Global 5G deal poses significant threat to weather forecast accuracy, experts warn
A long-awaited international deal governing how the world's technology companies should roll out 5G technology poses serious risks to weather forecast accuracy, according to data from federal agencies and the World Meteorological Organization.
Negotiators from around the world announced a deal Friday at a meeting in Sharm el-Sheikh, Egypt, for how to roll out 5G technology that operates using specific radio frequency bands.
Studies completed before the negotiations by U.S. government agencies such as the National Oceanic and Atmospheric Administration, NASA and the Navy had warned that 5G equipment operating in the 24-gigahertz frequency band could interfere with transmissions from polar-orbiting satellites used to gather weather data. This could make forecasts much less reliable, the reports found.
Specifically, these highly technical analyses concluded that if deployed widely and without adequate constraints, telecommunications equipment operating in the 24 GHz frequency band would bleed into the frequencies that NOAA and NASA satellite sensors also use to sense the presence and properties of water vapor in the atmosphere, significantly interfering with the collection and transmission of critical weather data.
The NOAA report, for example, warned of a potential loss of 77.4 percent of data coming from microwave sounders mounted on the agency's polar-orbiting satellites.
The agency's microwave sounders operate at a frequency of 23.6 to 24 GHz, which is close to the frequency that the Federal Communications Commission auctioned off the use of for about $2 billion beginning this past March.
The key concerns about 5G interference focus on what are known as baseline interference limits, often referred to as out-of-band emission limits.

But this 5G will make people's weather apps run faster... Weather sites will have some awesome animations, even if they have to make up the data, because the satellite signals got washed out.

Yeah...., for the 5% of the population that get to have 5G. The rest of us will get "5G", actually 4G LTE.

We don't need weather, because everyone already works from home. America is the management headquarters of the world, and highly paid highly skilled Americans don't need to go outside to tell unskilled Chinese to make our stuff and unskilled Mexicans to mow our lawns and unskilled Indians to code our apps.

These so-called "experts" are just Soros employees working with the traitors at NOAA, trying to destroy the president.
It wasn't enough to fake the weather maps and try to defame the president before Hurricane Dorian, which hit Alabama harder than any other place in the world. And the lying media didn't show all the death and destruction there. Over 1,000 people died and tens of thousands were left homeless.
But the MSM doesn't care about Alabama, all they care about is making sure the fat cats who are hiding Epstein and ruining the nation have their solid gold bidets and baked kale. Scum!
Now they're trying to destroy our economy in advance of next year's election to sabotage the greatest president we've ever had.
Because the democunts hate America and want to destroy our way of life so Ilhan Omar's boyfriends (all 2,000,000 of them -- the whore) can run rampant all over our country bringing crime, violence disease and death to real Americans.
But we know better and we'll make sure we keep America great!

I suspect the person behind that account is still around, just posting under another account and as AC. I'm guessing he either got bored with it, or even he couldn't stomach that scumbag's duplicity and self-serving conduct any more.

Yes, but a fairly complicated MATLAB simulating base stations, user terminals, satellites and the geometries between them.
The study results map power levels to percent loss.
The last page says -20dbW/200Mhz causes interference above their threshold 77% of the time.
It's not clear what the consequencs of exceedit the threshold is or what powerlevel is being authorized.
Also, the sim assumes a particular antenna geometry. Does the authorization guarantee this?
It seems like what would be fair would be for the authorization to happen with the new folks as a secondary basis that has to shutdown if it causes problems to the existing satellites.
Or fund any sat mods the make sense.
The new folks should take the risk that this will work.

While I'm no weather sat expert, it seems pretty clear that the weather frequencies were chosen based on physics--so changing the satellite to a different frequency doesn't make any sense at all.
