Yes, this refers to the mmWave frequencies and is yet another argument for careful roll-out of 5G on those frequencies. Note that this is not the first time to have a situation in which a new wireless communication system is deployed in a way where one has to take care for the interference created to the incumbent service, in this case the weather forecast. During the first decade of the 2000s there was a lot of research on the concept of a cognitive radio that operates in a spectrum that can affect the operation of radars, which were incumbent in that spectrum. This requires so-called frequency-agile or dynamic access techniques, by which the newcoming system is obliged to avoid interference to the incumbent. Hence, 5G deployment and operation should be done in a way that protects weather forecast from interference.
