New Look at ADSL2

Posted by ryuzaki0 on from the getting-connected dept.

genrader writes "broadbandreports.com just posted a news article which had an interesting story about the new ADSL2, which should be approved in 2003. They say it should be backward compatible with current hardware. It seems pretty interesting. ISP-Planet has the featured in-depth look at it, so you might want to see if it is of any intrest to you."

  1. Something Screwy by wirefarm · · Score: 4, Interesting

    I just signed up for a 12Mbit line here in Tokyo.
    (I'm upgrading from 8Mbit - the 12 is actually a cheaper plan.)

    Regular DSL, IIRC. Used the 30 year old wiring in my place, no problem.

    Even on the 8, I've had Internet downloads stream in at better than 1500K.

    A year or two ago, Japan was *way* behind in internet access - I was using ISDN (cheap here) and I was a bit of a rare case. Most people used dialup.

    So what's really holding DSL back over there? I'd bet the reasons were more economic than engineering.

    Just a thought,
    Jim

  2. New Paradigm by DrLudicrous · · Score: 4, Interesting
    The message board on dslreports.com didn't seem to high on this, and neither do we. Not suprising, I supposed, but do think about this: it's a baby step. You all are looking for some brand spanking new paradigm in broadband technology. That is not going to happen overnight, at least not in the forseeable future.

    I mean honestly, I am sure that someone here can explain why DSL is fundamentally going to be limited as far as bandwidth and range goes. Copper is a very lossy media, and we already have better stuff out there like fiber optic, and even fiberless communications versus mutliplexed wavelengths (eg Lucent) or even things such as wireless LAN's (although with a more limited range).

    The point is that what we need is something that is a complete departure from the paradigm of cable and DSL modems. That is the only thing that is going to allow us to ALL have broadband, and for the cheap, at very high speeds. I have no idea what it will be, though I think it will have to be some wireless technology. Until then, I think we are going to be stuck in this rut of a small number of broadband users who get to use a flawed and unsatisfactory system (except for those that just surf and check e-mail) due to speed constraints and whatnot.

    Any ideas of a new system, or how long one might take to engineer? I'm guessing around 20-35 years.
