MoCA Home Network Setup (Ethernet over TV Cable)
 
Sharing my journey with setting up MoCA at my home - I hope it is useful to somebody. Please note the following is just my experience and not everything might be technically correct. Any feedback or addition is welcome - I'm always happy to learn!



##################################################################
#### STORY #########################################################
##################################################################

I recently switched from Starhub 100Mbps Cable Broadband to ViewQwest 2Gbps Fibre Broadband and with that change I also wanted to solve my annoying WiFi connectivity issues whilst using the actual bandwidth I'm paying for. The only way to get fast internet to my computer in a room that it furthest away from the fibre termination point in the living room was via wired connection.

Unfortunately, my building does not have Ethernet wiring and I'm not really interested in having any cable lying lose between rooms. I haven't made any good experience with PowerLine devices in the past (Ethernet over electrical wiring) and the only other thing I stumbled across was MoCA - which finally solved all my issues and gives me around 950Mbps internet access.

Here is my current setup at home with fibre internet provided by ViewQwest. Starhub is in the diagram as they used to provide me with cable internet and TV.

##################################################################
#### FUNDAMENTALS ###################################################
##################################################################

MoCA stands for 'Multimedia over Coax Alliance'. The technology behind that term allows the distribution of ethernet data over the existing in-home coaxial TV cabling. Simply said, it can convert a Ethernet signal to run over coaxial cables. MoCA networking can co-exist with video data on the same coax cable.

---ethernet-cable-----[MoCA Device]=====coax-cable=====[MoCA Device]-----ethernet-cable---

MoCA version 1.0 was approved in March 2006, MoCA 1.1 in April 2010, MoCA 2.0 in June 2010 and MoCA 2.5 in April 2016. Technical throughput specifications are:

• MoCA 1.0 ---> 100 Mbit/s
• MoCA 1.1 ---> 175 Mbit/s
• MoCA 2.0 ---> 500 Mbit/s
• MoCA 2.0 bonded ---> 1.0 Gbp/s
• MoCA 2.1 ---> 500 Mbit/s
• MoCA 2.1 bonded ---> 1.0 Gbp/s
• MoCA 2.5 ---> 2.5 Gbp/s

MoCA uses frequencies between 500MHz to 1650MHz (dependent on the application). Cable companies typically use frequencies up to 1000MHz to send signals, satellite dishes usually use frequencies above 1000MHz.




##################################################################
#### POE FILTER ######################################################
##################################################################

In order for MoCA to work, a 'Point Of Entry Filter' needs to be installed into the main coax cable before it branches off into different coax outlets of your flat. The cable connection can be found at an entry point into your premises such as a riser cabinet or a cable distribution box within your home.

The filter simply blocks MoCA frequencies going back into your cable providers network (or your neighbours network) and potentially interfering with the network or system elements.

Alternatively, the incoming main coax cable can also be disconnected from your home network if no service is used by the cable provider (just ensure to add a 75 Ohm terminator cap to your coax splitter).

Either ways - one solution is mandatory! For me, Starhub installed the POE filter in the riser cabinet free of cost - the filter used is a 'Soontai LPF-1002M3'.

##################################################################
#### COAX SPLITTER ###################################################
##################################################################

Depending on your home network you may have more than one coax cable outlet. If so, it is most likely that a 'coax splitter' is used. A coax splitter has one input where the provider signal enters the splitter and at least two outputs where the signal leaves the splitter to go to devices. If multiple devices are using the splitter, the signal for each device will be weaker than if the signal went straight to a single device without running through the splitter. The more times the signal is split the weaker it will become.

‖ ‖ ‖
‖ ‖ +======> [Coax Outlet] Bedroom Master
‖ ‖
‖ +=========> [Coax Outlet] Bedroom Large Common

+============> [Coax Outlet] Bedroom Small Common


Most coax splitter have a frequency band filter built in and a label on the splitter indicating the frequency band (for example '5-1000 Mhz'). This means, that the splitter blocks any frequencies outside of this range in any direction. Whilst MoCA operates some frequency bands above this range it should not affect the performance in any meaningful way.

If you happen to encounter issues you can try to replace the coax splitter with another frequency band model such as '5-1500 Mhz' or '5-1750 Mhz'. Another issue might be that the coax splitter in use is extremely old and has ferite cores instead of an integrated circuits. In any case, you can find modern replacement splitters in Sim Lim Square #03-69 at 'UF Technology'.

##################################################################
#### CONNECTIVITY ####################################################
##################################################################

I used RG-6 coax cables and Ethernet CAT6 cables for my home network in order to minimise any potential cabeling issues. Bespoke length RG-6 cables can be ordered in Sim Lim Tower #02-25 at 'LHS Electronics Enterprise' and I found decent quality Ethernet CAT6 cables in Sim Lim Square #04-01 at 'Cybermind'. I also tried to avoid any additional connectors (such as 90° F-type connectors) on my coax cables.





