Technology will allow operators to gain experience with 4G-like services

Chelmsford, MA, July 26, 2007 — Airvana, Inc. a leading provider of network infrastructure products used by wireless operators to provide mobile broadband services, today announced it has successfully completed a multi-carrier CDMA2000 1xEV-DO Revision B (Rev B) call in its development laboratory, a major step towards commercialization.

“Multi-carrier EV-DO will enable operators to deliver a new generation of bandwidth–hungry applications,” said Vedat Eyuboglu, CTO of Airvana. “By leveraging their Rev A hardware investment, operators can start gaining experience with 4G-like services at a fraction of the capital investment required to build 4G networks.”

Extends Mobile Broadband Leadership With UMTS Pico and Femto Cell Pioneer

Airvana, Inc., a provider of network infrastructure products used by wireless carriers to provide mobile broadband services, announced it has acquired 3Way Networks, a provider of home base stations and industry-tailored solutions for UMTS markets. Terms of the deal are undisclosed.

The acquisition furthers Airvana’s strategy to address UMTS radio access networks and to deliver fixed-mobile convergence and in-building mobile broadband solutions for both UMTS and CDMA2000 markets. 3Way Networks’ pico and femto cell solutions will complement Airvana’s Universal Access Gateway (UAG), a high-capacity network element through which we expect to provide secure access to core network services for UMTS, CDMA2000, Wi-Fi and other Internet Protocol (IP)-based wireless devices.

“This is a logical step in both companies’ evolution,” said Simon Albury, managing director of 3Way Networks. “We believe the acquisition validates our technology, and provides 3Way Networks with considerable resources and market reach.”
