"Jordan Gerth, a research meteorologist at the University of Wisconsin, Madison, has been studying this issue as part of a group at the American Meteorological Society. He says that while the FCC can switch which regions of the spectrum it allocates to phone companies, forecasters are stuck. That’s because water vapor emits a faint signal in the atmosphere at a frequency (23.8 GHz) that is extremely close to the one sold for next-generation 5G wireless communications (24 GHz). Satellites like NOAA's GOES-R and the European MetOp monitor this frequency to collect data that is fed into prediction models for upcoming storms and weather systems."
