What year it was a Fierce 15: 2004
Why it was a Fierce 15: Airvana's innovative technology allowed CDMA carriers to launch 3G 1xEV-DO networks that use all-IP infrastructure. This meant that 3G networks could accommodate more data. Airvana's IP structure also made it easier for carriers to manage their networks, and could even allow them to launch new services such as VoIP through their cellular networks. Airvana's network equipment partners included Nortel Networks and Ericsson. Click here for more.
What has happened since it was awarded the Fierce 15: Airvana continues to provide IP-based wireless network infrastructure products to wireless operators that want to deliver mobile broadband. These products include EV-DO base stations, radio network controllers, network management systems, femtocells and universal access gateways. In May 2007, Airvana acquired 3Way Networks, a pioneer of femtocells for UMTS markets. Airvana's products currently are used by more than 70 operators worldwide, and the firm has partnerships with Alcatel-Lucent, Hitachi, Motorola, Nokia-Siemens Networks, Nortel, Pirelli Broadband Solutions, Qualcomm and others. In July 2007, Airvana launched an initial public offering of 8.3 million shares priced at $7 per share for a total of $58.1 million. The company scored a big win in July when it signed a master supply agreement with Sprint Nextel for 3G femtocells.
