Chelmsford, MA, March 18, 2003 —  Airvana Inc. (www.airvananet.com), a provider of All- IP, third-generation (3G) CDMA2000 1xEV-DO infrastructure, today announced that it has been selected as a member of FierceWireless' annual list of "The Fierce 15", honoring the company as one of the top 15 wireless startups for 2004. FierceWireless, an internationally recognized email newsletter covering the wireless industry, evaluated more than 1,200 privately held wireless companies based on company vision, revenue potential, quality of deals and partnerships, and competitive position.

"Airvana's 3G networks can accommodate more data, which means carriers can offer more data services," said Stephen Wellman, Editor of FierceWireless. "Thanks to the strength of its technology and partnerships, Airvana is perfectly positioned to take advantage of this year's 3G rebound."

Airvana's CDMA2000 1xEV-DO is an "always on" mobile wireless technology that enables data to be sent over PCS and cellular wireless networks at broadband speeds, and at a cheaper cost per byte than any other 3G technology. Subscribers can connect to a 1xEV-DO network using a 1xEV-DO mobile phone or by connecting their mobile phone or PC card to a laptop or PDA. Users experience speeds comparable to cable and DSL services and are able to use all popular business, information and entertainment applications without any modifications. The technology can be added to existing CDMA2000 base stations with a simple channel card upgrade or layered on existing CDMA, TDMA and GSM networks.

"FierceWireless is recognized for its advanced understanding of wireless trends and businesses," said Randy Battat, president and CEO of Airvana. "Being selected as a member of The Fierce 15 is an honor that highlights Airvana's growing prominence in the wireless market."

The Fierce 15 celebrates the spirit of being "fierce" - daring to be innovative and aggressive, even in a difficult market. The list of Fierce 15 companies is available in today's issue of FierceWireless and on the FierceWireless Web site at http://www.fiercewireless.com.
