This is infinite bandwidth everywhere without a ton of infrastructure. A world changer. Thinking of the possibilities will boggle your mind.
What amazes me is that this isn’t new technology. It took 20 years (the theory behind this is over 100 years old and OAM properties where proven in a lab 20 years ago) before an extremely small group decided to experiment and demonstrate orbital angular momentum practicability. With billions spent on bandwidth a bunch of telecomm CEOs should be slapping their heads in amazement at their stupidity.

Well.....hold on.
There has to be some minimum energy level to discern different levels of “spin”. Presently, in order to get highest spectral performance, you need to have a very strong signal (physics thing). What is not clear at first blush is how and to what degree devices can be made to detect differing levels of spin, and how frequency re-use impacts the density of spin-encoded channels.
Still....good stuff, but the engineer in me has to expect something significantly less than “infinite bandwidth”.
If they can make it viable, it sounds like it would 1000 times more revolutionary than fiber optics.
