AudioCodes, Brix Networks and Camiant Participate

CHELMSFORD, Mass., Sept. 13, 2006 (PRIMEZONE) — Airvana, Inc.
(, an innovator and leader in mobile broadband
infrastructure based on 3G mobile broadband technology, today
announced that it has established a 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. Current
participants include AudioCodes, Brix Networks and Camiant.

“As operators make the important shift to all-IP networks, it is
imperative that voice quality is not compromised by competing data on
the network,” said Vedat Eyuboglu, CTO of Airvana. “To that end, the
VoIP Lab demonstrates Airvana’s commitment to ensuring that Rev. A
performs to its promised standards.”

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.

“QUALCOMM believes that the VoIP Lab is an important step in making
sure that Rev. A delivers voice quality that is actually better than
the current circuit-switched technology,” said Chris Davey, VP of
Sales for QUALCOMM. “We are pleased to see vendors participating and
look forward to the technological enhancements that the VoIP Lab will
generate for Rev. A.”

Current VoIP Lab participants comment:

— AudioCodes ( “As an industry leader
in providing converged, IMS-ready VoIP media gateways and media
servers, AudioCodes is pleased to have our CDMA-enabled Mediant VoIP
media gateway in Airvana’s VoIP Lab,” said Rich Poole, director
business development for AudioCodes. “Airvana’s VoIP lab should help
to accelerate the availability of market-ready Rev. A solutions for
service providers.”

— Brix Networks ( “We are in the business
of providing converged service assurance solutions to our customers,”
said Kaynam Hedayat, vice president, engineering and CTO of Brix
Networks. “Working with Airvana allows us to have synchronicity and
mutual advancement with other members of the Rev. A community.”

— Camiant ( “Camiant aims to align network
applications with network resources,” said Susie Kim Riley, founder
and chief technical officer for Camiant. “Since Airvana supplies Rev.
A infrastructure, it is critical that we participate in the VoIP
Lab’s simulation of real network conditions so that operators have
few, if any, problems when they match services with their networks.”
