5G Expansion in Limbo Due to FAA Safety Concerns

Experts disagree on whether it’s a concern

Important consequences

  • The FAA has issued guidance that AT&T and Verizon’s 5G services may affect aircraft radio altimeters.
  • The airline industry argues that diversions will result in significant monetary losses in delays and diversions.
  • The telecommunications industry believes that the FAA’s concerns are unfounded.

If the Federal Aviation Administration (FAA) finds its way, starting in January 2022, you will no longer be able to use 5G services from AT&T and Verizon as intended.

The FAA initially argued that 5G C-band antennas could interfere with major airline equipment. She then went ahead and issued several Airworthiness Directives (ADs) ordering airlines to divert flights under certain conditions; it could cost billions of dollars, say industry insiders.

“Had AD applied to Airlines for America members’ 2019 operations on a delayed basis, approximately 345,000 passenger flights, 32 million passengers and 5,400 cargo flights would have been impacted in the form of delayed flights, diversions or cancellations”, concludes Impact. Analysis of FAA 5G Airworthiness Directive for the Americas by airlines, shared with Lifewire.

In November 2021, AT&T and Verizon agreed to delay the commercial launch of 5G C-band wireless service to January 5, 2022, after the FAA raised safety concerns about its potential impact on critical airline equipment. .

As the new rollout date nears, the FAA has released announcements calling for revised flight guidelines to prohibit certain flight operations dependent on the use of radio altimeters in the presence of C-band wireless broadband signals. 5G.

“Despite the lack of credible evidence of an aviation safety risk, US wireless service providers have voluntarily implemented the most comprehensive set of temporary protections in the world.”

In a statement to Lifewire, America’s Airways general manager of industrial communications Carter Yang said the FAA’s ADs had identified safety issues that would be “highly disruptive” to the national airspace system and the audience.

The ADs basically instruct airlines not to rely on radio altimeters when approaching an airport near the C-band 5G antenna and to redirect them to another airport. Airlines for America believes it is the responsibility of telecommunications companies to resolve the impasse.

“Failure to take serious mitigation measures to address 5G carrier interference issues will significantly disrupt and damage the economy at a time when supply chains are already weak,” says Airlines for America Impact Analysis.

false flag

Michael Marcus, an assistant professor of electrical and computer engineering at Northeastern University and an independent expert on wireless technology and spectrum policy, told Lifewire in an email that some radar altimeters are indeed sensitive to 5G in neighboring bands. Still, he was unaffected by the FAA’s response.

“Since [the] “The FAA allowed this issue to surface, but only recently began collecting data on patterns and their frequency.”

As a former vice president of the Federal Communications Commission’s (FCC) Office of Engineering and Technology, Marcus has witnessed similar situations in the past.

Calling adjacent band problems “relatively common”, Marcus pointed to a thirty-year concern between the use of FM broadcasts just below 108 MHz and an aircraft’s Instrument Landing System (ILS) just above above this frequency.

“The real question is whether cellular carriers will be the big burden to resolve this situation, or whether there will be owners of certain models of radar altimeters that do not meet reasonable standards for interference immunity on aircraft “, said Marcus.

Meanwhile, Airlines for America’s Yang said the group continues to encourage the FCC and FAA to work together on a practical solution that will enable the deployment of 5G C-band technology “by prioritizing safety and preventing any disruption of the aeronautical system”.

A similar view was shared by Meredith Attwell Baker, president and CEO of CTIA, a trade association representing the wireless communications industry in the United States and a former member of the FCC. Baker told Lifewire that it’s possible to have both safe flights and robust, reliable 5G service.

“Despite the lack of credible evidence of an aviation security risk, US wireless service providers have voluntarily implemented the most comprehensive set of temporary protections in the world. “We are working closely with the aviation industry and are on track to reach nearly 40 countries in January using 5G securely in C-band.”

Things are unclear at this time, and it’s unclear if 5G C-band services will be available from January 5, 2022, or if the rollout will be further delayed as the two federal agencies jostle for single supremacy.

If the Federal Aviation Administration (FAA) has its way, you won’t be able to use 5G services from AT&T and Verizon from January 2022, as planned. 

Calling for the rollout delay, the FAA first argued that 5G C-band antennas could interfere with crucial airline equipment. It then went ahead and issued a couple of airworthiness directives (AD) ordering airlines to divert flights under certain conditions, which industry insiders say could cost billions of dollars.

“If the AD were applied in arrears to Airlines for America members’ 2019 operations, approximately 345,000 passenger flights, 32 million passengers, and 5,400 cargo flights would have been impacted in the form of delayed flights, diversions, or cancellations,” concludes an Impact Analysis of FAA’s 5G Airworthiness Directive by Airlines for America, shared with Lifewire.

Holding Pattern

In November 2021, AT&T and Verizon agreed to delay the commercial launch of the C-band 5G wireless service until January 5, 2022, after the FAA raised safety concerns about its potential impact on critical airline equipment.

As the new date of the rollout approaches, the FAA issued the ADs calling for the revision of flight manuals to prohibit some flight operations that depend on using radio altimeters when in the presence of 5G C-band wireless broadband signals.

“Despite no credible evidence of a risk to aviation safety, US wireless providers have voluntarily put in place the world’s most comprehensive set of temporary protections.”

In a statement to Lifewire, Carter Yang, Managing Director, Industry Communications for Airlines for America, said the ADs from the FAA identify safety concerns that will be “highly disruptive” to the national airspace system and the public.

The ADs essentially ask airlines not to rely on radio altimeters when approaching an airport near a 5G C-band antenna and instead divert to another airport. Airlines for America believes the onus for resolving the impasse lies with the telecom companies.

“The lack of serious mitigations on the part of 5G telecom companies to address interference issues will significantly disrupt and harm the economy at a time when supply chains are already stretched thin,” reads the Airlines for America Impact Analysis.

False Flag

Michael Marcus, an adjunct professor of electrical and computer engineering at Northeastern University and an independent expert on wireless technology and spectrum policy, told Lifewire in an email that certain radar altimeters are indeed susceptible to 5G in nearby bands. Still, he isn’t impressed by the FAA’s response.

“Since [the] FAA let this problem fester, they only recently started collecting data on which models and how common they are,” he said.

As a former Associate Chief of the Federal Communication Commission (FCC) ‘s Office of Engineering and Technology, Marcus has witnessed situations like these in the past. 

Calling the adjacent band issues “relatively common,” Marcus pointed to a three-decade-old concern between the use of FM broadcasting just below 108 MHz and an airplane’s Instrument Landing System (ILS) just above that frequency.

“The real issue is whether cellular carriers will have the major burden in solving this situation, or the owners of certain models of radar altimeters in aircraft that do not meet reasonable interference immunity standards,” said Marcus.

Middle Ground

Meanwhile, Airlines for America’s Yang said that the group continues to urge the FCC and FAA to work together on a practical solution that will enable the rollout of 5G C-band technology “while prioritizing safety and avoiding any disruption to the aviation system.”

A similar view was shared by Meredith Attwell Baker, President and CEO of CTIA, a trade association representing the wireless communications industry in the US, and a former member of the FCC.

“Despite no credible evidence of a risk to aviation safety, US wireless providers have voluntarily put in place the world’s most comprehensive set of temporary protections. We are working closely with the aviation industry and are on track to join the nearly 40 countries safely using 5G in the C-Band in January,” assured Baker.

Things are in limbo now, and it isn’t clear whether the 5G C-band services will be available starting January 5, 2022, or if the rollout will be delayed further as the two federal bodies jostle for one-upmanship.
