Thanks to its operational cost advantage, Rakuten Mobile is able to provide its customers with very attractive tariffs. “I think this is going to be widely adopted inside of Japan,” Davidson predicts. “This is just the beginning. Now we need to get to 5G and we need to scale the infrastructure.” As it deploys 5G, Rakuten Mobile could further extend its cost advantage over legacy networks.
As well as supplying the IP (internet protocol) routers that transport traffic from Rakuten’s minimalist radio towers and the cloud radio access network (RAN) into the IP core, Cisco is also providing the management orchestration software for the virtual cloud native functions and software required to support third party applications. “Cisco is playing a crucial role in stitching together the various elements of our new network,” says Rakuten Mobile CTO Tareq Amin. “The design approach we mapped out with Cisco is enabling us to deliver high-value services at very affordable prices, enabling our customers to really benefit from our cloud innovation. Scaling of such orchestration function is a challenge.”
As Rakuten Mobile’s software-defined architecture enables it to fine-tune its network in real-time, Davidson expects the network to perform at a very high level, bringing reliability and throughput benefits to customers. As the performance, technical and operations advantages become increasingly apparent, Cisco expects other operators to follow in Rakuten Mobile’s footsteps and deploy cloud-based radio access networks underpinned by open specifications, rather than vendors’ proprietary hardware and software.
