An article appeared in the journal Nature between April and May 2019, which criticized 5 G, not so much in terms of health as in terms of reliability in weather forecasting. While there is still no effective response, the first indications seem to suggest that some of the frequencies used for 5 G may interfere with proper identification of water vapor current in the atmosphere.
The situation has now reached a turning point when FCC, NASA and NOAA positions clashed during a meeting of the US Congress. The first (Federal Communications Commission) is the U.S. body responsible for selling and assigning frequencies, while NASA requires no implementation, while NOAA (National Oceanic and Atmospheric Administration acronym) is the organization that also deals with meteorology and climate science.
5 G: The FCC is not persuaded by the NOAA study As reported, although NASA and NOAA are very critical of the use of frequencies around 23,8 GHz (a frequency also used for water vapor detection) for 5 G, the FCC has already completed its assignment to public tenders carriers.
The FCC holds, through its greatest representative, that the NOAA research is flawed and that the organizations submitted the grievances with guilty delay. In addition, it should be noted that the 5 G will use antennas that send the signal to the device accurately and should therefore not generate disruption in the surveys.
There will always be a distinction of 250 MHz compared to passive meteorological sensors to mitigate the possible issues. Thousands of fixed microwave links would also have been in use for some moment in bands below 23.8 GHz without causing issues.
However, with the present boundaries, a loss of 77 percent of the data could occur, according to reports from NOAA and NASA. This not only applies to the frequencies used, but also to the signal level that could reach -20 dB, while bringing it to-50 dB would be crucial, which would decrease the losses to almost zero.
According to the statements, if the current 5 G boundaries were to be maintained, tornadoes and other storms could be detected correctly, particularly when they touch the continent. The specialists would consider two (presently non-public) research that would demonstrate the technology's potential effect.
Jessica Rosenworcel (the Democrats ' FCC commissioner) said the situation was awkward. What is being criticized is the fact that these points on the 5 G would first have had to be clarified and then the auctions opened to sell the frequency slots.
