It&#x27;s a nice callback to early phone infrastructure, which leveraged barbed-wire fences to bring service to those who lived in rural areas: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Barbed_wire_telephone_lines" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Barbed_wire_telephone_lines</a>

People might find it intersting to know that in the car industry Gigabit Ethernet over unshielded twisted pair is common [1] since it allows to shave off some cents on extra copper.<p>[1] <a href="http:&#x2F;&#x2F;www.marvell.com&#x2F;company&#x2F;news&#x2F;pressDetail.do?releaseID=7256" rel="nofollow">http:&#x2F;&#x2F;www.marvell.com&#x2F;company&#x2F;news&#x2F;pressDetail.do?releaseID...</a>

It would be neat to have a mesh topology that uses the bandwidth and redundancy of multiple fence paths in order to prevent an outage from damage to any one particular fence. Solar-powered routers anyone?<p>Otherwise: <i>Dabnabbit Maude, the cows gone loose again because we lost the interwebs.</i> (I’m half-Texan so it’s not -ist.)

Too bad there are sanctions against North Korea, it seems like this would be a perfect fit for Kwangmyong[1].<p>[1]<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kwangmyong_(network)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kwangmyong_(network)</a>

Can I run this on a farm?<p>Seriously, this reminds me about the stories I read on HN about how early telephone networks were established by farmers (ab)using their electric fencing for communication.

Are there modules I can experiment with?<p>Related link: <a href="https:&#x2F;&#x2F;books.google.com&#x2F;books?id=mMJxcWqm_1oC&amp;pg=PA34&amp;lpg=PA34&amp;dq=Broadcom%27s+T4&amp;source=bl&amp;ots=73okOWEqdp&amp;sig=1iIW9NPoRbzneLPEiq8X0NyVk44&amp;hl=en&amp;sa=X&amp;ved=0ahUKEwig1qmA9YbYAhXH1CYKHZB7C1YQ6AEIMDAB#v=onepage&amp;q=Broadcom&#x27;s%20T4&amp;f=false" rel="nofollow">https:&#x2F;&#x2F;books.google.com&#x2F;books?id=mMJxcWqm_1oC&amp;pg=PA34&amp;lpg=P...</a>

&gt; In 1998, Wide-Band Systems demonstrates Gigabit Ethernet running on four pairs of old, rusty barbed wire.<p>Yet in 2017 we still have only 1Gbit Ethernet in LANs :(<p>1Gbps = 125 MB&#x2F;s !!<p>I am running 1Gbit since 2003 at home. And all f..king home network devices still support only 1Gbit Ethernet. It&#x27;s not fast enough. When can some network company finally release 10Gbit or 100Gbit Ethernet (copper or fiber) for cheap home usage.
