DOCOMO commits to multivendor O-RAN for 4G/5G

NTT DOCOMO has commenced deployment of a 4G/5G multivendor radio access network conforming to O-RAN specifications.

Working in collaboration with Fujitsu, NEC, and Nokia, DOCOMO has demonstrated multi-vendor interoperability across a variety of 4G and 5G base station equipment compatible with O-RAN. The O-RAN standards include fronthaul specifications and X2 profile specifications.



O-RAN fronthaul specifications are used to establish the connections between centralized units hosting baseband processing and remote units hosting radio processing in 5G remote-installed base stations. O-RAN fronthaul interface specifications provide a foundation for interoperability between centralized units and remote units of 5G remote-installed base stations manufactured by diverse partners.

The O-RAN X2 profile specifications provide a foundation for interoperability between 4G base stations and 5G base stations manufactured by diverse partners in 5G non-standalone (5G NSA) networks by taking 3GPP X2 interface specifications and specifying detailed standards for their usage. 5G NSA networks connect devices using both 4G and 5G technologies.

DOCOMO believes this represents the world's first realization of this level of multi-vendor interoperability in 4G and 5G base station equipment conforming to O-RAN specifications. The ability to deploy and interconnect base station equipment from different vendors will make it possible to select the equipment most suitable for deployment in any given environment, such as base stations offering broad coverage in rural areas or small base stations that can be deployed in urban areas where space is limited.

DOCOMO will deploy the equipment in the pre-commercial 5G service it plans to launch on September 20, 2019 in Japan.

Reliance Jio, TIM, and Verizon join O-RAN board

The O-RAN Alliance, which is a carrier-led effort to open the radio access network of next generation wireless systems, released its inaugural white paper, “O-RAN: Towards an Open and Smart RAN,” which is available on the O-RAN website. The white paper describes the O-RAN architecture, which drives a more cost-effective, intelligent RAN with open interoperable interfaces for next generation 5G networks and beyond.

The O-RAN Alliance also announced that Reliance Jio, TIM, and Verizon have joined the O-RAN board.

“It’s encouraging to see the O-RAN Alliance off to such a strong start and gaining momentum as we welcome three new board members. It’s important that the wireless industry continues to come together to drive forward O-RAN’s goals for open networking, software, and virtualization in global wireless networks especially as 5G is closer than ever,” said Andre Fuetsch, Chairman of the O-RAN Alliance, President-AT&T Labs and CTO of AT&T.

“We are pleased with the smooth transition of both C-RAN Alliance and xRAN Forum contributors into the O-RAN Alliance work groups,” said Dr. Sachin Katti, Professor at Stanford University and O-RAN Alliance TSC Co-Chair. “We’ve seen advancement on all fronts. The mix of new contributors and ideas promises to accelerate our progress during this next phase of O-RAN Alliance specifications and reference designs.”
