5G could mean less time to flee a deadly hurricane, heads of NASA and NOAA warn

It's increasingly clear that the wireless industry is trying to push the idea of fast 5G wireless networks before the technology is really ready. It's a race, and the race is nonsense. But until today, we had not realized that people's lives could also be at stake.

As reported by The Washington Post and CNET the heads of NASA and the National Oceanic and Atmospheric Administration (NOAA) warn that The problem could delay the world's prediction of weather by 40 years, which reduces our ability to predict the path of deadly hurricanes and the amount of time available to evacuate.

It's because one of the key wireless frequencies destined for fast 5G millimeter wave networks (the 24 GHz band) are very close to the frequencies used by microwave satellites to observe water vapor and detect those changes in the weather. They have the potential to interfere. And according to the testimony of NASA and NOAA, they could interfere to the point of delaying preparation for extreme weather events.

Last week, NOAA's interim chief, Dr. Neil Jacobs, told the House Subcommittee on the Environment that he relied on the current release of the 5G plan, our satellites would lose about 77 percent of the data they are currently collecting, reducing our forecasting capacity by up to 30 percent.

"If you look back in time to see when our forecasting ability was 30 percent less than today, it is somewhere around 1980. This would result in a reduction of the hurricane forecast advance time in about 2 to 3 days, "he said.

If we had not had that information, Jacobs added, we could not have predicted that the deadly Hurricane Sandy would hit. A European study showed that with 77 percent less data, the model would have predicted that the storm would remain at sea instead of landfall. Jacobs said later that we currently do not have other technologies to passively observe water vapor and make these predictions more accurate.

On April 19, NASA Administrator Jim Bridenstine made similar comments to the Scientific Committee of the House of Representatives. "That part of the electromagnetic spectrum is necessary to make predictions about where a hurricane is going to land," he told the commission. "If you can not make that prediction accurately, then you will not evacuate the right people and / or evacuate people who do not need to evacuate, which is a problem."

None of this should come as a surprise to the industry or the FCC, since experts have been debating this point for years in 5G accumulation. In fact, recent versions of the 3GPP Specification 5G NR specifically have an exception to protect satellite weather services, by reducing the emission levels of neighboring 5G signals between 24.25 and 27.5 GHz. "6.5.3.2.2 Additional non-essential emission requirements for NS_201", if you search).

But NOAA argues that emissions requirements are not enough; You will lose that critical data unless you tightened it even further. "I am optimistic that we can find an elegant solution where passive microwave and 5G detection can coexist," said Jacobs.

The FCC has definitely been warned, by the way: Space News reported that Secretary of Commerce and Bridenstine of NASA, Wilbur Ross, sent a letter to the President of the FCC, Ajit Pai, to talk about the protections on February 28, a couple of weeks before the FCC started auctioning the 24 GHz spectrum on March 14, but Pai rejected the invitation, claiming there was no "technical base" for an objection. "

Senators Ron Wyden (D-OR) and Maria Cantwell (D-WA) also sent a letter to Pai on May 13: "To continue on the road the FCC is currently on, to continue ignoring the serious alarms that the scientific community is generating could have dangerous impacts on the national security of the United States, the American industries and the American people, "they warned, and they asked Pai not to award any prizes. Fine l 24 GHz grants licenses or allows operators to operate in the 24 GHz band until it can protect satellite measurements from the way NASA and NOAA believe they need protection.

And earlier this week, the wireless industry trade association CTIA tried to ridicule the applications as false news, by publishing an argument about how the claims of the scientific community were based on a 13-year-old weather sensor that It was never really used. That was quickly refuted by meteorologist Jordan Gerth, who pointed out on Twitter that a different 23.8GHz sensor, the JPSS, replaced it:

We have not yet seen the study to confirm if the CTIA is in the truth when affirming that the study was based on the oldest sensor and if the new one would make a difference, but a CTIA spokesperson argues that the newer sensor is less sensitive to the interference of 5G signals.

For now, you will have to decide if you are more inclined to trust the heads of two respected scientific agencies, or the groups that benefit from the implementation of 5G as quickly as possible.
