Bluetooth Gets a Speed Boost

Tom Keating writes to tell us that the Bluetooth SIG has announced the adoption of WiMedia's version of ultra-wideband technology for integration into current Bluetooth technology. This move hopes to push the popularity of Bluetooth by providing a new high speed option that can transmit high quality sound and video. WiMedia also has a copy of the announcement [PDF] on their site with a few additional details.

  1. Roaming p2p mesh networks? by Anonymous Coward · · Score: 3, Interesting

    With its current market penetration this will make Bluetooth the ideal choice for a Linux HTPC remote control with VOIP capability.

    But will it be good enough for instant roaming networks? I would love alert fellow road users that my bike is coming out of the ally and know that someone want in at almost the same time so that we can slow down or speed up without having to brake hard when we meet face to face at the corner.

    Not realy a big aftersales market like car navigation so Linux using a mass sold protocol would be ideal. Will blutooth become good enough for such applications?

    is there really a need for it when we now have WiFi which has a better range ?

    You're missing the point of Bluetooth, it's all about cheap low powered comms. Range is not an issue for most apps that utilize BT, for things like transferring data, performance was really the main sticking point. If they can come out with a wifi spec that used significantly less power and was cost effective for the type of devices that they wish to integrate into, then perhaps something like wifi will supplant BT.

  3. As one of the original inventors of Bluetooth... by schoolsucks · · Score: 1, Interesting

    This makes me really glad. Now that I am out of the project and focusing more on open source projects, I don't get to read about Bluetooth much. This just made my day.

    the point of bluetooth is to be LOW POWER so it can be REALLY SMALL and you can't have video capable bandwidth in a micropowered device.

    If you RTFA, you'd have noticed that they are trying to keep the same power requirements by making efficiencies in the design. But you do make a valid point - how much power could they save without this high bandwidth?

  5. Oh yeah, great... by grahamlee · · Score: 3, Interesting

    ...so now we've got ultra-wide bandwidth combined with rapid frequency shifts. That's going to suck up big chunks of the unlicensed broadcast band at a time - I hope no-one's using a microwave (or a wireless router, especially a pre-N one) when I'm transferring my pr0n from my phone to my portable video player...

    No kidding, what the hell is the use of this? If you're looking for speed, use WiFi. Bluetooth is for wireless keyboards and shit.

    Mobile phones. I use BT on a regular basis to transfer files to and from my mobile. My mobile plays unprotected AAC files from my iTunes Music Library, so it's not uncommon for me to upload a few mega file to my phone - and backwards goes a few mega video file shot by the built in camera. And yes, I would appreciate if the progress bar could move slightly faster.

    The licensing costs of Bluetooth are the reason for its slow adoption.

    There is no reason for a Bluetooth wireless headphones to cost $200 or more, other good quality wireless headphones with proprietary wireless technology could be purchased for $80.

    Bluetooth mice and keyboards are like 50% - 100% more expensive then those wireless mice and keyboards with proprietary wireless technology. In fact, I heard it was cheaper for a company to developer their own wireless technology rather then licence Bluetooth for their products.

    With wireless USB entering the market this year, I would be reluctant to buy anything Bluetooth until we see how Wireless USB will handle and how inexpensive it will be to license and use the product. My guess is that most companies using a proprietary wireless connection will adopt Wireless USB quickly.

    For now, the only niche market that Bluetooth is succeeding in is in cell phone headsets. When it comes to general computing, Bluetooth's days are numbered.

  8. Bluetooth by DarthChris · · Score: 2, Interesting

    As I understand it, bluetooth (like most wireless) isn't very secure. If that's the case, wouldn't it be prudent to fix this before giving it a speed boost?

    it's going to use more electricity, the power requirements will have to go up.
    Wrong. Thanks to Shannon's Law, UWB can drastically cut its power output in exchange for using a huge slice of spectrum, and still be much faster than Bluetooth. Since UWB goes under the FCC limit of -41 dBm/MHz, even if Bluetooth uses Wi-Media's entire 7 GHz spectrum, you're only looking at about 0.5 mW to transmit. In comparison, Bluetooth ranges from 1 mW to 100 mW, depending on the power class. And that's even before you consider that UWB potentially has simpler circuitry, making it cheaper to actually drive the radio; or that the much higher data rates you get from UWB means you won't have to keep the radio on for nearly as long.

    Isn't technology great?

  10. Does it even really matter? by Jtheletter · · Score: 2, Interesting

    Does anyone seriously think that this would even be put into cellphones and not horribly crippled by the major providers? Time and again we've seen artifical restrictions put on cellphones in an attempt to charge exorbitant fees for things as simple as moving cameraphone pictures to your computer. We're no longer being nickle-and-dimed to death, now it's a dollar or five at a time. Want to transfer video to your phone for viewing on the train using this new bluetooth high speed feature? No problem, you just need to sign up for our BlueVideo plan at a scant $9.99 per month, and expect download speeds to be about the same as regular bluetooth since we've totally crippled the standard to prevent all you hax0rs from trying to put data you own on the phone you own in the manner of your choosing. And don't forget our soul-sucking DRM for that video format! Why have 15fps when you can get 6fps in twice the memory space?
