Encoding many channels on the same frequency through radio vorticity: first experimental test
Twisting of light around rotating black holes
Utilization of Photon Orbital Angular Momentum in the Low-Frequency Radio Domain
“This novel radio technique allows the implementation of, in principle, an infinite number of channels in a given, fixed bandwidth.”
Sounds like a good reason to hand out FCC licenses like candy, once they’ve got this perfected and commercially available.
How about, every smartphone use gets an FCC license to transmit audio and video on a unique frequency/angle, kicked up to a nationwide network of cellular re-transmitters, with all the other smartphones having the capacity to pick up each other’s broadcasts? Goodbye media stranglehold. Just follow what stations you like, just like twitter.
This will mean the potential to “unclog” much of the spectrum limits of cellphone towers and Wi-Fi routers, making it possible to have a lot more people running 3GPP LTE on cellphones without running into spectrum limits.
