Airvana, Inc. (www.airvana.com), an innovator and leader in mobile broadband infrastructure based on 3G mobile broadband technology, today announced it made the industry’s first Quality of Service (QoS) enabled mobile-to-mobile VoIP call on a commercially available EV-DO Rev. A network.  Airvana demonstrated the call in its Multimedia/VoIP laboratory.

“We are pleased to have reached this significant industry milestone,” said Vedat Eyuboglu, CTO of Airvana.  “VoIP is a highly delay-sensitive application, and delivering VoIP over an IP-based wireless infrastructure requires sophisticated QoS techniques.  Our demonstration of VoIP on Airvana’s QoS-enabled commercial EV-DO Rev. A network infrastructure is a significant step towards commercial VoIP services over EV-DO Rev. A.”

Specifically, Airvana made mobile-to-mobile VoIP calls using handsets based on QUALCOMM’s MSM6800^TM baseband ASIC and software to establish QoS-based calls over delay-sensitive/low-latency flows in a commercial-grade Rev. A network.  EV-DO Rev. A supports multiple QoS flows per handset each with its own unique QoS requirements.  This capability allows VoIP and other multimedia traffic to receive higher priority over other best-effort traffic, such as web, email, and file transfer traffic.

“QUALCOMM is pleased to see Airvana’s VoIP Lab succeed in this critical demonstration,” said Roberto Padovani, CTO for QUALCOMM.  “Rev. A promises to deliver a new breed of performance on CDMA2000^® networks, and the VoIP Lab serves as a viable proving ground for operators preparing for Rev. A upgrades.”

About the VoIP Lab

Airvana established its Multimedia/VoIP laboratory to test and demonstrate commercial IP-based mobile broadband 1xEV-DO Rev. A and fixed-mobile convergence systems.  The VoIP Lab seeks to identify issues that may arise when voice and other multimedia data packets converge on a single network.  From Quality of Service (QoS) to individual call performance, the VoIP Lab will help ensure that wireless VoIP networks run as flawlessly as possible.

The VoIP Lab has three categories of testing and demonstration: applications, technical performance and capacity.  Applications testing will evaluate live VoIP calls with QoS on a mixed-load network; technical performance testing will measure enhancements to symmetry and reductions in latency; and capacity testing will demonstrate the full commercial viability of the simultaneous voice/video/data triple play.  Over time, Airvana will continue to invite applications vendors to demonstrate advanced VoIP applications.
