[...] Stacey Higginbotham | Sunday, May 31, 2009 | 9:00 PM PT | 0 comments Wireless networking gets all the love in today’s mobile world, but inside the home, wires will still play a key role in delivering entertainment and other content. Your set-top box may sport an Ethernet port, but it still connects to the wall via coaxial cable. Wires are a secure, fast, cheap and existing network inside most homes. The main links around the home are power lines, coaxial cable, copper phone wires or some mix of the three, depending on where in the world a person lives. But the three standards vying for dominance today could gradually give ground to an emerging standard for delivering IP-based services called G.hn. [...]

[...] If the G.hn standard takes off, it will make life difficult for specialty chip makers such as Intellon (itln), which makes HomePlug chips, or Entropic, which makes MoCA chips. Source. [...]

Rob, I have been told that if at the PHY layer it’s 100 percent efficient then at the MAC layer it’s about 70 percent efficient.

Let’s read the fine print. Not all service providers are represented by ITU. Where are the cable and satellite providers?

Is 800 Mpbi/s sec “in practice?” a PHY rate or a MAC rate? This is the difference between what is promised and what is actually received?

What about backward compatibility with other standards already in use and deployment? Are people supposed to throw out the equipment they already have?

Are there any plans for field tests?

This is an attempt to unify very different mediums. Does this mean performance will be the same across all mediums?

it could be 2010 and much later by time silicon and products are available, Do you honestly think the standards groups are going to sit idly by? By time G.hn is available, it could end up being the slowest kid on the block.

Michael, thanks for your answers. Majortom, I am jealous but for most, it will be an improvement over existing wired networks.

Let me address both comments:

G.hn is supported by service providers such as AT&T, British Telecom and many others. They love the idea of a faster standard that has multiple chip suppliers. In addition, G.hn will lower installation times (and therefore costs). Service providers crave that feature.

Regarding Cat-5 gigabit networks, G.hn will not be faster than that. However, g.hn is an “existing wire” solution – products that use existing coax, phone or powerlines in the home. The average customer doesn’t have Cat-5 throughout the house (to every TV) and delivering IP over existing wires is about 50% less expensive for service providers.

In practice, G.hn supports throughputs up to around 800 Mbit/s over coax. The best performance today is HomePNA at around 200 Mbit/s of continuous throughput. This will allow for substantial increases in new home applications such as whole home DVR, next generation TV technologies like Ultra HD, etc. and other applications being contemplated.

How is it faster then wired? My network at home is gigabit.

I understand the desire to find a standard here, and I agree that with time the one-specialty chip makers will struggle, but I wonder about this new standard. It sounds good. It sounds too good. Faster. Covering more physical transmission layers. One chip for all devices. And all of this available by 2010 or 2011. I wonder what the operators will have to say about this
