Bluetooth Gets Faster & Requires Less Power 158

Posted by CmdrTaco from the i-tought-bluetooth-was-already-dead dept.
An anonymous reader writes "The Bluetooth Special Interest Group (BSIG) has announced a new specification named "Enhanced Data Rate" or EDR for short. EDR aims to provide faster data transmission and reduce the power consumption from traditional Bluetooth technology. The data speeds will be roughly three times faster which means you could easily use multiple Bluetooth devices simultaneously. The reduced power consumption also means longer battery life and less heat generated. The new EDR standard will be backward compatible with the current standard Bluetooth devices. This makes upgrading to the new standard effortless."

      There's lots of cool things to do with Bluetooth but nobody'll implement it because they're all dumb.

      1) Cell phone "submissiveness" - an establishment (like a movie theater or a school) installs a device that causes your BT-enabled phone to shutthehellup. When this happens, the phone beeps once to notify the user of the situation. The user can opt out if he/she wishes.

      2) Tire pressures - to go along with our RFID license plates, our tires could tell our cell phones (or the dashboard) if they are low on pressure.

      3) Coupons - a person's cell phone (once again) could be configured to receive (or not) coupons at the grocery store upon entering.

      4) Wireless peripherals - the biggest usability problem with PCs these days is the rats nest behind (or on top of, in front of) the damn things. Holy shit... Some of you know what I'm talking about. This is crazy.

      Sure - it was all a nice thought and some of it even made it (I have a wireless keyboard that could have used the BT standard but didn't for WHO KNOWS what reason) but now we've got wireless-serial-attached-SCSI and every other damn wireless specification coming. Great!

      What the industry needs is an independent board to regulate this stuff. Intel doesn't like Firewire so they codevelop USB. Great! If we had a board that could pick a standard, we wouldn't be stuck with this cruft. Don't get me wrong - I'm all about having freedom but it would be nice if the industry said, "we like this standard - go ahead and develop that other crap but we will only endorse this".

        First of all, we have such a body - it's called the IEEE. And I'm sure a number of other bodies I've never heard of as well.

        As for Intel developing USB because it didn't like FW... I don't think that's accurate.

  • To really get BlueTooth accepted with the masses, it needs a Killer App. I don't think cell phone address book exchange is it.

    The killer app for BlueTooth will be a BlueTooth enabled key fob that you hang on your keychain. Lost your keys again? Just dial a magic key sequence on your cell phone, which then sends out a BlueTooth transmission. This wakes the key fob, which begins beeping loudly. Now you just walk to the sound and pick up your keys.

    The real thing which makes this a killer app is that any Bl

    • Why not take this a step further? Get rid of the keys entirely, and just have a Bluetooth device open your car/house door directly.

      That would be one hell of a killer app.
    • Your idea would work even better than you think. Because Bluetooth devices manually get paired before they do anything with each other, your phone/keychain would only cause your own keychain/phone to beep. I for one love this idea. You better get on it [uspto.gov].

The one on my pickup truck has a much better range than Bluetooth.

    The issue with regards to me adopting bluetooth has been more about the absurd pricing of said peripherals. The Linksys Bluetooth desktop (and not the fancy-shmancy Nuvo or whatever the hell it's called) runs like a hundred bucks, whereas the plain old wireless one runs for closer to $50. That's not an insubstantial difference.

    After a brief glance at Amazon, it also looks like you can't get BT phones unless they're for AT&T or T-Mobile. Considering that GSM coverage here in the USA seems to be kinda spotty compared to, say, TDMA, that's a serious drawback.

    The problem with BT right now is that it's an integration technology, yet it's difficult to use an integration technology that doesn't have wide-spread usage.

    Bluetooth group preps 2.1Mbps spec By Tony Smith Published Thursday 10th June 2004 10:38 GMT Bluetooth communications are set to get rather faster with a new version of the specification that takes its data throughput 2.1Mbps in the offing. The new version, Bluetooth Enhanced Data Rate (EDR), is offered as a "prototype specification" by the Bluetooth Special Interest Group (SIG). The technology increases data transmission by compressing more data into each packet rather than by increasing the rate at which

    There's so much "crap" out there about "bluetooth is dead, long live 802.11", or "everything will be 802.11" or "elvis works at my local 711".

    They are complimentary, remember that Bluetooth was designed _specifically_ as (a) single chip solution, (b) low power, low cost, low size, (c) a short range point to point data replacement.

    Until I see true single-chip 802.11 devices that meet these criteria, there's still a space for Bluetooth.

    After all, you don't buy "dishwasher power" for your "washing machine".

    So when am I going to be able to get a Bluetooth-enabled hearing aid so I can interface with my PC, my cell phone and other devices? Hearing aids seem like one of the killer apps for Bluetooth yet they don't seem to exist yet.
    • Two reasons, off the top of my head, why they don't exist: 1) Current technology is quite capable at addressing correctable hearing problems (sound amplification isn't complicated or new), 2) Bluetooth doesn't have the capability (until the newer, higher bandwidth devices come out) to transmit uncompressed high-quality sound (why subject people to hearing the world at telephone quality if you don't have to).

        IANAA (I am not an audiologist), but... I've been wearing a set of digital hearing aids for about five years. They do in fact interface with a PC though a small adapter that fits in the battery door. This allows my audiologist to adjust the frequency equalization curves & even draw down my last audiogram, which is stored in each hearing aid. Moreover, the hearing aids have my name & patient number recorded in them. I
