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.

CTA offered its updated take on the FCC’s proposed cybersecurity labeling program for smart devices, in reply comments posted Tuesday in docket 23-239. Most replies were posted Monday (see 2311130034). CTA and other groups said last week the program should be voluntary and based on existing National Institute of Standards and Technology (NIST) guidance (see 2311090033). “The task now falls to the Commission to establish this Program to support efficient procedures for use of the Mark, apply rules consistently and equitably across program participants, and enable the Program to evolve over time,” CTA said. The group called on the FCC to “embrace opportunities to minimize administrative burdens and other participation costs while promoting public trust in the Mark.” The commission “must establish a process for self-attestation, streamline the review and renewal process for devices bearing the Mark, and leverage modern industry practices like e-labeling and other technology solutions,” CTA said. NCTA said most comments agree with its arguments that “the Program’s benefits and ultimate success are more likely to be realized if the technical security criteria for the Cyber Trust Mark are based on existing guidance that NIST has developed through robust engagement with diverse technology and security experts.” Building the program on “NIST’s already-established definition of ‘IoT device’ would maintain a consistent federal approach to IoT security baseline requirements, while also providing a clear vehicle for the Commission to identify and address updates over time,” NCTA said. The Connectivity Standards Alliance noted commenters disagreed on definitions and whether the FCC should certify IoT products or devices. The comments supporting certification of products “for the most part fail to squarely address or recommend a currently available framework for meeting the challenges associated with that approach,” the Alliance said: “The Alliance reiterates its recommendation to launch the Program with an immediately implementable focus on consumer IoT devices, and build from there.”

FCC Commissioner Brendan Carr said during a Federalist Society panel discussion Friday that the Supreme Court’s growing focus on the major questions doctrine and the expected death of the Chevron doctrine (see 2306290063) has potential benefits in forcing lawmakers to make hard policy decisions.

Groups including the Electronic Privacy Information Center (EPIC) and Consumer Reports (CR) supported robust rules as part of the FCC’s proposed cybersecurity labeling program for smart devices in reply comments posted Monday in docket 23-239. In a letter posted last week, CTA, CTIA and other industry groups laid down a marker, saying the program should be voluntary and based on existing National Institute of Standards and Technology (NIST) guidance (see 2311090033).

The Biden administration released its long-awaited national spectrum strategy and a presidential memorandum on modernizing U.S. spectrum policy at a White House ceremony Monday. The plan identifies the 3.1-3.45, 5.03-5.091, 7.125-8.4, 18.1-18.6 and 37.0-37.6 GHz bands for further study by NTIA over the next two years for potential repurposing (see 2311130007). But the plan omits other bands thought to be in the federal cross-hairs. FCC Commissioner Brendan Carr slammed the strategy.

CTIA and NCTA locked horns in reply comments on whether the FCC should examine spectrum aggregation limits. AT&T asked for a rulemaking in 2021, focused on mid-band holdings, but the FCC's questions in a September notice (see 2309220064) go beyond what AT&T sought (see 2310060051). T-Mobile took fire from Dish Network and AT&T.

An FCC NPRM released Thursday proposes allowing schools and libraries to apply for funding from the E-rate program for Wi-Fi hot spots and wireless internet access services that can be used off-premises. FCC Republican Commissioners Brendan Carr and Nathan Simington dissented, as they did last month on a declaratory ruling clarifying that the use of Wi-Fi on school buses is an educational purpose eligible for E-rate funding (see 2310190056).

The Joe Biden administration released its national spectrum strategy Monday and a presidential memorandum on modernizing U.S.policy is coming. Administration officials provided some of the details Monday morning on a call with reporters. The plan identifies 2,786 MHz of spectrum for potential repurposing,

Aeronet told the FCC it can abide by restrictions NTIA proposed in a filing on future use of the 70, 80 and 90 GHz bands. The FCC Wireless Bureau subsequently asked for a record refresh, including comments on the NTIA letter (see 2310180039). “Aeronet is confident that going forward it will be possible to coordinate in less restrictive ways than the NTIA proposed rule text,” said a filing posted Wednesday in docket 20-133: “Aeronet recommends that whatever rules the Commission adopts make clear that direct coordination between service providers in the 70/80 GHz bands and federal users is permitted and even encouraged. As new services are rolled out, direct coordination between users will enhance service delivery, ease overly conservative requirements, and ensure that federal spectrum usage remains protected.” Comments were due Wednesday. AT&T said it generally supports changes to the rules, including modifications to the link registration and antenna standards rules “as those modifications will promote spectrum efficiency and support 5G expansion.” The carrier also supported technical changes “to support 5G services across the nation.” The FCC “should modify its antenna rules to increase the maximum beamwidth from 1.2 degrees to 2.2 degrees, reduce minimum antenna gain from 43 dBi to 38 dBi, and reduce co-polar and cross-polar discrimination requirements for 70/80 GHz antennas,” AT&T said: “These rule changes would enable the development of smaller, lighter antennas that are more adaptable for 5G backhaul deployments in diverse settings.” Tech company Sierra Nevada asked that any use of the spectrum doesn't “undermine” proposals separately made to the FCC to allocate the 90 GHz band to enhanced flight vision system radar (see 2203250061). “Allowing that use could greatly enhance aviation safety by enabling pilots to have an additional visual-like reference to surrounding terrain, obstacles, buildings, and the airport environment,” the company said. The National Radio Astronomy Observatory (NRAO) asked the FCC to examine adjacent-band protections for radioastronomy operations at 76-81 GHz. “Radio astronomy is not allocated in the spectrum band at 71-76 GHz so the use case of radio astronomy operations immediately above 76 GHz must be discussed separately, and this is missing,” NRAO said.

AI, quantum science and other emerging technologies can make telecom networks more secure, but they also create new challenges when used by bad actors, Rich Baich, AT&T chief information security officer, said during an AT&T forum Wednesday. Former Cybersecurity and Infrastructure Security Agency Director Christopher Krebs said the government will always be limited in the role in can play in making networks more secure. The forum comes as the FCC considers a notice of inquiry on using AI to curb unwanted robocalls (see 2310250070).
