Faster Home Networking MoCA 2.0 Spec Ratified
SAN RAMON, CALIF.: The Multimedia
over Coax Alliance has ratified its next-generation specification, MoCA 2.0.
MoCA defines the technology spec for home entertainment networks.
MoCA says the following about 2.0: It “offers two performance modes, basic and
enhanced, with 400 and 800 Mbps net throughputs (MAC), using 700 Mbps and 1.4
Gbps PHY rates, respectively.”
MoCA 2.0 is fully backward compatible with 1.1 and 1.0, and doubles the
performance of 1.1.
“For point-to-point WAN applications, performance can be optimized for two-node
networks with basic mode delivering 500 Mbps net throughput (MAC) and enhanced
mode providing 1 Gbps net throughput,” MoCA said. “The new specification also
features an expanded operating frequency range to serve an even broader array
of use cases and two-network wide, low power-saving modes.”
MoCA said the 400 Mbps baseline throughput level is achieved via higher
modulation and expanding the operating channel from 50 to 100 MHz. The enhanced
800 Mbps performance is achieved through channel bonding. Packet error rate has
also been improved to one per 100 million. The PER mode is programmable to accommodate
the needs of content.
“On time delivery is assured with an average latency of less than 3.5ms across
all received packets and traffic profiles,” MoCA said.
Sleep and stand-by modes for networked devices has also been added to the spec,
and its operating frequency range was expanded to between 500 and 1650 MHz.
MoCA has more information on the spec at “Introducing
MoCA 2.0.”
