Airvana to Showcase Live Broadband Internet, VoIP, Push-to-chat, and QoS over 1xEV-DO at CDMA Americas Congress 2004

Chelmsford, MA, September 29, 2004 —  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-chat and IP QOS over 1xEV-DO during the 2004 CDMA Americas Congress in Miami, September 28-30, 2004. Airvana will also provide attendees the opportunity to experience VoIP and Broadband Internet access over 1xEV-DO first hand at Airvana’s Internet Café.

These demonstrations will highlight the benefits of Airvana’s 100% 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-Chat – Airvana will display the superior performance of Push-to-Chat 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 utilizes QChat technology licensed from Qualcomm.

· 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 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-Chat.

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.
