While Work Remains, ORAN Is Starting to Hit Its Stride

Despite a slow start, open radio access networks are starting to build momentum, including in the U.S., speakers said Tuesday during an Informa Tech webinar. Getting the timing right will be difficult but “the commitment is there from large operators” to move to open networks, said Gabriel Brown, senior principal analyst-mobile networks & 5G at Heavy Reading. Vodafone, Deutsche Telekom and other big European operators are committed to ORAN, he said. In the U.S., ORAN has gone “a little slower than some anticipated” but U.S. carriers are “pioneering” virtual RAN and cloud RAN, he said. Brown also noted Dish Network’s deployment of ORAN technology in its network build. “We’re starting to see it pick up in other regions,” he said. Japan’s Docomo is probably the biggest incumbent so far, he said. Vodafone had its first ORAN deployment in 2019 in the U.K., said Lucia De Miguel Albertos, senior ORAN manager. ORAN requires “continuous work,” she said. “It takes months of efforts, even years … to have a good performance,” she said. Vodafone decided as part of its ORAN program that it had to serve as its own system integrator, Albertos said. In the U.K., Vodafone started its deployment using Samsung as system integrator but plans to take on those responsibilities if all goes as planned, she said. ORAN “is no longer a concept. We have seen it being deployed commercially by many” major carriers “across the globe,” said Prakash Desai, senior director-product management at ORAN company Wind River. The network performance metrics operators are seeing are “at par or better, in some cases, than traditional networks,” he said. Work remains on ORAN standardization, including on the RAN intelligent controller, data operation, automation and accelerating apps, he said. “Interoperability is always complex,” he said. “What is needed now is scale -- more and more tier-one [operators] to jump on the bandwagon and say, ‘Yes, we can do it,’” Desai said. Wind River has worked with Verizon to deploy more than 30,000 virtual nodes carrying network traffic, he said. Verizon’s 5G network covers the New York metro area “and there cannot be a more dense urban network than New York City,” he said: Virtualized nodes have been deployed there and working for more than two years.
