AT&T and Verizon called the airline industry’s 5G bluff — until they didn’t

AT&T and Verizon agreed to another 5G deployment delay. The FAA now has two weeks to resolve safety concerns, but it just recently estimated the process could take three months.

In the latest step of an ongoing saga, AT&T and Verizon this week agreed to further delay the deployment of 5G C-band spectrum following requests from the Federal Aviation Administration. The wireless carriers only agreed to a two-week delay, however, which could still allow them to expand their 5G services before the end of January as planned.

AT&T and Verizon originally intended to use their C-band spectrum as early as Dec. 5, 2021. They agreed to a 30-day delay in November due to FAA concerns about C-band deployments potentially interfering with high-performing radio altimeters used to safely land aircraft in hazardous conditions.

Then, on New Year's Eve, Transportation Secretary Pete Buttigieg and FAA Administrator Steve Dickson sent a letter to the CEOs of AT&T and Verizon asking for yet another extension. Their proposal set a goal for full C-band deployment by the end of March, “barring unforeseen technical challenges or new safety concerns.”

The wireless executives were understandably miffed by the second extension request. They insisted that the C-band deployments wouldn’t interfere with airplane equipment, citing a Federal Communications Commission review process that wrapped up in 2020. As a concession, AT&T and Verizon also agreed to further limit the range of spectrum they use until July 5, 2022. France has adopted this more generous spectrum buffer, and the letter points out that U.S. airlines already fly there on a regular basis.

AT&T and Verizon likely agreed to the two-week extension because they understood the federal government could step in and block the rollout either way. While the negotiations between the FAA and the wireless carriers are indeed still “voluntary,” the threat of direct legal intervention underscores them.

The conflict highlights a lack of coordination between two powerful government agencies: the FAA and the FCC. The FCC raised a record-breaking $80.9 billion from the C-band auction that concluded in February 2021, and Verizon and AT&T together accounted for around 85% of the total spending. And while the FCC sold the spectrum under the assumption that airplane equipment interference was a non-issue, the FAA and U.S. airlines evidently weren’t on the same page.

The highly coveted C-band spectrum exists in the sweet spot for 5G. C-band has a longer range than the ultra-fast mmWave spectrum that’s still largely confined to cities and sporting venues. At the same time, C-band is significantly faster than the low-band spectrum, which sometimes isn’t even all that much faster than existing 4G LTE. In their response denying the FAA’s second delay request, AT&T and Verizon executives cited the U.S. government’s determination that China had more advanced 5G deployment in part because U.S. carriers lacked access to the best-suited spectrum.

President Joe Biden on Tuesday released a statement characterizing the new agreement as “a significant step in the right direction.” He signaled that this would be the final delay for the wireless carriers, writing: “This agreement ensures that there will be no disruptions to air operations over the next two weeks and puts us on track to substantially reduce disruptions to air operations when AT&T and Verizon launch 5G on January 19th.”

The big outstanding question, however, is what the FAA will do in the next two weeks to address their safety concerns. After all, they estimated on New Year’s Eve that it could take until the end of March 2022 to conduct all the safety measures. Another delay request could cause the “voluntary” negotiations to spill over into the courts. It would also heighten the spectacle of incompetence as two essential government agencies further contradict one another with billions of dollars at stake.


A pro-China disinformation campaign is targeting rare earth miners

It’s uncommon for cyber criminals to target private industry. But a new operation has cast doubt on miners looking to gain a foothold in the West in an apparent attempt to protect China’s upper hand in a market that has become increasingly vital.

It is very uncommon for coordinated disinformation operations to target private industry, rather than governments or civil society, a cybersecurity expert says.

Just when we thought the renewable energy supply chains couldn’t get more fraught, a sophisticated disinformation campaign has taken to social media to further complicate things.

Known as Dragonbridge, the campaign has existed for at least three years, but in the last few months it has shifted its focus to target several mining companies “with negative messaging in response to potential or planned rare earths production activities.” It was initially uncovered by cybersecurity firm Mandiant and peddles narratives in the Chinese interest via its network of thousands of fake social media accounts.

Some of the most astounding tech-enabled advances of the next decade, from cutting-edge medical research to urban traffic control and factory floor optimization, will be enabled by a device often smaller than a thumbnail: the memory chip.

While vast amounts of data are created, stored and processed every moment — by some estimates, 2.5 quintillion bytes daily — the insights in that code are unlocked by the memory chips that hold it and transfer it. “Memory will propel the next 10 years into the most transformative years in human history,” said Sanjay Mehrotra, president and CEO of Micron Technology.

Ripple’s CEO threatens to leave the US if it loses SEC case

CEO Brad Garlinghouse said a few countries have reached out to Ripple about relocating.

"There's no doubt that if the SEC doesn't win their case against us that that is good for crypto in the United States,” Brad Garlinghouse told Protocol.

Ripple CEO Brad Garlinghouse said the crypto company will move to another country if it loses in its legal battle with the SEC.

Garlinghouse said he’s confident that Ripple will prevail against the federal regulator, which accused the company of failing to register roughly $1.4 billion in XRP tokens as securities.

The Supreme Court’s EPA ruling is bad news for tech regulation, too

The justices just gave themselves a lot of discretion to smack down agency rules.

The ruling could also endanger work on competition issues by the FTC and net neutrality by the FCC.

The Supreme Court’s decision last week gutting the Environmental Protection Agency’s ability to regulate greenhouse gas emissions didn’t just signal the conservative justices’ dislike of the Clean Air Act at a moment of climate crisis. It also served as a warning for anyone that would like to see more regulation of Big Tech.

At the heart of Chief Justice John Roberts’ decision in West Virginia v. EPA was a codification of the “major questions doctrine,” which, he wrote, requires “clear congressional authorization” when agencies want to regulate on areas of great “economic and political significance.”

Microsoft and Google are still using emotion AI, but with limits

Microsoft said accessibility goals overrode problems with emotion recognition and Google offers off-the-shelf emotion recognition technology amid growing concern over the controversial AI.

Emotion recognition is a well-established field of computer vision research; however, AI-based technologies used in an attempt to assess people’s emotional states have moved beyond the research phase.

Microsoft said last month it would no longer provide general use of an AI-based cloud software feature used to infer people’s emotions. However, despite its own admission that emotion recognition technology creates “risks,” it turns out the company will retain its emotion recognition capability in an app used by people with vision loss.

In fact, amid growing concerns over development and use of controversial emotion recognition in everyday software, both Microsoft and Google continue to incorporate the AI-based features in their products.

“The Seeing AI person channel enables you to recognize people and to get a description of them, including an estimate of their age and also their emotion,” said Saqib Shaikh, a software engineering manager and project lead for Seeing AI at Microsoft who helped build the app, in a tutorial about the product in a 2017 Microsoft video.
