Not clear whether all 5G providers will defer.

Need to hold a POST MORTEM to learn how to avoid this Game of Chicken– how did two technologically sophisticated federal agencies refuse to budge UNTIL a potentially disastrous event reached a near time horizon!!!


AT&T and Verizon agree to pause 5G rollout over FAA safety concerns

The FAA warned earlier this week of potential interference issues between aircraft safety devices and 5G service using new C-band spectrum.

AT&T and Verizon confirmed Thursday that they’ve agreed to temporarily pause rolling out 5G service that uses a new set of radio frequencies. The carriers will work with the US Federal Aviation Administration to address concerns about potential interference between key cockpit safety devices and towers on the ground transmitting 5G signals.

AT&T said in a statement that it planned to delay its 5G deployment until Jan. 5 after getting a request from the Transportation Department, which oversees the FAA.

A Verizon spokesman confirmed to CNET that the company has also agreed to a temporary pause in deployment of 5G over the C-band spectrum in order to work in good faith with the agency. But he said the company is still on track to deploy service using this midband spectrum.

“We’re moving full speed ahead with our plans to bring 5G over this spectrum in early 2022,” the Verizon spokesman said.

Verizon had previously said it planned to deploy service using the C-band spectrum in the first quarter of 2022, to cover 100 million people.

News of the voluntary pause in deployment by AT&T and Verizon was reported earlier by The Wall Street Journal.

The FAA and the Federal Communications Commission, which regulates use of public wireless spectrum for communication, issued a joint statement saying they’d work with the companies to mitigate safety concerns and to continue to coordinate efforts to ensure safety.

The FAA on Tuesday issued a special information bulletin alerting manufacturers, operators and pilots about potential interference involving cockpit electronics and 5G. The FAA has said towers on the ground transmitting 5G over the C-band of wireless spectrum could interfere with automated cockpit systems such as those that help planes land in poor weather.

The agency had been planning to issue official mandates to limit the use of certain cockpit systems, according to a report by The Wall Street Journal.

Telecom industry specialists say there’s no evidence of interference issues with respect to the C-band spectrum and flight equipment. CTIA, the wireless industry lobby group, said in a filing to the FCC on Wednesday that “nearly 40 countries have already adopted rules and deployed hundreds of thousands of 5G base stations in the C-Band at similar frequencies and similar power levels — and in some instances, at closer proximity to aviation operations — than 5G will be in the U.S.”

CTIA went on to say that none of the countries using this spectrum for 5G has reported any harmful interference with aviation equipment from these deployments. The group urged the FCC to “ensure that C-Band 5G deployments remain on track in the U.S.”

New spectrum for 5G

The spectrum or airwaves used to transmit the 5G service in question is known as C-band. This midband spectrum in the 3.7-3.98GHz band has been viewed by the wireless industry as a key technology to allow for faster 5G service that can provide better range than 5G service using very high frequency millimeter-wave spectrum.

Verizon says that this new spectrum will allow it to offer peak download speeds of 1 gigabit per second.

The FCC auction of the C-band airwaves earlier this year generated a record-breaking $81 billion in proceeds. Verizon and AT&T were the two biggest winners. Verizon won $45.45 billion worth of licenses, while AT&T spent $23.4 billion on its C-band airwaves.

In March, Verizon said it would start deploying this midband spectrum for 5G service in 46 markets with the goal of covering 100 million people by next March. That number will grow to 175 million people between 2022 and 2023 and over 250 million people in 2024, the company said.

For AT&T and Verizon the addition of the C-band spectrum for 5G is a key part of their wireless strategies. Though millimeter spectrum, which both carriers currently use for their fastest 5G service, provides speedy downloads, it’s generally available only outdoors in parts of certain cities because of physical limitations of the spectrum.

By contrast, the nationwide 5G service offered by these carriers uses a combination of 4G and 5G technologies over lower frequency spectrum. The benefit of this spectrum is that it can transmit signals over longer distances, but the speeds that can be obtained are similar or sometimes even less than what can be achieved over existing 4G LTE service.

The promise of the C-band midband spectrum is that it can offer faster speeds over greater distances, which should help these companies improve 5G service in urban and suburban markets. And because midband spectrum is able to penetrate walls more easily than millimeter wave technology, it should also improve 5G coverage indoors.

