufacturers to flexibly design phones tailored to different market segments. The basic software and hardware components of the platform remain the same when adding options, independent of the cellular standard. Mobile phone manufacturers benefit from reduced development times, fast time-to-market and better adaptability to design trends.

The WCDMA platform solution is 3GPP Rel99 compliant and features packet switched data speed of 384 kbit/s in up- and downlink.
