German Cable ISP First To Deliver 4700Mbps Internet Connection 121

Mark.JUK writes "It's enough to make grown IT workers cry. German cable operator Kabel Deutschland claims to have become the first provider to successfully achieve a real-world internet connection speed of 4700Mbps (Megabits per second) after they hooked up to a local school's test account in the city of Schwerin. The ISP, which usually delivers more modest speeds of up to 100Mbps to home subscribers, used its upgraded 862MHz network, channel bonding, and the EuroDocsis 3.0 standard to achieve the stated performance. But don't expect to get this kind of speed tomorrow; right now there's no demand for it among home users, and you probably couldn't afford the bandwidth anyway."

    They used 12 modems and thus 12 seperate channels which means in reality, they only transmitted about 400mbit per "subscriber" (cable).

    While this is nifty, Kabel Deutschland subscribers' bandwith is often shared, which means at peak time you don't even get 30 of the promised 100mbit. In addition to that, they slow you down after a 10gb quota/day. And in addition to that, they often throttle certain protocols, namely torrent.

    This is one of the worst ISP in Germany who just made a totally useless world record.

      These 'ISP record' attempts are doubly pointless(in addition to the fact that they never indicate the slightest enthusiasm to actually offer something even approaching that speed, at any reasonable price, to any of their customers) because they typically are markedly slower than the already-standard high-speed interconnects that tie more central sites together.

      If you are going to play pure speed-racer games, it really makes more sense to just have a set of categories based on medium(eg. 1km legacy POTS copper, 1km legacy coax, 1km single-mode fiber, 10km of each, etc.) There are real engineering challenges, and nontrivial advances, in the ability to shove more data over a link of a given nastiness; but 'records' based on unrealistic location stunts are just pointless(Telco B could just pull some fiber to a convenient school tomorrow and pull off a 'first-to-deliver 10,000mbps internet connection! and Telco C could just pull a few more strands and deliver twice that, and so on).

      If you want to boast about how cool an ISP you are, you need speed, breadth, and price. If you want to boast about your super-sneaky transmission methods, just tell us about the medium, the distance, and the bitrate; but this nonsense is a pure stunt.
    • Unfortunately, this is true worldwide
      For example I pay 1399 INR for a 4mbps ADSL connection in India (25$ approx).
      However, monthly quota is 30GB, after which you get throttled to 256kbps

      Some countries have 200-300GB quotas as the norm, while people like us are at 30GB.

      The 20$ plan from the same ISP gives you around 10GB/month quota.
      I expect the problem to get worse in the future.

        Prices here in Norway:
        Uncapped 5 Mbps ADSL: Around $50
        Uncapped 60/60 fiber: Around $90

        Okay quite a bit more than you're paying but Norway is in general an extremely expensive country overall, an average full time salary is $75k so by our standards it's cheap. And I once downloaded a 500GB torrent, it really is uncapped. And this country has a population density of 13/km^2 as opposed to India with 368/km^2, delivering broadband there should be much much cheaper. I honestly wouldn't worry it seems mostly like

      Even if it had been one modem and line, being able to use multiple channels for downstream and upstream traffic was pretty much the point of DOCSIS 3.0. Assuming the network itself has the bandwidth, getting higher speeds is really just a matter of using more lanes - for 4700 Mbps down, I think that'd be around 90. It'd be cool and all, but raising the max bandwidth of a DOCSIS 3.0 device doesn't really take much other than network capacity and a modem that will use that many channels - channel bonding isn'

      subscribers' bandwith is often shared

      All ISPs are shared at some level. I'm assuming you mean the node bandwidth is shared/over-subscribed?

      They used 12 modems and thus 12 seperate channels

      Many modems can bond up to 8 virtual channels on the down stream. As far as we know, it could have been anywhere from 1-8 8mhz channels per modem. Even with a single 8mhz channel, DOCSIS3 can bond 8 virtual CDMA channels for a combined bandwidth of 8X50Mb/s=~400Mb/s (EuroDocsis). DOCSIS3 has no limitation on how many channels may be bonded, but I'm not sure of any modem that supports more than 8 right now.

      Still cheaper/simpler to use fiber, but cable can manage some crazy high speeds if you throw enough tech/money at it.