FCC 5G and Commerce v. FAA GPS and Safety

Aviation Members and DOD agree with FAA

Game of Chicken Day–12.5.2021

 

 

Unless some resolution is agreed to, on December 5, 2021, the US will be subject to a high level, policy GAME OF CHICKEN between the FAA and the FCC which might result in the bottom right corner safety disaster outcome.

This debate  has been festering for years:5G battle behind the scenes

Two Attacks On GPS Navigation Integrity Could Cause An Aviation Disaster  MARCH 10, 2021

Key Members of the House of both parties (Chairs DeFazio, Larsen Express Continued Concern over FCC Approval of Ligado License Application After Briefing with Agency Officials; Graves: Interference Of The GPS Signal Will Cost American Small Businesses Billions & Compromise Safety) have sided with the Safety Concerns. U.S. Senators Jim Inhofe (R-Okla.), ranking member of the Senate Armed Services Committee, Tammy Duckworth (D-Ill.), and Mike Rounds (R-S.D.) introduced the RETAIN GPS and Satellite Communications Act on June 23, 2021. If the bill passes, it will force communications company Ligado to pay the costs associated with any GPS interference from their terrestrial-based 5G telecommunications — both in the private and public sector. If one can dispose of those strong positions as being subject to aviation bias, the original creator of GPS agrees from a NATIONAL DEFENSE perspective (US military is furious at FCC over 5G plan that could interfere with GPS)..

As noted below, an airline and aviation industry group presented a lengthy, detailed presentation to the FAA. Among the convincing information on 5G’s impact on aviation was this chart showing how this powerful signal could alter the navigation of an EMS helicopter–

A year old analysis by the highly respected RTCA found that this much craved commercial addition will negatively impact all sectors of aerial navigation:

Not to disparage the importance of commerce and communications, but it would seem appropriate here to prioritize safety over a short term addition to the already robust communication panoply. A delay to implement reasonable precautions would occupy the bottom left hand corner of the above Game of Chicken instead of the bottom right hand option which will increase the risk of a dire consequence, such as—

NOTE: the FAA is taking steps designed to mitigate the 5G risk, but at the expense of aviation capacity—a primary highway of our country’s and the world’s economy!!!

FAA has ‘deep concern’ about 5G network plan on aviation safety — letter

By David Shepardson5G and GPS interference

WASHINGTON, Oct 29 (Reuters) – The Federal Aviation Administration (FAA) has raised significant concerns about a plan to use spectrum for 5G wireless networks on aviation safety and is planning to issue a formal warning about the issue, according to sources and a letter seen by Reuters.

The aviation industry has voiced alarm about the plan to use C-Band spectrum for more than a year. Network carriers are expected to begin using the spectrum starting Dec. 5 starting in 46 markets.

FAA Deputy Administrator Bradley Mims in a previously unreported Oct. 6 letter said the agency shares “the deep concern about the potential impact to aviation safety resulting from interference to radar altimeter performance from 5GDeputy Administrator Mims network operations in the C band.”

An FAA spokeswoman said Friday it “continues to engage with other agencies so that aviation and the newest generation of 5G cellular technology can safely coexist.”eport ad

The Federal Communications Commission said Friday it remains committed to ensuring air safety as the agency’s successful track record demonstrates, while moving forward with the deployment of new technologies that support American business and consumer needs.”

The FAA held a lengthy Oct. 14 meeting with the aviation industry on the issue. FAA and FCC officials have held numerous discussions about the issue, the sources said.

The FAA is planning to soon issue a Special Airworthiness Information Bulletin and an airworthiness directive about the issue, two officials told Reuters, confirming a Wall Street Journal report.

The aerospace and airline sector met with the FCC in August, warning without changes “major disruptions to use of the National Airspace System can be expected from the rollout of 5G” and added the FAA will be forced to “drastically reduce aviation operational capacity.” .

Wireless trade group CTIA said Friday 5G networks can safely use C-band spectrum “without causing harmful interference to aviation equipment,” and cited numerous active 5G networks using this spectrum band in 40 countries… Any delay in activating this spectrum risks America’s competitiveness.”CTIA 5G pitch

One longer-term solution is retrofitting some altimeters with “out-of-band filters,” but it would likely take years and “many thousands of civil aircraft are likely to be impacted, the aviation industry said.
