Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced that the Company has successfully demonstrated push-to-talk (PTT) initial call set-up performance of less than two seconds over CDMA2000 infrastructure and handsets between dormant mobiles, with its QChat technology. Qualcomm's QChat solution uses voice over Internet protocol (VoIP) technologies to enable ubiquitous, efficient and virtually instantaneous PTT functionality on wireless devices based on CDMA2000 and other CDMA 3G networks. Compared to other server-based solutions, QChat performs extremely fast call set-ups while minimizing use of the operator's radio resources. Many competitive PTT solutions trade radio spectrum assets for call set-up performance.

QChat is an end-to-end solution for the delivery of PTT-related services and includes client software for wireless devices and a sophisticated distributed server platform that provides scalable, highly available and reliable services.

The QChat client is deployed as an application on Qualcomm's Binary Runtime Environment for Wireless™ (BREW™) platform and is the only PTT functionality that offers dynamic, over-the-air upgrades of handset software, management of group membership by subscribers and ad hoc creation of chat groups.

The highly scalable QChat Application Server (QAS) enables a wireless operator to efficiently deliver millions of PTT calls over a large geographical area. The QAS can be deployed in a distributed fashion, taking advantage of regional dispatch calling patterns, while maintaining carrier-grade reliability and manageability.

"Wireless operators require a solution to address the challenges of delivering a profitable push-to-talk service," said Dr. Paul E. Jacobs, group president, Qualcomm Wireless & Internet Group. "With a strong systems approach, QChat will provide that level of performance and a rich set of functionality for operator's push-to-talk customers."

Qualcomm is continuing discussions with CDMA operators outside the United States regarding QChat and to date has signed memoranda of understanding (MOUs) with two operators. Qualcomm expects to announce commercial trials and demonstrations of QChat in the second half of this year.
