Here are some 5G trends for year 2020:
It looked like 5G and wireless dominated the airways in 2019. It seems that year 2020 will be a real test for 5G if it will really take on or fails to full-fill the big expectations. It seems that 5G networks are available at some place here and there from many operators, but 5G end user devices are not yet widely available or desired. New year will bring more 5G base stations.
5G: How Much is Real vs. Marketing? Is 5G ready for prime time? Breaking down the marketing hype versus what’s really going on in the industry. Marketing claims 5G is pervasive. The question is when: 2020 or is it 2025?
First, let’s define 5G also known as 5G New Radio, or 5G NR:
There is sub-6-GHz 5G for the cellphone protocol that requires LTE: 5G NSA.
There is sub-6-GHz standalone 5G: 5G SA.
There is 20- to 60-GHz 5G: 5G mmWave.
It seems that 2020 will be the real test for 5G devices as the 5G device mass market has not yet really started. Samsung says it shipped 6.7M+ Galaxy 5G phones globally in 2019, accounting for 53.9% of the 5G phone market (Galaxy S10 5G and the Galaxy Note 10 Plus 5G). 2020 is expected to be an interesting year for 5G growth across the smartphone market. Increased 5G rollouts by carriers means that customers will presumably be more interested in actually buying 5G devices. One June 2019 forecast made by Canalys has global 5G smartphone shipments crossing 4G smartphone shipments in 2023.
5G will be integrated to some PCs. Dell debuts a new Latitude 9510 laptop with built-in 5G, to launch March 26.
Ericsson says they are now 5G networks leader according to Ericsson ylitti odotukset kirkkaasti: ”Olemme 5g-johtaja” article. Nokia has cut its outlook for this year and next because of the need to step up its investments in 5G but ‘We don’t have a 5G problem,’ says Nokia’s head of software.
5G will be a good growing market for test device manufacturers as engineers will once again need to sharpen their skill sets and adopt new design and testing techniques. A lot of 5G Component Characterization and Test will be needed.Delivering 5G Devices to Market Will Bank on OTA Testing.
Network side needs also testing equipment. One approach being adopted to gain ground in the race to 5G involves the rapid prototyping and testing of network architectures. There is need for programmable RF devices. Industry seems to want their own private networks.
5G components are available from many sources already. The typical RF component suppliers are all providing 5G solutions: Avago/Broadcom, Huawei, MediaTek, Murata/pSemi (previously known as Peregrine), Qualcomm, Qorvo, Samsung, and Skyworks.
Challenges: Even the sub-6-GHz versions have technical issues in that the 5G target “air time” latency is 1 to 4 ms. Typical RF component manufacturers appear to be providing components that focus only on the sub-6-GHz frequency bands. The geopolitical situation relative to 5G also adds confusion to the 5G timeline.
There are many technical issues must be considered in the utilization of mmWave: mmWave frequencies travel relatively small distances. the mmWave transmitters consume a considerable amount of transmit power, providing additional challenges for battery-operated devices.
5G in automotive: The automobile industry is experiencing exponential growth of self-driving features, and this trend is expected to continue. 5G network connections are expected to have a major influence on the development of self-driving cars making them faster, smarter, and safer. Where is car technology going in 2020?
As 5G work has started for many installers and marketers, the the researchers are already thinking about the nest step Beyond 5G chips. They are already planning technologies that could enable high-speed wireless devices beyond the 5G standard.

Huawei demosi millisekunnin jatkuvaa latenssia
https://etn.fi/index.php/13-news/12982-huawei-demosi-millisekunnin-jatkuvaa-latenssia
Moni 5G-tekniikan lupaama sovellus edellyttää nykyisiä 4G-verkkoja lyhyempää latenssia. Tällaisia ovat esimerkiksi etäkirurgia, AR/VR-sovellukset tai robottien ohjaaminen verkon yli. Huawei on nyt saanut valmiiksi testit, joissa yllettiin jatkuvassa yhteydessä yhden millisekunnin latenssiin.
Gizchinan raportoimissa testeissä Huawei on yltänyt millimetriaalloilla 1 millisekunnin latenssiin 99,999 prosentin luotettavuustasolla. Käytännössä tämä tarkoittaa jatkuvaa nopeaa yhteyttä millisekunnin viiveellä. 5G-terminologiassa tästä puhutaan nimellä URLLC (ultra-reliable low-latency communication).

