More Antennas, Faster Wireless

Posted by timothy on from the aim-high dept.

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."

  1. Wireless the wave of the future by drakethegreat · · Score: 1, Interesting

    This is just another sign that wireless is replacing wired networks around the world. I'm guessing sometime in the near future wireless will outnumber wired networks. I think that everyone can be excited about this.

      Where this will become really interesting is when there are enough wireless networks that they all link up. Once that happens, there won't be any need for ISPs as we know them - just get your wireless box and join the big mesh that's out there. No connection fees, no censorship - then we will have a truly free internet. Transatlantic etc. links will be slower, but I'm sure that's a problem we'll overcome.

  2. OFDM Has Been Around for a While by LuxuryYacht · · Score: 3, Interesting

    OFDM has been around for a while OFDM History

    It's nice to see more practical uses of it in wireless standards like WiFi IEEE 802.11a, 802.11g and in WiMax IEEE 802.16a.

    All this adds up to the death of the control by telco's in the last 100 yards of net connectivity. Go OFDM!!

  3. hmm.. wavelets? by Anonymous Coward · · Score: 3, Interesting

    Since the improvement was mainly a hack on the processing.. I'd guess that they went from some sort of fourier transform to wavelets.. wavelets have linear computational complexity (awesome) and don't have the interference problems that older signal processing algorithms have.

    ...for standardization as 802.11n

    Proposals were submitted back in August for 802.11n, and all proposals still in the running use MIMO+OFDM (the technique described here). Hardware supporting various prototypes is already around in a usable form.

    It seems unlikely that 3x4 MIMO will be around in the first wave, due to cost constraints - 2x3 (2 tx, 3 rx) is the most likely initial configuration.
