Vortex wireless: Terabytes of Wi-Fi is on its way

Summary: You think 802.11n is fast with its up to 600Mbps , and you're looking forward to buying 802.11ac device with Gigabit speeds? Brace yourself, Terabyte Wi-Fi is on its way, and it won't interfere with any other near-by Wi-Fi transmission.

Vortex Wi-Fi is going to everything we thought we knew about wireless networking.

Vortex Wi-Fi is going to everything we thought we knew about wireless networking.

Wi-Fi networking has gotten to be remarkably fast. But even as 802.11n, with up to 600 Megabits per second (Mbps) speeds has become commonplace, and 802-11ac, with its Gigabit speeds is finally showing up, we've seen nothing like the speeds that the still experimental twisted, vortex beams using orbital angular momentum (OAM) is going to deliver. In the lab, OAM technologies is already delivering a mind-bending 2.5 Terabits per second (Tbps).

Alan Willner and fellow researchers from the University of Southern California, NASA’s Jet Propulsion Laboratory, and Tel Aviv University, have just announced in a Nature article, Terabit free-space data transmission employing orbital angular momentum multiplexing that they can deliver 2.56Tbps speeds with by twisting beams of light together, multiplexing them, and then encoding data using OAM and current Wi-Fi technologies, such as spin angular momentum (SAM), which we're already using in Wi-Fi and 4G.

How fast is that? 2.56Tbps is about the same as 320 Gigabytes (not bits, bytes) of data a second. Or, to put in more homey terms, as 25GBs for a typical single layer Blu-Ray HDTV movie, an OAM wireless connection could send almost 13 HDTV movies a second to your television.

In short by twisting wireless signals into spirals, the researchers were able to encode far more information into a single connection than we've ever seen with any other networking technology. Trie, this latest test was done with optical transmissions, over only a meter. Before that test though Bo Thide of the Swedish Institute of Space Physics has already proven that OAM can be used with conventional wireless technologies. In his tests, Thide was able to use 2.4GHz Wi-Fi signal to send an OAM encoded signal over 442 meters.

Thide maintains that is just the tip of the ice-berg. He believes that besides being able to drastically increase Wi-Fi network throughput that the use of “OAM states might dramatically increase the capacity of any frequency band, allowing the use of dense coding techniques in each of these new vortex radio channels.” In other with OAM vortexes we can potentially transmit an “infinite number of channels in a given, fixed bandwidth, even without using polarization, multiport or dense coding techniques” on any kind of wireless network--TV, radio, Wi-Fi, 4G, what have you--at the same time on the same frequency.

In short, not only could Vortex wireless vastly increase our wireless networking speed it could end all our current congested wireless network problems. As this technology moves from the lab bench to the home and office we will see a wireless networking transformation as great as any we've ever seen since Marconi and Tesla simultaneously invented radio in the 1890s.

No, I'm not kidding. Vortex wireless is going to change everything. and I mean everything, we thought we knew about the limits of wireless networking.

  • Capacity up by a quantum leap!

    Nice to know that someone is still working on increasing the speed of wireless networks. Of course, range, accuracy, encryption and all the other factors that make it useful need to be worked out along with the hardware aspects of the technology, but it will come, eventually!

  • Nice to know someone has discovered sub-space transmissions.

    Yes, I know this isn't Star trek technology but, my goodness, just think. In ten years perhaps a generation might grow up never having experienced something called "wires" or "cables". With this type of data transmission speed, that scenario could happen.

    • Cables will still exist...

      but mostly for "secured" networks. It's still far easier to hack a wireless network then a wired network.

      I still like where the technology is going though.

      • Good points! I had forgotten about the security angle.

        However, in ten years, perhaps quantum encryption techniques could be perfected that would render the security issue moot.

      • To intercept wirless pacets yes, but Wired is still vunrerable.

        An open ethernetport + malware infected Partner Company's Executive's Business/Personal laptop = Security breach.

  • Like ExxonMobile and cheap oil

    How resistive do you think data companies will be to THIS? Wireless bandwidth will have no value.

    • Exactly.

      We will never see this tech except in companies involved with the military industrial complex.
      kenosha77a
      • Sometimes, the military leads the way towards adoption and acceptance

        of new technology.

        If a company opts not to adopt a new technology, then some other will, or an entirely new one will.

        Technology keeps improving, and consumers keep wanting the newer and better and faster, and the private sector economy usually responds, if not soon, then later.

    • Based on this news Comcast has already sent out a rate increase :-)

      wouldn't expect anything else from Comcast.........

  • Interesting

    This probably makes those interested in user-maintained mobile mesh networks happy.

    But can storage media (or RAM) even send or receive data as quickly as this transmission method will transmit it? In other words, does it matter? At some point, this data has to get to a destination.

  • Fly in the ointment?

    The Nature Photonics article Terabits/sec was done with light. As the carrier frequency goes down so does the maximum data rate and number of "channels".

    Curious that there seems to be no mention of the data rate obtained with the 2.4GHz OAM "proof" test.

    • -1?

      Somebody doesn't like a dose of reality?
      wally_333
  • If this is using light...

    Then this is "line of sight" tech. Beats the pants off of current home wireless but would require line-of-sight relays to cover an entire house. I think most homeowners would balk at that, even if it is an unobtrusive as a small "puck" at intervals on the ceiling.

    • The article explicitly says

      That it's perfectly capable of being used with preexisting wireless technologies. The method doesn't care if it's a light wave or a radio wave.

  • Tesla Vortex?

    I'm just saying...
