How would you ever get 1Gb/s over a copper last mile?
- def_true_false 6y agoThe last mile in FTTC is more like the last few meters.
- pedrocr 6y agoSure, but VSDL will still top out at 300/100 Mb/s even over short distances: https://en.wikipedia.org/wiki/VDSL https://en.wikipedia.org/wiki/VDSL But apparently there is indeed a new standard for Gbit DSL up to 100m: https://en.wikipedia.org/wiki/G.fast https://en.wikipedia.org/wiki/G.fast
- znpy 6y agoYou don't of course, because you mostly can't. Yeah there might be some kind of technology to push the speed to that limit, but I don't expect to see speed pushed in the kind of areas where houses are sold basically at loss for 1€. So, long story short: that's the advertised speed.
- pedrocr 6y agoAdvertised speed usually means it's technically possible, even if it doesn't happen in practice. It seems there is indeed 1Gb/s VSDL technology but at least Wikipedia doesn't list any such deployment in Italy. But even 100Mb/s is good enough connectivity in my experience with fiber and apparently that's common for FTTC deployments.
- icebraining 6y agoMight not be DSL, but DOCSIS (coaxial), as part of an HFC system[1]. Version 3.1 can reach over 1Gbps, though that rather depends on how many people you are sharing it with. [1] https://en.wikipedia.org/wiki/Hybrid_fiber-coaxial https://en.wikipedia.org/wiki/Hybrid_fiber-coaxial
- kockic 6y agoMaybe starlink?
- znpy 6y agoStarlink is not live for general usage yet.
