Wiil 5G mobile networks wreck weather forecasting?

The new mobile phone frequencies disrupt weather satellites, apparently.

article is a bit misleading.
there are several frequencies that 5g can run on, and as far as i know, no telco is using the one next to the weather one.
also significant gap between the frequencies.

Weather is 22.5Ghz

Australian 5G is initially on 3.5 and 3.6Ghz and may eventually go to 26-28Ghz. Thats why we have a communications management authority

I do not think any Telco in Australia will get the frequency needed for humidity measurement. They might in the USA, where the denser population places more pressure on spectrum, but even there I doubt it will happen.

I thought weather forecasting was pretty wrecked already?

Now that was not very nice!

Admittedly this is in Germany, but doesn't Australia have to comply with the ITU. ?

"The problem is that the International Telecommunication Union (ITU) decided at its 2019 world conference (WRC-19) in Sharm el-Sheikh, Egypt, that the new 5G mobile network should operate in the range of 24.25 and 27.5 GHz.That leaves a slim 0.25 GHz of separation between 5G mobile telecommunications and that all-important water vapor range that meteorologists need to predict storms. It's almost inevitable that 5G — its send-and-receive masts and our mobile devices — will disrupt the flow of weather data to meteorologists."The emissions don't just stop at 24 GHz because every transmitting device has a certain range," says Simmer. "It's unavoidable with some bandwidths. There will be interference.""

I not one of those who believes that the forecast is never right. I am impressed with their accuracy. I often wonder whether some critics realise that a 40% chance of rain means a 60% chance of no rain.
The weather app I use can display the predicted temperature and the actual temperature. Most of the time the two graphs are almost identical.
I wonder if some people assume that a prediction of rain means that the rain will fall in their street rather than just somewhere in the forecast district. I have often seen evidence of rain less than 5km away when we got none.
I'm convinced a lot of people simply repeat the criticism because it is fashionable, not because it is true.
