We’d like to shed light on some industry FUD surrounding the release of the G.hn standard. You may have heard about a G.hn contribution made last month by some of the bigger telephone companies. The contribution, which was adopted by the members, proposed to consent a G.hn Recommendation (ITU speak for “agree on and publish a standard”) by the end of this year. Service providers are the customers and their opinions count in Q4/15 (see the May 5 post “Who is ITU-T, what is Q4/15, and where did the “G” in G.hn come from?” See blog post. So this contribution, which also prioritized the work, carried a lot of weight – not to mention a warm feeling that the service providers are there to help keep the work on track. This standard will allow technology companies to develop G.hn chips.
After a recommendation is consented it goes through a short ITU release process and becomes an open publicly available standard. This doesn’t mean it can’t be enhanced in the future. In the ITU it is common to have addendums added later. For example, the HomePNA 3.0 spec was initially consented and released as Recommendation G.9954 in February 2005. After HomePNA released the enhanced but backward compatible 3.1 specification, Q4/15 updated G.9954 and re-released it as G.9954 Jan 2007 revision.
