Around here, they are deploying 5G in frequency bands used for plain GSM for twenty years, but are now released to 5G.

The tinfoil hatters were complaining when GSM came onto the scene that it was neither the band nor the signal strength that made it dangerous, but the digital signal being carried. That resulted in a different shape of the modulated beam. This shape was something new and probably causing cancer and headache and dental cavities. The effects never materialized, but maybe these new signal shapes resulting from 5G modulation are the ones causing a new pandemic that makes Corona look like a small cold.

Actually, we have seen a significant reduction of radiation levels the last few years. When I bough my first GSM, our city of approx 200,000 inhabitants had two base stations, up on mountaintops overlooking then entire town. I don't know the emitted power, but the signals covered a radius of at least 15 km. Today, the city is broken up into three or four hundred tiny cells: The downtown area, about 2 by 3 km, has more than 200 base stations alone, each covering maybe 100-200 m distance. So the emitted power is a small fraction of the early bases: They can't increase power, as it would interfer with the next cell reusing the same frequency.

The old base stations were omidirectional, spreading their radiation all over the landscape. Modern bases track the direction to the phone using the current time slot, and directs the energy that way. Ideally, no energy is wasted in other directions, no radiation. (Again, this is to reduce interference with other nearby cells on the same frequency.) This significantly reduces average radiation levels.

We will soon be using higher frequencies. The highest 4G frequcy used here is in the 2.1 GHz band; for 5G, the 3.5 GHz will also be used. As you go into those frequencies, there is very little use raising the transmission power - you are approaching "line of sight" frequencies. Signals are stopped by the first hill or concrete wall anyway. You might as well plan for tiny cells, which are coverered with very little power.

The greatest reduction in human-made radiation was FM turnoff, replacing it with DAB. The main broadcasting tower around here had three 60 kW transmitters for the main radio channels, two 20 kW for supplementary channels - 220 kW transmitted power for five channels. DAB reduced that to a single 20 kW transmitter for 14 channels. Furthermore, in areas where the signal level is too low, as supplementary transmitter is set up adding to the weak signal what is needed - it doesn't have to provide a full strenght signal by itself. In principle, DAB allows the entire country to be covered with a blanket of just slightly avove the minimum signal level, magnitudes below the level emitted by that 220 kW FM tower.

Certainly we are moving into a time when we will see a lot of radiation burns. Those are caused by radiation in the 400 to 700 nanometers range, not in the 10 centimeter range.
