First Free Wireless Link Between Europe And Africa 143

Posted by timothy from the one-swallow's-flight dept.
Paul Bawon writes "A company called PSAND have just installed a wireless link between Tarifa in Spain and Tangiers in Morocco, thus linking the African and European continents together with a free wireless link. The link went across the Straits of Gibraltar with a total distance of 32 km over the sea. Images can be found here and notes from the work can be found here."

      A small correction: I think that the images are of the apparatus used for the wireless connection, not images of the medium itself. For wireless, the medium would probably be air, and I do not think that an image of air would be that interesting:) LOL

      PS. I cannot get to the images right now. I think that the links are broken, because the browser is blocking when I click on the "Images can be found here" link, so I could not confirm that the images really show the apparatus.

      There is a huge loop of fiber going all the way around Africa that was put there during the dotcom boom by a company called Africa One. Apparently it is mostly dark, because no one can pay to use it:

      See here for a large pic [ucl.ac.uk].

      More info:
      Wired News [wired.com]
      Lucent [lucent.com]
      Some interview [emeagwali.com]

      So this is interesting for wireless sake, but not interesting for the sake of Internet connectivity in Africa. This fiber loop needs to be put to use to enable cheap Internet in Africa. Many Internet connections are still done by satellite, which is expensive and slow.
      • How about cheap food in Africa, before cheap internet? After all, many people in Africa are hungry, few are wondering what geeks think about star trek.
        • How about cheap food in Africa, before cheap internet? After all, many people in Africa are hungry, few are wondering what geeks think about star trek.

          Agreed, but it's better to teach a man how to fish than to give him the fish.
          Getting Africa online will increase its economy in a way you can't imagine. Sending food and money (for food and weapons) to a Third World country hasn't been much of a help over the last couple of decades, it's time to get these countries on their own feet.
          • When you're going to be dead in 3 days from starvation, trickle-down economics means jack. Sure, teaching someone to fish is better than feeding them, but again, if they're on the brink of death, Fishing 101 isn't going to help.

            Getting Africa online won't do anything for the starvation. Opressive governments and corrupt beaurocrats means any aid or money going to Africa is quickly syphoned off into their pockets. Giving them free porn while they do it isn't helping the millions of Africans slowly dying

          • You can only do an unprovoked regime-change on a soverign country if that country has significant oil deposits.
          • And internet access would help that how? Bearing in mind most people don't even have mains electricity, let alone a computer. Sheesh. People are dying now. Internet isn't going to help anyone out of that.
        • Cheap food in Africa is a non-trivial political problem. And one could argue that the best way to help people in Zimbabwe to get cheap food is to help open up discourse in the country.
          • And one could argue the best way to help people in Zimbabwe is to jump around on one leg shouting "I am the food master!" - it doesn't mean it would work. Political change doesn't instantly give food to people, and it doesn't happen in an instant. People are dying now. Cheap pr0n and access to hotmail aren't going to feed them.
      • Could you not find any links to articles which said things like "Africa ONE has completed..."? Because all of your "More info" links say things like "The Africa ONE project will create...". I could find no proof that it actually was ever completed, or even started, so the fiber is possibly very dark indeed.

        I was able to find links about this from 1995 [att.com] 1998 [globaltelephony.com] 1999 [lucent.com]. So it's not like this was necessarily imminent just because Wired was writing about it.

        Apparently it is mostly dark, because no one can pay to use it

        Most fiber in a bundle is SUPPOSED to be dark at this point. To lay less than a bunch more than you initially need is incredibly pound-foolish in the long run - and even the short run.

        Nearly all the cost of a fiber run is laying the cable - whether digging a trench around a continent or paying it out on the ocean floor. The incremental cost of adding fibers to the bundle, as a percentage of the cost of laying the bundle, is miniscule.

        The amount of data that can be carried by a single pair of fibers is enormous. So one pair can probably handle all you can sell in the first few years. And even in that one pair, half of it is proably spare - reserved for routing around breaks by slinging the data the other way around the loop. So if you look at the contacted bandwidth versus the fiber's bandwidth, even your one "lit" fiber looks "half-dark".

        But you don't just lay a pair of fibers. You need spares even initially. (Else what do you do if a fiber breaks? Dig/dredge up the run to replace it? Or use the spare fiber.) So now even with one set of spares you've doubled your capacity and not used any of the "extra". 75% "dark" and looking worse.

        But what happens a couple years down the road when your capacity is all contracted out and you need more? If you laid down extra fibers you just light 'em up. If you didn't, you need to DIG ANOTHER TRENCH AROUND THE CONTNENT to lay more.

        So of COURSE you spent a few percent extra, and laid maybe 20 or 50 or 100 times as many fibers as you initially need. You don't EVER want to dig that trench again.

        But do you light 'em up now? Of COURSE not! The incremental cost of LAYING extra fibers is tiny. But the incremental cost of LIGHTING more is nearly the same as lighting the first ones. And every year the equipment gets cheaper and can push more data through the fibers (though not enough more to eliminate the need to light more fibers eventually). The longer you wait to light them, the more bandwidth bang for your buck - so you delay deploying the BOXES as long as possible.

        Thus, if your planners had any savvy, nearly ALL your fibers are dark, and will be for decades.

        But some clueless "analysts" assume that the cost of laying fiber is in direct proportion to the amount of fiber laid. So they look at how much got laid, and how much is currently lit. And they trumpet the "dark fiber" "problem" to the world, convincing investers that the far-seeing planners who laid it have wasted their investors' money. Oh HORRORS!

        In fact, the people (if any) who wasted their investors' money (at least in the fiber laying process) are the ones who spent nearly as much to only lay enough fibers to handle the immediate needs.

        The collapse of the long-haul market was due mainly to the fact that EVERYBODY laid fibers, assuming they could each get a big chunk of the market. Too many suppliers led to a price war that took most of 'em down.

        But the "dark fiber problem" scare stories provided a bit extra push, sucking needed next-stage investment out of some companies that might have made it otherwise and leading to their demise.

        As a result of this scaremongering we'll get more consolidation, and higher prices, than we otherwise would gotten without their panic.

    This one is not a distance record, but it did span continents and is an interesting article. Here's an article [oreillynet.com] from last year about longer distances, albeit with higher power gear.

    The ham radio record for 2.4 GHz is a lot longer, but it's a great start. Here are some results [ham.se] from Region 1, Europe, including Earth-Moon-Earth.
