Airvana Successfully Completes Multi-Carrier CDMA2000 1xEV-DO Rev B Call
CHELMSFORD, Mass., 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."
Rev B multi-carrier EV-DO is the natural evolution from Rev A, supporting significantly higher per user throughput by multiplexing traffic across multiple carriers. Such multi-carrier multiplexing delivers a significant reduction in data latency when compared to Rev A systems serving the same users on the same carriers. After a software upgrade to a Rev A radio network, operators can launch services utilizing peak speeds of 9.3 Mbps on the forward link and 5.4 Mbps on the reverse link using three 1.25 MHz-wide carriers. This represents a 3x improvement over Rev A in the actual end user experience, which will significantly improve the end user experience when running rich multimedia applications, such as high definition video streaming and music downloads. Further gains are possible in future, as the Rev B standard supports peak data rates of 14.9 Mbps on the same 3 carriers and 73.5 Mbps by aggregating 15 1.25 MHz carriers within 20 MHz of bandwidth.
Rev B multi-carrier EV-DO is part of the CDMA2000 1xEV-DO Rev B standard, and is fully backward compatible with existing Rev 0 and Rev A devices. Additionally, Rev B multi-carrier EV-DO's benefits are not limited to new multi-carrier devices. By upgrading their Rev A networks to multi-carrier EV-DO, operators will be able to boost the user data speeds for Rev A and Rev 0 users by reducing the overall load on the radio network. Multi-carrier EV-DO is also expected to allow operators to increase the number of Rev A VoIP and push-to-talk users they could serve without affecting the experience of data users.
Airvana expects to begin operator trials of Rev B multi-carrier EV-DO in Q3 2007.
