Wi-Fi Ranges

    So, I was at the local sandwich shop last night, and I noticed I was able to
    pick up a signal from a local T-Mobile hotspot, which I have an account
    with. It was only one bar out of five. But I was able to connect to it and
    surf the web without any problems.

    I then looked up the hotspots in the area, and I saw that the closest one
    was a Fed-Ex/Kinkos about 2-3 blocks away. Measuring it on the map, I
    estimate it to be at least 800 feet from where I was.

    Is that normal for wi-fi routers to have such a large range? That seems a
    bit far to be picking up a wi-fi signal. The router was a little uphill from
    me, though not a very steep hill.

    For those type of deployments, they set it up it work within the
    building. So it will likely get out into the parking lot also.
    That's all the need to care about.

    Will it go farther? Sure. Will it be a reliable link? Most likely
    not. I installed a Linksys WRT54G and it was usable over a thousand
    feet away which surprised me.

    A true case of "You mileage, err...footage may very".

    Doing testing with a couple of Cisco APs and high gain omnidirectional
    aerials we've had them working over several hundred meters , and even
    further with directional ones but that's on open ground. In a built up
    environment it's unusal to get anywhere near that.

    It's possible there was another hot spot not shown on your map

    No, the chances of there being another hotspot are very slim, as there's
    only a few types of business that have T-Mobile (Starbucks, Kinkos, some
    hotels and airports -- that's about it). This wasn't a random hotspot. It
    was a T-Mobile hotspot, and there are only a discreet set of them.

    As for open ground, though, the place where I was down the street (to the
    south) and a little west of where the hotspot was. In between (the northwest
    corner of the intersection where I was at) was open. Thus, between me and
    the hotspot, there were no buildings. I'm sure that was it.

    The world record for unamplified WiFi using off-the-shelf Linksys APs and
    very large omnidirectional antennas is, I believe, over 280 kms.

    The record using a home made directional antenna at a hackers convention
    in Las Vegas a couple of years ago was 51 miles. Although I never
    learned if they were on top of a mountain or not. I bet they were.

    That's cool. But I doubt the local kinko's had any sophisticated antennae.
    Still, I think the fact that there were no buildings between us and there
    was a little downhill helped. I think the fact that there was a slight
    breeze from the direction of the Kinko's to where I was helped as well.*

    *Before someone jumps in here: yes, that was a joke.

    That's old hat. It was broken in Venezula the next year. The one you linked
    to was 200km, the Venezuelan record is 279km using just a pair of Linksys


    That was in '06. I've just Googled the guy who did it (Ermanno Pietrosemoli)
    and find that my info is old, his record got broken, so he set a new one in
    June this year. 382km, or 238 miles for you late adopters.

    It is conventional in most newsgroups to post your reply at the bottom of
    the previous, this is called bottom posting. You have been putting your
    reply at the top, which is known as top-posting. Top-posting is the
    convention in emails because if you are replying to an email then the
    recipient should have a grasp on what went before. When posting to
    newsgroups others may not have seen your original post so its useful to have
    the previous text available and visible first.
    A: Because it messes up the order in which people normally read text.

    Sadly, I haven't fixed this one. Its worth having a read of the links that
    CBFalconer provided.

    It is quite possible one of these other businesses had put a
    repeater on their roof so they could enjoy using their
    account inside without having to pay for on-site service.

    The only way you could more reliably know for certain is to
    take a wifi locator, signal strength meter back down there
    and canvas the area looking for more spots not on maps.

    It is certainly possible for signals to go 800 feet outside,
    line of sight, but more surprising if you're inside the
    sandwich shop, even moreso to maintain connection with a
    laptop and do that in a shop where there might be a kitchen
    with microwaves.

    And how do you know that for sure? It's not all that hard to spoof a
    hotspot. Use the same SSID, capture the HTTP traffic and fake the login
    handling. Then use the stolen information to hack the real service.

    So, Neil
    I think you were very successful getting responses for a stupid
    question, and stretching it out by your responses.

    For a troll you did very well.

    I take it you don't have any friends to hang out with during winter
    break from school.
