\n

For a holiday park with approximately\u00a0200 chalets<\/b>\u00a0A transition from DOCSIS 3.0 to DOCSIS 3.1 is often worthwhile, but only if the rest of the infrastructure and the business case justify it. The biggest benefit lies not only in higher speeds, but also in more capacity and a better user experience when many guests are online at the same time.<\/span><\/i><\/p>\n<\/div>\n

\n

Here are the most important points:<\/i><\/p>\n<\/div>\n

\n

1. The current coaxial infrastructure<\/i><\/b><\/p>\n<\/div>\n

\n

First check whether the existing coaxial cable wiring is suitable.<\/i><\/p>\n<\/div>\n

\n

Think of:<\/i><\/p>\n<\/div>\n

    \n
  • quality and age of the coaxial cables;<\/li>\n
  • state of splitters, attenuators and amplifiers;<\/li>\n
  • level of interference (noise and glare);<\/li>\n
  • quality of connectors.<\/li>\n<\/ul>\n
    \n

    DOCSIS 3.1 uses higher modulations (up to 4096-QAM), which makes the network much \"cleaner\" than with DOCSIS 3.0.<\/i><\/p>\n<\/div>\n

    \n

    2. CMTS or CCAP<\/i><\/b><\/p>\n<\/div>\n

    \n

    The central equipment must support DOCSIS 3.1.<\/i><\/p>\n<\/div>\n

    \n

    That often means:<\/i><\/p>\n<\/div>\n

      \n
    • a software upgrade;<\/li>\n
    • new line cards;<\/li>\n
    • or a completely new CCAP solution.<\/li>\n<\/ul>\n
      \n

      This is usually the largest investment<\/i>, In addition to the network itself, all equipment and passive components must be suitable for the new signal that goes to higher frequencies.<\/i><\/p>\n<\/div>\n

      \n

      3. Cable modems<\/i><\/b><\/p>\n<\/div>\n

      \n

      All DOCSIS 3.0 modems will eventually have to be replaced by DOCSIS 3.1 modems.<\/i><\/p>\n<\/div>\n

      \n

      For 200 chalets, that means approximately:<\/i><\/p>\n<\/div>\n

        \n
      • 200 new modems;<\/li>\n
      • possibly modems with integrated WiFi 6 or WiFi 7.<\/li>\n<\/ul>\n
        \n

        Many operators combine both upgrades.<\/i>\u00a0Keep in mind that Docsis 3.1 modems are currently much more expensive to purchase than Docsis 3.0 modems. It only makes sense to offer Wifi 6 or even 7 if your guests' equipment also supports it!<\/i><\/p>\n<\/div>\n

        \n

        4. Bandwidth to the internet<\/i><\/b><\/p>\n<\/div>\n

        \n

        A DOCSIS 3.1 network is of little use when\u00a0<\/i>The total bandwidth of the park internet connection is too small.<\/i><\/p>\n<\/div>\n

        \n

        At 200 chalets\u00a0<\/i>In conjunction with Docsis 3.1, it is often thought of as:<\/i><\/p>\n<\/div>\n

          \n
        • At least 2 to 5 Gbit\/s internet capacity;<\/li>\n
        • Depending on:\n
            \n
          • streaming;<\/li>\n
          • IPTV;<\/li>\n
          • working from home;<\/li>\n
          • gaming.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

            With Docsis 3.0, the park often has enough bandwidth at 1 Gbit\/s.<\/p>\n

            \n

            5. Segmentation<\/i><\/b><\/p>\n<\/div>\n

            \n

            Often the network has grown historically.<\/i><\/p>\n<\/div>\n

            \n

            When upgrading, it may be a good idea to:<\/i><\/p>\n<\/div>\n

              \n
            • installing additional fiber optic cables to the neighborhood cabinets;<\/li>\n
            • make the coax segments smaller;<\/li>\n
            • connect fewer homes per segment.<\/li>\n<\/ul>\n
              \n

              That often yields more than just activating DOCSIS 3.1.<\/i>. Also if Docsis 3.0 remains in use<\/i><\/p>\n<\/div>\n

              \n

              6. Upstream<\/i><\/b><\/p>\n<\/div>\n

              \n

              A major advantage of DOCSIS 3.1 is the improved upload capacity.<\/i><\/p>\n<\/div>\n

              \n

              Steeds meer toepassingen vragen daarom:<\/i><\/p>\n<\/div>\n

                \n
              • videobellen;<\/li>\n
              • cloudopslag;<\/li>\n
              • beveiligingscamera's;<\/li>\n<\/ul>\n
                \n

                7. Toekomstbestendigheid<\/i><\/b><\/p>\n<\/div>\n

                \n

                DOCSIS 3.1 vormt een goede tussenstap richting:<\/i><\/p>\n<\/div>\n

                  \n
                • Full Duplex DOCSIS;<\/li>\n
                • DOCSIS 4.0 (als de hardware dat later ondersteunt).<\/li>\n<\/ul>\n
                  \n

                  Daardoor hoeft niet direct overal glasvezel naar elk chalet te worden aangelegd.<\/i><\/p>\n<\/div>\n

                  \n

                  Wanneer is het verstandig?<\/i><\/b><\/p>\n<\/div>\n

                  \n

                  Ja<\/i><\/b>, wanneer:<\/i><\/p>\n<\/div>\n

                    \n
                  • het coaxnet technisch in goede staat is;<\/li>\n
                  • de eigenaar de komende 5 tot 10 jaar op coax wil blijven;<\/li>\n
                  • gasten steeds hogere internetsnelheden verwachten;<\/li>\n
                  • het park veel streamingdiensten gebruikt;<\/li>\n
                  • thuiswerken vanaf het park een belangrijke doelgroep is.<\/li>\n<\/ul>\n
                    \n

                    Minder verstandig<\/i><\/b>, wanneer:<\/i><\/p>\n<\/div>\n

                      \n
                    • de coaxinstallatie oud en storingsgevoelig is\u00a0(alhoewel dit natuurlijk op te lossen is)<\/li>\n
                    • er toch al plannen zijn om glasvezel (FTTH) naar ieder chalet aan te leggen;\u00a0(Denk hierbij aan vervanging van andere ondergrondse infra zoals, riolering of waterleidingen)<\/li>\n
                    • de CMTS volledig vervangen moet worden \u00e9n de coax\u00a0onderdelen\u00a0grotendeels vernieuwd moet worden. In dat geval kan een volledige glasvezeloplossing economisch aantrekkelijker zijn.<\/li>\n<\/ul>\n
                      \n

                      Indicatieve capaciteit<\/i><\/b>\u00a0(maximaal toelaatbaar door de gebruikte techniek)<\/i><\/b><\/p>\n<\/div>\n
