In the New Journal of Physics an article was published yesterday which shows a video demonstrating a technique of "twisting" the orbital angular momentum of a specific frequency of radio waves such that an unlimited number of radio channels (voice, or video) may use it.
A video explains the technique and shows a demonstration of it. It is simply amazing.
