HF seems unlikely.

For quite a few years, the phoneline networking standard has been
delivering up to 10 Mb/sec by using a residential telephone line
(http://www.homepna.org/products) to carry a fraction of the HF
spectrum.

1 Mb/sec seems to be *easily* achievable at HF. It's already
been done.

Sorry. One Megabit data rates over "residential telephone lines"
that INCLUDE already-installed telephone cables and switching
centers in the transmission path is NOT a given everywhere.

Higher-than-1-Megabit rates are possible with "category" cable
and special terminal transceivers for IN-Home networking. That
is NOT the same as the BPL under discussion.
