Thinking Outside the Internet BoxFriday, August 28, 2009 at 11:15 AM EDT
A couple days ago I responded to a posting on an email list. What I wrote
struck a few chords, so I thought I’d repeat it here, with just a few
edits, and then add a few additional thoughts as well. Here goes.
Reading _____’s references to ancient electrical power
science brings to mind my own technical background, most of which is now also
antique. Yet that background still informs of my understanding of the world,
and my curiosities about What’s Going On Now, and What We Can Do Next.
In
fact I suspect that it is because I know so much about old technology that I am
bullish about framing What We Can Do Next on both solid modern science and
maximal liberation from technically obsolete legal and technical frameworks
— even though I struggle as hard as the next geek to escape those.
(Autobiographical digression begins here. If you’re not into geeky
stuff, skip.)
As a kid growing up in the 1950s and early ’60s I was obsessed with
electricity and radio. I studied electronics and RF transmission and reception,
was a ham radio operator, and put an inordinate amount of time into studying
how antennas worked and electromagnetic waves propagated. From my home in New
Jersey’s blue collar suburbs, I would ride my bike down to visit the
transmitters of New York AM stations in the stinky tidewaters flanking the
Turnpike, Routes 46 and 17, Paterson Plank Road and the Belleville Pike.
(Nobody called them “Meadowlands†until many acres of them were
paved in the ’70s to support a sports complex by that name.) I loved
hanging with the old guys who manned those transmitters, and who were glad to
take me out on the gangways to show how readings were made, how phasing worked
(sinusoidal synchronization again), how a night transmitter had to address a
dummy load before somebody manually switched from day to night power levels and
directional arrays. After I learned to drive, my idea of a fun trip was to
visit FM and TV transmitters on the tops of buildings and mountains. (Hell, I
still
do that.) Thus I came to understand skywaves and groundwaves, soil and salt
water conductivity, ground systems, directional arrays and the inverse square
law, all in the context of practical applications that required no shortage of
engineering vernacular and black art.
I also obsessed on the reception end. In spite of living within sight of
nearly every New York AM transmitter (WABC’s
tower was close that we could hear its audio in our kitchen toaster), I
logged more than 800 AM stations on my 40s-vintage Hammarlund
HQ-129x receiver, which is still in storage at my sister’s place.
That’s about 8 stations per channel. I came to understand how two-hop
skywave reflection off the E layer of the ionosphere favored flat land or open
water midway between transmission and reception points . This, I figured, is
why I got KSL
from Salt Lake City so well, but WOAI from San Antonio hardly
at all. (Both were “clear channel†stations in the literal sense
— nothing else in North America was on their channels at night, when the
ionosphere becomes reflective of signals on the AM band.) Midpoint for the
latter lay within the topographical corrugations of the southern Apalachians.
Many years later I found this theory supported by listening in Hawaii to AM
stations from Western North America, on an ordinary car radio. I’m still
not sure why I found those skywave signals fading and distorting (from multiple
reflections in the very uneven ionosphere) far less than those over land. I am
sure, however, that most of this hardly matters at all to current RF and
digital communication science. After I moved to North Carolina, I used Sporadic E
reflections to log more than 1200 FM stations, mostly from 800 to 1200 miles
away, plus nearly every Channel 3 and 6 (locally, 2,4 and 5 were occupied) in
that same range. All those TV signals are now off the air. (Low-band VHF TV
— channels 2 to 6 — are not used for digital signals in the U.S.)
My knowledge of this old stuff is now mostly of nostalgia value; but seeking it
has left me with a continuing curiosity about the physical world and our
infrastructural additions to it. This is why much of what looks like
photography is actually research. For example, this
and this.
What you’re looking at there are pictures taken in service to geology
and
archaeology.
(End of autobiographical digression.)
Speaking of which, I am also busy lately studying the history of copyright,
royalties and the music business — mostly so ProjectVRM can avoid banging into any of
those. This research amounts to legal and regulatory archaeology. Three
preliminary findings stand out, and I would like to share them.
