HONG KONG, Nov. 16, 2004 (PRIMEZONE) -- Airvana, Inc. (www.airvananet.com), a provider of All-IP, third-generation (3G) CDMA2000 1xEV-DO infrastructure, will demonstrate live Broadband Internet access, VoIP, Push-to-Talk and IP QoS over 1xEV-DO during the 2004 3G World Congress held in Hong Kong, November 16-18, 2004.

These demonstrations will highlight the benefits of Airvana's 100 percent IP-enabled infrastructure in delivering high-speed wireless data services to mobile professionals, VoIP subscribers, residential broadband users and consumers of multimedia information and entertainment.
-- Push-to-Talk - Airvana will display the superior performance
of Push-to-Talk when offered over a 1xEV-DO network. From
exceptionally fast call setup times (around 1 second) to
reduced latency and higher capacity, the use of 1xEV-DO for
PTC services offers significant efficiency improvement over
1xRTT. The high-performance demonstration uses QUALCOMM's
QChat(r) Push-to-Talk product, which QUALCOMM and Nextel
Communications Inc. (NASDAQ:NXTL) are working together to
develop.
-- VoIP - Airvana's All-IP 1xEV-DO infrastructure provides an
optimal solution for the delivery of VoIP. Broadband data
rates, QoS mechanisms, and native support for IP to facilitate
the transport of packet voice without degradation of voice
quality.
-- QoS - Airvana's QoS mechanisms give network priority to
subscriber traffic flows based on the operator-assigned
service level. With the ability to differentiate services in
this way, carriers may offer tiered, high-margin services to
premium level customers. Such services include video
conferencing, multimedia downloads, VoIP and Push-to-Talk.
Service providers are deploying CDMA2000 1xEV-DO worldwide as a high-speed mobile data service for cell phones, PDAs and laptops. It is flexible enough to support mobile applications or act as a low cost, fixed wireless broadband data service. 1xEV-DO can also be deployed very inexpensively, either by upgrading an existing base station with a channel card or by overlaying the existing network with low cost CDMA2000 1xEV-DO base stations. With an overlay solution, CDMA, TDMA, GSM and new "Greenfield" operators all can all enjoy the revenue opportunities of 1xEV-DO.
