Re: CODA-4582 MoCA 2.0 setup

Thanks @Datalink for the quick reply.  I was away and couldn't respond until now.  I read those posts previously before posting here... great detail and I learned quite a bit... but I'm still left with some unanswered questions and look forward to your input.

 

To answer some of your questions:

- I do use Nextbox Home PVR capability

- The house is wired with RG-6 (~15-20 year old house)

- no luck on the structured wiring... only has one RG-6 behind the wallplate.

- there is Cat5e cable on the opposite side of the room that was wired up for a phone line (which I don't use as I have VoIP and only leverage 2 RJ11 ports (1 for the VoIP adapter, 1 for the main phone... other phones connect to the main over bluetooth I presume).

 

My alarm system uses the VoIP house line which is about the only reason we have VoIP to being with... still a lot cheaper at ~$3 per month compared to using a non-phone line option for our alarm which would cost $10 per month.

 

Given the above, what would you recommend?

- if I go MoCA, do I need 1 adapter or 2?  Any recommendation on which adapter(s) to use?

- should I instead use the Cat5e cable?  my only concern here is the location of the cable... it's on an exterior wall and I fear it may be a challenge to get to through the attic and the sloped roof at that location.

 

Ultimately, I'd like the modem, router and switch in the basement with the wifi access point ceiling mounted on the 2nd floor while maximizing my gigabit connection (hence not sure if the Cat5e is ideal even though I have read that it may be able to handle it).

Just following up to see if anyone can help with these questions. Thanks

1.  My personal opinion is to go with two MoCA adapters, such as the Adaptec ECB6200 or goCoax WF-803M

 

https://www.actiontec.com/products/ecb6200/

https://www.gocoax.com/products

 

The modem does have a MoCA port on it with a claimed throughput rate of 800 Mb/s.  How well it works, don't know.  In any event, if you bought one adapter, you could try the modem as other half of the MoCA bridge to see how well it works and consider buying another adapter if you weren't satisfied with its performance.  And then again, it might be just as easy to buy a pair of adapters up front.  Food for thought.....

 

2.  Do you have telephone ports available throughout the house, that you're not using?  If so, are they fed with Cat-5 or Cat-3 cabling?  If they are Cat-5 you could probably repurpose them to ethernet cable ports.

 

3.  How is the upstairs ceiling access point connected and where is the other end of the feed cable?  I'm assuming that there is a POE adapter somewhere in the cable system.

Re: CODA-4582 MoCA 2.0 setup

Thanks again @Datalink. I think I'll wait for the gocoax to come back in stock. On paper, they look better and are cheaper as well

Unfortunately phone port line cat 5 is not an option for me.

As for the AP, I have a PoE injector that came with the AP that I plan on using.

Re: CODA-4582 MoCA 2.0 setup

Gocoax are finally back in stock. I ordered yesterday and have a friend in the US bringing them back for me mid-March.

Looking forward to getting my home setup and will report back once I have received the devices.

@Datalink - re-reading through your previous posts, once I move the modem to the basement, I should be able to remove the 2 way splitter in the family room as I'll only have one Netbox there thereafter. As such, I assume I'll only need one 3 or 4 way splitter in the basement that can handle MOCA. Is that right? Gocoax came out with a splitter (https://www.gocoax.com/product-page/ot-dsp-4). Any thoughts on that or would you recommend something else?

Re: CODA-4582 MoCA 2.0 setup

@rmann2020 in either case you're going to need a MoCa filter on the cable that arrives in the house from the external demarcation point.  Neither of those splitters have built in MoCA filters. 

 

The first choice looks like a satellite dish splitter, possibly used to connect a receiver to a multi-LNB dish, so it has higher frequency specs, above MoCA 2.0/2.5 specs of 1675 Mhz, along with lower loss specs.  The only drawback is the bottom frequency of 10 Mhz versus 5 Mhz that the current Antronix splitters have.  I don't think that's a major impediment as I can't see Rogers running upstream channels as low as 10 Mhz due to potential noise problems.  My upstream channels are currently running in the 30 to 34 Mhz range.  Over the last 6 years that has gone as low as 23.7 Mhz.   

