Multimedia over Coax Alliance


The Multimedia over Coax Alliance 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.

History

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.

Membership

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, InCoax, MaxLinear and Verizon.

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 provides definitions within the data link layer and the physical layer. DLNA approved of MoCA as a layer 2 protocol.

MoCA 1.1

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

MoCA 2.0

MoCA 2.0 offers actual throughputs 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" 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".

MoCA 2.5

MoCA 2.5 offers actual data rates up to 2.5 Gbit/s, continues to be backward interoperable with MoCA 2.0 and MoCA 1.1, and adds MoCA protected setup, Management Proxy, Enhanced Privacy, Network wide Beacon Power, and Bridge detection.
MoCA Access is intended for multiple dwelling units such as hotels, resorts, hospitals, or educational facilities. It is based on the current MoCA 2.0 standard which is capable of 1 Gbps net throughputs, and MoCA 2.5 which is capable of 2.5 Gbps.

MoCA 3.0

The MoCA 3.0 standard is currently in development and is expected to increase the maximum throughput to 10 Gbps.