      Still better than what I am pulling down during peak times here in Wisconsin. I pay for 25 Mbit and the only time I ever seem to be able to get it is when I'm running Charter's speed test on their web site at the behest of the CS people when I call to complain (how convenient, am I right?). Any other time, my 25 Mbit connection tops out at 12, and that's off-peak. Between 5PM-9PM, I'm lucky to pull down 3 Mbit and usually have

      The last Charter tech that came out to my house (and I have them out at least once a year for service issues) told me to my face that my node was way over-saturated (due to the high volume of apartment communities in this area, there are 300 units in my complex alone and there are a dozen complexes along this street) but Charter doesn't upgrade their shit until enough people start dropping the service to make it worth their while. I guess QoS means jack shit to them...I know, surprise, surprise. Still, it's irritating because my only other choice is shit-tier DSL and from what other residents have told me, the phone lines in this building are piss-poor, too.

      God what I would give for some real competition in this area. I imagine our Charter issues would evaporate virtually overnight...

      • I lived in an apartment with shitty wiring, makes for some very frustrating DSL experience. Since I was at the perimeter of the complex and near the junction box the tech was able to work some voodoo magic and get my 3Mbps connection to work at at least 2...
        I have always wondered why an apartment wouldn't pay for a fast connection then resell to the residents (or use it as a perk). Mine had close to 300 units, they could have made a killing by just slightly undercutting DSL/Cable internet fees.

I moved... mostly because it was in New Jersey and living in Manhattan is so much cooler.

        I'm currently on a 200/10 Mbit/s cable connection. Previously it would max out at around 10.5Mbit/s pretty constantly, so I had set my QoS settings to regard that as the maximum upstream bitrate. Suddenly a few weeks ago I noticed the packet queue grew way out of size and started dropping packets. I kept raising the max bitrate until I reached 12

      17.4 seconds a day. you could use that magical connection for seventeen seconds a day.

      I don't get quota but 10gb a day and then slow is better than some.

      Personally it should be 2-3gb an hour and then slow for an hour. That will cut on torrents but still allow multiple streaming movies.

      Of course torrents can handle the slow downs.

    It brings a tear to my eye to see the "modest" and "100Mbit" used in the same sentence. Yes, I realize that compared to 4700Mbit it is but I just got upgraded to 5Mbit so I still think you're insensitive clods!

    And yeah, I'm sure I could find a use for 4700Mbit.

    I have a 200Mbps connection at home, and for now it's fine for, well, everything. But it's really hard to tell what kind of speeds will be useful in the future. Let's imagine a virtual tailor service... Assume that you could go online, image yourself with a high res 3D webcam, and order custom clothes, complete with a virtual mirror to try them on. I'm guessing my 200Mbps connection would fall short at that point.

    This is the kind of chicken and egg problem we have with broadband right now. The next generation of online services can't be profitable because the infrastructure isn't there, and at the same time there is "no demand" for really high speed connections, since there are no services that need them.

    But at least one can stay positive and hope for cool sci-fi tech, right? ;)

Take a few extra shots/some extra video in certain poses or with certain movements to determine rigging data. Send the data to the tailor.

    4700 Mbit/s = 4.7 Gbit/s, how's that a record? The Gathering here in Norway had a 200 Gbit/s Internet Connection, topping Dreamhack in Sweden's 120 Gbit/s. Maybe it's some silly 4.7 Gbit over cable, but that's like the wold's fastest subcompact. And for all of us that have fiber to the home, yeah we know it's just what equipment you put on both ends. The cable itself could probably pull 100 Gbit/s with the right equipment.

    • With the assumption that they are using single-mode fiber, you will cap out at roughly 40Gbps to the home. If it's multimode, you could pull 100, but the max lengths are so much shorter, I'm not sure that is what they are using. Also, I suspect that FTTH uses the same link aggregation that DSL uses.

        They've done 111 Gbps on a single channel in the lab, but yes "only" 40 Gbps is more likely but I can live with that. Normally I can reach 5-6 MB/s actual transfer rates on my 60 Mbps fiber so it can't be that oversubscribed, I suspect the backbone hookup is far more than a OC-12. I could get 400 Mbps for about $1000/month, 1000 Mbps is available at "call us" prices so it's technically possible to get something ridiculously fast already.
