Applied to microwaves in particular, modulating wave properties is how we transfer data. New ways to pack more bits per Hz are always useful.

Problem is OAM does not work for long distances.

[mNovak]

Can you elaborate? I've seen OAM at the conferences but not super familiar

[madengr]

As the beam diverges, you need larger and larger receive antennas to discriminate between the modes, more aperture than you need to compensate for path loss. That seems to be why OAM research is now mmWave (better collimating) and more applicable to short range backhaul.
