where can i buy these?
I'm interested in upgrading my powerline network. When is G.hn available? I saw news a few years ago that it is ready but I've never seen any at the store. Then this article asks if it will be 2014. Just recently I saw a CNET review of a Comtrend G.hn adapter but it doesn't look like it is available anywhere - not even Best Buy. Also, will this work with my existing HomePlug adapters? I have 4 of them at home.

Re: Missed a competitor
John, thanks for the explanation and clarification on P.1905.1. Sounds like a good time for us to pursue an update on that effort.

Re: Missed a competitor
John Egan:

Regarding 1905.1... This is an IEEE standard that was defined to abstract various technologies from higher layers, this way the various, and incompatible APIs, etc., for the technologies were set aside for a common set. The initial standard now only supports IEEE standard 1901 defined powerline communications (2 types - one based on a derivative and advanced version of HomePlug AV (1901 FFT), and one based on a derivative and advanced version of HD-PLC (1901 Wavelet)), MoCA for coax, 802.3 Ethernet, and 802.11 (commonly called "Wi-Fi"). The IEEE in Dec 2013 established a new Project to modify the 1905.1 standard to open it up, for example to support as well HomePNA and G.hn technologies.

However, by the way, the ITU-T as well has stepped in and established a smooth path to add G.hn and HomePNA to the IEEE 1905.1 standard, thus setting a template the new IEEE Project could follow to quickly add these technologies and resolve any misunderstanding that 1905.1 is a competing technology to G.hn. We, at HomeGrid Forum, are hopeful the Open Stand commitment of IEEE is quickly reflected in the modifications to 1905.1 to make it an open standard to benefit the all of the market, instead of being narrowly defined to help only a select number of technology suppliers and technologies.

I have one disagreement to the article and that has to do with "deployments being unexpectedly slow." This slowness is not due to a lack of market demand for the technology, it has to do with the realities of G.hn being a brand new technology, whose standards were only completed in 2010. Typically it has taken new technologies, like 802.11, VDSL2, ADSL, etc. 4 years to go from standards completion to an interop demo. G.hn did this in under three years, with already silicon and system certification available and awarded to certian vendors. While we wish we could have delivered even faster, we continue to set records today as we deliver the state of the art in home networks.

Re: Missed a competitor
I think WiFi did sli[ in a steal some of G.hn's thunder when the latter's products didn't materialize quickly enough. Wasn't there also a competing standard - IEEE P.1905? - that was going to leverage WiFi and MoCA, among others? I don't know off-hand where that stands, but would be interested to find out.

Re: Missed a competitor
Aren't most devices in the home NOT set tops/TVs?

Seven- most TVs/set-tops still connect over MoCA in the US.

Missed a competitor
For most applications isn't home WiFi the basic competitor?
