Japanese scientists develop 20x faster Wi-Fi using T-rays

  1. A team of Japanese scientists have succeeded in breaking the record for wireless data transmission in the terahertz range. The researchers were able to achieve speeds that are 20 times...

    Read the whole story
  2. now they only need to get that speed over a range of 100meters.
  3. eventually, range will be improved. its jut nice to hear upcoming technologies that are already on the terahertz range..

    yeah, maybe... so far as I know (which isn't very far), the smaller the wavelength the less it can penetrate things. The bigger question is do we need it? I think current wi-fi is already fine for current needs. my wi-fi is faster than my internet. Although in 2020 when my TV has a resolution of 7680x4320 we may need the extra bandwidth. ;)

    Between microwave and infrared range. Not only can we get faster data transfer, but we can possibly cook anything between the two access points for dinner...

    Of course it's good for your HOME internet with which you connect a single computer over wireless connection TO THE internet.

    How about you think in big companies now, or server connections which require more data to backup or whatnot wirelessly to another computer on the private network.

    Wireless monitors FINALLY

    It's interesting to note that such a high radio frequency will have poor range.

    In open air, it might be 10 meters but when it comes to traveling through desks, walls and bookcases, I suspect it would be useless.

    Look no further existing airport scanners, medical scanners, infrared and UV light which may be able to travel through low density materials (plastics, cloth) but can't penetrate most types of tissue, liquids or metals.

    It could prove useful for line-of-sight connectivity though. The bandwidth boost from such a high frequency is undeniable... just pray no one walks in front of it.
  9. "anonymous scientists develop protocol bypassing ISP data cap"
    ...now that would be epic...
  10. can I use some contents of this article? I will create back link to this page as reference......................

    Yes. Welcome to the Internet.

    Someone mentioned wireless monitors, I suppose that would about be possible with this?
    that would be awesome.

    Cool! I'll hit my data cap in less than 2 minutes.

    I would be happy with even 10 meter range. In fact I would prefer it. No neighbor snooping or free riding onto your internet connection. I essentially use wifi only to keep my devices untethered !

    Assuming your actual internet speed is faster than, like, 5 MB a second

  17. IMHO wifi is not only about Internet. At work or even at home when transferring large files and chunks of data, a faster wifi connection will be helpful.

  18. That's funny there, I don't care who you are!
  19. I just got a mental picture of using tightbeam emitters to quickly bounce the wifi across the building, and then it bounces into an omnidirectional emitter, which puts out the signal across a cubicle block or something. You could mount the emitters near or on the ceiling to avoid getting stopped by walls.

    Might just be Science Fiction, but it's interesting.

    Similar work to what the Technical University of Denmark did last year in the W-band?

    I'm curious how either of the two technologies will look in the hands of a consumer.
