Multimedia over Coax

The Multimedia over Coax Alliance (MoCA) is an international standards consortium publishing specifications for networking over coaxial cable.

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

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

MoCA’s board of directors consists of Arris, Broadcom, Comcast, Cox Communications, 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 provides definitions within the data link layer (layer 2) and the physical layer (layer 1). 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.

MoCA 2.0 offers actual throughputs (MAC rate) up to 1 Gbps. Operating frequency range is 500 to 1650 MHz. Packet error rate is 1 packet error in 100 million.

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

In March 2017, SCTE/ISBE society and MoCA consortium began creating a new "standards operational practice" (SCTE 235) to provide MoCA 2.0 with Docsis 3.1 interoperability. Interoperability is necessary because both MoCA 2.0 and Docsis 3.1 may operate in the frequency range above 1 GHz. The standard "addresses the need to prevent degradation or failure of signals due to a shared frequency range above 1 GHz".
