Multimedia over Coax Alliance

Multimedia over Coax Alliance (MoCA) is an industry standard alliance developing technology for the connected home. MoCA technology runs over the existing in-home and in-building 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.

MoCA has now entered the broadband access market targeting MDUs (Multidwelling Units).

MoCA was established in 2004.

MoCA 1.0 was approved in 2006, MoCA 1.1 in April 2010, MoCA 2.0 in June 2010, and MoCA 2.5 in April 2016.

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

Products integrating MoCA technology are found in the service-provider, custom-installer, and retail channels. Applications include:

The Alliance currently has 45 members including pay TV operators, OEMs, CE manufacturers and IC vendors.

Promoters (represented on the Board of Directors) include Arris, Broadcom, Comcast, Cox Communications, AT&T/DirecTV, Echostar, Intel, MaxLinear and Verizon.

Within the scope of the , 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.

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

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

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.
