    • Alanh, I see that in another thread (a new thread) you have raised the subject matter of inadequate download speed for UHD video in Australia with fibre to the node, stating:  "Remember that UHD requires 25 Mbit/s, it is available to all those on glass fibre, however Fibre to the node speed reduces drastically as the distance from the node increases but also as the number of simultaneous subscribers and internet users will also slow it down."   I'd invite you again to please explain the basis of your claim in this old thread that the speed of fibre to the cabinet (i.e. node) in the UK averages 13Mbps. Your words posted in this thread on 28/6/2016 were: "The UK experience as measured by Ofcom which is their equivalent of the Department of Communications says that their average speed for fibre to the node is 13 Mbit/s."
    • I may be wrong but I'd have thought that if all premises in a particular district had a high maximum speed direct to the premises connection then the total demand for that district would tend to be higher as more people tried to use that maximum speed capability; all other things being equal.   My understanding is that the reported peak period bottlenecks for fibre to the node districts may have not been occurring in the last leg of the chain of distribution (i.e. from the node to a particular house) but by reason of limited maximum bandwidth made available to the various nodes in the district.  This reportedly can be due to particular ISPs not purchasing sufficient bandwidth for use by their subscribers. I have only a very broad knowledge in this subject area, but I've always assumed HFC in a particular street would use a single feeder with take-off points along the way (somewhat similar to how premises in a street connect to a water mains that runs down the street). That's presumably why HFC usage by one household competes with HFC usage by another household: they share a feeder cable.  And I've assumed fibre to the node involves direct copper cabling from each premises all the way to the cabinet for that node. (Perhaps a risk of some extent of induced currents between adjacent copper wires, but still separate wires.) Broadly analagous, it could be suggested, to each house having a separate small diameter water pipe running several blocks to a water mains.  I would presume that whichever topology is used for NBN distribution in a district there will be limits on the total bandwidth that the subscribers in that district can draw simultaneously.   As for how use by other people in a particular street would affect a given user in that street who is connected by copper cable to a node I don't know. Where can such practical detail be found?   *   *   * Alanh, no need for you to answer this post of mine.  However if you plan on making future comments about insufficiency of download speed for UHD for fibre to the node subscribers it might help to point to your source(s) of information. I am reminded that a few weeks ago in another thread  you claimed that the fibre to the cabinet speeds in the UK were very low but your claim was contradicted by evidence I looked for and then quoted from. You appear to have forgotten about that thread. Do not fear! I'll find that thread in a moment and reraise the matter there! Edit: The other thread is 2018 Commonwealth Games. See:

    • Remember that UHD requires 25 Mbit/s, it is available to all those on glass fibre, however Fibre to the node speed reduces drastically as the distance from the node increases but also as the number of simultaneous subscribers and internet users will also slow it down. The wide spread use of HFC cable for the NBN is yet to happen, How much will it slow down when there are the maximum number of simultaneous users? The proportion of the population which will be able to view UHD from the internet will not be as many as most would expect. DVB-S2 is currently being used with HEVC/HE-AAC by pay satellite providers in Europe. So in cable areas, their best option may be to replace the cable systems with either DVB-C2/HEVC/HE-AAC system including the cable STB or go satellite as they already use in Perth and country areas. The advantage of DVB-S2 and DVB-C(2) systems are that they are one way where as internet systems require bidirectional operation. Alanh
