They keep reiterating "faster, faster". But the discussion is "laser" vs. "radio".
Surprise: both travel at the speed of light. Both are the same speed.
Hmmm.
Are they afraid of having to explain "bandwidth"?
Laser clearly has better bandwidth then radio in most cases right?
Higher frequencies = smaller wavelengths = ability to pack more information into the same wave.
That's why phones started using the very high upper microwave bands for 5G.
Right.
