The tech industry is already thinking beyond 5G

Tech people like to use "G"s to signify the next generation of technology, especially in the wireless world. There was 2G and 3G, today's 4G LTE and now we are on the brink of 5G.

Yes, but: Marketing people are always getting ahead of the technology people, jumping the gun to get an edge on rivals. It happened with 4G as T-Mobile and AT&T started putting the 4G label on what was essentially a speedier flavor of 3G. The same thing is happening with 5G, as AT&T is slapping the label "5G E" on existing devices that run on its latest 4G network, which it calls "5G Evolution."

Reality check: True 5G will require new devices to run on the new networks that are only just beginning to show up. The first true 5G smartphones are still a couple months away and will only support 5G in a handful of cities that carriers have picked for their first deployments.

But wait, it gets worse. Today, the research arm of the cable industry, known as CableLabs, is announcing a technology called 10G.

  • No, it has nothing to do with strapping two 5G phones together.
  • Rather it's the industry's term for 10-gigabit networks, the next generation of cable broadband due to start field trials in 2020.

Full disclosure: I'm part of the problem. Later this week I'm moderating a panel on 6G, exploring the use cases and technologies that will eventually prompt the industry to look beyond 5G, which we've barely started implementing.

Special report: War, fever and baseball in 1918

In January 1918, the horrors of World War I were in their final year, and Major League Baseball was preparing for its 16th season. But beneath the surface, another deadly battle was brewing. They called it the "Spanish flu."

The state of play: Over the next 15 months, the global pandemic infected an estimated 500 million people — about a quarter of the world's population at the time — and killed as many as 100 million.

Peter Navarro defends hydroxychloroquine use in heated CNN interview

White House economic adviser Peter Navarro defended the use of anti-malarial drug hydroxychloroquine to treat coronavirus during a CNN interview Monday, highlighting "the possibility" that it has therapeutic efficacy.

Why it matters: Navarro did not deny reporting from Axios' Jonathan Swan that he got into a heated exchange in the White House Situation Room over the weekend with infectious disease expert Dr. Anthony Fauci about the drug's prospects against the illness.

Special report: Health care workers vs. coronavirus

Health care workers are at an especially high risk of catching the coronavirus, because of their prolonged exposure to patients who have it. Making matters worse, the U.S. doesn't have enough of the protective equipment, like masks and gloves, that keeps them safe.

  • And yet these workers, with loved ones of their own, keep showing up at hospitals across the country, knowing that more Americans than they can possibly care for are depending on them.
