It uses the same concept as broadband over powerlines, which is possible just not secure enough at this time yet. I strongly support broadband over powerlines because its how we're going to get broadband to all the rural areas still on dial-up.
Wow sounds like I can finally take my comp upstairs to my room. (wi-fi doesn't reach there)
But I have a very old house with very old wiring, will I get a slower connection because of that?anything over 1mbps is good right? unless I'm sharing files over lan.
