G.hn is the name for the upcoming wireline home networking standard developed under the umbrella of the International Telecommunication Union (ITU-T).

The standard is applicable for a broad range of wireline media and specific parameter sets exist for communication over power line, phone line and coaxial cable.

Till now the standard comprises the ITU Recommendations G.9960 (Physical Layer) and G.9961 (Data Link Layer), as well as the Recommendations G9972 (Coexistence) and G.9970 (Transport Architectures).

G.hnem is a project within ITU-T (SG15) that deals with "Home Networking Aspects of Energy Management". The special aim is to derive a narrowband  physical layer/data link layer specification, to be implementable by low cost equipment used in energy management applications. The standard will comprise home network and access network aspects of energy management, and collaborations with related standardization bodies are in place to assure a harmonized upper layer protocol stack with standards like ZigBee/IEEE 802.15.4-2003 and Z-Wave.