##################################################################
#### MOCA DEVICES ####################################################
##################################################################

According to my research in August 2017, the most recommended and discussed MoCA device on the internet is the 'Actiontec ECB6200 Bonded MoCA 2.0' which promises speeds up to 1Gbps. I ordered directly from Amazon Prime in the first days of the Singapore launch and the package arrived a few hours later. It includes the following:

• 2x Actiontec ECB6200 MoCA devices (120 x 65 x 26 mm)
• 2x AC Adapter (ADP #WA-10P05FU, US Plug Type A 100-240V, 1.3mm connector 5V DC/2A)
• 2x RG6 coax cable (Male F connectors, black, 50cm)
• 2x CAT5E ethernet cable (RJ45 connectors, yellow, 100cm)
• 1x Starburst Technologies 2-way coaxial splitter (5-1675Mhz)

Replacement AC adaptor devices with a UK Plug Type G for Singapore can be bought in Sim Lim Tower #01-05 at 'Ask Electronic' or at #B1-36B at 'IDO Technologies' but the easier solution is just to use a fused adapter.

I personally do not recommend any of the advertised DirectTV devices. First, the power adapter is built with an US plug and ONLY operates at 120 Volts. Second, the devices can not co-exist with any video signal as they operate on the same frequency as your TV signal. And in my tests the internet transfer speeds I reached were at maximum ~65Mbps.

##################################################################
#### ECB6200 WEBINTERFACE #############################################
##################################################################

Whilst the Actiontec ECB6200 is a 'plug-and-play' device that doest not require any setup it still can be accessed via a web interface in order to gather more device information. Here are the steps:

• Unplug all cables connected to the Actiontec ECB6200
• Connect the ECB6200 to power and ensure that the 'Power' LED lights up
• Connect your computer via Ethernet cable to the ECB6200
• Set your computers Ethernet IP address to 192.168.144.10
• Set your computers gateway IP address to 192.168.144.1
• Start a browser and open 192.168.144.30

The interface is quite minimalistic with no real configuration options. Here are my default device details for the curious:

Device Info
• Board ID: 6802ECB
• SW Version: 2.11.1.50.6200.7
• RF Channel: 1150
• Band: Band D Extended

Configuration
• MoCA Password: xxxxxx
• MoCA Privacy: Disable
• RF Channel: 1150
• RF Band: Band D Extended
• RF Switch: Hi

Another tip: 1150 MHz is the default frequency in order to reduce attenuation.

If attenuation is not an issue, U can increase your frequency to to somewhere 1400 - 1500 to hit the close to the designed throughput.

Great info! Thanks!

Nice info there.......

Thought for small local area, all went the usual cat5e. Only for those that need distance and usually point to point use the coax. Which cost more.

because the infrastructure is already set up and it is not utilised: most of us are either watching local channels through the miotv/starhub/m1 set-top boxes or receiving the channels through the free-to-air antennae so you may use these sockets on the wall faceplates to transmit data instead. and the devices to do so are relatively cheap, less than us$20 :D

actually quite a few of us are using the directtv devices already and with no problems at all. and most of all, it is cheap: less than $20 :D

at this moment i am using the directtv device to connect to my computer to write this :D

coolvt2001 23-08-2017 07:34 PM

Appreciate if you can let us know the setup cost.

It is not about DirectTV, it's about MoCA - terry1 here is just rude and hijacking threads trying to sell his crappy product.

I am not clear about this setup,

1. do I need POE Filter?

2. the internet entry is in living room, if i want to have ethernet access in all of the other 3 rooms, do I have to
2.1. place a 1-to-4 splitter in living room coax point
2.2. connect living room Starhub set-top box to one of output
2.3. connect 3 MoCA adaptors to the other 3 output, then connect to Router's GE ports

3. In other rooms, connect MoCA adaptor in each Coax outlet, if that room also has set-top box, additional splitter is required too.

So I need at least
6 Adaptor (3 in living room, 3 in other rooms)
1 1-to-4 splitter
1 1-to-2 splitter
since each adaptor requires power, i need 6 wall plug slots too.

Is my understanding correct?

I am wondering, how the ethernet in guest room links to splitter output 2/GE 2, ethernet in study room links to splitter output 3/Router GE 3?

Will Starhub TV programs be affected when high volume data transfer happens?

Thanks

Ur tv pts shld b interconnected thru splitters already. The basic concept is 1 moca at router there 2 inject data into coax cables n at each location where u need 2 extract data u need 1 moca. Each moca is a transceiver. So typically if u want every room in a 3rm aptment 2 haf data thru coax u’ll need 4 moca. A pair is the minimum setup. U can DL moca user manual 2 understand the system better b4 buying. The POE filter is to prevent the data signal going out of ur hse. In smallnetbuilder forum the moca 2.0 bonded seems 2 haf good reviews wif some use reporting close 2 1gbps speed, which is impressive. Hope this helps.

Ok I got it, so it is like home plug, one coax in, other coax out, no need to allocate dedicated GE port for each room.

The adapter itself already splits to TV and Data so no need splitter too.

Questions:

Is starhub HD tv signal still good?

Since all data exchange happen on the same coax cable, if all rooms have heavy network connectivity at the same time like master room watching video on phone, guest room playing game, study room downloading, living room watching video on Apple TV. Will all of them still get good speed?

Is POE filter must? Where can I get it locally?

Starhub Cable HD Set top box required cable coaxial point.

As if you do this method then you may have to consider Starhub IPTV instead, unless you are not on Starhub Fibre.

Also don't forget that if this coaxial connection are old then there is possibility of signal loss.
That is due to the fact the wiring cables are hidden and may & could be wear out after years.
Should there is a failure within the cables inside, then the result is nil.
As this require that all the cables are good and reliable.
