Study Group 15 has consented on a revision to a home networking specification
that increases data rates over existing home wiring to 320 Megabits per second.
original standard (ITU-T Recommendation G.9954) is based on input from the HomePNA
alliance. The revision adds home networking over existing coax cables to
networking over phone wires. The revision also includes new operating
spectrums adding VDSL coexistence to the ADSL, POTS and broadcast TV channel
spectrum coexistence provided by the original standard.
facilitates interoperability and convergence of all networked IP data in the
home by creating open, interoperable standards and best practices for a
universal home networking market. Telephone service providers have collaborated
with residential gateway, set-top box, bridge, consumer electronics (CE)
equipment, and ONT manufacturers, as well as their component providers, to meet
consumer demand for bundled multimedia home networking.
networking bandwidth requirements will steadily increase as operators deliver
multi-stream high-definition content, upgrade last-mile access network
technologies, and provision future IP-based services. Leveraging existing home
wires, service providers can reduce installation, operational expenses and even
end-user costs. Experts say that 320 Mbps can accommodate the future bandwidth
requirements of service providers as they enhance their offerings with
additional features and capabilities.
