Nothing going over the phones is this high frequency. When I was working on ADSL, the highest frequency compenent was 2.5 MHz (it has been awhile)

I think maybe VDSL will be higher (or SDSL) but they are not that prevalent, and VDSL is really unproven at all.

The BPL will have energy up to 80 MHz. But as someone said, it will be hard for the modelers to prove interference, as it will just increase out noise floor. The HAMs have got the real beef.

But imagine all of the phantome shootdowns, they will all get blamed on BPL!
