Copper ethernet communication can be conducted over normal AC powerlines if the proper engineering is done on the front end.

It seems using existing AC powerlines would open the market up for Sony and others enabling more users to connect at
a lower cost.

There are many AC powerline communication companies doing business for years but no one has cracked the home market in a big way yet.

I would be very interested in a system.

How interested are you? How much are you willing to pay?
Typically, wireless RF technologies are about a generation ahead of PLC (powerline communcaions) and have 95% of the marketing revenue. PLC has made great progress and there are some very good technologies out now. You will be seeing a great deal more activity in PLC as the wireless spectrum gets more crowded and more applications are wanting connectivity in the house, especially the multimedia servers.

Clearly RF is easier and cheaper to install with some disadvantages.

The article from Sony mentioned,

QUOTE
Designed exclusively for new home construction, these systems are installed at the same time as the home's structured wiring thus significantly reducing installation cost. Each appliance is easily wired using standard low voltage wiring for power and a cat 5 cable for Ethernet, which connects to the home network through a router.


I didn't come across wireless RF technologies in the article ?

Hi all

Are you sure this article is talking of using power cables for the wiring although this idea has been used in limited applications for years in a houshold enviroment the costs wouldd outweigh the benefits, and I can think of all sorts of problems related to moving items, power positions etc.

The article mentions low voltage cabling, power supplies are usually considered medium voltage. I really dont see the benefits of anything mentioned in the article or much in the way of difference than now.

I live in a house over 100 years old but it still has concealed wiring with facilities for easy replacement including phone, speakers and power where's the problem.

There might crop up some problems with using powerlines as broadband medium. Powerlines are often not properly shielded, some aren't even shielded at all. Putting broadband signals on such cables might interfere with other RF stuff like emergency frequencies etc...

Nooooo!!!! You guys are going off the mark here, and confusing this with x-10 type systems.
Where does it mention using the powerlines for signal transmission???
How this system operates is: CAT5 is linked to each unit...(The CAT5 carries the audio signal and command etc.) Now, there is also a low voltage 9 or 12 volt wire goint to each unit (for power only!!!), taht goes back to the head-end of the system along with the CAT5.

Cut back on the coffee & READ the article!!! laugh.gif

You should really check out what SONOS is doing in this arena!
They have a system that works VERY well, and is being well received my Custom Installers and the Audio community.
