With Intel leading the way to push forward wireless USB (WUSB) technology, some say this could lead to the demise of Bluetooth. Read on and see what you think.
If Intel has its way, Bluetooth will be a dead technology by the end of 2005. Intel’s pushing hard for a new wireless USB standard, called WUSB. The goal is to design a wireless standard that’s faster and more reliable than Bluetooth. The faster part is the key. WUSB is being set up as a counterpart to 802.11, handling the device to device transfers WiFi doesn’t cover; like the movement of audio and video files between PCs and cameras, MP3 players and the like.
While I’ve been quite the vocal fan of Bluetooth, the promise of WUSB has me close to salivation. If the goal is realized, WUSB will have data transfer rates of 480 megabits per second at a range of 2 meters. That’s quite an improvement over the 12 megabits per second that Bluetooth delivers.
As part of any wireless conversation, it’s important to understand where these technologies play. What Bluetooth and WUSB are competing for is dominance in the short range communications arena; previously lead by infrared communication. While WUSB is the soon-to-be new kid on the block, Bluetooth has been around for years, though its purpose has been viewed as unclear by most.

Dont think, that bt will disappear, more it will be developed and maybe renamed.

I am reminded of this image from pocketpcthoughts when they ran a similar story
however I think now that bluetooth is establishing itself in many many products it will no so easily be discarded

Bt is the basic of the waveland technology as i know, what makes possible internet use in airplanes.
Posted by masseur
unfortunately thats incorrect. the internet setup by Connexion on Lufthansa and now British airways aircraft is using WiFi. See this Boeing press release for example

@masseur my mistake, thx. Read about it a year ago in a short article.

The so called dead ones are always living an amazingly long life.

surely distance will be just as important a speed. With the increase of bluetooth with 100m range, this will be a big factor of a 2m range of WUSB. Unless it does offer more than 2m range, but a slower speed.

You can't bluejack too many people from only a 2m range!!

lol run up to the person u wanna blue jack then run away and see the results haha
Posted by wally
LOL, you would have to WUSBjack them
Posted by masseur
is it me or am I right in thinking that every bluetooth conversation lately seems to end up in bluejacking discussions? sureley there is more to bluetooth than that (although thats probably the most fun use!)
Posted by Sammy_boy
Not quite got the same ring to it really, does it?
Besides, 2m is within whacking range if the person you've just blue/WUSBjacked didn't find it quite as funny as you did and reacts with physical violence!!

I wonder how much power wusb uses, that's one of the main factor that manufacturers will take into account when designing devices and deciding what wireless standards game hardware to use.

WUSB performance at launch will provide adequate bandwidth to meet the requirements of a typical user experience with wired connections. The 480 Mbps initial target bandwidth of WUSB is comparable to the current wired USB 2.0 standard. With 480 Mbps being the initial target, WUSB specifications will allow for generation steps of data throughput as the ultra wideband radio evolves and with future process technologies, exceeding limits of 1 Gbps.
The specification is intended for WUSB to operate as a wire replacement with targeted usage models for cluster connectivity to the host and device-to-device connectivity at less than 10 meters. The interface will support quality delivery of rich digital multimedia formats, including audio and video, and will be capable of high rate streaming (isochronous transfers).
Radio System Power and Power Management
Radio system power (power used only by the radio) will be expected to meet the most stringent requirements where mobile and handheld battery life is important. For example, typical PDAs use 250–400 mW without a radio connection, while typical cellular phones use 200 mW–300 mW with the primary WAN radio. Adding a WUSB radio should not increase power requirements any more than existing wireless technologies already employed today.
Battery-powered operation requires reasonable battery life: 2–5 days for highly mobile devices and several months for intermittently used devices like remote controls. WUSB, based on the MultiBand OFDM Alliance (MBOA) radio, will strive to meet these standards. The power target for WUSB radio will be introduced at less than 300 mW and drive to a target of 100 mW over time.

@ axxxr & all:
As a, dare I say it, prolific Bluetooth user (see sig.) I'm not phased.
A key factor is probably size - seen any Wifi devices the size of some BT headsets?
WUSB will probably end up having a very tiny niche, if at all.
I'm very happy being able to quickly n easily send sound files & pics from my phone to PC (& vice versa).
Printing via my HP 'BT-enabled' portable printer is just a joy each time I do it. (Haven't seen a wifi version of this yet either)
BT Cameras will start to appear in greater numbers.
It's a great device-specific concept with it's strength being ( & sometimes, I'll admit frustration as a user) the manufacturer's ability to utilise the technology for a specific useful task.
There are and will be more applications coming out all the time (even the humble old TV remote could get a look in with distributed home TV networks being difficult to manage with IR - line-of-sight limits.)
Finally, Marketing.
When you first hear it (Bluetooth) you're just plain puzzled, right?
But, let's face it, it grows on you - and it's quite catchy & definitely memorable.

Everyone's talking about the coming death of Bluetooth.I don't think so!
Wireless USB, which should start showing up in real products in about a year, will "kill" Bluetooth, according to researchers and engineers at Intel and elsewhere.
Wireless USB, which will involve a universal short-range wireless USB dongle you plug into a PC, will be faster, more reliable and easier to install and use than Bluetooth, according to the experts. The spec on it is being completed as I type this.
The exact same predictions happened about five years ago, when engineering types proclaimed the death of Bluetooth in favor of Wi-Fi, citing many of the same problems with Bluetooth.
They're wrong again, and for the same reason: Naysayers assume Bluetooth is a cable-replacement technology for PCs. Yes, Wireless USB sounds great, and may well replace PC cables, wirelessly connecting keyboards, mice, web cams and cradles. But that's not what most people use Bluetooth for.
Bluetooth is the best thing we have -- and the best thing we're going to have in the foreseeable future -- to connect other things at short range.
Bluetooth is most useful for connecting things to your cell phone -- headsets, printers, keyboards, etc., -- and in the near future, digital cameras, vending machines and other cell phones.
And we're witnessing an explosion in the use, applications and cost-reduction of small, mobile devices. Most of these new gadgets will not have USB ports. Bluetooth will connect them.
Bluetooth is one of those technologies designed to be a stop-gap, but ends up because of popular demand (for applications and peripherals that support it) being more important than the technologies designed to replace it. You know, like Windows, which was a stop-gap operating system between DOS and OS/2.
If wireless USB is extremely successful -- and I hope it will be -- it will become the cable-replacement technology engineers have long dreamed of: fast enough for graphics, easy enough for consumers. But Bluetooth will be with us for years and years as the preferred technology for wirelessly connecting our gadgets at short range.
