Airvana’s Flat-Architecture Base Station combines base station and radio network controller (RNC) software with the functionality of a packet data serving node (PDSN). This flat architecture combines all functions of the radio access network into a single node, making the deployment of the networks simpler and more economical. The flat architecture reduces the number of network elements required to build an EV-DO network, making the network more reliable, more flexible, easier to engineer and deploy, and less costly to operate. The Flat Architecture Base Station can be connected directly to the Internet and is intended for use in macro EV-DO network deployments. The network deployments include enterprise, campus, hot spot, and public safety deployments where the small footprint, reliable network architecture, and low cost of deployment and maintenance are critical.
Traditional hierarchical mobile broadband radio access networks serve user traffic in multiple types of nodes. For example, in EV-DO networks, the base station, RNC, PDSN and mobile IP home agent all cooperate to serve user traffic. Combining these functions into a single node reduces latency, decreases captial and maintenance cost of the network, and reduces the complexity of interactions between the nodes to deliver end-to-end Quality of Service (QoS).
