Submission + - 'Twisted' waves could boost capacity of wireless spectrum (bbc.co.uk)

Ogi_UnixNut writes: In Venice, Italy, Physicist's have shown that it is possible to use two beams of incoherent radio waves, transmitted on the same frequency but encoded in two different orbital angular momentum states, to simultaneously transmit two independent radio channels.

In principle this allows the implementation of an infinite number of channels in a given, fixed bandwidth, even without using polarization, multiport or dense coding techniques.

Potentially a boon for congested spectrum problems, although at the moment I suspect it would only work for directional links.
