Japanese Firms Claim 170Mb/s Service Via Powerline

Posted by ryuzaki0 on from the bits-that-go-fast dept.

valdean writes "Sony, Mitsubishi, and Panasonic have created and launched a new technology to transport Internet and media signals around the home via the electricity network at speeds 3x that of Wi-Fi. It's even fast enough for HDTV. The introduction is only dependent on government authorization."

    We have better. It's called GB lan. It's probably cheaper too.

    Asked why the three companies came up with their own technology and risked yet another format war in the consumer electronics world, Chmielewski said: "We think our technology is better."

    Translation: We patented our version. Ka-ching!

    Electrical power lines are not surrounded by a ground shield. I hope they came up with some security to go along with their high-frequency data mover.

      I think the outright devestation of several key radio bands will likely make this a non-starter in most other industrialized countries. If the Japanese wish to wipe out AM bands as well as emergency frequencies let them, but I doubt we'll ever see it in North America.

    From what I've learned, Japanese engineers have the enviable ability to invent something to fit their needs, even though the development cost would have to be recouped in sales. The stories I hear about developers here in America tell tales of requirements of immediate or near-immediate profits. *coughCarlyFionacough*

    i think your refering to the speed of the connection to the net, where as the article is (i think) refering to home networks, the slashdot post makes it look like it applies to total net connection though, i doube this works past the transformer comming into your home at that speed, if at all!

    If they implement this here, kiss your 2 way radio's good-bye. The radio interference those large powerlines give off when they are all jacked up with Broadband is nasty.

  7. Important Distinction by ErichTheWebGuy · · Score: 4, Insightful

    It is important to note that this technology would only work inside your home. It would never make it past the transformer at that speed, if even at all. Transformers, by their very nature, kill off any signal that would be sent down the line. Now if you could have a bypass, with a rather large resistor to cut back the outside voltage, then we might have something. Since that's not very practical, don't hold your breath.

    For home networks that wanna, say, stream HDTV from a media server with something like MythTV, that sounds pretty sweet.
