Scientists transmit data wirelessly at 2.5Tb/s

So optical vortices are super interesting, but imho they are too sensitive for real data transmission. E.g. if you have an optical vortex with OAM of 2 or higher, a perturbation in your fiber will split it into a bunch of OAM of 1 beams, so you've lost everything. Another thing is that you need to read the beam exactly head-on - you can't afford missing the pitch or yaw by a fraction of a degree. While this makes these beams super secure, they don't make them very convenient to use.

Also, you guys should read about how the signal was "read" - likely they overlapped the OAM beams with a different beam (probably some plane wave) forcing the beams to physically separate in space. I don't see how you can claim this is "infinite capacity" if you literally need a physical separation in order to multiplex or demultiplex your data. And then how do you read it - with a camera hooked up to a computer at the end? BAM - there goes your 2.5 Tb/s!

This was a proof of concept, (a cool one) and is extremely unlikely to become the next generation of technology, if you ask me.
 
....which is why more gifted individuals than yourself seemed to have figured it out.

Don't think they would have published the results if it was impossible. Reputations are not easily repaired in the scientific community.

I think Saffakanera's opinion is quite well informed. This is the kind of article that says: We can do this, in this way, and it works. It is still on the science side of life, rather than on the engineering side. Let's just hope it becomes feasible for the industry.

Currently their range is about 1m, which isn't practical for any modern comms network. Much is possible that is not necessarily practical ... yet. It would be interesting to see what the effects of your traditional MW noise sources would be on the signal - fading, scattering, multipath...

Then praise the Lawd that I blew mine ten years ago... Would this technology perhaps include the use of lasers? Lasers that cause multitudes of spherical holograms to hang in the air about our property? Could the photographic evidence of such technology include photos of eerie swirls of vapour/smoke shaped in circles or swooping figure of eights, or spirals? If ever you're in my area, you're welcome to come see my pictures, just call in advance. Jane.
 
Dayem! I tried editing my initial post but have left it too late. It's gone all quiet in here for some reason, but I'll ask anyways.. It looks as if the lasers in our home are attracted to the wall mirrors as I'm getting some stupendous results in the reflections. I'll ask again - anyone know enough about the laser technology to offer a bit of help? J.