 

The second choice is a new splitter that Antronix brought out a few short months ago.  The frequency range is set to match the MoCA 2.0/2.5 frequency range and runs from 5 to 1675 Mhz. 

 

Either splitter works, but the first one has a higher frequency range and lower losses.  If buying either one is equally easy or hard to order, I'd probably go with the first choice.

 

Something to keep in mind, Rogers is getting ready to extent the upper frequency range in the cable system, up to 1218 Mhz, where the lower MoCa D band frequency is 1125 Mhz.  So, there is a potential for overlap between a DOCSIS 3.1 OFDM band and a MoCA D-Low band channel.  But, its probably going to take month, years, maybe never(??) until Rogers enables an OFDM channel above 1002 Mhz, which is the current upper cable system limit.  So, when that happens, MoCA users may have to lock out the MoCA D-Low band on their adapters.  So, that will cost some amount of bandwidth on the MoCA system.  

 

Food for thought, if you happen to have structured wiring installed which has a pair of RG-6 cables running to each room, you can use one RG-6 cable for cable / satellite tv purposes and use the other cable for an internal MoCA (ethernet) system.  As long as that internal system is never connected to the external cable system, there wouldn't be any need for the MoCA filter.  Usually in a structured wiring bundle, you might find one black jacketed RG-6 cable and one white jacketed RG-6.   I would expect that if you happened to have structured wiring installed, that would also contain a Cat-5e or Cat-6 ethernet cable.   If you haven't checked behind your current wallplates, it might be worth having a look, just to see if there are any unused cables behind the wallplate.

Re: CODA-4582 MoCA 2.0 setup

@Datalink - thanks again for your guidance. I shared a photo of the currently installed MoCa filter from Rogers previously (message 39 on page 4 https://communityforums.rogers.com/t5/Internet/CODA-4582-MoCA-2-0-setup/m-p/451110#M57983) . Will that one work or should I go with a different option? Gocoax has released a filter (https://www.gocoax.com/product-page/ot-lpf-1002) but I have no idea if that is a good option either (I'm a complete newbie in this space). Given that you recommended the gocoax splitter, I will be purchasing from them again shortly regardless. One note on the splitter Reco, I only need a 3 way splitter... Is there any negative impact of using the 4 way you recommended? Would you go with a different option than the ones I shared?

Unfortunately I don't have structured wiring as that would have made things much simpler.

Re: CODA-4582 MoCA 2.0 setup

Hi @rmann2020 

 

For the splitter, if you bought the first splitter, you should install a 75 ohm terminator on the unused port to prevent any reflection off of the unused port.  If you were ever thinking of possibly adding another cable line to the MoCA network, that would give you some flexibility down the road. 

 

If you were to simply purchase the Antronix MoCA splitter with three output ports, that would be fine and you don't have to find a 75 ohm terminator. 

 

The MoCA filter that you referenced is a PPC 344 filter, shown here:

 

 https://www.amazon.ca/Filter-MoCA-Cable-coaxial-networks/dp/B00KO5KHSQ

 

Rogers uses Antronix MoCA filters shown here:

 

https://www.antronix.com/products/filters.aspx

 

Those filters are available in a higher MoCA band rejection than the PPC filter shows, but, I don't know which particular Antronix filter is used by Rogers.  If you happen to see a Rogers tech while you're enroute to somewhere, stop and ask if you can scrounge a MoCA 2.0 splitter and a MoCA filter from him.  If the tech happens to have those on hand, that might save you a few dollars.  You want to ensure that the MoCA 2.0 splitter is the correct splitter with the yellow face and a 5 to 1675 Mhz frequency range.

Re: CODA-4582 MoCA 2.0 setup

Turns out I needed Rogers to visit my house as my whole home PVR wasn't working. Unfortunately, the technician didn't have any of the yellow labelled splitters.

Interestingly, he removed the existing MoCa filter and said it's not needed anymore stating that Rogers doesn't use MoCa for whole home anymore.

@Datalink - in your opinion, was the technician correct? Should I re-install the MoCa filter?

I do plan on purchasing the Antronix 3 way splitter as I assume that is still needed.
