I’ve got a new build in the UK. Rather annoyingly there is standard UK Aerial cable to various places in the house but not ethernet. This is stapled to the stud work so I can’t use it to pull ethernet through.

Enter moca (I think)…

Each of the terminals has a separate line that all converge under the stairs (imagine a star-network topology).

Got a couple of questions:

  1. I have a particular device that does not use much network < 1MB per day and doesn’t require “high speed”. Given this is an entirely separate line, am I ok use a cheaper, passive, 10/100 Moca 1 device here or are these fraught with problems?
  2. For the other devices, I want as high speed/low ping as possible so will be using Moca 2.5. My question is, compared to ethernet, what am I not getting/what will be worse? (I was unable to get this answer from Google strangely - it just says its nearly-comparable to ethernet, but doesn’t tell me what nearly means)

    1. It’s cheaper, much, much, much cheaper. ~£15/pair vs. £130/pair.
    2. Glad I asked these questions as I’m definitely missing a trick here. If I have 2 devices that I wish to connect to my network. 2 coax cables and 4 Moca devices (1 for each end of the coax), plugged into switch - how do these form a a ring network?
    3. Presumably the conversion from signal to digital is the difference between Moca and Ethernet - is there a ping penalty to pay?

      I missed answering question #2. So the Ring Topology happens when you have 1 MoCA adapter connected to the switch, then to a splitter, then all coax connected to that splitter, then to the corresponding MoCA adapter (nodes). This saves you money as you will need less MoCA adapters (i.e., for 2 nodes, you only need 3; for 3 nodes, you only need 4).

      What you are planning to do is to use it as an ethernet alternative, which will be a 1:1 ethernet replacement. That will be expensive indeed, but will give you dedicated lines per node/device. If both MoCA adapters in the line are MoCA 2.5, then you have the full 2.5 gbps bandwidth at your disposal, if the device has a 2.5 NIC and your switch has 2.5 ports.

        Ah ok - I wasn’t planning on using a splitter, I would just going to stick a device on each end.

        So given this, it does make sense to go for the cheaper option as listed in [1] for one of the devices that doesn’t need the bandwidth - right?

        15ms ping is quite high isn’t it? Unless what you are quoting is to an external server over internet.
