I absolutely agree Bob, but then the question becomes how to facilitate
that transition of ownership?

A simple way to think about it is to ignore the accidental properties of
the copper wires except as one optional radio medium. What the companies
really have is ownership of the poles as real estate. Like railroads have
become real estate companies and Sprint (SP as in Southern Pacific) was a
company that start by taking advantage of the railroads right of way. It
becomes even more absurd when we treat radio frequencies as property. One
reason why copper is interesting is the original reason why Ethernet was on
coax -- it was ALOHAnet on a contained radio medium that avoided others'
regulations.
If we step back, especially in the US, we have to wonder why the poles are
still owned by power companies and phone companies as a legacy of bad
metaphors. When work has to be done on poles there are complex regulations
and rental schemes. It's time to move on to more rational models with
communities owning those rights of way so we don’t have legacy rent-seekers
limiting our ability to communicate.
That won't happen on its own but that's the normative model to look
forward to once there are examples to point to.

A major problem is signal interference -- both from the power lines
themselves onto the modulated signal and radio interference by the
propagation of relatively low frequency waves along unshielded lines with
no harmonics suppression. Also, modulated signals are unable to "jump"
transformers, which require adaptations on these points.
Power line wifi repeaters may work nicely in internal premises though.

First, I need to preference this is that I’m
answering this in terms
of the US and the issues are different elsewhere.
I’ve followed this issue over the years and there
is a lot of mythology.
The problem is the US is primarily political and
economic. If the
communities own their wires they could easily
light up the copper to
many megabits or gigabits per second. Unlike
cities it is far easier
to add wired and wireless capacity. The real
costs are actually very low.
What is expensive is taking a 1950’s type
approach to use the facilities.
The other twist in the US is the cockamamie idea
that the distribution
system has to be a profit center like railroad
tracks rather than
infrastructure like roads.
The other twist is that the 20 years of
interesting using power lines
goes back to the power companies thinking there
is money in “Internet”
so they want to use their wires which just happen
to be copper – the
same mineral that is used Ethernet thus they can
make big bucks
selling Internet alongside electricity. But if
you read their whole
pitch it becomes obvious that they are
institutionally the worst
choice. They make the phone and cable companies
look agile.
So we get back to the simple idea of communities
owning their
facilities. If they have access to the poles and
existing copper and
the ability to invest in their own gear and take
Internet native
(http://rmf.vc/InternetNativePolicies) instead of
use telecom pricing
and policies the limitations would disappear
rather quickly.

Hi everyone,
I just read this Interesting article:
a-broadband-look-to-the-early-1900s.html
I know the idea of providing Internet via power
lines is more or less
a defunct idea (not due to technological
constraints, but the lack of
political will to invest in it to protect
existing revenues). However,
has anyone on this list ever thought about
working with electricity
companies, especially local power companies?
Best,
-Michael
