Siemens Develops 1 gbit/sec Wireless Link 191

jonknee writes "Siemens has developed mobile wireless technology with transfer rates as high as 1 gigbit per second. This blows the doors off of '3G' technology, or EV-DO (the high-speed data technology used by Verizon Wireless and soon by Sprint PCS). Not all the specs are out yet (more info is expected early next year), but it uses three transmitting and four receiving antennas. With any luck the phone in your pocket will have a gigabit link by the year 2015."

    How can it be possible to get a cellular data service that's faster than a WiFi LAN?

    Also, if this is for real, surely this has implications for the many planned city-wide wifi grids (Wi-Max, etc) and other mobile broadband solutions, as it could make them obsolete very quickly.

      Multiple antennas.. sounds like a variant of BLAST:

      They claim >20bps/Hz by making lemonade out of multipath's lemon.
    • If this is a free space system, they might have to compensate for the higher speeds with stronger signals (or live with shorter distances), shannon's law and all - of course we haven't approached those limits yet (I think), so it might be doable.
    • RTA. They're multiplexing; using several different channels to allow many different streams of data simultaneously. Yeah, it makes it a bit more complicated and error prone in the protocol specs, but it means a faster signal. And yes, to some degree, it will make other mobile broadband solutions obsolete, that is until they spec out the next generation of wireless to use similar methods. Remember, this is something that's going to be rolled out 10 years from now. I'm sure wifi is going to get a lot better i

        WiMAX (802.11g) - in the appropriate codec for this comparison - gets 70 Mbps out of a 14 MHz channel (a little wider than two TV channels). This system claims 1 Gbps out of a 100 MHz channel and spatial diversity. That's twice the bps/cps, which is about right for using 3-

By using multiple antennas, and using the multipath time difference on the signal, they are able to discriminate signals in the same band of frequecies based upon the physical location of the antennas.

    I'm very skeptical of the viability of this for a consumer market and I'm pretty certain I can get 3 randomly selected users to agree with me. Firstly, the large amounts of antennas would suggest this can't make it outside of a research lab. Secondly, you can't even get 54Mbps without paying thousands of dollars per month WITH WIRES. Maybe they could transmit this much between the tower with a single client (scalability anyone?) but if our current wired infrastructure has trouble managing 100 Mbps then what good will that link be?

    Anyway, my point here is that maybe you'll see a speed increase but don't expect anything in the real world faster than a wireless G setup anytime soon. It'd be damn cool though.

    That's 10b:Hz. I can't wait to hear about their novel encoding strategy.
  • This is a multiple-antenna technology, called MIMO for Multiple-Input-Multiple-Output. Instead of modeling the "medium" (electromagnetic spectrum) as a "box" taking a single signal as input and outputting a single signal, the medium is modelled as a matrix taking multiple signals on input and outputting multiple signals, on the same frequencies and at the same time.

    The capacity increase is *theoretically* limited by the max number of antennae in input or output: say there are N transmitters and N receivers
  • I want 128kbps. It shouldn't add more than 20-30 ms to a ping time. I want it anytime/anywhere. For a flat monthly fee, and don't count my minutes. I'd be happy to pay $75-$100/month for this. Much more and I probably wouldn't bite.

    I'm an indie developer, and do *alot* of remote sessions by SSH. Such service would free me (at last) from having to plan trips and vacations around which hotels provide DSL Internet service to its guests. (although, to be fair, it's much easier to find that now than it used to
  • In practice it would be difficult to get 1Gb/s in 100MHz of bandwidth. You need extremely good linearity in your link to get such a large constellation. To beat the noise figure problem you need either short distances or high transmit power. 1Gb/s links are being researched usning 60GHz carriers and a lot more bandwidth. 802.16 will more likely be used for 4G when low power solutions become available on the market.
  • Where the heck could they get that much spectrum space? For 1Gb/sec we'd need at least 100 to 300 Mhz of spectrum per user per cell. There just ain't that much spectrum available anywhere below 6GHz. Eventually when the current analog TV channels go away that will free up some space but not enough.
  • Heh. I wonder just how many different bands there are, and how many wardrivers scanning them...?
  • So what happens when you accidently cross the link between 2 receivers?

    Does your head blow up (buffer overflow!) or something?

  • Okay... three transmitting antennae and four receiving antennae... hmm...

    I'm trying to picture the kind of interferrence this causes with all three/four antennae doing spread spectrum and hopping around to find open channels to load up on.

    Also kinda wondering if this will drop like crazy when I heat up my muffin in the morning in the microwave. Hmm...

    I'm also wondering whether I would feel safe having this kind of device on my person... as it is, current celphones emit quite a bit of power.
