More Antennas, Faster Wireless

rouge86 writes "The New Scientist has a story on how researchers broke the network speed record using a wireless network and multiple antennas. They plan to use the demonstration to show how powerful multiple antennas can be. Applications include power saving on mobile phones and reducing interference."

Great engineering

[Rosco P. Coltrane]

For those who don't care about reading the entire article, the crux of it is:

Recombining smaller signals in real time, however, requires considerable computing power. So the Siemens team developed new computer algorithms in order to send more data using existing hardware.

In short: programmers managed to push existing hardware with a more efficient code. That's called hacking, albeit with a serious look, and I like that!

this is the same post, as the dec 08 slashdot post here: http://slashdot.org/article.pl?sid=04/12/08/022625 0&from=rss/

Atcually it's not; that was talking about the record they broke. This article is talking about how the actually broke it :)

Re:More antennas = better?

[Anonymous Coward]

Having more antennas allows you to do interesting and useful things such as cancelling out multipath and multiuser interference. This has been studied for a long time now.

The three blades give a better shave since when you take one stroke, it takes three. Having four blades, however, is getting a little ridiculous.

Interference

Reducing interference.

And increasing it for the neighbour, unless he also has multiple antennas.
Wich gets us back to the start, only with even more interference...
