Multimedia over Coax Alliance
Multimedia over Coax Alliance (MoCA) is a trade group promoting a standard that uses coaxial cables to connect consumer electronics and home networking devices in homes. It allows both data communication and the transfer of audio and video streams.
History
MoCA was established in 2004. The MoCA MAC/PHY v1.0 specification was approved in February 2006. MoCA also completed its first certification wave in February 2006, ensuring interoperability between devices.
As of July 2011 the alliance had 10 promoters, 8 contributors, and many associate and affiliate members. Members include Actiontec, Advanced Digital Broadcast, Alcatel-Lucent, ARRIS, AT&T, Broadcom, Broadlight, CiscoSA, Comcast, Conexant, Cox Communications, DirecTV, EchoStar, Entropic, Freescale, Infineon, Intel, LG, Linksys, Motorola, Netgear, Pace, Panasonic, Pulse Engineering, Samsung, Sigma Designs SPIRENT Communications, STMicro, Tellabs, Texas Instruments, Time Warner Cable, Westell, Verizon, ViXS Systems and 2Wire.
The Digital Living Network Alliance approved the MoCA technology standard for incorporation into its guidelines in 2009.
MoCA 1.1
On October 23, 2007, Entropic Communications announced the first availability of a MoCA 1.1-enabled chipset, scheduled for release in November 2007. Features of the new standard include net data throughput of up to 175 Mbit/s and support for up to 16 devices, two advancements that are important "to accommodate an increasing number of MoCA devices in the home entertainment network of the future".
In 2009 the company announced that this chipset was being used by Advanced Digital Broadcast in its ADB-6882CDMX – the industry’s first MOCA 1.1 certified set-top box.
The alliance publishes a list of certified products.
MoCA 2.0
On June 15, 2010 MoCA 2.0 was ratified. MoCA 2.0 offers 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. For point-to-point WAN applications, performance can be optimized for two node networks with Basic mode delivering 500 Mbit/s net throughput (MAC) and Enhanced mode providing 1 Gbit/s net throughput.
