ORLANDO, Fla., March 27, 2007 (PRIME NEWSWIRE) -- Airvana, Inc. (www.airvana.com), an innovator and leader in mobile broadband infrastructure based on 3G wireless IP packet data technology, today announced a new 1xEV-DO Radio Access Network (RAN) based on a collapsed or "flat" architecture. This new "flat RAN" will make mobile broadband networks more reliable, more flexible, easier to engineer and deploy, and less costly to operate by reducing the number of network elements required to build 1xEV-DO networks.
Airvana's flat-architecture RAN combines the functions of a base transceiver station (BTS), radio node controller (RNC) and packet data serving node (PDSN) into a single node. This dramatically simplifies network deployments, and reduces the probability of network outages by eliminating the need to re-configure multiple hierarchical network elements each time a new node is added. It also transforms the economics of service expansion by freeing operators from the need to invest in high-cost centralized network elements in advance of subscriber demand. It is built based on software modules that can be ported to proprietary or standards-based OEM hardware platforms and is an important step on the path toward 4G type architectures.
"Airvana's flat architecture platform is based on the expertise we've built in the areas of IP, broadband and mobile wireless technologies," said Randy Battat, president and CEO of Airvana. "By delivering our capabilities under this new architecture, we are broadening the addressable market for advanced EV-DO-based services."
The flat-architecture RAN is ideally suited for difficult-to-serve environments, such as enterprises, campuses, hot spots and even temporary sites such as public events or public safety operations. It can also be used for new deployments of standard commercial mobile broadband services, for example, extending coverage into rural areas. The product draws upon the extensive features and field-proven performance of Airvana's existing EV-DO products and is optimized for demanding applications requiring high bandwidth, low-latency and quality-of-service (QoS).
Airvana's flat-architecture RAN software is available now for integration with communications equipment vendor platforms. The first OEM products based on the flat architecture RAN are expected to begin market trials by early 2008.
