How 5G Could Make a Mess of a Flight

If certain not-yet-activated 5G phone frequencies don’t stay in airplane mode, the Unites States Federal Aviation Administration (FAA) is prepared to hang up on some flights in January.

How 5G Could Make a Mess of a Flight

This was contained in a article carried by written by Rob Pegoraro in USA TODAY.

According to the article, the regulatory agency (FAA)announced early in December  that possible interference with aircraft radio altimeters from upcoming C-Band cell-site transmitters would require it to prohibit pilots from relying on those instruments to track their altitude above the ground near particular airports.

Or in plainer language than that of this FAA Airworthiness Directive: If bad weather means pilots can’t see a runway near those cell sites after AT&T and Verizon light up C-Band frequencies January 5, expect them to land elsewhere. Or not take off at all.

“You’ll be forced to divert the flight to an airport that is not 5G-covered,” said Robert Mann, president of the aviation-industry consulting firm R.W. Mann. & Co. “Or you’ll have to not dispatch the plane.”

But while we won’t know which flights might get an FAA veto until the agency issues NOTAMs (“Notice to Air Missions”) naming airports, the weather allows forecasts. John Cox, a retired US Airways pilot who writes USA TODAY’s Ask the Captain column, said the D.C.-to-Boston megalopolis and the Pacific Northwest were especially at risk of cascading interruptions.

“The whole Northeast Corridor can be down when you have the right fog conditions,” he said. “The other one that concerns me is the Northwest: Seattle, Portland, those areas where the fog is a matter of routine.”

The actual risk of interference remains unclear. As the FAA directive notes, the 3.7-3.98 GHz frequencies for which AT&T and Verizon paid $23 and $45 billion early this year don’t overlap radio altimeters’ 4.2-4.4 GHz frequencies. Some models of altimeter might get confused anyway by adjacent signals–but we still don’t know which ones.

“There’s no excuse for the FAA’s delay in its survey of existing altimeter models,” complained Harold Feld, senior vice president at the tech-policy nonprofit Public Knowledge, who wrote last month that this research should have started a year ago.

AT&T and Verizon already pushed back their C-Band launches – which will fill a gap in their 5G networks compared to T-Mobile, which already offers fast “midband” 5G on 2.5 GHz frequencies – and in November agreed to reduce C-Band signals’ power for six months.

The wireless-industry trade group CTIA also points to successful C-Band 5G deployments in dozens of other countries, but the FAA directive notes that regulators elsewhere require “temporary technical, regulatory, and operational mitigations.”

The Air Line Pilots Association supports the agency; union spokesperson Corey Kuhn emailed a list of those mitigations, most featuring much tighter restrictions on C-Band power. For example, in November Canada announced limits on C-Band power around airports and a ban on C-Band cell sites closer to runways; implementing those rules here would leave many AT&T and Verizon subscribers with lesser 5G service.

Cox defended the FAA’s caution: “Just to categorically say, ‘Oh, it’ll be okay, we think,’ that is not consistent with the way we’ve conducted aviation safety.”

The FAA directive does invite airlines to certify that they’ve tested their equipment against C-Band interference, although Mann noted that replacing susceptible altimeters would demand extra testing and certification: “It’s more than just plugging in a new radio altimeter.”

Feld, however, said airline self-certification represents the most likely solution because airlines will take the heat for flight interruptions.

“If people’s flights are delayed, they’re not going to blame Verizon and AT&T,” he said. “They’re going to blame Southwest Airlines and Delta.”

Nigerian Communications Commission (NCC) has thrown its weight behind the upcoming Telecom Sector Sustainability Forum (TSSF 7.0), confirming its role as the headline keynote speaker for the Lagos event.

NCC to Keynote Telecom Sector Sustainability Forum 7.0

Over the years, the Telecoms Sector Sustainability Forum (TSSF) has evolved into a landmark industry convergence platform and an actionable catalyst for policy alignment, driving critical dialogue around the regulatory, economic, and infrastructural frameworks required to sustain Nigeria’s digital economy.

Taking place on 16th September, 2026, at the Radisson Blu Hotel, Ikeja, Lagos State, the seventh edition of the Telecoms Sector Sustainability Forum (TSSF 7.0), organised under the aegis of Business Remarks, will bring together key stakeholders driving the next phase of Nigeria’s telecommunications and digital growth.

Themed “Rethinking Nigeria’s Digital Infrastructure Strategy to Attract Investment and Drive Innovation”, TSSF 7.0 will address some of the sector’s most pressing priorities, such as policies, digital infrastructure expansion, digital inclusion, good connectivity, partnerships and investments needed to accelerate Nigeria’s next wave of innovations, digital transformation and economic growth.

Organised by Business Remarks, the forum has consistently brought together policymakers, mobile network operators (MNOs), infrastructure providers, data centre operators, policy advocates and financial technology stakeholders to dissect the pressing challenges facing the telecommunications ecosystem and chart a sustainable path forward.

Past editions have successfully addressed pivotal industry shifts, ranging from broadband penetration strategies, human capital flight, mobile virtual network operators (MVNOs) sustainability and infrastructure deficit funding to the operational integration of emerging technologies. By providing a neutral, high-level platform where regulators like the Nigerian Communications Commission (NCC) can interface directly with private sector players, the forum plays a vital role in ensuring that regulatory frameworks evolve in tandem with market realities.

Speaking about the event, the Convener, Bukola Olanrewaju, said the Nigerian telecoms sector investment has grown to $75.6 billion as of 2025, with a planned investment of over $1.38 billion in network capacity upgrades in 2026 targeted to enhance infrastructure resilience, boost coverage and improve quality of service for subscribers nationwide.

