Problem is OAM does not work for long distances.
- mNovak 7y agoCan you elaborate? I've seen OAM at the conferences but not super familiar
- madengr 7y agoAs 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.
