The essential thing about these new wireless technologies is that several features of their design (i.e., power management, beam-forming, massive MIMO) make their antennas radiate much less than existing 2G, 3G, 4G technologies in all directions but much more in the direction of the 5G equipped user. What does it mean? It means that if you do not have a 5G device in your home or your hand, there will be only minimal radiation from the 5G base station (including satellites). It also means that, if you use a 5G device, the power density radiated in your direction from the base station will depend significantly on the amount and speed of data you require. Consequently, if you are standing with a friend and he is watching a 4K movie on a new sparkly 5G smartphone, then you both are radiated a hell of a lot more than while your friend is doing a phone call or texting. Most people do not realize that radiated power densities needed for transmitting high-resolution movie are thousands of times higher than those required for a phone call. So here is a truth bomb - in a 5G world, beware of people around you, beware of what are they doing with their 5G toys of destruction. They will be killing you hardly softly each time they are around.
