So is G.hn a Home Networking Standard Yet? You betcha. Can you download it from the ITU's website yet? Not quite but soon.
If you missed it don’t feel too badly but definitely pay attention. After about two years the ITU Q4/15 has Consented (I believe that’s with a big “C”) the remainder of G.hn. If you recall, the ITU Consented the PHY, G.9960, in December 2008. After Consent, the ITU kept itself busy with their finalization process which, for the PHY, resulted in Approval last October. Approval means they can print it and you and I can download it directly from the ITU’s website. Last week the ITU Consented the Data Link Layer (DLL) Recommendation G.9961, the remaining big piece of the pie.
Will we see another press release announcing Approval of G.9961 in
June as planned? Could be. Either way it’s an impressive piece of work
done in a comparatively short amount of time and the authors deserve a
lot of credit.
So what exactly is G.hn? (Yes, I know it’s the greatest home networking standard ever written.) In the ITU, G.hn is a group of people representing companies that paid money to participate in the ITU standards development process and an editor. The G.hn group is actually the same one that developed the HomePNA 3.1 standard Recommendation G.9954 1-07. Going forward, I'd wager that a G.hn product will be one that is designed in compliance with the four recommendations (G.9960 G.9960 Amendment 1, G.9960 Corrigendum 1 and G.9961) which, when taken together, comprise the G.hn standard today. As with other standards like the IEEE's 802.11 a, b, g, n, ..., I expect it will continue to evolve and be known by equally incomprehensible taxonomy.