“As the industry faces a new frontier defined by deepening 5G and 4G penetration, expanding fibre optic networks, and complex macroeconomic pressures, the need to meet the growing demands for digital services while remaining profitable has become the defining challenge of the modern telecommunications landscape.”

At a time when investment in connectivity, subsea cables, fibre networks, data centres, cloud infrastructure and cybersecurity is reshaping the country’s digital landscape, TSSF remains a vanguard of thought leadership and industry engagement, fostering the public-private collaborations necessary to safeguard the backbone of Nigeria’s digital transformation.

Nigerian Communications Commission (NCC) has reaffirmed its commitment to promoting efficient broadband infrastructure deployment in Nigeria through collaborative implementation of the Dig Once Policy.

L-R: Prof. Olalekan Yinusa, Executive Director, Policy, Strategy and Research, Nigeria Governors’ Forum; Mr. Ayuba Shuaibu, Director, Policy Competition and Economic Analysis, Nigerian Communications Commission, NCC; Engr. Nadungu Gagare, Permanent Secretary, Federal Ministry of Communications, Innovation and Digital Economy; Dr. Helen Aderibigbe Adeniyi, Hon. Commissioner, Ministry of Innovation Science and Technology, Kogi State, during the 2nd Stakeholders ‘ Consultative Forum on the Study to Develop a Mechanism and Cost-Based Structure for Sharing Duct Built Under The Dig-Once Policy in Nigeria, on the 8th July 2026, at the NCC Annex Office Mbora Abuja.

The Commission gave the assurance at the Second Stakeholders’ Consultative Forum to Develop a Pricing Mechanism and Cost-Based Structure for Sharing Ducts Built Under the Dig Once Policy in Nigeria, held at the NCC Annex Office, Mbora, Abuja, on Wednesday.

The forum brought together representatives of federal and state government institutions, telecommunications operators, infrastructure companies, industry associations, development partners and other key stakeholders to deliberate on the interim findings of the study and provide input towards the development of a transparent, equitable and cost-based framework for sharing underground duct infrastructure.

Speaking at the event, NCC’s Director, Policy, Competition and Economic Analysis, Mr Ayuba Shuaibu, said the consultative engagement underscored the Commission’s commitment to an open, transparent and inclusive regulatory process that accommodates the interests of infrastructure providers, network operators, public institutions and consumers.

Shuaibu noted that the proposed framework is intended to encourage infrastructure sharing, improve asset utilisation, reduce the cost of broadband deployment and facilitate the expansion of telecommunications infrastructure across the country.

According to him, the study is designed to establish a fair and transparent pricing mechanism for sharing underground ducts deployed under Nigeria’s Dig Once Policy, which encourages the installation of telecommunications ducts during road construction and rehabilitation projects. He explained that this would enable future fibre deployments without repeated road excavations.

“The Commission remains committed to a transparent, inclusive and consultative process. Our objective is to arrive at a pricing structure that balances the interests of infrastructure providers, access seekers and, ultimately, consumers, while also encouraging continued investment in broadband infrastructure.

“We encourage frank, constructive and solution-oriented contributions that will strengthen the final outcomes of this study,” Shuaibu said.
He added that observations, recommendations and contributions received from stakeholders during the consultation would be reviewed and incorporated into the final study report to ensure that the resulting framework is practical, commercially sustainable and responsive to industry realities.

Delivering the keynote presentation, the consultant, Mr Olugbenga Olabiyi, Managing Director of Dimension Data Limited, observed that passive infrastructure, including ducts, conduits, manholes and related facilities, constitutes one of the most capital-intensive components of broadband network deployment globally.

He said infrastructure sharing had emerged as an effective strategy for reducing deployment costs, improving efficiency and accelerating broadband expansion.
Olabiyi stated that Nigeria’s adoption of the Dig Once Policy presents an important opportunity to strengthen coordinated infrastructure deployment, minimise avoidable road excavations, improve utilisation of existing infrastructure and support broader broadband access across the country.

He also emphasised the importance of developing a predictable, transparent and equitable access framework, noting that inconsistent pricing models and unclear access conditions could undermine investment incentives and limit the benefits of infrastructure sharing.

“For Nigeria, where broadband expansion remains a national priority under the National Broadband Plan, successful implementation of the Dig Once Policy could become one of the most impactful infrastructure reforms in our telecommunications history.

“However, infrastructure sharing succeeds only when access is governed by fairness, transparency, predictability and effective market oversight.
“Without an equitable access framework, owners of shared infrastructure may inadvertently or deliberately create barriers to entry through excessive pricing, restrictive commercial conditions or discriminatory access practices. Such outcomes would undermine the objectives of the Dig Once initiative and discourage investment rather than promote it.

“This is why the NCC’s initiative to develop a cost-based pricing framework deserves commendation. A transparent and objective pricing methodology will provide confidence to investors, infrastructure companies, mobile network operators, Internet Service Providers, fibre operators and all participants within the communications ecosystem,” he said.

Participants at the forum reviewed the interim findings and provided recommendations on the proposed pricing methodology, implementation considerations and cost elements. Discussions focused on ensuring that the policy supports efficient infrastructure deployment while balancing the interests of infrastructure providers, access seekers and consumers.

The stakeholder consultation builds on earlier engagements conducted by the Commission on the study. It also aligns with the NCC’s commitment to implementing regulatory initiatives that promote broadband expansion, encourage infrastructure sharing and advance Nigeria’s digital transformation agenda.
