Below is radio frequency chart from Wikipedia. Everywhere on the net, it is said that, as the frequency increases, they can't travel further, they face most obstacles, they get absorbed by oxygen, etc, this is the reason given for why 5G needs more towers, etc. If that is true, why are frequencies higher than 5GHz used in long distance communication, satellite communication, radar, etc.. This seems counter-intuitive to me. If higher frequencies can't travel further, then they shouldn't be used in long distance communication, radar, etc. So why are they being used in these things and why 5G frequencies are said to can't travel further?
