It's a new technology, the FCC cannot determine all the affects until it has been tested which is what the TRIALS are all about.
The only thing new is the fact they have hardware that will hook up to the power transmission lines at a price that may let them make a profit. Power line technology has been around for years, I built a small system back in collage (1979-80) that transmitted a primitive digital signal using the power line that a doctor's office could use for a set of coded light panels. Even at that low power, the AM radio would pick the pulses when sitting next to a power line run. Second or third harmonic if I recall it correctly.
I do not remember how it was interfaced, I was doing the signaling portion and I do not even remember how I did that!

Baxter, KY | New as in NEW to this country using a different type of technology than has been used. Transmitting a simple signal is much different than trying to run an ISP using power lines. If THAT was an older technology in this country, we wouldn't need trials everywhere.

Well, if that is your definition of new then I have to grant you that point (btw, my project and others WERE done in the US of A). To me, the only thing new is the fact that they can now make the devices cheaply enough, lossless enough, yet still handle the power levels (both line and signal), and that there is a potential market base to have a chance at making a profit.
You are right about the difference in interference between my simple (now) project and the current ISP over power line trials. An ISP over power line will have a much more massive affect on the RF environment. The only thing we will see are studies that will be massaged to return data like '4 out of 5 doctors surveyed'. I know, I work for the gov and see it all the time from contractors.
