AT&T and Verizon forge ahead with new 5G deployments despite aviation industry fears

AT&T and Verizon are moving ahead with the deployment of their midband 5G spectrum as planned, rejecting a request by senior U.S. transportation and aviation officials to delay the rollout by a couple of weeks.

According to Reuters, U.S. Transportation Secretary Pete Buttigieg and Federal Aviation Administration (FAA) Chief Steve Dickson contacted AT&T CEO John Stankey and Verizon CEO Hans Vestberg late last week, asking them to delay the commercial deployment of the new frequencies for “no more than two weeks.”

On Sunday, the wireless companies issued a joint letter, stating that they would be moving ahead as scheduled on January 5, although they did agree to avoid deploying any new 5G towers near airports for a period of six months. This would provide an “exclusion zone” similar to that used in other countries like France, they said. However, the two CEOs were emphatic that agreeing to the proposal by the U.S. Department of Transportation would be “an irresponsible abdication of the operating control required to deploy world-class and globally competitive communications networks.”

Early last year, AT&T and Verizon successfully acquired substantial chunks of new C-band spectrum put up for auction by the Federal Communications Commission (FCC). Over the past year, however, they’ve been facing concerns from a number of commercial aviation groups that these new 5G frequencies sit perilously close to those used by aircraft equipment.

Opponents of the plan have warned that such interference could cause instrument failures that could potentially lead to collisions. These concerns originally led the FAA and the U.S. Department of Transportation to call on the FCC to pause the auction to give them time to investigate the issues in greater detail.

The FCC disputed many of the claims that suggested that the new 5G frequencies posed a risk to aircraft equipment, suggesting that they were far enough away to avoid any interference. They also pointed to the use of these frequencies in about 40 other countries without incident. The spectrum auction went ahead, and AT&T and Verizon prepared to roll out the new midband 5G starting in December.

Shortly before that happened, however, both carriers agreed to delay those rollouts into early 2022 “in the spirit of good faith,” as Verizon officials put it. They agreed to work with the FAA and try to address some of its concerns, and even proposed 5G midband power limits to help avoid interference and lower the midband signal power even more near airports and helipads.

At this point, however, it would seem the carriers aren’t willing to brook any further delays. They insist that the proposed exclusion zone should be more than sufficient to quell the fears of the FAA and other aviation industry officials.

As the CEOs wrote in their joint letter to the FAA, “The laws of physics are the same in the United States and France,” so “If U.S. airlines are permitted to operate flights every day in France, then the same operating conditions should allow them to do so in the United States.”

The FAA responded in a statement to Reuters, saying that it was “reviewing the latest letter from the wireless companies on how to mitigate interference from 5G C-band transmissions,” adding that “U.S. aviation safety standards will guide our next actions.”

FAA officials also noted that the spectrum used for midband 5G in France sits farther away from those used by aircraft instruments and also operates at a lower power level than what’s authorized in the United States. Verizon has agreed to confine its spectrum to the same range during the initial rollout and create a larger exclusion zone around U.S. airports “to make up for the slight difference in power levels between the two nations.”

Aviation industry officials remain skeptical, however, suggesting that the proposed exclusion zones still aren’t large enough and that the carriers and the FCC haven’t properly addressed other safety concerns.

In a post on Twitter, Sara Nelson, president of the Association of Flight Attendants-CWA (AFA), which represents 50,000 workers at 17 airlines, suggested that her members would refuse to fly if safety questions remain unanswered.

Tagging @Verizon and @ATT. We’re all for 5G, but not at the expense of safety. We can’t/won’t fly if there’s a question. Time to stop the brinksmanship, share the information, and plan to allow 5G and aviation to coexist. We won’t allow the traveling public to be Guinea pigs.

Airlines for America, a trade group that represents American Airlines, FedEx, and other carriers, has also formally asked the FCC to completely halt any midband 5G deployments around many airports, warning that thousands of flights could be disrupted. The group has threatened to take the matter to court this week if the FCC doesn’t act immediately to work with the FAA and the aviation industry to “enable the rollout of 5G technology while prioritizing safety and avoiding any disruption to the aviation system.”

Verizon’s new Welcome Unlimited plan makes 5G data a lot more affordable

Verizon is rolling out an even more affordable 5G plan for customers looking for unlimited data without all the extra frills in its Mix & Match plans.

For as little as $30 per month for each line (when signing up for four lines with Auto Pay), the new Welcome Unlimited plan includes all the basics that most users need — including unlimited data, talking, and texting. The plan is separate from Verizon's Mix & Match Unlimited plans and lacks the features of those more expensive options, such as mobile hotspot data and streaming service bundles.

T-Mobile’s 5G network just beat Verizon and AT&T (again)
T-Mobile smartphone.

T-Mobile, Verizon, and AT&T always claim to be America's best 5G network in their commercials. T-Mobile boasts this even more so, and as it turns out, it's true. During PCMag's annual Best Mobile Network test (previously known as the Fastest Mobile Network test), T-Mobile won over Verizon and AT&T as the Best Mobile Network for the second year in a row.

PCMag gave T-Mobile the title after testers drove 10,000 miles across the country to measure its performance against Verizon and AT&T. The test involved driving to 30 cities and six rural regions to test each mobile carrier's reliability using Samsung Galaxy S22+ smartphones. As expected, T-Mobile won that contest in 18 cities out of 30, followed by Verizon with eight and AT&T with four.

5G coverage map: Where you can get 5G on Verizon, AT&T, T-Mobile
Qualcomm 5G at CES 2019

Gone are the days when 5G was just a buzzword and deployment was experimental. Today, 5G is an established worldwide networking protocol built into most high-quality and flagship mobile devices. 5G stands for fifth-generation mobile technology, and it's destined to replace 4G (and older protocols) worldwide with speeds up to 100 times faster.  Not only is it faster, but it is also more responsive for overall coverage and reception. That means faster uploading and downloading of documents, images, and videos. For home use, it means replacing fiber-optic cable with fast wireless connections.

There are two forms of 5G technology currently in use: Sub-6 relies on lower frequencies to deliver a much larger network, but the trade-off is that you'll receive only marginally faster speeds than you would with 4G. While mmWave connections rely on much higher frequencies that deliver dramatically faster download speeds, those radio waves can't physically travel long distances or make their way through obstacles like walls or even windows, which reduce signal strength.
