      How will 21CN affect Sky Broadband?

      How will this new 21st century network affect Sky Broadband? Any guesses?

      How fast is it, If 21CN is say 24Mbps will Sky broadband again use LLU and up it 48Mbps or higher?

      Surely 21CN is more than 24Mbps, Be Broadband already does 24Mbps, with the use of fibre optic it could be 100Mbps + ?
      Although one particular country has 1Gbps broadband, I forget which, could be Japan or South Korea.

      Have Sky any plans of their own regarding broadband, perhaps via wireless means like satellite?

      I for one cannot wait for 21CN in 2010.

      Has anyone heard any rumours regarding this?

      ADSL2+ Cannot go higher than 24Mb as thats the limit of that technology the only way you can get 48Mb is with 2 lines bonded and that can be done now, What 21CN is that the telephone system will use the the new ADSL2+ DSLAMs for Broadband using VoIP doing away with the older analogue systems, personally I would have preferred FTTC using VDSL2+ in the cabinets or better still FTTP/H, but as you know BT are driven by profits (like any business) and have to answer to thier shareholders, so in a nutshell, it is highly unlikely FTTx will see light of day here in the UK

      Re: How will 21CN affect Sky Broadband?

      I think alot of people are getting confused, The 21CN doesnt effect the Broadband side of things unless you are on a BTw Resell plan, Like BT Broadband and any other who doesnt use LLU.

      This basicly means like stated, the PTSN (PSTN or PTSN, Never too sure) aka Phone System will be IPbased, and BTw will be reselling ADSL2+ instead of the DSLMax (upto 8Mb), The only people who will benefit most on the broadband side are those who are on Exchanges were the days of LLU havent started.

      Oh I thought it was suppose to reduce line attenuation so more people could get the full 24MB.

      Sounds a bit pointless really.

      I dont think it will, As the lines arent getting changed, Just the technology on the ends..? Correct me if im wrong!

      Sounds a bit pointless really.
      Thats what alot of people are saying, ADSL2+ is old'er now, When countries are rolling out VDSL2+ and FTTC/H and stuff!

      Re: How will 21CN affect Sky Broadband?

      From the wikipedia article

      The plan has come under some criticism, mainly due to BT's plans for high-speed internet services. BT's main plan for providing internet Access is placing ADSL2+ DSLAMs closer to customers premises by installing them in the street cabinets instead of the exchange.
      I have no idea what a DSLAM is but I assumed it meant having them in street corners lowered the attenuation.

      Re: How will 21CN affect Sky Broadband?

      I dont know how it would work, But im assuming that is BT only..? So only if you were on a BTw reseller plan you would benefit as I dont think LLU ISPs would install there equiptment in them..? or would they..?

      But that would be great, As an average home is around a few hundred metres from a cabinet which is better then a few kilometres.

      Re: How will 21CN affect Sky Broadband?

      What you described there is FTTC of which I think the Wikipedia article is wrong, what I believe it to be is ADSL2+ is replacing ADSLMax and analogue lines (PTSN) are being transferred to that technology for voice communications (VoIP)

      I could be wrong tho?
