Lanlink Linking The Coasts 340
Dan Bricker writes "A guy in Parma Heights, Ohio has a website to promote an idea of linking the east coast to the west coast using standard off-the-shelf 802.11 equipment. He is aiming for a July 4th, 2006 first coast-to-coast ping. This project appears to be totally volunteer based, With no other stated reason than fun with pringle cans and bad weather, and do it just to do it. Can this be done? What real world applications does this have?"

The Government is, frankly, outright hostile to many forms of free expression, and some basic civil rights we've come to take for granted (abortion rights, for starters, never mind the Bill of Rights).
This project may teach valuable lessons about using open standards to form a non-owned, alternative internet backbone.

What is the dbi gain on the pringles can? Even if it was over 16 dbi you could always use a 30 milliwatt card. Then you could have up to a 24 dbi gain on your antenna. I seriously doubt a pringles can offers more than 24 dbi gain.

Just because your social/political grouping sees it as a basic part of 'life' does not mean that society in general sees it as such, and I would hazard to guess that if it was such an entrenched social defacto standard as you suggest then no government would be concerned at allowing it.
But basically, there is no overwhelming social majority on one side or the other. There are big camps on both sides, with some valid concerns and some crap too. In the middle is the large group who don't consider abortion even an issue until it directly involves their lives, and could most likely not give an honest choice either way.

Fair enough. Although fiber throws the bits around better.
If he can succeed, the long-term implications are fantastic. Internet will become too cheap to meter. Inexpensive laser and other types of LOS relays will join windmills and silos as familiar rural landmarks. AOL and Time-Warner can eat all of America's shorts. There is nothing to say the same economic forces that may eventually make proprietary software obsolete can't make proprietary networks obsolete too.
Yeah. And if everyone laid fiber to their neighbor's houses and got routers for it, the same thing could happen. That'd be really cool, too, and probably about as cheap. But it's not gonna happen anytime soon.
The hard part about free wireless has always been the "upstream". If this guy can get a viable continent spanning link, it may go down in history just like the link between... what was it... Duke and UNC? You know, the one that started the internet in the first place. Let's see... we have internet, internet 2, and now internet 3. I can't wait. I think Internet 3 could eventually replace internet 1 and make internet 2 jelous.
There's a ping-time issue. The cost of receiving and retransmitting those packets is non-trivial, both in time and in energy, especially if you use WEP. Count on pinging across the network to take minutes. Like I said, laying fiber would be much cooler for free internet. But it's just as not-gonna-happen.

I think the only way it will happen is if some ISP/Telco thinks it's a good marketing idea. And in that case they'll probably run it along major highways through those desolate areas.
Advert example: Two Verizon trucks driving towards each other down a desolate road in the middle of the US. Each planting the very last (golden spike) wireless connection on each side. Shows family driving through the middle of nowhere USA with a kid in the backseat surfing the web - "Drive coast to coast wirelessly, Only with Verizon."

Am I the only one that thinks that is an INCREDIBLY pessimistic estimation? There are plenty of wireless links that go several miles at a time. Let's assume we have a router every 5 miles, then we'd have better speed than if we'd gone to their limits, and if one failed, there would still be a link, albeit quite a bit slower...
So, instead of 30,000 routers, let's try 600 routers... And more than that, let's not forget that much of the US is densely populated enough that the 802.11 cards of end-users would function as routers, so even less would be needed.
How incredibly crappy are these routers of which you speak? They are solid-state devices, there is very little to go wrong with them. At best, I'd say dozens per year, not every day.
If by "serious" you mean "non-existant"... There are "Call Boxes" all along interstates. Each one has a great deal of electronics, and a solar pannel on top. I haven't heard of a single one being vandalized, nor have I ever seen one that looked like it might have been.
In conclusion, you are either trolling, or you just have no idea what you are talking about.

If the target is "cheap distance", you would
think having everyone's computer make the furthest local phone call to another computer modem, would be farther reaching and more reliable. sure only 28Kbaud, but that's okay. (assume local phone calls are free)
Just need people with two phone lines and two modems and the right software. Or you could have the computer hangup and dial out to forward packets/receive packets from the other direction and
alternate back and forth! (if just one phone line)
Big enough buffers at each computer, would help deal with this extra latency....

Thanks for the stereotypical perspective on fly-over-country (where I live). Sorry to cause you an extra few hours of flight time between the coasts.
Actually, it's been done before - many times over. There are numerous transcontinental microwave networks. Many are now dormant or retired - such as the AT&T Long Lines and its radio relay routes.
By talking 802.11b, this simply is going to be ugly. 600 router hops from coast-to-coast? No central design/administration? Trans-continental networks aren't like open source software projects

You could do something like in a limited fashion on the east coast, but not across the country.

A couple of people have mentioned transiting the Rockies. Not a good idea. Cellular systems don't do it. Living in Western KS, I've found that Cellular systems do not enjoy a two-way flow the length of I-70.
Eastern CO is supported from Western KS, via I-70. In KS, Salina sits at the top of a "T," where I-70 meets I-35. Head South, and I-35 turns into I-45. You get to Houston (which I-10 passes through). Western CO just doesn't have much coverage.
Then there's TX. Assuming you could get solid coverage to Kerville (a little West of San Antonio), it is a _long_ , empty haul to El Paso (ok, you have Junction, Sonora, Fort Stockton, etc). There just aren't that many people in West TX, till you get to El Paso.
Next up, NM, AZ, etc. Hot hot hot. Then, cold cold cold. Not a good environment for unprotected electronic gear. Going to need plenty of local Alternative Energy sources as well.
I know there are plenty of other state-level, middle-of-nowhere link-up issues. I'm just talking about the one's I know something about.
At a minimum, it is going to take the use of the Interstate Highway system (for communication equipment to be set up, and allow easy access to be repaired), and guys with their HAM radio tickets (at least Technician class) to be able to legally opperate equipment with enough grunt. Repeaters don't require call sign ID at regular intervals, I think.
Line-Of-Sight is about 9.2 miles, at Sea Level (IIRC).
Potentially a pretty neat hack.