Global 5G wireless deal threatens weather forecasts
https://www.nature.com/articles/d41586-019-03609-x
Meteorologists say international standards for wireless technology could degrade crucial satellite measurements of water vapour.
Negotiators at a meeting of the International Telecommunication Union in Sharm El-Sheikh, Egypt, agreed to introduce two stages of protection for frequencies near 24 gigahertz — a range close to those that weather satellites use to detect the amount of water in the atmosphere. Companies that operate 5G networks will have a relatively loose standard from now until 2027. After that, the regulation will get stricter. The idea is to let 5G companies start building networks now, and then to add more protection for Earth observations as 5G transmissions become denser.
But having eight years with relatively lax regulation is “of grave concern” to weather forecasters, says Eric Allaix, a meteorologist at Météo-France in Toulouse who heads a World Meteorological Organization (WMO) group on radio-frequency coordination. The WMO is so upset that it read a statement of concern into the meeting minutes, he says.
“The race for 5G is going to go fast,”
Buffer zone
The 5G transmissions will involve many frequencies, but the key one under discussion is 23.8 gigahertz. Water vapour in the atmosphere naturally produces a weak signal at this frequency, which satellites use to measure humidity. Those data feed into weather forecasts. But if a 5G station is transmitting a signal near the 23.8-gigahertz frequency, a weather satellite might pick it up and interpret it as water vapour. And that bad data could degrade forecasts.
Meteorologists say that the problem is manageable, but only if there is enough of a noise buffer between the 5G transmissions and the water-vapour signal.
A study conducted by NASA and the US National Oceanic and Atmospheric Administration found that 5G base stations needed to transmit with a noise buffer of –52.4 decibel watts to protect the water-vapour observations.

The CEOs of Boeing and Airbus wrote to Pete Buttigieg Monday asking him to delay the rollout of 5G.
AT&T and Verizon are due to start rolling out their 5G services on January 5.
The two chief executives said 5G interference could affect planes’ ability to fly safely.
Chief executives at Boeing and Airbus, the two largest airplane makers in the world, have written to US Transportation Secretary Pete Buttigieg asking him to delay the rollout of 5G services for phones.
In the letter seen by Reuters, Boeing CEO Dave Calhoun and Airbus Americas CEO Jeffrey Knittel asked Buttigieg to postpone the planned January 5 deployment of AT&T and Verizon’s 5G services in the US.
“5G interference could adversely affect the ability of aircraft to safely operate,” the letter said, adding it could have an “enormous negative impact on the aviation industry.”
AT&T and Verizon were scheduled to roll out their C-band 5G services in November, but delayed the rollout until the January 5 date following airplane safety concerns voiced by the Federal Aviation Authority. The FAA said in November that 5G deployment could potentially cause interference with altimeters on airplanes, used to measure the altitude of aircrafts.
The FAA issued an order earlier this month detailing potential restrictions on using systems commonly deployed for landing in bad weather due to concerns around 5G interference, The Wall Street Journal reported.
A spokesman for a telecoms industry group has previously said concerns around 5G and airplane equipment are overblown.
“The aviation industry’s fearmongering relies on completely discredited information and deliberate distortions of fact,” Nick Ludlum, a spokesman for the wireless industry group CTIA, told The Wall Street Journal earlier this month.

Airlines warn of ‘catastrophic’ crisis when new 5G service is deployed
https://thehill.com/policy/transportation/aviation/590066-airlines-warn-of-catastrophic-crisis-when-new-5g-service-is
U.S. airlines and cargo carriers on Monday warned that the new 5G wireless service set to deploy Wednesday could ground flights, potentially stranding thousands of Americans overseas and delaying the delivery of key goods.
In a letter to Biden administration officials, executives of major carriers wrote that C-band 5G causes disruptions to airplanes’ instruments that could make “huge swaths” of the U.S. fleet unusable. They noted that by Wednesday’s deadline, most of the nation’s large airports will be under 5G-related flight restrictions from the Federal Aviation Administration (FAA).
“This means that on a day like yesterday, more than 1,100 flights and 100,000 passengers would be subjected to cancellations, diversions or delays,” chief executives of Delta Airlines, United Airlines, FedEx, UPS and others wrote in the letter.

