Want Some Infinite-Capacity Wireless Vortex Beams?
New Tech Could Cure Spectrum Shortcomings -- ForeverTipped by WHT
American and Israeli researchers have used twisted, vortex beams to transmit data at 2.5 terabits per second, creating what's potentially the fastest communication technology ever developed. The twisted signals use orbital angular momentum (OAM) technology to deliver far more data within a single stream, an approach that could significantly expand the capacity of both landline and wireless networks in coming years
. In current technologies such as LTE, the technology only modulates the spin angular momentum (SAM) of radio waves, not the OAM -- while the twisted vortex beam approach modulates both. That's great news for an industry that claims it's in perpetual "spectrum crisis," as the technology could twist together an "infinite number" of existing transmission protocols without using any more spectrum
Gee... AT & T and Verizon won't like this at all. How else will they be able to hoard up every bit of available spectrum while squatting on so much of it already?
said by megarock:I doubt they will get excited. Research like this doesn't go into production for 10 yrs or more.

Distance? If they only performed the test over a distance of one meter, how long will it take to use the technology worldwide?
Re: Distance? Itsbry, you have to start somewhere. Now that they know they have something to work with, they can try and push it to do better.
Plus, who knows if it is even feasible out in real world conditions even after all that testing.
researchers Not surprising that this little discovery didn't come from one of the incumbent wireless providers making billions in the industry.
Useless for most current applications People seem to have missed two important facts here:
1) This was done with visible light, which means it's completely line-of-sight. A sheet of paper would block the signal.
2) This is a point-to-point beam, like a laser, not an omnidirectional broadcast like anything a consumer might care about.
This seems to have very narrow applications. Satellite broadcast, perhaps, or fixed wireless, but that's about it. It can never be used, as it stands now, for cellular service.

Re: Useless for most current applications OR over a fiber line
which is the use here
the idea is you can cram a STUPID amount of data in the fiber backbones so much for the Exaflood
the big issue is even slight changes in the earths gravity mess with it over distances of a few miles
so you ether need lots of repeaters or better hardware on the RX end to deal with it
More alien technology being used.... Nuff said !

Re: More alien technology I like how you think.
