Bluetooth 3.0 is Fast Like Ricky Bobby

Shake and bake!
The Bluetooth SIG during its annual meeting finalized the Bluetooth 3.0 + HS (High Speed) specification.
The new High Speed classification comes from the inclusion of the 802.11 standard for file transfers over Bluetooth.
"Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Foley, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."
Bluetooth 3.0 + HS is backwards compatible and builds upon all the features we have right now from our existing Bluetooth 2.1 + EDR devices.
However, the really cool feature in the new version, is how Bluetooth 3.0 will handle the transfer of large files. Most of us use Bluetooth right now for low-bandwidth applications such as headsets or computer mice, but when it comes to transferring media, we’d prefer plugging our devices in via USB. Bluetooth 3.0 aims to fix the throughput issue by levering 802.11 that we’ve all come to love from our Wi-Fi devices.
During transfer of a file, Bluetooth 3.0 will turn on the 802.11 radio to enable data transfers at the approximate rate of 24 Mbps. After the transfer is complete the radio is powered down to save on energy.
According to Engadget’s talk with Foley, existing Bluetooth hardware in laptop computers might be upgradable to 3.0 + HS provided that there is also 802.11 present. Upgrading music players or cell phones is something “you can pretty much forget about happening,” although we’re curious about the high-end cell phones of today that have both radios built-in. For the most part, expect having to buy new devices to get the full benefits of the new Bluetooth.

Bluetooth: A Rundown
Everyone has heard of Bluetooth by now. After all, this technology has been in the making for more than seven years. Now that Microsoft has released the first Bluetooth keyboard and mouse set, this seems like a good time to have a proper look at the technology. While we're at it, we'll also take a good look at that first keyboard and mouse set, the Microsoft Wireless Optical Desktop for Bluetooth.

I too wonder if advanced cell phones with bluetooth as well as 802.11 antennas will be able to 'upgrade' to the new standard. I currently have an ATT tilt, and I HATE synching it to the computer to get media onto the device. Likewise, taking the micro sd card out of the phone and into the computer to put media on it makes me nervous, as it's always a struggle and I'm afraid to break the chip in half. I love using bluetooth for media transfer, but it is SOOOO slow when the file is 10MB+!
I think it is not good.
if you have wifi, why you need bluetooth to utilize it? I think, bluetooth is like a software to use it.
So it is not a real improvement.

They should call it "Magic Man" or "El Diablo" instead of Bluetooth 3.0
I somewhat agree with akhodjaev. It seems to me that all they are really doing is outsourcing transfers to 802.11 and calling it Bluetooth 3.0, when it's still just two different technologies working together. You could accomplish the same thing with software using the existing standards. In fact, if all you wanted to do is sync a device or transfer data, you wouldn't need Bluetooth at all if you already had 802.11.

Totally agree here. This isnt bluetooth 3.0, this is bluetooth 2.0+Wifi through software emulation.

Can i add this to what i want on the new iphone? or is that to late...
Gotta love how more than 50% of the comments here are about Talladega Nights lol

You're confusing the various layers of the stack. The wifi radio is simply the physical layer. Bluetooth adds the convenience of ad-hoc point to point connectivity without requiring a full TCP/IP implementation on either side. I mean do you really care what type of radio implements your current BT? We should applaud the BT SIG for trying to re-use installed and cheap commodity hardware to enhance their product. If they'd done that earlier on BT would be much more widely adopted right now.
If it makes sense for devices to support TCP/IP then the 802.11 radio can do both BT and wifi. For file transfers BT seems more suitable as it's essentially a wireless serial link. Wifi is not.

isn't "El Diablo" spanish for "fighting chicken"?
rick rolled? lawls!
This is stupid, why not just impliment the BT layer 1 stack on the 802.11(what version) radio and do away with the BT radio?
This is a simple software solution that has no additional BT features, it just offloads the task to the better component.
BT should only be for headsets, pairing phones, etc. It's like email, it was never intended as a file transfer tool, users just misuse it out of stupidity or just plain being naive to the tech.

must be 802.11g since it's limited to such a low speed - but still over twice that of 802.11b - and only b/g/n are common after all... and they speak of a common radio.
I think this is a great solution:
1. Bluetooth was designed to use as little power as possible. My phones battery drains rapidly when I enable the 802.11 antenna while when only using bluetooth the power lasts longer.
2. The technology enables the use of an already existing hardware to facilitate more efficient transfers of data. Transferring over bluetooth for 15 minutes (when I transfer movie clips and such that IS how long it takes because USB synching sucks on my headset) will drain more power than transferring over wifi for a minute or less.
I think crowning it bluetooth 3 IS misleading though. Like someone else said, it should be called bluetooth 2+wifi
As a side note, I REALLY wish MS would re-enable their synching over bluetooth option. Their ActiveSynch used to have that option, but they disabled it due to security concerns... personally, I always have my bluetooth off if I'm not using it, so they took the feature away for people who are too lazy to set security on their devices.
to andethnfdhh: I always sync my i760 and Omnia via bluetooth, to both my xp work laptop and vista desktop.