They say 5g is launching in us in nextbfew days… Att snd verizon are waiting for the airline. But im confused. What 5 g were phones using this last yr?
The airline this is real. But only an issue if a plane needs to land in conditions that are not visual. Then they are told they can’t use radar altitude anymore with Cband on. It depends on the airport, it ground altitude radar is essential in some aircraft/airport/weather conditions.
Anyone in a commuter service for sure is not even taking off if it’s not visual.
As Arthur said, IFR is the normal landing procedure for commercial airliners, even under what private pilots would consider VMC.
On the one hand, the C-band frequencies being used under 5G are the exact same ones that have been in use for decades by satellite earth stations. On the other hand, there are only a few dozen satellite uplink transmitters per frequency across the whole Nortm American continent, as opposed to tens of thousands now that part of that band has been taken away from satellite users and reallocated to mobile.
One thing I find interesting is that no one is talking about how C-band radar altimeters are nearly obsolete as it is. Most modern systems use Ka, Ku, S, or a combination of the above.
yet the uk authority, where they already use c band, is calling it suspect.
It’s a different band of 5G, and there delaying starting it within a few miles of certain airports, not delaying the whole rollout.
It’s because the US were silly using 3.9GHz to 4.1-4.2GHz as part of their band C spec. Radio altimeters used in aircraft are in the 4.4GHz range. Harmonic crossover can therefore affect the instruments in some circumstances. The rest of the World uses 3.2-3.8GHz in their band C. The higher the frequency the fast the data can go.
You’d think the manufacturers would use another 15 cents in parts to add a filter on the input. But nah. Saw similar going on with GPS manufacturers a while back.
5G phones: How serious is the threat to US flights?
https://www.bbc.com/news/business-60042178
Ten leading US airlines are warning that the imminent rollout of 5G services could be disastrous.
They say the new technology could cause thousands of flights to be delayed, and risks leaving large parts of the US aircraft fleet grounded indefinitely.
5G relies on radio signals. In the US, the radio frequencies being used for 5G are in part of the spectrum known as C-Band.
These frequencies are close to the ones used by radio altimeters on aeroplanes, which measure the height of the aircraft above the ground, but also provide data for safety and navigation systems.
The concern is that interference from 5G transmissions could stop these instruments from working properly, and cause safety problems, particularly when aircraft are coming in to land.
How serious is the risk to planes?
It is potentially very serious.
In late 2020, the RTCA – a US organisation which produces technical guidance on aviation issues – published a report on the subject.
It said there was “potential for broad impacts to aviation operations in the United States, including the possibility of catastrophic failures leading to multiple fatalities, in the absence of appropriate mitigations”.
More recently, the US aviation regulator, the FAA, warned that 5G interference could lead to problems with a number of different systems aboard Boeing’s 787 Dreamliner.
These could make it difficult to slow the plane down on landing, causing it to veer off the runway.
How will flying be kept safe?
Planes won’t be allowed to use radio altimeters in circumstances where there could be a risk of serious interference.
But that will restrict the ability of some aircraft to land, for example, in poor visibility.
Airlines for America, which represents 10 major carriers, has warned that this could lead to more than 1,000 flights being delayed or cancelled in bad weather and mean at times “the vast majority of the travelling and shipping public will essentially be grounded”.
It has also suggested a large part of the US aircraft fleet will be “deemed unusable” because of restrictions on their operation.
Do other countries using 5G share these concerns?
Not to the same degree. That’s because the way in which 5G is being rolled out varies from country to country.
In the EU, for example, networks operate at lower frequencies than those which US providers are planning to use – reducing the risk of interference. 5G masts can also operate at lower power.
Nevertheless, some countries have taken further steps to reduce possible risks.
In France, there are so-called “buffer zones” around airports where 5G signals are restricted, while antennas have to be tilted downwards to prevent potential interference.
Tomi Engdahl says:
Airline CEOs warned that 5G signals could interfere with airplanes’ instruments, forcing flight delays and causing U.S. commerce to “grind to a halt.”
AT&T Delays 5G Rollout Near Some Airports After Airlines Warn Of Disruptions
https://www.forbes.com/sites/zacharysmith/2022/01/18/att-delays-5g-rollout-near-some-airports-after-airlines-warn-of-disruptions/?utm_campaign=forbes&utm_source=facebook&utm_medium=social&utm_term=Gordie&sh=c0d28f46c6fe
AT&T agreed Tuesday to delay activating 5G cellular data near some airport runways to avoid interfering with aircraft instruments, after airline CEOs warned this week’s 5G rollout would ground many commercial aircraft and disrupt flights.
AT&T plans to roll out its 5G network on Wednesday, aside from a “limited number” of towers within two miles of some runways, the company said in a statement Tuesday.
AT&T did not say how long it is willing to delay a complete rollout, and urged the FAA to find a way to safely accommodate 5G networks “in a timely manner.”
Emirates, Air India, All Nippon Airways and Japan Airlines announced they would cancel some flights to the U.S. due to uncertainty about 5G rollouts.
KEY BACKGROUND
5G signals near airports could interfere with the radio altimeters pilots use to measure how close they are to the ground, the FAA said last year. Though radio altimeters are a vital tool for pilots landing in low-visibility conditions, the agency in December ordered many commercial and commuter aircraft not to rely on them when experiencing 5G interference. On Monday, the heads of American Airlines, Delta Air Lines, FedEx and seven other aviation companies requested that 5G not be implemented within about two miles of airport runways. Otherwise, aircraft could be grounded, they warned, causing “catastrophic disruption” to travel and subjecting up to 100,000 passengers a day to cancellations or delays. Some airlines have considered canceling international flights scheduled to arrive in the U.S. on Wednesday, Reuters reported Monday.
10 aviation executives wrote Monday to federal authorities. “To be blunt, the nation’s commerce will grind to a halt.”
TANGENT
The Federal Communications Commission does not share the FAA’s misgivings about 5G. The FCC argued last year 5G signals don’t appear to interfere with airplane altimeters, pointing to several studies from Europe.

