What is MoCA
 

Truth in Networking
 

Setting Up A MoCA 2.0 Ethernet-Over-Coax Network, Linux LAN Benchmarks
By Michael Larabel in Peripherals 
"This was my first time dealing with MoCA adapters and it worked out well and actually exceeded my expectations. I have coax wiring in almost every room but it's gone unused except for one cable modem and then just making use of PlayStation Vue on my Fire TV Sticks / Roku devices for viewing on each of the TVs...

The Best Medium For Home Entertainment Networks Is Already In Your House!

“I just love this MoCA technology. I love that it just works. I use it in my 1971 townhome to connect the basement entry point (where I also have my office) to my 2nd floor entertainment center. HD streaming is so smooth with this MoCA. I also run my wireless Access Point from the 2nd floor outlet through the MoCA.

I love the fact that you can use MoCA wherever coax cable exists. I also love the fact that you can create a system with no wireless exposure to you in your home if you want because the coax cable confines the stray energy discharge to a minimum. This is important for people who are electrically sensitive to WiFi.”

Frequently Asked Questions

No. Daisy chaining MoCA devices (i.e. connecting one MoCA device through the TV Out port of another) is not recommended because the TV Out port filters out the MoCA signal.

Yes. A CATV amplifier can block or interfere with the MoCA signal and cause the MoCA bridge to malfunction. Avoid placing an amplifier in the path of the MoCA nodes unless it properly bypasses the MoCA frequencies (850 to 1525 MHz) or use a moCA-compatible amp.

The current MoCA cable products only work with cable TV, FiOS or off-air TV services. This is because the frequency band which the current MoCA products use, 850-1550 MHz will interfere with satellite TV signals (but don’t interfere with cable or off-air signals).

DirecTV has MoCA products designed specifically for their frequency band (<800 MHz). Therefore the DirecTV MoCA bridges will only work with DirecTV installations, unless you have a totally separate coax TV cable network for cable/off air. Another requirement is that the customer have a SWM (Single Wire Multi-Switch) install which is being put into all new HD households. DirecTV’s MoCA bridge is called DECA (DirecTV Ethernet-to-Coax Adapter) and is available from various online retailers.

DISH Network has MoCA products designed specifically for their frequency band too (<800 MHz). Hopper, Joey and Super Joey have built-in MoCA bridges that will only work with DISH installations, unless you have a totally separate coax TV cable network for cable/off air. Hopper and Joeys are connected with a series of coaxial cables. This is how they're able to communicate with each other, allowing any connected Joeys to access the DVR system stored on your Hopper thanks to MoCA and your coax TV cable.

MoCA products will work with Verizon FiOS and not interfere with the TV signal. If you have a Verizon FiOS set-top box and a MoCA adapter, use a splitter to separate the coax cable.

AT&T U-Verse is the only paid TV service in the United States that does not use MoCA, thus MoCA technology products will not work in this environment.

Installing a Point of Entry (POE) filter could possibly improve the performance of your MoCA home network.  The POE filter is installed at the cable point of entry to your home and keeps the MoCA signals from leaking out of your home’s cable system.  The filter actually reflects MoCA signals back in to your home coax which may boost your signal strength resulting in better performance.  Ask your product manufacturer about where to obtain a POE filter.  UPDATE: POE filters are available from Soontai or their distributor Power & Tel Supply.

If your MoCA bridge only has one port, you can connect it to an Ethernet switch with usually 5-ports or 8-ports to gain additional ports. Ethernet switches are inexpensive and available from most major home networking manufacturers.

Up to 16 MoCA devices can be on a network using MoCA 1.1.

Yes. If the TV is connected to the “Coax Out” port of the bridge, the TV picture can become worse when the bridge is powered off. The user can connect TV to an external splitter, instead of the “Coax Out” port, to resolve the issue.

To join an existing MoCA network, first install MoCA bridge normally to see if it connects automatically with no password. If it doesn’t connect, try resetting your MoCA bridges and then connecting them back-to-back to make sure they can connect separately from the MoCA network. If the bridges work properly and it still doesn’t connect to your network, contact your service provider for their MoCA network password and add it to bridge using the configuration utility. To date, none of the service providers have implemented a password for their network.

The amount of bandwidth needed to transfer HD video depends on the resolution of the video (e.g. 720p, 1080i, 1080p) and the size of the file.

720p – 6+ Mbps recommended

1080i – 8+ Mbps recommended

1080p – 10+ Mbps recommended

Wireless extenders from Actiontec are capable of 1Gbps.

Recommended maximum of 300 feet of cable between the root node and the coax outlet.

Yes, MoCA is a standard like Wi-Fi® so products from different manufacturers are tested. Only MoCA certified products are guaranteed to be interoperable.
