Qualcomm Successfully Demonstrates Fully Mobile VoIP Calls Across a Number of Field Test Environments

More Than 60 Calls per Sector Show Commercial Readiness of CDMA2000 1xEV-DO Rev. A VoIP Services

SAN DIEGO - June 07, 2006 - Qualcomm Incorporated (Nasdaq: QCOM), a leading developer and innovator of Code Division Multiple Access (CDMA ) and other advanced wireless technologies, today announced it has successfully demonstrated the full mobility of high-quality, high-capacity voice over Internet protocol (VoIP) calls across multiple test environments, including mobile, pedestrian and fixed, enabling operators to migrate voice services to Internet protocol (IP)-based platforms for a common service platform. The field tests, which involved 62 simultaneous calls, were conducted over CDMA2000® 1xEV-DO Rev. A in one sector within a single 1.25 MHz channel - in a fully mobile configuration. The test network demonstrated capacity gains approximately 30 times greater than mobile analog voice and results from a fully loaded commercial network could be somewhat lower. Qualcomm used commercial-ready application specific integrated circuits in both handset and prototype networks. These field tests validate the quality and capacity of full mobility VoIP over EV-DO Rev. A and pave the way to large scale commercial trials by network operators.

“Operators globally have committed to the rapid deployment of CDMA2000 EV-DO Rev. A. These tests prove EV-DO Rev. A's capability for delivering high-capacity, high-quality VoIP over 3G mobile broadband networks,” said Dr. Roberto Padovani, chief technology officer of Qualcomm.

VoIP over EV-DO Rev. A leverages session initiation protocol, commonly referred to as SIP, in combination with a number of advanced techniques to achieve quality of service comparable to traditional landline voice. These techniques include:

The full mobility success of these VoIP field tests represent another step toward the convergence of IP and mobile data services with landline wide area IP networks, as Qualcomm helps bring its customers' IP Multimedia Subsystem (IMS) strategies to fruition. Operators will be able to efficiently merge their wireless and wireline networks based on IMS, allowing them to realize unsurpassed cost and operational efficiencies over current deployments. By basing all communications services on an IP network, operators are able to use their network capacity in a much more flexible manner, through the dynamic allocation of capacity to an ever-increasing array of 3G services, such as:

“Qualcomm is committed to innovating on the 3G roadmap and will drive the leading edge of airlink enhancements converging onto one IP interface,” said Padovani. “High-capacity, full-mobility VoIP is a significant milestone in this vision for the evolution of mobile broadband networks. It will enable operators to supercharge their service packages by offering customers a rich mix of voice and data, and end users will have a heightened multimedia experience from the resulting realtime audio, video and data streams their service providers offer.”
