 In a nutshell, these are simply femto-cells that are linked to eachother via and RF backbone.  No reliance on wires at all.  The only association that they have to power lines is that they are co-located on utility poles. -Ev

 I mean microwave and up high frequencies.  It sounds like 60g based on the other reply.  If so, then high power wave guide binding to the copper wire would be possible and it would be extremely clean of RFI it would seem.

There's no guarantee that journalist knows that high frequency means HF.

That is not what I see. The first part of the article talks specifically about high frequency signals over copper wire. If they go high enough in frequency, the radiation into the atmosphere will be short lived, and the can use higher voltages to get longer distances. The second part of the article talks about additional work on using RF to the home instead of physical fiber so that they can maintain their work within the right-of-ways and not have to run anything physical to your home, where trees and other debris end up destroying services in weather events.

I thought fibre to the home was finally going to put this one to bed - you can push far more bandwidth down a glass pipe than a copper one anyway, with far less interference to OR FROM people like us, emergency services, radio astronomy, etc, not to mention better EMP resiliency.
