MoCA 2.0-based chipsets offer Gbit/s data rates

Entropic Communications Inc. said it will sample chipsets to support version 2.0 of the Multimedia over Coax Association (MoCA) home standard by June 2011 enabling support for data rates up to a Gbit/s using a turbo mode with channel bonding.

Officially ratified in June, the MoCA 2.0 spec calls for a base capability of up to 400Mbit/s. Entropic helped pioneer the MoCA technology that carriers such as cable and satellite TV providers have started adopting for providing multi-room digital video recording features on their STBs. The carriers have been calling for at least two years for technology that can handle data rates up to a Gbit/s.

Backers of competing technologies have been working to respond to the demand. The first chips supporting the new ITU G.hn standard for wired home nets has a mode supporting Gbit/s and the HomePlug Powerline Alliance is working on an AV2 spec that aims at similar data rates.

Entropic faces competition mainly from Broadcom which has been supporting MoCA 1.1 in its STB chip sets for at least a year. Broadcom typically does not announce chips until they are shipping.

A growing group of suppliers including Broadcom and Atheros are supporting hybrid home networking standards to reach all the devices and services in the digital home. For its part, Entropic has worked on reference designs using MoCA and Wi-Fi.

Entropic expects to have the version 2.0 chips in full production in early 2012.
