Rakuten Symphony talks Open RAN benefits and bringing radio disaggregation to brownfield network environments Beginning in 2018, Rakuten Mobile, a subsidiary of Japanese conglomerate Rakuten Group, started deploying a greenfield Open RAN network. Since then, Rakuten Group has also spun off hardware/software and consultancy vendor Rakuten Symphony to sell its technology stack and approach to operationalizing an Open RAN network. In the recent Open RAN Global Forum, available on demand, Rakuten Symphony Chief Business Officer Rabih Dabboussi reflected on the why and how of the approach in Japan, and what he sees driving adoption of Open RAN in the larger brownfield network market.
In terms of why Rakuten Mobile elected to go with Open RAN, Dabboussi highlighted three main drivers. First, he said because Rakuten Mobile was entering a market with three established incumbent operators, they need a more advantageous cost structure focused on TCO reduction to gain a competitive edge. Second, given Rakuten Group’s large reach into things like e-commerce, financial services, travel, entertainment and more, mobile fit into a larger data-driven platform strategy. And third, “We don’t believe in a building a huge organization to keep the lights up…The adoption of a software-centric, highly programmable network leveraging highly optimized cost compute and storage and network systems.”
“We strongly believe in this mission,” he said. “We strongly believe in our technology stack, and as we built it and used it ourselves, we created yet a new company called Rakuten Symphony that would take the technology, the solutions, the products, and the overall architecture and provide it to other telcos around the world, both brownfield and greenfield.”
Asked why, given the performance, cost and other upsides associated with Open RAN, adoption has been slower than many would like, Dabboussi gave a clear-eyed response. “Because it takes time, he said. “And because it takes time, I think the industry has been super critical of itself…And this is my call to the whole industry that the future is heading that way. It is slow, yes, the technology is nascent, yes, but it’s going to get there.”
