    Or, if you want to be really crafty, just get together a caravan of boats and large lake or ocean, and do it out there.
    Anyone object to me bringing out the boat to do a little networking? Yes, I know I created the post, But in reality I don't feel that doing it on a lake, or ocean or whatever is ANY safer than the open road. Doesn't matter, idea has been dropped long ago.

    In using a high-gain- amplified-omni-directional antenna, connection broke at around 750 ft i am estimating, in less than perfect traffic. Signal had to go through several cars. I know 750 ft is not much but it sure is better than the 50 feet your saying is nessessary to conduct this project.
    You do realize that driving the average speed limit down to defcon, (which for all intents and purposes we'll assume is roughly 75-95 mph :) ) a 750ft distance becomes quite short when the driver in front of you has to slam on their brakes for any reason? and, let's be honest, we know you'll try to get the cars closer than that anyway. Simply put, just enjoy the open road. No one needs an assclown to crash into them from the other lane just because the person looked down and to troubleshoot why their wifi wasnt working. If you are that intent on doing it, get together a caravan of people who will be driving around, at a safe/slow speed with the traveling ad-hoc being the only thing in mind, not while your actually on a trip or trying to get somewhere. Or, if you want to be really crafty, just get together a caravan of boats and large lake or ocean, and do it out there.

    and yes I realize the last post to this thread was a while back, I just happened to browse over it and it got me in a ranting mood. :D

    Damn you and your GPRS ... damn you.

    The only time I've had a box in the passenger seat ..aka passenger table ;) ... is when I had something like mappoint on it and used it _infrequently_ at noted 'safe points' (red traffic lights, railroad crossings, parking lots) when I could keep my ass from getting lost. Even if you're driving out in the middle of nowhere, and you take just one second to glance over and make sure you're on the correct road.. around the bend could, hypothetically, be a surprise intersection that you have to skid through strategically McGyver style to avoid traffic from 3 directions... My wardriving box is almost always in the back seat behind me... which is why sound can be useful; pump it through your car speakers and have a blast when networks bump along to metal mmmmm

    ... now you've made me horny.. sigh

    Personally, I don't see a problem with passengers using laptops. The wifi thing is a bad idea, though. We drove straight through to Vegas from San Antonio, and it was a longass drive through a lot of monotonous desert. Hell, half the drive was just getting out of Texas! When we weren't driving or sleeping, we were on 3g. Surfing quietly seems like a much better idea than pestering the driver.

    Or get a co-pilot...

    see the law about the gps i am interested in, cause I have my handheld one mounted with suction cups on my window, just curious what that would constitute as.

    I think this could actually be pulled off safely, under specific conditions. Each car would need an AP with a high gain antenna in the front and a high gain antenna pointed straight back (ie.. lucent wavepoint duals)... possibley even an rx/tx amp in the mix depending how you designed it... the key would not be exceeding fcc limits but getting damned close. Each car would serve to bridge on a single network.. this would require trying to maintain a pretty strict formation. Pulling out of formation (ie dealing with regular highway traffic such as passing etc) would temporarily break the network.

    With a whole lot of planning, money, and know-how.. it _could_ be done... but... why? You would also have to leave out the person in the front passenger seat per many state laws like the California one... even if it isn't specifically a state law, it certainly takes away much credibility if a cop pulls you over for wreckless driving. Best solution.. go HAM.

    ... just a little service announcement from an Oregonian that will be thoroughly pissed if you deface the WARDRV plate with stupidity.

    Exact Route:)

    So far:

    1 Black 2003 Suburban (Licence: WARDRV)
    1 Yellow 2002 Xterra (License: WIFI)

    Allright

    Well-spoken pieces of advice my friends.

    I have done alittle testing with is WTN and have come out with the following:

    In using a high-gain- amplified-omni-directional antenna, connection broke at around 750 ft i am estimating, in less than perfect traffic. Signal had to go through several cars. I know 750 ft is not much but it sure is better than the 50 feet your saying is nessessary to conduct this project. But everyones concerns have put my idea on the backburner, I tend to listen to comrades and respect all of you for your insights.

    cause If when I am driving down I detect an AP and all of assudden get hit by some fuckers on the laptops, I will be out for blood

    This was mentioned last year, it isnt a good idea, you can wait like the 6 hours it takes to make that drive. I was thinking about this to, and how nifty it might be, but as pointed out, the cars would start to bunch up, and of course, you would be distracted by the convo, or perhaps keeping everyone within range, not to mention how much I am sure the cops wouldnt like around 5 people in a car with there laptops open....not a good thing....just save it, check out cb radios or frs if you must stay in contact, cause If when I am driving down I detect an AP and all of assudden get hit by some fuckers on the laptops, I will be out for blood.

    OK. Let's put it this way:

    The lead vehicle is housing the host AP. We'll say the average length of a vehicle is 15', which is probably a bit short of the truth but convenient for my argument and actually advantageous to yours.

    Assuming the vehicles are travelling 50' apart, that means that there's a total of 15 + 50 = 65' per vehicle and following distance.

    In absolutely optimal conditions, an 802.11b AP can be expected to have an effectgive radius of around 1500'. 1500 / 65 = 23 and change, which represents the total number of cars that could - at best - be expected to be within reception range.

    Access points are far better radiators than most wireless cards. People in the cars tailing the AP lose signal back to the AP, so they bunch up to get closer to it. THIS IS WHERE *ONE* OF THE PROBLEMS IS. Not to mention that if you're only 50' away from the car in front of you at 70mph (the legal maximum in CA, and you don't speed), you're still about 550' short of the prescribed safe following distance, or over one-tenth of a mile.

    So unless you only intend to have two or three cars participating in this idiotic little escapade at nothing other than the safe following distance - you're still doing something dangerous, stupid, and stupid because it's dangerous.

    It is to teach others in the caravan (that have yet to see it work in person) how it is done, and used.
    You're right. This is why every '77 Pinto comes equipped with Wi-Fi as standard. How silly of me to be ignorant of the motor industry's mad rush to equip everyone with it.


    The spread of information, isn't that what we are all here for?
    You can spread information all you want, but if you're likely to represent a danger to others while doing so, don't be surprised when people step forward and tell you to find another way of doing what you're proposing. Welcome to being part of a community. Just because my neighbour can get drunk and play with guns on his front lawn doesn't mean I won't shoot him myself if he may injure or kill me or others.

    I will be sure to.

    You make an number of inane points. First off, you dont have to be speeding to get in a wreck, so while you dont drive 120 it does not make what you are doing safe. According to the NCSA speeding only contributes to 31% of all fatal accidents. So even though you guys are all driving 55mph, there is still a signifigant risk there.

    Your second point is your logic behind your 'It is to teach others in the caravan (that have yet to see it work in person) how it is done, and used. The spread of information, isn't that what we are all here for? ' logic. This is just dumb. Lets say you wanted to learn how to shoot a rifle, by your logic its just as fine to teach you by hanging out of a moving car than down at the rifle range. Yes we're all here to learn things, but there is a difference between setting up an ad-hoc wireless network poolside at the Alexis Park and doing it in the back of an 86 Mustang.

    Please post your caravan route well in advance so I can make sure to avoid it at all costs.
