Airvana Brings the 'Sound of Music' to Mobile World Congress 2010

Musical 'mashups', connected families and the fastest femto all to feature in Barcelona

BARCELONA, Spain, February 11 - MOBILE WORLD CONGRESS 2010 — Airvana, Inc. (Nasdaq: AIRV), the company
transforming the mobile experience, will showcase its HubBub(TM) UMTS
femtocell solutions at Mobile World Congress 2010 with full working
demonstrations. In addition to a unique audible demonstration of the
capabilities of its enterprise product, Airvana will be outlining the
potential of its high-speed consumer femtocell to create a new mobile
applications and services platform.

The femtocell is a small device that plugs into a standard broadband
connection and creates a personal in-home (or business) mobile network. It
provides full 'five-bar' 3G mobile phone reception throughout the home or
office and multi-megabit data connections, all without impacting on the
capacity of the mobile operator's radio access network. Femtocells give
operators the opportunity to minimize customer churn and attract new
customers with guaranteed in-building voice and data coverage and compelling
applications and services.

Airvana will be giving the following demonstrations:

Musical mashup

Music will be streamed from an Airvana enterprise femtocell to 16 mobile
handsets simultaneously, to create a wireless symphony. The demonstration
will showcase the femtocell's capabilities in a demanding multi-user
environment.

The family tablet

A touch screen, femtocell connected tablet based application, designed
with the busy family in mind. The demo will feature a range of social,
multimedia-based services designed to keep the family 'location aware' and
fully connected. An Android-based mobile phone app, operating on the Google
Nexus One device, will also be demonstrated that enables family members to
remotely interact with the family tablet via the femtocell.

Airvana's fastest femtocell yet

Airvana's latest generation HubBub femtocell is proven five times faster
on average than typical indoor macro network performances. 'Buffer-free' HD
video will be streamed live to a mobile handset simultaneous with other
applications, to illustrate the HubBub's data transfer capabilities.

The demonstrations will be take place on Stand: AV91 at Mobile World
Congress, Barcelona.

In addition, as a founding member of the Femto Forum, Airvana will be
taking an active role in the industry group's 'Femtozone' showcase in Hall 1,
Stand 1G19. The Femtozone will feature a daily schedule of public
presentations from operators, vendors, analysts and other industry bodies on
the major opportunities and challenges facing the femtocell market. The
