So far, the consortium responsible for this has plans to reach up to around 80 GHz. However, the highest frequency bands are only suitable for a transmission in the direct proximity, for example from computer to screen. In this respect, this highest frequency range is not so relevant for electrosensitive people, because it is up to them whether they want to use such applications or not (once 5G is commercially available in this frequency spectrum in a few years).
The plans for 5G in the frequency range around 28 GHz are much more concrete. In this range, though, it is mainly a matter of the (temporary) coverage of, for example, soccer stadiums, shopping centers and the like, as well as wireless internet on railway lines and in public transport systems. Here, too, the range is very limited and, in order to minimize power consumption, providers will try to concentrate the radiation as narrowly as possible to the absolutely necessary range. However, the demonstrations so far have revealed major technical difficulties, because even a tree blocking the direct line of sight to the transmitter has led to considerable reductions in the transmission rate, and even to disconnections.
