World's Longest Wi-Fi Connection
axonis writes "The Swedish Space Corporation (SSC) announced today that they have transmitted information via a broadband wireless link over a distance of 310km. They believe that this is the longest distance achieved using wireless connectivity. Alvarion (BreezeCom) is also the original consultant to Ericsson for BlueTooth technology"
Kilobytes per second?
'Broadband' implies a certain connection speed(?)
Physics is like sex: sure, it may give some practical results, but that's not why we do it.
In the US we're only allowed to have a 1 watt antenna. This antenna is a 6 watt antenna.
Is it me, or is that just a TAD low? I mean, it seems perfectly logical to me that increasing signal power decreases signal loss and would therefore increase throughput. So why are they using something so weak, particularly over such a long distance?

More than that, this does away with the need of intermediate hardware for long distances.
A big boon for use in desolate and (naturally)unfriendly environs.
Very cool indeed. That is infact something that would be immensely useful in places like this for these people.
Actually Ham radio blew away this lame 310Km distance in the 144mhz band years ago... 384,400KM times 2 (that's the distance to that funny big rock in the sky and back) sending packet data at 300 bps.
But this is not about just transmitting data this is using OFF THE SHELF 802.11 equipment and getting it to work that insane distance.
Do not look at laser with remaining good eye.
How many millions of kilometers away are the Voyager probes right now?
It ain't broadband, but data has been sent over their wireless connection.
If you not going to use a standard you not even close to the longest wireless link. Anyone remember contacting voyager a couple months back. Correct me if I am wrong but they are not running a wire all the way out there are they?

First a correction:
:)
This was not a weather balloon, but a stratospheric scientific balloon: these can carry payloads up to 8000lbs (on the extreme upper limit) and can keep them up for weeks (the current record is 31 days)
Now my question: what was the link they were using? What was the bit rate? What what was the bit loss rate? Were they shipping TCP/IP, or was it special purpose format. If the former, I'm intriged - how nice it would be to log into one's balloon borne stratospheric telescope and fix those lingering bugs (bugs? what bugs? never...)! If the latter... well, at this very moment I am monitoring data from our stratospheric balloon instrument which is currently at -80.5 lat, and -78.2 lon and an altitude of 31.2km (ie, over the antarctic plateau). We're only getting a 6kbit link (through the TDRSS sattelite) now that we are out of line of sight, but -80.5 lat, -78.2 lon is a *long* way from here in Toronto
Wireless networking might just be a multiple violation of the law in Egypt.Details here and here.
