WASHINGTON, February 2, 2023 – A global approach to funding open radio access networks will improve its success in the United States, say commenters to the National Telecommunications and Information Administration.
The NTIA is seeking comment on how to implement the $1.5 billion appropriated to the Public Wireless Supply Chain Innovation Fund as directed by the CHIPS and Science Act of 2022. The grant program is primarily responsible for supporting the promotion and deployment of open, interoperable, and standards-based radio access networks.
Radio access networks provide critical technology to connect users to the mobile network over radio waves. O-RAN would create a more open ecosystem of network equipment that would otherwise be reliant on proprietary technology from a handful of companies.
Global RAN
Commenters to the NTIA argue that in order for O-RAN to be successful, it must be global. The Administration must take a “global approach” when funding projects by awarding money to those companies that are non-U.S.-based, said mobile provider Verizon in its comments.
To date, new entrants into the RAN market have been the center for O-RAN development, claimed wireless service provider, US Cellular. The company encouraged the NTIA to “invest in proven RAN vendors from allied nations, rather than focusing its efforts on new entrants and smaller players that lack operational expertise and experience.”
Korean-based Samsung Electrontics added that by allowing trusted entities with a significant U.S. presence to compete for project funding and partner on those projects, the NTIA will support standardizing interoperability “evolution by advancing a diverse global market of trusted suppliers in the U.S.”
O-RAN must be globally standardized and globally interoperable, Verizon said. Funding from the Public Wireless Innovation Fund will help the RAN ecosystem mature as it desperately needs, it added.
Research and development
O-RAN continues to lack the maturity that is needed for commercial deployment, agreed US Cellular in its comments. The company indicated that the complexity and costliness of system integration results from there being multiple vendors that would need to integrate but are not ready for full integration.
Additionally, interoperability with existing RAN infrastructure requires bi-lateral agreements, customized integration, and significant testing prior to deployment, the comment read. The complicated process would result in O-RAN increasing the cost of vendor and infrastructure deployment, claimed US Cellular, directly contrary to the goals of O-RAN.
Several commenters urged the NTIA to focus funding projects on research and development rather than subsidizing commercial deployments.
The NTIA is already fully engaged in broadband deployment in unserved and underserved areas through its Broadband Equity, Access and Deployment program, said Verizon. The Innovation Fund will better advance its goals by funding projects that accelerate the solving of remaining O-RAN technical challenges that continue to delay its deployment, it continued.
US Cellular argued that the NTIA should “spur deployment of additional independent testing and certification lab facilities… where an independent third party can perform end to end testing, conformance, and certification.”
The Innovation Fund should be used to focus on technology development and solving practical challenges, added wireless trade association, CTIA. Research can focus on interoperability, promotion of equipment that meets O-RAN specifications, and projects that support hardware design and energy efficiency, it said.
Furthermore, CTIA recommended that the Administration avoid interfering in how providers design their networks to encourage providers to adopt O-RAN in an appropriate manner for their company. Allowing a flexible, risk-based approach to O-RAN deployments will “help ensure network security and stability,” it wrote.