Ericsson sues Apple over infringement of 5G and other patents upon expiration of license agreement–Apple now facing an ‘Epicsson’ dilemma
http://www.fosspatents.com/2022/01/ericsson-sues-apple-over-infringement.html
Ericsson’s patent cross-license agreement with Apple has expired, and no renewal has been agreed upon, which is why infringement litigation became inevitable. IAM was first to spot two filings by Ericsson against Apple in the Western District of Texas over four patents in one case and eight in the other. Apple will predictably retaliate, but Apple’s exposure to patent assertions dwarfs Ericsson’s. When there was no announcement of a renewed license agreement or renewed litigation after the turn of the year, I thought the middle of the month was going to be when we would hear more.
Tomi Engdahl says:
There was an auction where anyone could buy the frequency spectrum. The airlines or equipment manufacturers were free to bid, but must have decided they’d modify their equipment for less cost. Now they’re just hiding behind “too big to disrupt”? These objections should have been raised BEFORE the spectrum was sold to the highest bidder.

The company is lighting up towers in just eight locations amidst pushback from airlines

AT&T is lighting up its expanded 5G service in just eight metro areas in the US on Wednesday, including Austin, Dallas-Fort Worth, Houston, Chicago, Detroit, Jacksonville, Orlando, and South Florida (PDF). This comes after both AT&T and Verizon voluntarily limited the activation of C-band spectrum around airports after facing mounting pressure from airlines.
“Today’s introduction begins in limited parts of 8 metro areas across the U.S. It will expand rapidly as our thoughtful and efficient deployment ramps up throughout the year,” Chris Sambar, AT&T’s executive vice president of technology operations, explains in the post announcing the expansion. “With 17 C-Band-capable devices already available online and in our stores, you can start seeing those speeds today.”
Just one day before Verizon and AT&T’s scheduled 5G rollout on January 19th, major airlines warned against activating 5G towers for fear of “catastrophic disruption” to flights operating across the country. Air India, Emirates, Japan Airlines, and ANA canceled some of their flights in advance over concerns that the 5G expansion could interfere with radar altimeters that aircraft use to make low-visibility landings. Ahead of the rollout, the Federal Aviation Administration (FAA) reached an agreement with both carriers to create 50 buffer zones where AT&T and Verizon will shut off transmitters for six months near airports with high traffic volume and frequent low-visibility conditions.
In a statement to The Verge, AT&T expressed frustration at the FAA’s failure to “utilize the two years they’ve had to responsibly plan for this deployment,” as well as its “inability to do what nearly 40 countries have done, which is to safely deploy 5G technology without disrupting aviation services.” AT&T and Verizon’s activation of the C-band spectrum has faced pushback by the FAA, resulting in two delays. And while AT&T is taking a more cautious approach to its rollout, Verizon plans on activating its network in 1,700 cities — covering 100 million more people — this month.

