Airvana  has founded a Multimedia/VoIP laboratory to test and demonstrate commercial IP-based mobile broadband 1xEV-DO Rev. A and fixed-mobile convergence systems.
The announcement of the establishment of the lab was simultaneous with news of three other collaborations aimed at improving the quality and performance of VoIP and other IP-based services (see story ).
Proponents of Rev. A assert the technology is capable of supporting carrier-grade VoIP (see New CDMA revision promises carrier-grade VoIP ), but that it will have to be actively assured. The VoIP Lab seeks to identify issues that may arise when voice and other multimedia data packets converge on a single network. From quality of service (QoS) to individual call performance, the VoIP Lab will help ensure that wireless VoIP networks run as flawlessly as possible.
Airvana has combined advanced CDMA2000 1xEV-DO broadband technology with an IP-Radio Access Network architecture. Airvana's largest deployments are Verizon Wireless , Sprint PCS , Bell Mobility , and Telus .
