USB To Go Wireless 212

Troy Samuel writes "The WiMedia Alliance is planning to make the technology known as 'ultrawideband,' or UWB, work among a wide variety of consumer electronics devices. Various organizations, including the Bluetooth SIG, have chosen the WiMedia Alliance's version of UWB technology as the foundation for a next-generation short-range networking technology." From the article: "UWB technology can deliver data rates at up to 480 megabits per second at around 3 meters, with speeds dropping off as the range grows to a limit of about 10 meters. Real-world speeds will probably be a little slower, but this is as fast as the wired version of USB 2.0 and much faster than current Wi-Fi networks are capable of transmitting data. 'This stuff is plumbing,' Roger Kay, an analyst with Endpoint Technologies Associates, said of the newer-generation wireless technology. 'It's important that it be there, it's going to be handy for getting rid of cables hanging around your desk.'"

(rather than as discrete purchases)

                      Now, with norwegian rounding-rules, you will pay 1.00 for 25 products, 1.50 for 50 products, and 2.00 for 25 products, in total 150.

      symmetric peer-to-peer interfaces like that provided by Firewire.

      Firewire actually has rather strong master/slave relationships; there's a tree, and a tree root, and a master node. But there's a negotiation process during hot-plugging which establishes the master/slave relationships.

      One big problem with Firewire is that it doesn't have a notion of device ownership. You can plug two computers together with FireWire, and that will work if both machines support IP or Ethernet over FireWire. But plug a peripheral into the same bus, and there's no mechanism to allocate it to a unique host computer. You'll get a control clash.

      Underneath, FireWire isn't really a "bus". It's actually a local area network, and its controllers work more like Ethernet controllers, with packets and buffer chains, than bus adapters.

      The "bus" aspect is that there are defined packet formats for loading and storing 32-bit data items in a 64 bit address space. In practice, though, what usually happens is that at the host end, some code formats such a packet, saying "set bit 22 of register 0x2490 at node 3", and when that packet gets to node 3, some little CPU in the peripheral decodes the packet, acknowledges receipt of the packet, a switch statement decodes the "register" address, and code notes that bit 22 means "turn camera on". No status for this event comes back; the host has to send a packet to "read" some other device register to find out what happened.

      Giving FireWire a "device register" model turned out, in the end, to be kind of silly. Something more like SCSI, with function codes and statuses, would have made more sense. (And, in fact, there's SCSI over FireWire.) You'd get back better status info, and devices which don't implement some functions would have a simple way to report that. This makes it easier to implement generic drivers, reducing the temptation to have to have a special driver for every manufacturer's device. And we all know where that leads.

      So if you're designing something like this, don't go with a device register model. Anything smart enough to talk it will have a CPU, so use it.

I can also see the point of a bluetooth mouse for a laptop, or a bluetooth keyboard for your PDA. It makes things faster and more portable, and gives you more freedom.

I don't have to keep track of batteries, and I don't get poor performance near the end of my battery life. It's all sitting on my desk not moving anyway, and there are only a few cords present on my desk - the rest are hidden behind the desk. I also like the tactile effort cords provide. When I plug my graphing calculator into my computer, when I stick a USB thumb drive in, when I connect my camera, when I plug in my headphones, or when I hook up a USB card reader, there's tactile feedback. I know I have just achieved something. I also don't find it terribly inconvenient to stick my flash drive into a front USB port.

    There's more than just reliability and feedback, though. When I unplug my flash drive or external hard drive, I know that the devices are powered down and safe from snooping eyes, and not experiencing wear and tear. I also know that when I sit down at the computer lab with my flash drive in my pocket, the guy next to me isn't stealing my files. I understand that the connection between the computer and device will probably be encrypted automatically, so that's fine. But what about the connection process? If I have to go through a lengthly process to associate the device before I can use it (bluetooth), then I'm not really any better off than I was with wired USB. If I don't have to go through that process, what's stopping the guy next to me from doing it? And in the same computer lab, with USB my mouse isn't going to suddenly decide to associate itself with the computer across the way. Now, we could password protect the flash drive. However, and perhaps I'm alone on this, I'd rather not have a password on my mouse. And what if I replace 'mouse' with 'keyboard?' You can't password protect a keyboard.
  • FTFA: "Certified Wireless USB setups are still going to involve a lot of cables"

    Actually, in the first iteration, it's going to involve twice as many cables as wired USB. ;)
  • Another way to waste power by pouring it into the air.

    Another reason to leave all our electronics on, all the time.

    Another reason why it's too inconvenient to do anything about gross over consumption and it's effect on our environment.

    but... if i've got one of these devices in my backpack and i walk past a whole heap of computers, lets say in an office for example... is it going to try and install it automatically?

  • This isn't plumbing, and it isn't a threat to WiFi. At 10 meters as the maximum distance, and 3 meters the desired distance, you'd have to have an AP every few feet just to get proper roaming and coverage. It would fit in better as a replacement for Bluetooth and "personal" devices, such as cell phone connectivity to laptops, wireless mice, headsets, etc. Of course I haven't RTFA, but with a summary that lists the distances indicated anyone can pretty much tell this isn't a WiFi replacement.
  • Does that mean these devices will flood the spectrum???

    I don't want to get rid of my cables if it means everything interfeers with everything else. Sounds like wireless hell. However it's the first I'm hearing of this technology so I'd be very happy to be corrected.
  • So whomever first observed that the benefit of USB was that you could power the damn things too was spot on. Take the NeXT cube, sure it was wired but it was ONLY ONE wire. So this has some of the same feel. I read this as a response to the completely messed up world that is Bluetooth (and Zigbee) because nobody can create a wireless standard that you and I can program without joining some $100,000 up front consortium and with $50,000 per annum bulk patent licensing rights. The first wireless proposal that
  • Hmmm..

    - Require no additional power
    - Difficult to intercept communication
    - Finite distance
    - Clutter

    UWB/ Wireless in General:
    - Requiers power for transmitter/ receiver resulting in reduced battery life or increased power consumption
    - Interception/ eavesdropping much easier
    - Tempest Emissions/ Interceptions?
    - Finite distance
    - Much more susceptible to interference

    I'm sure there's more but I'll stick with copper, thank you.
  • How many technologies do they think they are going to cram into the 2.4GHz range? It's ridiculus. Bluetooth, 802.11, ZigBee, Microwave ovens, cordless phones, game controllers, and now USB? Why can't the FCC open up more frequencies to the public instead of selling them of to the cellphone corporations?
  • What I'd really like to see is some sort of open intermediate language that the "drivers" could be written in. What I imagine is you switch on your device (or plug it in if it's wired), the computer sees it and "pairs up", they do a little handshake, then the device sends it's "driver" to the computer, the computer loads it and then it magically works... no more scavaging the internet for drivers. The reason I see it as an intermediate language is so that it could work with any type of machine (PC, Mac, nix

    So where's my wireless power!? Though I'm not sure if I want the level of radiation necessary to power all these devices wirelessly in my study.

    Back to the topic. UWB is old news, but I was recently reading some old news about it's use in localised RADAR [] applications. I'd like a "digital compas" that tells me, my wife and kids wh
