Great Michael and CA, in the case of another tech with

seems to be great the application of GFast, married with hybrid networks

tech to take advantage of the copper cables in the households. The truth
is that we need to create a basic text to make a movement in our cities
approaching more the theme of digital cities and CNs as part of common good
of the public policy of communication to smart citizens/cities.
Synergies we have a lot, I think that the first step is to organize the
information, make a good presentation, based in those relevant information
and make the movement happen from botton-up-in-between.

Thanks for this Marcello, and you raise good points. On the public-private
partnership idea, it made me think of AT&T's Project AirGig
<http://www.androidpolice.com/2016/09/20/atts-project-airgig-is-the-insane-future-of-ultra-fast-mobile-and-fixed-networks/>
.
ISOC also produced a briefing paper on this back in 2003: Addressing the
Digital Divide with IPv6-enabled Broadband Power Line Communications
<https://www.isoc.org/briefings/013/briefing13.pdf>.
I also want to share an insight that was shared by a colleague who took
DiploFoundation's Intro to Internet Governance course with me last year,
who is from the Cayman Islands.
After one person wrote:
*"I always wanted to see power line communication (PLC)/BPL as a solution
for almost ubiquitous Internet access using an existing infrastructure. It
is an interesting concept, and would seem to offer an amazing option for
improving access. Here is an excerpt from an interesting article
<https://eandt.theiet.org/content/articles/2013/10/whatever-happened-to-broadband-over-power-line/>
on the matter: "The failure to properly define clear international
standards for BPL technology also probably played its part in its demise.
Because they used unlicensed frequencies and voltages which varied from one
country to another, early standardization initiatives were fragmented, and
it was generally up to individual power companies to decide how they
implemented their transmission facilities, leaving the possibility of
problematic interconnection."*
*The PLC/BPL technology was approved in the USA in 2003, but the last
company offering the service closed in 2012, and asked its users to find
alternate sources. Hacking
<http://money.cnn.com/2014/11/18/technology/security/energy-grid-hack/> the
power lines, weather, interruptions in service locally, and interference
are often cited as reasons it has not worked well."*
My colleague from the Caymans said:
*"Sometimes there a valid case for duplication or in the case of Cayman
triplication of the infrastructure network. In addition to a private PLC
used by the sole power company to service their smart meters, we have a
standard copper telecoms infrastructure owned by one of the telecom
providers and 4G mobile coverage island wide (it’s only 76 sq. mi). We are
now also duplicating the copper network with a fiber to the home network
island wide. Although its roll out has not been as fast as hoped and is
definitely running on island time, it has been installed throughout the
majority of the capital and tourist strip. We have we done this and what
could warrant such a massive investment in our telecoms infrastructure?
Hurricanes. The power grid runs above ground and the copper telecom network
underground and the mobile coverage is provided by 8 towers (split between
the 2 providers). In 2004 we were hit by Hurricane Ivan which devastated
the island. The Category 5 winds completely destroyed the power grid which
had to be rebuilt from scratch starting at the power station out (hence the
PLC) and the storm surge took out the backup generators at the majority of
the mobile phone towers since Cayman is only 510 feet above sea level. Yet
even after all the destruction the underground copper network remained
completely functional. In fact, at our house on the opposite side of the
island from the power station, we got our broadband back months before
electricity was restored. Home backup generators are a wonderful thing. By
sheer coincidence we as also duplicating the fiber network that is being
rolled out. The company that owns the copper network is rolling out service
through their underground tunnels and a competitor is running their network
above ground along the electricity poles in the same areas island wide.
This same redundancy also applies to our connection to the outside world.
We have copper undersea cables to the US and Jamaica and between the
islands, fiber optic undersea cables between the islands and Jamaica
(Cayman-Jamaica Fibre System) in addition to being connected to the Maya1
fiber to the US and Latin America. We also have a satellite earth station
used by Intelsat as an additional backup. Not being connected is just not
an option when you're the top offshore financial service center in the
world. (On a side note: The power company actually applied to start
providing broadband service to customers and a number of homes were used as
test cases but their application was turned down because the government of
the time though that being the sole energy provider on island was a good
enough deal for them and government also precluded them from doing so in
the future when they renewed their contract for 25 years (see:
http://www.submarinecablemap.com/#/landingpoint/halfmoonbaycaymanislan…
<http://www.submarinecablemap.com/#/landingpoint/halfmoonbaycaymanislands>)).*
*The only redundancy that is shared between the providers is the access
off island and even then competitors must pay FLOW (formerly Cable and
Wireless) for bandwidth allocation on the fibre systems. Its for this
reason that there are more cell phones than people in Cayman. Everyone has
at least one phone from each provider (a main contract with one and a pay
as you go with the other) to ensure that should one provider's network go
down they have access to the other's network. The reason the power lines
are run above ground is mainly because Cayman is literally a solid
limestone rock which makes trenching a very labour intensive and time
consuming process. When the original power lines were installed in the 60s
and 70s wooden poles were used and 30+ years of weathering combined with
their relatively low height compared to the tree line meant that when the
trees came down they took the power lines with them. The wooden poles were
replaced with concrete poles more that twice their height so the power
lines now run above the tree line making them far less prone to damage from
falling trees."*

Just to know if this information is relevant :
Cisco already told in VNI that 63% of mobile communication will pass
through wifi until 2021. The offload services will rise stronger. In
another way we have the paradigm of smartgrid, that the energy Cos will
need to use telecom infrastructure to control the grid. Here in Brazil at
least the power to regulate the use of soil are from the mayors. Assignment
of space use is a fight between the companies and public power that needs
to implement theirs infrastructures. I think that we need to improve the
organic laws in the cities to organize how the digital policies can happen
in dynamic way, using the “public” infrastructures and resources ordered as
common goods.
Public-private partnership with city hall and companies of basic public
services may happen, building a common infrastructure and providing
benefits to the parts evolved.
This is a beginning to talk about digital cities.
Maybe a movement of neighborhoods around the world to make pressure in
mayors will be great J.

It’s a process. This is why I’m trying to take an approach of setting and
citing examples. In the US I’m trying to work with residential property
owners to provide local connectivity. Building on examples that are
commercial viable and sustainable are the most powerful means. Overall
though I try my best to explain the concepts.
I realize the challenge because even when there are good examples like
Altermundi people just see it through the lens of the telecom narrative. I
also understand the need to work on intermediate approaches to deliver
social benefits. I just want to make sure we understand the difference
between the short term efforts and a longer term direction.

Yes, think about simply mounting things like WiFi repeaters.
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

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
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?
