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.
Now we can all throw out our old Bluetooth devices, so we can upgrade. I can't wait to take a video of my friend on my phone, then show it to him on my phone, then send it to his phone, then watch it on his phone too! I hope they come out with a newer, faster one right after I get this one.

It is critical that the UWB technology be compatible with Bluetooth radios and maintain the core attributes of Bluetooth wireless technology - low power, low cost, ad-hoc networking, built-in security features, and ability to integrate into mobile devices. Backwards compatibility with the over 500 million Bluetooth devices currently on the market is also an important consideration. The Bluetooth SIG is satisfied that MB-OFDM UWB technology, offered by the WiMedia Alliance, is capable of meeting all of these requirements.
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.
UWB has signal range like wireless - in the tens to hundreds of feet. Easily across the house. Freescale have demonstrated the OTHER UWB standard (UWB Forum) streaming MPEG2 video from one device (a home theater box) to a UWB TV. It was really quite neat.

Hopefully adopting the WiMedia version and using Bluetooth as the remote control method of choice (why not control your TV and media center from your mobile phone, even?
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?
...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...
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.
I haven't thought of anything clever to put here, but then again most of you haven't either.
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?
Don't you just hate it when people reply to your signature?
I prefer using wired connections... it gives me the security of knowing that if I fall off a cliff while talking on the phone I will at least have a tether.
This just in! 3 out of 4 people make up 75% of the population.
Another thing to keep in mind is that higher speed doesn't always mean more battery consumption. Compared to Bluetooth 1.2, Bluetooth 2.0's higher data rate means a shorter time where you have to have the transmitter powered on and therefore an overall power savings.
That's just being ignorant.
In 1951 Remington Rand was selling UNIVAC1 computers to the government. The thing could do about 1,900 operations per second and had I think about 72kilobits of ram.
It drew 125 Kwatts of electricity.
The laptop sitting in front of me now is about 300,000 times faster and draws 25 watts during peak usage.
What on earth makes you think that just becuase something is faster/better, it therefore must (by some magical law of physics I'm sure) draw more power?
With advances in chip fabrication alone, it is possible to massively reduce power usage. Not to mention any progress they make in the actual protocol being used by the system that may reduce transmission.
Also, you seem to be mistaken on the work the chip actually does. It is not processing any audio or video streams, it could care less if it was transmitting HD video or text, it'd just passing on the packets.
Big ones, small ones, some as big as yer 'ead!
Give 'em a twist, a flick o' the wrist...
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?