AT&T and Verizon temporarily restrict 5G expansion near US airports, but a few airlines will still suspend some flights on Wednesday amid Boeing’s guidance
Airlines Cancel Some Flights Ahead of U.S. 5G Wireless Launch
https://www.wsj.com/articles/at-t-will-avoid-airports-with-new-5g-service-to-prevent-flight-delays-11642528372?mod=djemalertNEWS
Flight suspensions occur even as AT&T and Verizon agree to limit signals within 2 miles of runways to address air-safety concerns
Two of the biggest U.S. wireless operators agreed to not turn on some 5G signals near airport runways, a temporary concession to address air-safety concerns that have already prompted international airlines to cancel some U.S.-bound flights.
AT&T Inc. T -0.11% and Verizon Communications Inc. VZ 0.13% on Tuesday afternoon accepted the new limits after a monthslong standoff between the cellular operators and aviation officials, who had promised to limit flights over concerns about the 5G signals’ effect on aircraft instruments.
President Biden on Tuesday thanked the wireless companies for the pause. “This agreement will avoid potentially devastating disruptions to passenger travel, cargo operations, and our economic recovery, while allowing more than 90 percent of wireless tower deployment to occur as scheduled,” he said.
Nevertheless, airline executives were left wondering whether the Federal Aviation Administration’s pending safety precautions would still ground their flights. Aviation-safety officials say the wireless carriers’ agreement will avert many—but likely not all—cancellations and delays. An FAA spokesman didn’t detail the extent of those delays.
Delta Air Lines Inc. said Tuesday evening that it is planning for the possibility of flight cancellations in certain weather conditions as soon as Wednesday, even after the agreement by Verizon and AT&T Tuesday. “
A handful of international airlines said Tuesday they planned to suspend some U.S. flights starting Wednesday, citing operational concerns stemming from 5G deployment and the FAA restrictions, as well as Boeing Co. ’s guidance not to operate the 777 wide-body jet.
Emirates Airline said it would suspend flights to nine U.S. cities. Japan Airlines Co. and All Nippon Airways Co. said Boeing had advised them not to operate the 777 to the U.S. in light of 5G deployment. Air India also announced the cancellation of some U.S.-bound flights operated by 777 jets.
An AT&T spokeswoman said the wireless company agreed to temporarily defer the turning on of a limited number of towers around some airport runways but would launch 5G services “everywhere else as planned.” Verizon later Tuesday also committed to limit its 5G network around airports, adding that the new high-speed service will still cover more than 90 million Americans when it goes live Wednesday.
The cellphone carriers’ next-generation wireless upgrades have sat in limbo in recent months after the FAA asked them to pause their 5G rollouts. The aerospace regulator said the frequencies AT&T and Verizon planned to use to carry the new 5G signals might confuse radar altimeters, which aircraft depend on to measure height off the ground.
Telecom-industry executives have disputed those claims and said that the service in dispute, which covers a set of frequencies known as the C-band, already operates around similar airwaves in dozens of other countries.
Aviation-industry officials said without an agreement, they could face limits on flying certain aircraft types, including being effectively unable to use Boeing 777 jets that fly internationally. Boeing declined to comment.
The telecom and aviation industries seemed on the brink of a truce earlier this month after cellphone carriers agreed to completely pause the launch of their new 5G services until Jan. 19. The timeout was designed to give the FAA more time to whittle down its safety restrictions to specific aircraft and airports, which would lessen the disruption they caused to flight plans.
But the FAA in recent days informed airlines that many airports expected to get some relief from the safety restrictions would still face sharp limits on landings in harsh weather.
AT&T and Verizon said they still plan to launch their high-speed network links nationwide Wednesday but will refrain from turning on signals within 2 miles of airport runways. Spokespeople for the companies declined to say how long the new wireless buffers around airports will last. They had previously agreed to dim the power of their 5G signals around runways for six months.
The partial launch has a deeper effect on Verizon, which is using the 5G frequencies in a larger number of locations. The 2-mile quiet zones will limit several hundred Verizon cell stations and about 10 AT&T stations, according to people familiar with the matter. T-Mobile US Inc. isn’t expected to activate its C-band services until late 2023.
The new 5G limits announced Tuesday will buy regulators more time but stop short of settling the issue. White House press secretary Jen Psaki said in a Tuesday media briefing that U.S. aviation and telecom regulators were working with industry representatives to develop a solution. “We certainly understand what’s at stake for both industries,” she said. “But certainly, minimizing flight disruptions, ensuring safety in travel is a top priority.”

