Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today began offering attendees to CTIA Wireless 2005 in New Orleans the opportunity to see live demonstrations of the significant improvements in wireless services enabled by CDMA2000® 1xEV-DO Rev A. Qualcomm will be demonstrating such converged IP-based (Internet protocol) capabilities as VoIP (voice over Internet protocol) services over EV-DO, EV-DO Rev. A higher data rates, pilot interference cancellation (PIC), and Platinum Multicast. These leading capabilities enable wireless operators to cost-effectively offer a wide variety of compelling voice and data services tailored to segmented user needs. Qualcomm's demonstrations can be seen at Booth Number 2631, Hall C, at the CTIA show March 14-16.

“With Rev. A, the capabilities of CDMA2000 1xEV-DO continue to set the benchmark for wireless wide area IP Systems,” said Dr. Paul E. Jacobs, Qualcomm CEO-elect. “The rich variety of multimedia and IP-based services — both voice and data — enabled by Rev. A will allow our handset, infrastructure and operator partners to drive the competitive landscape as the convergence of mobile wireless, computing and consumer electronics change consumers' high-tech lifestyles around the globe.”

Support for VoIP Services
Operators implementing Rev. A throughout their network will be able to take advantage of wireless IP-based capabilities and enjoy the cost and flexibility advantages of an IP-based system well into the future. Operators choosing this development path will benefit from economies of scale and high-volume cost curves which take advantage of IP network elements and distributed network architectures. The ability to offer VoIP services over Rev. A-based networks will profoundly enhance operators' service offerings by enabling the combination of high-quality voice with a wide variety of applications, such as interactive 3D gaming among large groups of players, instant messaging with full multimedia content and video telephony.

Also, over Rev. A the IP airlink, resources can be used more flexibly — e.g., downloading high-quality multimedia content to user devices overnight while using the airlink resources for VoIP and interactive high-speed data applications during the day. This means operators will realize an improved use of spectrum and network flexibility by being able to tradeoff capacity and QoS capabilities, as well as monetizing high-speed data during voice idle times.

Rev. A Higher Data Rates & Higher Capacity
Rev. A offers improved peak data rates on both the forward and reverse links. On the forward link, peak data rates increase to 3.1 Mbps, while reverse link peak speeds have increased to 1.8 Mbps. Rev. A offers higher sector capacity within the same 1.25 MHz carrier, allowing operators to support more users and richer applications. Rev. A has twice the sector capacity of Release 0 on the reverse link and 1.2 times sector capacity on the forward link. Rev. A is fully backward compatible and interoperable with deployed EV-DO networks and devices around the world. Moreover, it builds on previous EV-DO enhancements, which enable operators to offer exciting new services and significantly differentiate their wireless offerings from their competitors.

Pilot Interference Cancellation

Qualcomm continues to find new approaches to increasing system capacity and network efficiency for CDMA-based networks - all the while lowering operating costs for service providers. PIC employs advanced techniques to reduce interference on the CDMA reverse link. It improves the reverse link capacity by removing the pilot interference, which improves the signal-to-noise ratio. By removing pilot signal interference, an operator can increase capacity by an estimated 15%-20% for VoIP applications. Future products supporting Rev. A will introduce full interference cancellation, thus approaching the ultimate theoretical capacity of a multiple-access reverse link.

Platinum Multicast

Platinum Multicast is proposed as the next evolutionary step of EV-DO multicast technologies. Platinum Multicast provides an extremely cost-effective method for wireless operators to deliver a multitude of video and audio channels to a large subscriber population over Rev. A-based cellular networks coupled with a content delivery system such as the MediaFLO media distribution system, with more than three times the capacity of Gold Multicast. This higher capacity translates into more channels of content or higher resolution content with the same number of channels. Higher capacity also results in a proportionately lower cost per bit transferred over the air. Operators who deploy Rev. A networks will have the ability to offer Platinum Multicast with a software upgrade. This smooth migration path enables EV-DO operators to stay at the forefront of offering the highest-performance and lowest-cost cellular services with broad appeal to mass consumers.

Rev. A is supported by Qualcomm's CSM6800 and MSM6800 chipsets. Rev. A features are backwards compatible to earlier CDMA-based systems thereby preserving operators' initial CDMA system investments - providing operators a low risk migration path for existing systems.
