Data over "Power Lines"

[embromation]

I heard talk about "channel of data + power line" in the same cable. I am curious to know its operation. Someone would have information (circuits, projects) on the subject?

I found this:

hi

check this link please

http://www.echelon.com/products/development/

its for Echelon company the #1 company on data communication over power lines using a protocol of theirs named  LONTalk protocol

the previous link is for their software and hardware tools used to develop application

Hi, this IC`s may be useful:

However, interfacing hardware and protocol depends by type of power lines, 220AC mains is too noisy for high bitrate. Anyway, LC filters are requried.