First, regulatory
capture is real, and nearly impossible to escape. The best you can do is
keep it from spreading. Most regulations protect last week from yesterday, and
are driven by the last century’s leading industries. Little if any
regulatory lawmaking by established industries — especially if they feel
their revenue bases threatened, clears room for future development. Rather, it
prevents future development, even for the threatened parties who might need it
most. Thus the bulk of conversation and debate, even among the most progressive
and original participants, takes place within the bounds of still-captive
markets. This is why it is nearly impossible to talk about Net-supportive
infrastructure development without employing the conceptual scaffolding of
telecom and cablecom. We can rationalize this, for example, by saying that
demand for telephone and cable (or satellite TV) services is real and persists,
but the deeper and more important fact is that it is very difficult for any of
us to exit the framing of those businesses and still make sense.
Second, infrastructure is plastic. The term “infrastructureâ€
suggests physicality of the sturdiest kind, but in fact all of it is doomed to
alteration, obsolescence and replacement. Some of it (Roman roads, for example)
may last for centuries, but most of it is obsolete in a matter of decades, if
not sooner. Consider over-the-air (OTA) TV. It is already a fossil. Numbered
channels persist as station brands; but today very few of those stations
transmit on their branded analog channels, and most of them are viewed over
cable or satellite connections anyway. There are no reasons other than legacy
regulatory ones to maintain the fiction that TV station locality is a matter of
transmitter siting and signal range. Viewing of OTA TV signals is headed fast
toward zero. It doesn’t help that digital signals play hard-to-get, and
that the gear required for getting it sucks rocks. Nor does it help that cable
and satellite providers that have gone out of their way to exclude OTA
receiving circuitry from their latest gear, mostly force subscribing to
channels that used to be free. As a result ABC, NBC, CBS, Fox and PBS are now a
premium pay TV package. (For an example of how screwed this is, see
here.) Among the biggest fossils are thousands of TV towers, some more than
2000 feet high, maintained to continue reifying the concept of
“coverage,†and to legitimize “must carry†rules for
cable. After live audio stream playing on mobile devices becomes cheap and
easy, watch AM and FM radio transmission fossilize in exactly the same ways.
(By the way, if you want to do something green and good for the environment,
lobby for taking down some of these towers, which are expensive to maintain and
hazards to anything that flies. Start with this list
here. Note the “UHF/VHF transmission†column. Nearly all these
towers were built for analog transmission and many are already abandoned. This
one, for example.)
Third, “infrastructure†is a relatively new term and vaguely understood
outside arcane uses within various industries. It drifted from military to
everyday use in the 1970s, and is still not a field in itself. Try looking for
an authoritative reference book on the general subject of infrastructure. There
isn’t one. Yet digital technology requires that we challenge the
physical
anchoring of infrastructure as a concept. Are bits infrastructural? How about
the means for arranging and moving them? The Internet (the most widespread
means for moving bits) is defined fundamentally by its suite of
protocols, not by the physical media over which data travels, even though
there are capacity and performance dependencies on the latter. Again, we are in
captured territory here. Only in conceptual jails can we sensibly debate whether
something is an “information service†or a “telecommunication
serviceâ€. And yet most of us who care about the internet and
infrasructure do exactly that.
That last one is big. Maybe too big. I’ve written often about how hard it is
to frame our understanding of the Net. Now I’m beginning to think we
should admit that the Internet itself, as concept, is too limiting, and not
much less antique than telecom or “power gridâ€.
“The Internet†is not a thing. It’s a finger pointing in
the direction of a thing that isn’t. It is the name we give to the sense
of place we get when we go “on†a mesh of unseen connections to
interact with other entitites. Even the term “cloud“,
labeling a utility data
service, betrays the vagueness of our regard toward The Net.
My friend Erik Cecil has been
thinking lately about how networks are something other than the physical paths
we reduce them to. He regards networking mostly in its verb form, and as what
we do with our freedom — to enhance our intelligence, our wealth, our
productivity, and the rest of what we do as contributors to civilization. To
network we need technologies that enable networking in maximal ways. This, he
says, requires that we re-think all our public utilities — energy,
water,
communications, transportation, military/security and law, to name a few
— within the context of networking as something we do rather
than something we have. at low cost and with restrictions that are
going down, even as regulators seek to drive them up.
The social production side of this is well covered in Yochai Benkler’s
The Wealth of
Networks, but the full challenge of what Erik talks about is to re-think
all infrastructure outside all old boxes, including the one we call The
Internet.
