Full Duplex DOCSIS doubles efficiency of spectrum usage for upstream and
downstream traffic flows

CableLabs®,
the leading innovation lab for the secure delivery of high speed data,
video, voice and next generation services, today completed its Full
Duplex DOCSIS® 3.1
specification which significantly
increases upstream capacity and enables symmetric multi-Gigabit services
over existing hybrid fiber-coaxial (HFC) technology. Anticipating a
change in user demand as emerging technologies require more bandwidth,
CableLabs' Full Duplex DOCSIS technology will ensure that cable
operators can be ready to meet future usage needs for technologies such
as virtual and augmented reality.

Full Duplex DOCSIS 3.1 technology builds on the successful completion of
CableLabs' DOCSIS
3.1 specification
, which made deployments of 10 Gbps downstream and
1 Gbps upstream broadband possible.

"In the United States, more than 90 percent of households are connected
to an HFC network, and consumers typically have higher download speeds
than upload speeds," said Phil McKinney, president and chief executive
officer of CableLabs. "By enabling Full Duplex DOCSIS, the upstream and
downstream traffic can flow at up to 10 Gigabits concurrently, doubling
the efficiency of spectrum use."

In current DOCSIS networks, spectrum is typically split between the
upstream and downstream, or spectrum is shared between upstream and
downstream traffic. Full duplex communication enables upstream and
downstream traffic to efficiently use the same spectrum simultaneously,
which can be beneficial for residential and business services. For
businesses in particular, symmetric services can vastly improve network
efficiency, which can, in turn, improve the customer experience on
business websites.

By leveraging the combination of DOCSIS 3.1 technology, passive HFC
network characteristics, self-interference cancellation technology and
intelligent scheduling, CableLabs – along with the collaboration of its
members and other industry partners – developed this solution enabling
full duplex communications over the existing HFC network. The evolution
also eliminates the need and cost of deploying fiber to the home while
still maintaining backward compatibility with previous generations of
DOCSIS technology.

The Full Duplex DOCSIS 3.1 specification effort was initially
announced by CableLabs
in February 2016. The update to DOCSIS 3.1
including the complete Full Duplex DOCSIS specification will be
published on the CableLabs website later this month.