“In October 2019, the FAA partially funded the Aerospace Vehicle Systems Institute (AVSI) to conduct preliminary bench tests to determine the interference impact from proposed 3.7-3.98 GHz 5G signals on a range of radio altimeter models. The results filed in the docket showed radar altimeter performance degradation for 5G signals, even at the 3.7 GHz band edge, with one widely deployed altimeter performing significantly worse than most others.”

AT&T and Verizon finally fired up vital components of their 5G networks in the United States on Wednesday. Mostly.
The two companies had already agreed twice to delaying the activation of the parts of their networks that operated on the so-called C-band, because the U.S. Federal Aviation Administration (FAA) had raised concerns about the spectrum’s usage.
Tomi Engdahl says:
The C-band stretches between either 4 to 8 GHz or 3.7-4.2 GHz, depending on who you’re asking. (The IEEE considers it to be the former, while the U.S. Federal Communications Commission says it’s the latter). Regardless, the issue is that swath of spectrum hovering around either side of that 4 GHz mark. Above it are the frequencies that airplanes use and below it are frequencies opened up for use by wireless network operators to meet the growing bandwidth demands of their 5G networks.
What’s the problem with 5G and planes?
FAA has raised specific concerns over airplanes’ radio altimeters, which help planes (and their pilots) determine how far above the ground an aircraft is by bouncing a signal off the ground below and timing how long it takes to return to the plane. Such data are crucial when the plane is taking off and landing, particularly when visibility is low: at night and in fog or rain.
Therefore anything that potentially messes with radio altimeter signals could be bad news. If other entities are using the same frequencies (between 4.2 and 4.4 GHz), altimeters could be affected and return incorrect altitude measurements or worse, have their signals blocked entirely.
It’s important to note that the C-band frequencies being used by AT&T and Verizon are not in that same 4.2 to 4.4 GHz band. Both companies’ C-band allotments are between 3.7 and 3.98 GHz. The concern raised by the FAA is whether those frequencies are too close.

Tomi Engdahl says:
In Europe, for example, 5G mid-band rollouts have proceeded without much concern for radio altimeters, because the spectrum allocated is at just slightly lower frequencies (3.4 to 3.8 GHz in Europe, as opposed to the mentioned 3.7 to 3.98 GHz in the United States). Meanwhile, countries like Canada have installed buffer zones like the ones AT&T and Verizon have agreed to. The Australian Communications and Media Authority has said it believes that a 200 MHz guard band (like the one in the U.S.) between 5G networks and radio altimeters is sufficient in itself.

AT&T, Verizon limit C-band rollout around airports while FAA evaluates altimeters.
Tomi Engdahl says:
They did not auction frequencies already in use, they auctioned frequencies very close to the ones in important use that they can cause interference (because filters on those existing equipment are not ideal in very effectively filter out strong close by out of used band other signals).

Emirates president calls 5G rollout fiasco the ‘most delinquent mess he’s seen in his entire career’ and blames Pete Buttigieg for doing nothing to stop the chaos after dozens of flights were canceled – and then uncanceled
https://www.dailymail.co.uk/news/article-10417587/British-Airways-latest-carrier-scrambling-change-transatlantic-flights-amid-5G-rollout.html
The president of Emirates has slammed the 5G fiasco as the ‘most delinquent, irresponsible’ mess he has seen in his 50-year aviation career and blamed it on Transport Secretary Pete Buttigieg, who he says knew about the impending chaos but failed to warn anyone in time to stop it.
AT&T and Verizon launched their 5G network across America on Wednesday morning, switching on 4,500 towers to bring faster wireless to their customers. They had to hold back on ten percent of the towers – 500 – that are near airports because the frequencies the towers emit could interfere with the signal on some planes.
Eighty-eight airports now have buffers to protect against it but some major airports like Boston and Memphis do not. In the most recent FAA announcement on Wednesday afternoon, the government said ’62 percent’ of flights could operate safely – leaving nearly half to reschedule.

The U.S. aviation and telecommunications industries are waiting for regulators to assess whether the rollout of 5G poses a safety risk for aircraft.
Airlines for America, which represents American (ticker: AAL), Delta (DAL), FedEx (FDX), UPS (UPS) and others, filed an emergency petition last week with the Federal Communications Commission to stop deployment of 5G in the U.S.
AT&T (T) and Verizon (VZ) announced Tuesday that they would delay the launch of the next-generation wireless technology by two weeks after a request from Transportation Secretary Pete Buttigieg. Verizon, at least, seems to hope that 5G will be up and running by the end of the month.
