Service Providers are Embracing G.hn

Key Service Providers are realizing the benefits of G.hn. HomeGrid Forum members include Chunghwa Telecom, British Telecom, AT&T, Telefonica and more.

Here is a recent quote from analyst Jeff Heynen of Infonetics:

“HomeGrid Certified G.hn was built from the ground up with Service Provider contributions around manageability, robustness, quality, and coverage in the home. All these issues are being addressed with G.hn. It offers whole home coverage for multiple HD IPTV streaming and no new wires need to be installed in the home. It could be a real game changer for Service Providers.”

G.hn: What's it all mean?

 A lot has happened in the last few weeks for G.hn. The PHY was Approved, the coexistence mechanisms achieved Consent and the DLL was deemed stable. The first semiconductor products were announced.  New IP has been made available for licensing.  And much more.  Find out what it all means by downloading the latest webinar from HomeGrid Forum entitled Wired Networking Inflection Point. 

Major Progress in Geneva, First Product Announcements

Last week, the ITU-T made significant progress on the G.hn standard -- Approving the PHY and architecture, advancing the DLL and providing Consent to the complementary coexistence Recommendation G.9972 (aka G.cx).  These moves were supported by service providers, consumer electronics manufacturers, semiconductor companies and countries from around the world, and set the stage for G.hn to emerge as the single unified wired home networking standard.

Following the announcement of the ITU-T's accomplishments, several HomeGrid member companies publicized their support and first G.hn products.  DS2, for instance, confirmed its plan to launch its G.hn-compliant DSS9960 chipset next year.  Ikanos announced its support for the technology. And there will be many more announcements in the coming weeks.

G.hn: data rate analysis

This blog post ("How fast can G.hn be?") includes a detailed analysis of the maximum theoretical performance we can expect from the G.hn standard when operating over coaxial cable.

[...] actual throughput provided by any communications technology is heavily dependent on both the PHY (Physical Layer) and DLL (Data Link Layer) design. [..] Although the PHY for G.hn is described in Recommendation G.9960, which received consent in December 2008, the most important aspects of the DLL have not become stable (ie, become "baseline", using ITU-T terminology) until April 2009. With both PHY and DLL in place, we can now work out some numbers to estimate how fast a G.hn implementation could run in theory.[...]

Update on G.hn from HomePNA

The HomePNA Alliance, which in February announced its plan to work with HomeGrid Forum and other organizations to promote the G.hn standard, has posted an update on G.hn on their blog:

In case you were wondering, G.hn is continuing to astound standards watchers by making good progress. Work at the April meeting, held the week before last, focused on two areas – resolving the remaining comments on the “foundation” document and new submissions on the G.hn MAC.
