New Mobile Network Technology at 2.5 GB/Second?

Posted by ryuzaki0 on from the yet-another-claim-and-i-keep-hoping dept.

craig.hathaway writes to tell us that Japan's NTT DoCoMo claims to have a prototype wireless network capable of speeds up to 2.5 GB per second. From the article: "MIMO (multiple input, multiple output) uses multiple antennas to send and receive data, as well as specific coding that scrambles and unscrambles the signals produced by those antennas (see "Faster, Farther Wi-Fi"). A base station that uses MIMO technology has multiple antennas that simultaneously receive and send data to and from wireless devices. Unlike base stations with a single antenna, those with MIMO use the multiple antennas to create a number of intertwining channels through which data moves. The jumbled signals are untangled by a 'signal processing' that sorts through the bits."

    I see this as a bigger scale form of a bit torrent, wouldent you receive several of the same package for different channels?

    I could see this making mobile computing something more then it is, I know in the high end range of phones there are small computers basically in the users pocket, but this might allow it to become more of a standard and the phones we see as high priced will one day become the one we get free at sign up. Good luck to them I say

    802.11(pre)N and Super Duper Ultra G routers have had MIMO for some time now. I guess this is new because it was rolled out on a larger scale?

    "fast enough to download a DVD movie in between 7.5 and 10 seconds -- to a mobile device traveling at 20 kilometers per hour."

    Hopefully, at some point they will develop a technology that will let you download movies without running 50 metres.

  4. Serial vs. Parallel by mikeage · · Score: 3, Interesting

    Excuse my ignorance, but isn't this simply a case of converting what used to be a serial protocol into a parallel version?

    Are we going to see a serial version come back in 5 years, which will be much faster due to the lack of syncronization overhead required?
