BPL does the same thing as DSL, modulating several different frequencies so
that, in effect, they have several parallel channels with each carrying a
portion of the message. That gives them the speed (soon to be much, much
faster). While I think they can turn individual frequencies on/off to avoid
any excessive noise at that frequency, the robustness is mostly because they
are using the same methods as Ethernet with the receiver asking for repeats
when there are errors.
