ITU-Tís 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.

The 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.

G.9954 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.

Home 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.
