Defcon day 3 – 125 mile wi-fi shot

Team PAD has done it again. Running out of highway last year they were only able to get 55.1 miles. This year they made it all the way into Utah to do their record breaking shot. Congratulations guys!

If anybody is looking for Primestar or DirectTV dishes to do long links with, I’ve gotten two of them using freecycle.

    If you dont want one of the dishes I will take it off you hands for you. I would really like to make a dish antenna

  2. Groxx says:

    12 ms ping…
    and connecting to my neighbor to play games gets a ping of 80. How sad.

  3. ry says:

    thats a kickass wifi network.

  4. Urza9814 says:

    Jesus! 125 miles! I can’t get a good connection at 20 freakin’ feet! I sometimes hit 32ms just connecting from one end of my house to another!

  5. Polymira says:

    That’s what the WRT54G(S) is for (wds is the shizzle)

    I hadn’t thought of looking on freecycle for a dish though, thanks for the idea

    Does anyone know how I can do rhis aside from the dish which I just got

    Ask any (small) retailer of Primestar and DirectTV dishes for one, generally most of them have a pile of unused ones. A friend of mine has the floor of a small room covered, and Radio Shack in town has a small shed full. Their difficult to throw away, so I’m sure they’d give you a free one just to get rid of it. (And yes, they work great for dish antenna’s! Mine’s about 23dBi)

    That’s great for a LOS link, but what is the record for a NLOS link?

    Anyone have any links to where I can find info on 600’+ NLOS links?

  9. Kazuko says:

    125 is very good for wi-fi imo. I wonder if I can use it with my nintendo ds to play against people with….?

  10. Chris says:

    screw wireless, wired is the way to go. faster, more reliable, and you dont have to worry about people leeching your wifi!

  11. m4ff3w says:

    Chris, do you have 125 miles of Cat5 laying around?

    And I really don’t think that with such directional antennas you have to worry about anyone leaching.

    …and in traditional Defcon style, it appears the winner’s website is DOA. Another site with minimal info:

  13. Travis Beard says:

    Isnt Llne fo sight only like 32 miles? Thats the figure we use in the military.

  14. m4ff3w says:

    Travis, one of them on top of a mountian.

  15. ed3 says:

    32mi near sea level. Mt. Potosi is around 8000ft above sea level. Utah Hill is around 2000ft… Line of sight is around 200mi at those heights.

  16. T38 says:

    m4ff3w, seems to me that if you’re in the line of sight, you *could* leach the signal. Though, I’ll grant that would have to know it was there if you were going to intercept a tightly focused signal. Still, you know what they say about security through obscurity :)

    I finally edited and posted the video from the DEFCON WiFI Shootout event along put some photos and topographical information up on the web.

    Here they are:

    It was great fun watching the team set this record!
