US Government Requests Two-Week Delay for 5G Deployment, Citing Aviation Safety (reuters.com) 36

Reuters reports: U.S. Transportation Secretary Pete Buttigieg and the head of the Federal Aviation Administration (FAA) on Friday asked AT&T and Verizon Communications to delay the planned January 5 introduction of new 5G wireless service over aviation safety concerns. In a letter Friday seen by Reuters, Buttigieg and FAA Administrator Steve Dickson asked AT&T Chief Executive John Stankey and Verizon Chief Executive Hans Vestberg for a delay of no more than two weeks as part of a "proposal as a near-term solution for advancing the co-existence of 5G deployment in the C-Band and safe flight operations."

The aviation industry and FAA have raised concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters that could disrupt flights.... Earlier Friday the two companies accused the aerospace industry of seeking to hold C-Band spectrum deployment "hostage until the wireless industry agrees to cover the costs of upgrading any obsolete altimeters." Buttigieg and Dickson said under the framework "commercial C-band service would begin as planned in January with certain exceptions around priority airports...." The carriers, which won the spectrum in an $80 billion government auction, previously agreed to precautionary measures for six months to limit interference...

Wireless industry group CTIA said 5G is safe and spectrum is being used in about 40 other countries.

US Government Requests Two-Week Delay for 5G Deployment, Citing Aviation Safety

  • I know why this is probably an issue in the US, but why does it appear to be an issue *only* in the US?

    FTA: "Wireless industry group CTIA said 5G is safe and spectrum is being used in about 40 other countries."

    And everyone in aviation design I talk to seems to basically say the same: The design of the radar altimeter is shit, but there are no technical issues.

      Observer bias.

      France's aviation regulator has blocked the installation of 5G near airports and issued warnings to pilots.
      Australia's ACMA has run simulations and is actively watching the situation since they identified interference can occur as well despite the guardband being 3x larger than the USA's.

      I really don't understand why this is an issue now either. They have literally had **years** to test this and just now they're freaking out? It doesn't make any sense.
  • What are a few more weeks where that is certainly nowhere near enough time to make the needed Aviation adjustments

      Does it occur to anyone that this concern just now coming up is a bit late in the game of 5G?

      Like who is responsible for not thinking about this years ago?

      • by splutty ( 43475 )

        No one is responsible for that, because it was thought about years ago. And determined it wasn't an issue.

        This is just getting cold feet, it seems, after all the aviation fuckups in the US.

        That's.. All I can think of.

        • And determined it wasn't an issue.

          And yet all simulations based on the same assumptions from a few years ago show it is an issue.

          . . . it was thought about years ago. And determined it wasn't an issue.

          Determined by the cell-phone industry to be not an issue, not determined by the airlines to be not an issue. To make it not a potential issue, the airlines would have to update some of their equipment.

    • "2 more weeks," that's not the same as "a few more weeks" - that's "we'll postpone it again in 2 weeks."

        Based on recent headlines, I thought the flights were already all delayed that much.

    With over 40 countries safely deploying the new C-band 5G, it doesn't appear to have any safely issues unless an airline has out of specification equipment that bleed outside their designated bandwidth. A quote from the article demonstrates idiocy: "House Transportation Committee chair Peter DeFazio Friday backed the airline group petition warning "we can’t afford to experiment with aviation safety." Any yet Boeing was allowed to release airplanes with "optional" safely features that lead to the crash of two planes and many dead. These politicians are dishonest frauds.
    • What countries? Countries like Australia where the ACMA is actively monitoring the situation after their own simulations determined the level of interference breaches ITU regulations? Countries like France which has limited 5G deployments near airports for the same issue?

    • These politicians are dishonest frauds.

      Have you any evidence that other politicians are not?

      Could you please point to the specifications that you think the aircraft violate?

    Verison and ATT bought the ones that are close to the aviation bands. Other vendors do not have this problem.

    To help you understand the issue that Verison and ATT have, is they bought the bands that are faster, but shorter distance.
    So they would be better in high density metropolitan areas. The problem is those same areas have lots of airports.
    • Other vendors do not have this problem.

      Australia disagrees, and their 5G deployments are 500MHz lower than the USA's

      • Thats a different band.
      • Jesus how many times are you going to repeat yourself?

        This is a story on the USA bandwidth no one cares about what Australia is doing or what France is thinking about doing.
        It's not even the same spectrum your harping on a apples to oranges issue.

          I will continue to repeat myself every time some moron says "why is it only USA?" or "why is it only band X". The answer is it's not. I mean yeah it is if you chose to live in your fantasy world and continue to ignore the evidence that you are wrong and the world around you is in fact having problems people claim they aren't having.

          • No. It's a few hundred MHz lower thanks to a larger guardband from the affected devices. And still a problem.

            If aviation equipment was sensitive to out of band emissions (and not just out of band, but hundreds of MHz out of band) and this was known years ago, they should have done something about it years ago. It's not enough the flying buses get to monopolize the skies, they get to monopolize the spectrum as well?

          • You mean the aircraft equipment is so bad that it is sensitive to radio transmissions several hundreds of hertz away from its designated spectrum? Then that equipment is at fault and shouldn't be allowed
            • by Entrope ( 68843 )

              You would be extremely hard-pressed to find RD equipment that isn't considerably sensitive to "transmissions several hundreds of [H]ertz away from its designated spectrum".

              In this case, the equipment is sensitive to transmissions several hundred megahertz away, but considering the age of the designs and the previous uses of that spectrum, that susceptibility is not unreasonable. Regulators are radically changing the environment.

      That's because almost all the roll out in the US of 5G.. Isn't.

      It's 3G or 4G base transmission speeds at best over 5G frequencies. The infrastructure of the phone companies is horribly out of date, basically.

      The US has the best coverage for 5G so far from what I read, but also the lowest speeds of any western country that rolled it out.

    • Nope.
      Cancel all flights.
      Those aircraft are unsafe.

  • Just exactly what is the government going to do in two weeks? Have a meeting to discuss extending the two weeks?
  • It interferes with the altimeter used for low visibility landings. Small differences in the readings can produce catastrophic outcomes.
    • by butlerm ( 3112 )

      The problem is the FAA should have approved non-defective radio altimeter designs that stayed within their allotted bandwidth decades ago, instead of ones that splat (and receive) signals from all over the nearby spectrum.

      • In a nice easy make-believe world the radio pulse goes down from the aircraft, bounces off a nice perpendicular ground and returns to the aircraft with a predictable Doppler shift easy-pease. In the real world the ground is cluttered with multiple non-perpendicular reflective surfaces, unknown numbers of radio transmitters both moving and stationary, other aircraft all bouncing radio signals over unknown multiple paths heterodyning signals adding and subtracting from each other.
