Then there's the fact that the HF losses on power lines are so high that
BPL
systems need a repeater every few thousand feet. In rural areas that may
mean a
repeater for each customer, or more. Plus couplers and other hardware for
*each* customer.

The slides I've seen presented by BPL marketing fluff folks show repeaters
every
300 meters ... that's a hell of a lot of repeaters to "serve rural America"
.... yet they
claimed in the same presentation that it was "low cost because no
infrastructure was
required because the wires were already (presumably) there."

I pointed to their block diagrams with fiber to the area, "head-ends" to go
from fiber
to the MV/HV lines, repeaters every 300 meters, couplers, etc. and asked
"How can
you claim with a straight face that this "doesn't require the installation
of infrastructure?""
