Early comment

I extensively edited the page based on the limited publicly available information. Since this project is primarily in stealth mode, I chose to give only limited coverage to material that originated at a press conference of interested parties.

In the small paragraph where you point out the potential detrimental effect on amateur radio and how that was recognised, surely this affects many radio bands, and not just those used by amateurs. Don't you need to explain exactly which radio bands and who will be affected?Dixx (talk) 09:50, 1 March 2009 (UTC) References: RSGB debate about powerline interference.

Integration with demand side management, ECM, AMI, MDU and utility access

Original text moved from main page to this discussion page:

"G.hn does not cover access networking that is used for MDU and utility access applications," and so does not support demand side management directly. Nor does it specify any particular interface to powered Ethernet which enables DC devices to participate (eliminating so-called "vampire power" draw from inefficient transformers. However, it is easily integrated with home grid and smart grid technologies - the IEEE P1901 standard for BPL/PLC specifies G.hn as the primary target for supporting such capabilities. ^[1]

Relatively low utilisation of generation and networks (of about 50% in the UK), aging assets, the growth in renewable and other low-carbon generation technologies, security and home control and medical monitoring are all good reasons to deliver G.hn on smart grid platforms. Barriers include a lack of metering, information and communication infrastructure, lack of understanding of the benefits of DSM, problems with the competitiveness of DSM when compared with traditional approaches, an increase in the complexity of system operation and inappropriate market incentives. ^[2]

Some problems that I see with this text (and why I think it's not ready to be included in the main page yet):

Although it's true that G.hn has not been designed for utility applications, that does not mean that it cannot be used for demand side management. Those are two orthogonal issues. Somebody could use technology X in the access networks and technology Y in the in-home network in order to build an end-to-end demand side management system.
It's not true that G.hn does not specify support for DC-powered devices. G.hn can also operate over DC wires.
I don't think that the reference to "Smart Grid Today" says what you claim it says
The text on "low utilisation" may be correct, but I don't think it's relevant for the G.hn page. A reference to the Smart Grid wikipage would probably be better.

In any case, I think that after editing it a bit, this will fit well in "Applications" section of the main page. Itusg15q4user (talk) 23:06, 16 May 2009 (UTC)

G.hn final approval

We should not tell people G.hn (exsp. G.9960 and G.9970) are "ratified" until they are available on www.itu.int/rec/T-REC-G or ITU itself pubishs a statement which confirms the final approval. --Kgfleischmann (talk) 09:49, 10 October 2009 (UTC)

Of curse, you may a more differentiated picture of the thing, as described in you reference(). --Kgfleischmann (talk) 13:12, 10 October 2009 (UTC)--Kgfleischmann (talk) 13:12, 10 October 2009 (UTC)

Hi, I think the source provided (HomeGrid Forum press release: ) is adequate. It includes quotes from at least two ITU officials. Additionally, other releases from companies involved in G.hn (see ) confirm that the approval indeed happened in Oct 9th, even if ITU has not yet published Recommendation G.9960 in their website. Advancedtelcotv (talk) 15:23, 10 October 2009 (UTC)

The reference writes "HomeGrid Forum today announced that International Telecommunication Union (ITU-T) has successfully agreed upon the key components of the G.hn specification at its meeting held at the United Nations in Geneva. As a result of this agreement, ITU-T will publish an Approved G.hn Recommendation for the Physical Layer (PHY) and architecture portion of the standard." If the IP had written this and no interpretation of it I had not complained. --Kgfleischmann (talk) 15:38, 10 October 2009 (UTC)

Update

Added "Advocates for existing technologies point out they have shipped millions of chips for coax and powerline while as of June, 2010, there are no G.hn chips available." to balance the claims of proponents. Whether H.gn will do in practice what proponents claim is disputed, as is whether it will be as widely adopted as the article suggests. (No one knows yet, so it's appropriate to present both sides.) Removed sections about companies that largely duplicated the names in the Home Grid Forum section and was replete with inaccuracies. (Metanoia doesn't make DSL chips, Infineon spun off the division as Lantiq, etc. Mostly redundant anyway. If I had time, I'd remove more of the hype. I almost flagged the article. DaveBurstein (talk) 23:43, 10 June 2010 (UTC)

David, As much as I respect your opinion and diligence in getting facts straight, I see that you're mistaken regarding Metanoia and DSL (see http://www.metanoia.com.tw/product.php), and may have made a few other mistakes in your editing of the G.hn topic as well. I'll review what you have done and see if further corrections are in order. John Egan 20:28, 23 June 2011 (UTC) — Preceding unsigned comment added by Oldmanegan (talk • contribs)

Why not just state the facts and leave out the opinions of both G.hn proponents and advocates of other technologies? I came here looking for facts about G.hn, and I found what I was looking for, but I had to sift through a truckload of opinions and promotional litter to find it. I can do my own research on silicon vendors and prevailing opinions, thank you very much. Lambtron (talk) 22:02, 23 February 2012 (UTC)
