    wireless networking (not in car)

    how far can you get with a wifi network? i need to network like 600yards away...

    i got broad band.. but my friend whon lives like just down the road cant cus he is on a diff exchange, i just wondered how far wifi would go. also i guess it should be noted i live in the country and there woulndt be any real inteferance.

    also what kinda connection speeds could i expect?

    thanks,

    tom.

    hm normaly its range isabout 300meters at the field (no walls or trees in between) but if you use a satelite dash and an external antenna that point to each other it maybe could even beat that distance

    Its all dependant on how you set it up. If you get a high gain external antenna and mount it on your roof (or somewhere high up giving the best 'line of sight' to your mates house) then you should get a decent signal strength. It works both ways so make sure your mate has something similar.
    The thing with frequencies used with WiFi (2.4GHz) is that they are more prone to being reflected from objects rather than go through them. So having something as simple as a thin wall between you and your mate could severly reduce signal strength. The aim is to have as much signal leaving your WiFi (and his) as possible so that by the time it reaches your mate (or you) the gain is still strong enough to be of use.

    EDIT: Also, this may be obvious, but make sure you keep both your antenna's vertical.

    look into a Yagi antenna, Ive heard with the proper setup, they can go up to a mile line of site with full signal strength, 600 yards is only like 1800 feet. so you should be good. theres info out there on building your own hi gain antennas also.

    ohhh I completely forgot about Yagi. Yes that would be a great idea. Dont bother building your own unless you dont mind failing a couple of times first. Getting the length of each rod would be hard with such a high frequency. Cheaper just to buy 2 along with a motorised base and your in business

    If that doesn't work out, you can always put a repeater (ie. just another access point) somewhere between the two points.

    you can build a waveguide antenna, affectionately called a cantenna online for about $4 or $5, just an n connector mounted in the right place, with a wire element of the right length, and people are getting anywhere from 1-10 miles from these, depending on the hardware you are using (quality of cards, links, and whether or not you use an amp in the setup)


    http://www.turnpoint.net/wireless/cantennahowto.html

    this site tells you how to build one, and has a wonderful calculator to tell you exactly where to mount the element in your can.

    much cheaper, and worth trying if you are considering dropping a bunch of $ on a set of yagis....
