Don't know about BPL, but VDSL goes from 138KHz to 12MHz and has 4096 tones.
Not as much potential for a problem, as it's all twisted pair rather than
power lines.
And even at that, the VDSL industry has responded to the multiple presentations
I have given to their committees and put in 30 dB notches on amateur spectrum.
It will not be perfect, but those notches will help a lot.
