Multimedia over Coax Alliance (MoCA) is an industry standard alliance developing technology for the connected home. MoCA technology runs over the existing in-home coaxial cabling, enabling whole-home distribution of high definition video and content.

There are three versions of the specification currently available, MoCA 1.1, MoCA 2.0, and MoCA 2.5.

Products

Products integrating MoCA technology are found in the service-provider, custom-installer, and retail channels.[1]

Applications:

History

MoCA was established in 2004.

MoCA 1.0 was approved in 2006.

MoCA 1.1 was approved in April 2010.

MoCA 2.0 was approved in June 2010.

MoCA 2.5 was approved in April 2016.

The Digital Living Network Alliance approved the MoCA technology specification for incorporation into its guidelines in 2009.[3]

Technology

Within the scope of the Internet protocol suite, MoCA is a protocol that provides the link layer. In the 7-layer OSI model, it would be part of the data link layer (layer 2). DLNA approved of MoCA as a layer 2 protocol.[4]

MoCA 1.1

MoCA 1.1 provides 175 Mbit/s net throughputs (275 Mbit/s PHY rate) and operates in the 500 to 1500 MHz frequency range.[5]

The Alliance publishes a list of certified products on their home page.[6]

MoCA 2.0

MoCA 2.0 supports two performance modes, Basic and Enhanced, with 400 Mbit/s and 800 Mbit/s net throughputs (MAC), using 700 Mbit/s and 1.4 Gbit/s PHY rates, respectively. Turbo Mode yields 1Gbit/s net throughput. Operating frequency range is 500 to 1650 MHz. Packet error rate is 1 packet error in 100 million.[7]

MoCA 2.0 also offers lower power modes of sleep and standby and is backward interoperable with MoCA 1.1.[8]

MoCA 2.5

MoCA 2.5 offers actual data rates up to 2.5 Gbps, continues to be backward interoperable with MoCA 2.0 and MoCA 1.1, and adds a variety of network management and security features.[9]

Notes:

  • Channel C4 is commonly used for Verizon FiOS for the "WAN" link from the ONT to the router.[11][12]
  • Channels D1-D8 are commonly used for "LAN" links, between set-top boxes and the router.[11][12]
  • E band channels are commonly used by DirecTV converter boxes.[13] The DirecTV Ethernet-to-Coax Adapter (DECA) uses MoCA on this "Mid-RF" frequency band.[14]
