- More 5G towers operating in the same frequency/power range as 4G means less RF energy emitting from your Phone to the (now nearer) tower.
- The emissions from the towers to the phones should also be less, because A) they need to emit less energy to reach the (now nearer) handset, and B) the "fountain coding" in 5G means that less data packages need to be transmitted to carry the same data payload as 4G. Of course, this is counterbalanced by the probably higher data usage under 5G.
- Beam-forming millimeter-wave antennas cannot penetrate flesh, so won't try to establish links in that direction. Regular 4G frequencies do (and, use your head as an antenna element). So, transitioning from 4G frequencies to millimeter-wave should reduce the amount of your-head-is-an-antenna utilization for a set amount of data...
