Ultrawideband Soon To Be Legal In Europe 109

ukhackster writes "ZDNet UK is reporting that ultrawideband will be legalized in Europe within 6 months, but with tougher controls than in America — the only place where it is legal now. Ultrawideband offers wireless connectivity at speeds up to 1Gbps, and is meant to supersede USB and clear our desks of wires. In Europe, fears that UWB might interfere with other technologies have kept it out of the market. Opening up the European market could give manufacturers a powerful incentive to push UWB." From the article: "[S]ources confirmed to ZDNet UK that the restrictions put forward by the EC would indeed be more rigorous than those imposed in the US, although they would not be so restrictive as to make it impossible for some global harmonization of UWB devices... It is understood that the committee decision to allow UWB was based on a far from unanimous majority, with some Scandinavian countries and France opposing the proposal."

    So, does "clear desks of wires" include life-time battery for my camera/cell phone/zune (:p), or we'll still have to have those gross wires (but won't admit it even to ourselves, of course).
    • "Wireless Desk Area Networking" is pointless until the desk incorporates a form of wireless recharger (e.g., inductive, or that dot arrangement thing, etc) and devices can be recharged via that mechanism. And that requires people to care about a few cables popping up behind the desk to their rechargers and peripherals. Note that a few ties can organise wires into looking quite tidy too.

      The problem is the "death of a million cuts" -- by the time you've tested for it, it's too late. Each UWB device slightly degrades the radio spectrum around it for more conventional narrowband devices. One or two or even a thousand such devices in a square mile might be OK -- but by the time you've got a hundred thousand or a million of these things deployed in an urban core, it's too late to back out.

      You can see the effect of progressive RF contamination by testing the range of (say) a CB rig in San Jose, California versus Tracy, California. Both have similar topography but vastly different levels of background RF noise in the 20-30 MHz band. (for what it's worth, a pair of car-mount Radio Schlock CB rigs with 1/4-wave antennae will work at up to about 35 miles in the California Central Valley, but only up to about 3 miles in Silicon Valley).

        That's an error in testing, not the technology. The instruments are sensitive enough to determine the noise change from a single unit. Toss in an amplifier to raise the level to that which it would be with a million people with it, and then check the interference again.

      FTA:

      It is understood that the committee decision to allow UWB was based on a far from unanimous majority, with some Scandinavian countries and France opposing the proposal. UWB opponents are mostly established band users who claim that high densities of UWB usage will raise the interference level enough to affect their existing and future services. However, tests in the US have not found any plausible scenarios where such interference is a significant factor.

      I believe there is some concern in Europe about interfering with GPS & GNSS equipment around airports. I believe a second GPS test in the US was done that showed it wasn't as bad as first thought, but I haven't read it.

        The initial tested used devices that were damn near on top of each other.

        I can show you a GPS unit failing when near a computer, or PocketPC under a similar configuration, with no other intentional radio signals present.

        I wouldn't want a large amount of UWB equipment on an airplane, but I wouldn't worry about my GPS unit not working because of equipment in use near me. The alternator in a car generates more interference.

    The question is whether UWB will actually be as useful as it's being touted. I certainly know that I have no need or desire to have a home AP that whose signal goes beyond 100 meters. I'm sure most of us won't be using it for that either.

    I can see a very practical use for this for quickly deploying an internet infrastructure under an emergency situation, as this would be perfect for creating relays to maintain connectivity to a distant area while covering a huge surface. I'm sure that as time goes on other more inventive applications will come to mind.

      I think you are confusing Ultra-wideband and WiMax.

      WiMax is like conventional 802.11 "WiFi," but optimized for higher data rates and much longer distances. It's like Wifi on 'roids, emphasis on coverage area and distance.

      UWB is different; it's a very short-range protocol for 'desktop' use. Basically, as a way to get devices that are near each other anyway, to communicate with each other without wires. Think of it as Bluetooth on 'roids, but hopefully without all the obnoxiousness.

      UWB would definitely not be good for creating point-to-point internet relays/backhaul, or any application that involved distances of more than a few feet. It uses way too much RF spectrum; the idea is that it transmits on a whole load of frequencies at once, but since the power is very low, it doesn't interfere with other things (too badly). This way you get ridiculous data rates, comparable to high-bandwidth wired protocols (so say UWB's promoters) but without having to have wires all over your desk. In a UWB-ed world, you wouldn't have to have a cable going from your scanner to your PC, because it could just pass the data wirelessly.

    Taking a peek behind my desktop PC, I see mostly wires for the following:

    2 VGA cables to my dual monitors
    2 Power cords to those monitors
    1 power cable for the PC
    1 RF antenna for my FM tuner
    1 Coax for my cable TV
    1 cord for USB mouse
    1 cord for USB keyboard
    1 cord for power to my speakers
    1 cord to connect speakers to PC

    Let's do the math. 2/11 of those cords can be fixed with UWB. Unless wireless power is part of the spec, I'm quite sceptical of its desk clearing ability...

      I could be all wrong about UWB, but I believe that they want to clear 7 of those.

      2 VGA cables to my dual monitors 1 Coax for my cable TV (would only count if you had a desktop case) 1 cord for USB mouse 1 cord for USB keyboard 1 cord to connect speakers to PC

      The RF antenna and PC power cords are not on your desk. (given that you don't have a desktop case)

      That leaves 3 power cords out of the 8 I would have counted. That is a pretty good improvement. Good enough to warrant more RF noise? That is another story...
    • Technological advances sometimes seem silly when they are first introduced. But you have to remember that new devices and applications will be developed to utilize the technology. I think people will find a lot of uses for UWB, especially in syncing portable devices like cell phones and MP3 players. Maybe you don't see a need for it, but there is also a lot of potential in wireless speakers, displays, and printers. The point of UWB isn't just to clear your desk of wires. It is also to make life more co

      Why not use a USB device that would work wirelessly and allow you to place in a better position to actually place an antenna? Which leads us to...

      1 Coax for my cable TV
      I'm assuming this is cable to the TV itself (tho I'm unsure to what percentage of the average business desktop this would be found), but this could be a USB tuner/capture device as well (better if it includes FM!),
    • While your example does bring an interesting point that we'll never do away with cables as long as we need power ( unless... [thinkgeek.com]), I don't think your example is typical, but not unreasonable either though, but I'll try and make a point anyway.

      Most people don't have dual monitors. Most don't have FM tuners or TV tuners, and UWB would be capable of providing reasonable alternatives (internet radio, streaming video). UWB would be capable of streaming audio directly to the speakers just like a bluetooth headset, bu
