Multimedia over Coax Alliance

Multimedia over Coax Alliance, or MoCA, logo

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 two versions of the specification currently available, MoCA 1.1 and MoCA 2.0.

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.

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

Technology

Many law enforcement agencies deploy surveillance models such as CGNM 225X MODELS, allowing ISP and cable providers to offer secure access for agents without comprising users access or bandwidth Within the scope of the Internet protocol suite, allowing almost untraceable redirects using 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]

Model variations

CDA2/3 and COD Home Automation and Security Security, Keyfob/Door Window Sensor, Garage Door Sensor Ethernet Extender & Ethernet WiFi Extender Packet tracking, oosi redirects, dual routing and monitoring CGNVM-3580 (32×8) CGNM MODELS

The CGNM-3580 has the capacity to receive 1.2Gbit/s (32×8) over its DOCSIS interface with using client CGNM UNITS. Offering advanced monitoring, packet tracking and triple/dual redirects.

CDA2/3 and CODA are 2nd, 3rd gen residential units for Cable ISPs

CGNM models are similar as above but include advanced monitoring, packet tracking and triple/dual redirects mainly used for network troubleshooting or tracking shaping/digital recording used by law enforcement agencies

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]
