Qualcomm products mentioned within this press release are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

Vodafone Ltd. and Qualcomm Incorporated (NASDAQ: QCOM) today announced the completion of their field trial to demonstrate Code Division Multiple Access (CDMA) wireless access integrated into a Global System for Mobile Communications (GSM) network. The primary objective of the trial was to demonstrate compatibility between the CDMA (IS-95) air interface and an existing GSM network through integration of an unmodified GSM switch at the GSM-standard A-interface. The trial successfully demonstrated the technical feasibility of GSM-CDMA integration while maintaining CDMA over-the-air performance.

During the six-month trial many integration tests and performance measurements were conducted and documented. Key GSM services and features tested include voice calls, Short Message Services (SMS), call forwarding, call transfer, call waiting and authentication. The trial mobile phone software includes integrated GSM software supplied by The Technology Partnership (TTP) based in Melbourn, UK.

Qualcomm and Vodafone are planning to hold a series of Open Days in February in Newbury, UK, where a final report on the trial results will be made available. In addition to the technical trial results, Qualcomm will present business and economic information related to the hybrid GSM-CDMA technology. As stated at the commencement of the trial, the findings are to be made widely available to the mobile communications community for use in evaluating enhanced wireless technologies.
