In a new breakthrough achievement the discovery has been made that by twisting light more data can be embedded in the transmission. In fact, twisted light may make wireless data faster than fiber. This opens the door to very high speed wireless networks but at the same time because it is an optical network I do wonder if weather patterns will negatively effect transmissions.
At the same time they tested it in a German urban environment where there wouldn't be a clear easy to transmit position.
They've discovered a way to 'twist' photons in a way that not only crams more data into each transmission, but survives interference from turbulent air. If you pass light through a special hologram, you can give photons an optical angular momentum that lets them carry more than just 1s and 0s -- and so long as the light's phase and intensity are right, you can reliably beam that data over long distances.
Apparently they could transmit over a 1 mile stretch. This reminds me a lot of LiFi and I suppose technically it is a form of LiFi. LiFi are technically the optical wireless transmission capability where light carries the binary information or packet information. The beauty of TCP/IP and the electromagnetic spectrum is that there are many options for embedding communications and some haven't been fully explored.
Awesome
Things are getting better. Good to know Dana.
Mad scientists ;-), you know.
I hope that they do some appropriate cancer testing on this technology. Especially if using higher frequency spectrum. But why let health get in the way of progress right?
I'm new on steemit. If you don't mind plz helo me sir..I cordially requested you plz help me sir.
Someday internet will be global and wireless, including sea, desert, mountains, literally everywhere. And extremely fast.
nice post. upvoted
For those interested:
The foundations of this technology were explored by Italian researchers in 2012 who actually began their efforts by calculating the effects that a black hole will have upon the angular momentum of light as it passes by.
