ITU-T Approves Data Link Layer of G.hn

The International Telecommunication Union (ITU-T) has approved the Data Link Layer (DLL) of the G.hn standard.


The G.hn standard is designed to deliver a unified technology for wired networking. With the Physical Layer, DLL and coexistence protocols essentially complete, G.hn will unify the networking of content and devices over any of wire -- phone line, power line and coax cable. With G.hn, service providers will be able to deploy new offerings, including IPTV, more cost effectively.


In addition, the Smart Grid profile was advanced by the ITU specifically for use in low-complexity applications, including home control and automotive, where G.hn can now be used in plug-in electric vehicles. This low-complexity profile identifies a minimum set of G.hn parameters and specifications for features including: signal bandwidth, data modulation methods, transmitter linearity requirements, and Forward Error Correction (FEC), while maintaining interoperability with fully-featured G.hn products.


"It's exciting to see how rapidly the G.hn standard has evolved to meet the needs of a very dynamic market," said Matthew Theall, president of HomeGrid Forum. "G.hn was originally seen as a multimedia networking technology, and was developed to address that significant market opportunity. Now, thanks to cooperation from throughout the industry, and from ITU and HomeGrid member companies, G.hn is able to address an even broader range of applications and has the potential to enable billions of consumer devices, computers, energy management products, and even automobiles with next-generation connectivity."http://www.HomeGridForum.org
