You Say MoCA, I Say DECA – Which Is It?
If anyone is slightly confused about the differences between MoCA and DECA, they may sound like they’re different but in reality they are the same standard. MoCA stands for Multimedia over Coax Alliance which maintains the standards for MoCA coax networking. MoCA has specified 2 frequency bands at which the network can be operated: High-RF MoCA for Cable MSOs and Verizon FiOS from 850-1500 MHz, and Mid-RF MoCA for DirecTV from 500-850 MHz. Our more advanced readers may recognize that cable TV broadcasts below 850 MHz on the coax and satellite TV broadcasts above 950 MHz, hence the need for MoCA to avoid interfering with current signals on the line and 2 separate RF bands. Both versions of MoCA are being deployed primarily to enable the Multi-Room DVR feature available from all the major Pay TV providers.
So what is DECA? DECA stands for DirecTV Ethernet-to-Coax Adapter, a simple network bridge with an Ethernet port on one side and coax on the other, and operates at Mid-RF MoCA frequencies. The DECA is used mainly to connect legacy (older) DirecTV DVRs to Whole Home DVR service but is also being used by some consumers to connect Xbox’s, Bluray Players, Internet TVs, etc… to the Internet (also requires a DECA at the broadband router). Some folks are incorrectly using the term DECA to mean Mid-RF MoCA (which is technically incorrect, but perfectly understandable since it SOUNDS like MoCA).
The DECA’s counterpart for High-RF is called the MoCA ECB which stands for Ethernet-To-Coax Bridge. The ECB serves the same function for Cable MSOs and Verizon FiOS as a way to allow Ethernet onto the coax cable. One of the advantages of an ECB is that the same ECB, currently available from NETGEAR, D-LINK, or Actiontec, can be used with any Cable TV or Verizon FiOS service. Today, DECAs only work in DirecTV households and are not compatible with ECBs.
In summary, Cable and FiOS use High-RF MoCA which supports ECBs to convert between Ethernet and coax. DirecTV uses Mid-RF MoCA which supports DECAs to convert between Ethernet and coax. When will we have a single Ethernet-to-Coax bridge that is compatible with all MoCA bands? What will DISH Network use? Stay tuned to MoCABlog.net for the latest MoCA networking news and information.
Coax Home Nets Could See Five-Fold Rise by 2011
U.S. cable TV providers are expected to roll out multi-room DVR packages later this year based on the MoCA home networking technology. The services let TVs in various rooms link to a single DVR. To date Verizon has led the charge for MoCA, deploying MoCA as part of its FiOS broadband service. Time Warner, Cox, Brighthouse and Comcast, are likely to drive opportunities for MoCA in 2010 with the market moving from two million units per quarter towards up to 8 to 10 million units per quarter by the end of 2011, according to a report from Barclays Capital. MoCA’s next generation technology, MoCA 2.0 will be the next generation of MoCA. It will support two modes, one with throughput up to 400 Mbits/s and another with useable throughput up to 800 Mbits/s and is backward compatible with the current version 1.1.

MoCA Envy from Across the Pond
Here’s a great overview of MoCA and it’s applications from “The Mobile PC Doctor” from the UK. Although retail MoCA bridges haven’t yet made it to Britain’s shores, it’s good to know the word about MoCA coax networking is getting out there.
