When
something works so well for business it is only natural
to assume that it can apply to vacations too. After
all, if you take your laptop and stay in touch with
the office, you aren’t really running away on vacation.
You’re merely changing the initiation point of your
office e-mails. Of course, this presumes that the Internet
exists where you are going.
Last
month I spent a week vacationing near Manchester, Vermont.
To make a long story short, I knew I was in trouble
when the innkeeper said, "Wideband what?"
when I asked about connecting to the Internet. It was
either make a long-distance telephone call to New York
for the nearest IP, or hunt for one of the few local
businesses with a cable modem connection. None of these
included the hotels. Evidently the leaf peepers who
overwhelm Vermont every year prefer low-tech entertainment
like beer and brat. According to the innkeeper, the
first communication priority, if any, would be to add
some cell phone service. Welcome to a black hole.
The
search wasn’t going to be easy and it called for desperate
measures. From everything I could tell, the only pastimes
in Manchester are either shopping in one of the local
factory outlets or hanging out at one of the many restaurants
and cafes while waiting for the next factory outlet
to open. If there is a hip cafe with Internet service,
no one seemed to know where it is. I decided the only
way to find an Internet connection in this town was
to take PC in hand and go war driving.
War
driving is when you go driving through a neighborhood
with a wireless-enabled notebook computer and map houses
and businesses that have wireless access points. War
driving comes from a play on the older term "war
dialing." Film buffs should recognize war dialing
from the 1983 movie War Games with Matthew Broderick,
in which his character uses an IMSAI computer to automatically
call telephone numbers looking for any modem-connected
games and bulletin-board systems. He inadvertently ends
up with a direct connection to a high-level military
computer that gives him control over the U.S. nuclear
arsenal. Obviously, everything hits the fan after that.
If
there was a coffee house with Wi-Fi, I could simply
tell by turning on my laptop and driving down the street.
So, with my trusty Sony TR3A (3 lbs, 10.6²
screen) on the dashboard, I drove through Manchester’s
two main streets and looked for traces of 802.11b. To
my amazement, I picked up seven different signals in
2 miles. None were encrypted!
I
got a signal outside one cafe in the center of town.
As I walked in with my computer, the screen popped up
with a little notice saying that Internet service was
$6.95 per day and I should sign up now. I noted the
location as a backup in case I couldn’t find free service
someplace else. About 10¢
out the cafe door, I picked up a much stronger Wi-Fi
signal with a random-looking alphanumeric ID. There
wasn’t any commercial business that looked like it could
be the source. Curious, I clicked on Internet Explorer
and instantly my home page appeared. I had no idea whose
Wi-Fi it was, but what the heck, it worked. I got back
in my car and downloaded my e-mail.
After
my quick unofficial access, I decided to see whether
or not the other five signals I had picked up could
be accessed as easily. It turned out that three allowed
me to connect with no trouble. The other two did not
register as encrypted, but they did not allow me access
for some reason, which I did not pursue. Certainly,
if I had made a directional antenna out of a coffee
can like most war drivers, I might have picked up many
more signals, but my exercise was to get a quick e-mail
fix, not hijack all the Wi-Fi hot spots in Vermont.
The
best news was that I did indeed find a free Internet
cafe among the seven signals I trapped. One of the great
attractions in Manchester is the Northshire Bookstore.
Recently they added a large cafe that includes free
Wi-Fi along with a computer for public use. Thanks to
Northshire, now it’s cappuccino with Wi-Fi.
Of
course, this discussion can’t help but bring up the
question of Wi-Fi connection legality. Unfortunately,
every government entity has an opinion and an equally
ridiculous unenforceable consequence to go along with
it. The all too typical pattern of legal thought these
days is to presume that the guy who installs the unencrypted,
publicly placed so everyone can trip over it, omnidirectional
broadband transceiver has no responsibility. It’s the
unfortunate sop with a laptop who happens to walk within
range of this transmission who is the bad guy. Come
on now.
The
age of passing the buck has to stop. If we are going
to have laws governing Wi-Fi and similar wireless technologies,
it should be presumed that anything with public access
is fair game if it isn’t encrypted or otherwise encoded
to prohibit access. Instead of blaming the guy sitting
in a coffee shop picking up a signal with his laptop,
people should be forced to take responsibility for their
Wi-Fi transmission when they install it. If they don’t
want it to be public, they should turn on the safeguards.
Accessing a public signal should not trigger legal consequences.
But, hacking a signal when someone has taken pains to
tell you that it isn’t public should.
