WiFi transmitted over 382 km

[Jimmy 2004]

You might be pleased with your new wireless equipment that can transmit signals as far as a few houses down the street, but Ermanno Pietrosemoli (president of the Escuela Latinoamerica de Redes, which translates as networking school of Latin America) has managed to establish a WiFi link between two computers placed 382 km apart - that's about 238 miles. Using this connection, Pietrosemoli managed to achieve transfer rates of about 3 megabits per second, which is quite impressive considering the distance involved. This figure represents a new record for a WiFi connection, and was achieved using a combination of technology from Intel and some "off-the-shelf" parts, set up to transfer data to a specific point rather than in all directions. The previous record was held by a group of Swedish scientists that managed to create a WiFi connection between a hot air balloon and an Earth-bound station 310 km apart, so this exceeds that by almost 25%.

That is just plain awesome. I cant wait till they get the speeds up at that distance. Talk about mooching hot spots <G>

Hmmm, 382km... shouldn't the curvature of the earth kick in at a distance like that?
Sadly they don't seem to mention what the local conditions were, nor whether they used 802.11b/g (2,4 GHz) or 802.11a (5 GHz)

Can't to something like that in my country. Maximum for WiFi is 100mW, so a no-go for distances like that.

Very nice

well we all knew this was coming because we all know that someday there will be a universal wifi signal and it will be everywhere all the time and very very fast.

Hurray for globalization!

Great for them! Still just a little shy of the distances here:

Of course its got just a bit more power....

Im sure I heard something about wimax? Think thats what its called and thats ment to be the next gen of wifi and its ment to transmit over massive distances, which is pretty cool!

Interesting read

I can see lights at night over a million years old. So nah.



But good find.

Who says they have to know about that signal amplifier you want to run? lol

The maximum for CB radios in the US is 5W, but that didn't stop me from running a 12W radio with a 250W linear boot. lol

^Haha, nice
