While I appreciate the fact that Your time is valuable, all of us here make mistakes?, And I thought I would point that out:)

I too am pushed for time, as are other readers of these forums. That's why it's important to make accurate posts so that some greater number of readers aren't confused or forced to again read the original article.
When you think you are pointing out someone else's mistake, as viperm was, it's that much more important to take extra effort to see that you are correct and you aren't wasting other folk's time.

OK Jesus, I am sure that You have never made a mistake?:D
A lot of us are pushed for time?. I am one such person. Perhaps the person in question just skimmed the article and missed the "AMP" part?
Why don't we crucify him?;)

The limit for unlicensed 2.4 is 36dbm out the antenna for point to multi-point links.
For point to point links, you can make that quite a bit higher. You start with 30 dbm at the radio and a 6 dbi antenna to get the 36dbm being transmitted. However, in point to point, you can add 3 dbi of gain to the antenna for each one dbm you take off the radio. so if you set the radio to transmit at 24dbm you can add 18 db to the antenna and use a 24 dbi grid, giving you an eirp of 48 dbm.(i am assuming no cable or connector loss between the radio and antenna for simplicity). |

I think it's great, but did they do it legally? I seem to remember there is a radiated power limit...meaning that there is a limit to not only the xmitter power but also the transmit antenna gain. You can get enough gain in a dish or a phased Yagi array that you are required to reduce xmt power to stay legal.

This article says they DID use amplification???
Ben Corrado, Andy Meng, Justin Rigling and a fourth friend, Brandon Schamer (who didn't accompany them from Ohio), won the greatest distance achieved for an 802.11b network. The teens, two of them 18 years old and the other 19 years old, achieved 55.1 miles using homebrewed antennas on both ends along with amplification, exceeding last year's winner by 20 miles.
Read the next sentence, for crying out loud:
quote:
Then, when they established that record, they turned off their amplifiers and broke the record for an unamplified connection at the same distance.
