As an industry first, this vRAN software takes the open virtualized RAN concept, pioneered by Altiostar, and further decomposes the network functions into containerized applications that are fast to deploy, can be individually upgraded and offer better network scalability. The software dramatically improves the economics, deployability and scalability of 5G RANs for mobile network operators (MNOs).
In October 2019, Rakuten Mobile launched its fully virtualized mobile network using Altiostar's cloud-based RAN with an open ecosystem of vendors. With this new technology, Rakuten Mobile intends to launch its 5G network with a top-down focus on services and applications and leverage the cloud infrastructure it has built for 4G.
"Altiostar as the first company to virtualize the RAN, including the lower layers of the protocol stack, is again leading the industry with the development of cloud-native containerized radio access technology," said Ashraf Dahod, CEO of Altiostar Networks. "This new architecture will allow service providers to develop 5G services that are even more responsive to consumer needs over their entire network deployment lifecycle."
"We pushed the envelope in terms of how mobile networks are deployed and had several industry firsts when we introduced the fully cloud-based, software-defined Rakuten Mobile network," said Tareq Amin, Chief Technology Officer (CTO) at Rakuten Mobile.
"With our 5G launch, we want our users to be able to also experience the next generation of applications and services. A cloud-native microservice-based architecture will allow us to focus on identifying these 5G applications and services with the knowledge that the end-to-end network, including the RAN functions, has the modularity, flexibility and the agility to roll them out."
