Bluetooth body confirms Wi-Fi 'hijack' plan
802.11 to speed Bluetooth transmissions
Mobile World Congress The organisation behind Bluetooth will tomorrow go public on its plan to borrow bandwidth from Wi-Fi, allowing the device-to-device wireless connection technology to offer faster data transfers when it needs to.
It's a stepping stone, of course, until Bluetooth is firmly fitted on top of ultrawideband (UWB) radios, but until then, the trick – which it began hinting at privately late last year - should provide it with a speed boost way beyond what it can deliver today.
How does that square with Bluetooth's low power consumption characteristics? Bluetooth will only leverage Wi-Fi if it needs it, and if the technology is present in the host device. It already is, in plenty of laptops and, increasingly, mobile phones too.
If Bluetooth detects that an application wants to transmit a large quantity of data, it will be able to grab the 802.11 radio temporarily. Once the data's sent, Bluetooth lets go of Wi-Fi and goes back to its usual state.
To make this work, the organisation behind the wireless technology, the Bluetooth Special Interest Group (SIG) has to separate the Bluetooth profiles and protocols from the radio technology they currently operate on. Conveniently, it's already doing that, to enable Bluetooth to operate on UWB. So it's just a matter of building a Wi-Fi foundation that can slot in alongside UWB, Wibree - for ultra-low power devices - and other wireless transmission systems.
It's a cunning move for two reasons. First, it provides a stop-gap until the Bluetooth SIG can complete its work on UWB. Wi-Fi hardware is in place now, UWB kit isn't, and may not be until long after the SIG completes its UWB code. Second, it takes Bluetooth into the same territory as Wireless USB – as a way of connecting peripherals without cables. Indeed, the Bluetooth SIG specifically talks about Bluetooth+802.11 in terms of classic USB applications, like copying music files between an MP3 player and a PC, or sending photos from a camera to a PC or printer.
It's not going to happen soon, however. The architecture that will allow Bluetooth connections to sit on top of a variety of radio technologies isn't expected to be published to SIG members until mid-2009, so Wireless USB has plenty of time to establish itself.
The Bluetooth SIG began hinting that it might make use of Wi-Fi back in November 2007. Earlier that year, it published Bluetooth 2.1, which adds support for device pairing using near-field communictions - allowing products to be linked just be touching them together.

I prefer IEEE 802.11 Because...
Bluetooth, is a very important technology, but it's used for cell phones and smart devices for send/receive small documents and archives, i think bluetooth is less important of IEEE 802.11 Technology because wire-less is used in LAN's for conect notebooks and other devices in enterprises, and this technology can be used further distance than bluetooth and wire-less is more faster than Bluetooth too.
Avahi runs on the server (The phone in this case) to announce the service ala bonjour. It wouldn't really be needed as Samba can use WINS but it would make it easier for OSX users etc.
When I said software I mean on the client machine (ie the computer), however I fail to see why Nokia couldn't provide a Samba client as well so you could browse your computer's file shares.
I really don't see the point in alot of this software provided by manufacturers, why bother when you could use simple, well supported standards and then just use the support built into the OS that the user is clearly familiar with.
Try a decent solution
Never had any problem on Apple machines since the 12" Powerbook 867.
Had bluetooth mice, keyboards, headsets, headphones, printers all work like a charm.
Using iSync I have synced many mobile phones over bluetooth, used bluetooth to control itunes as a remote control.
Most phones have bluetooth for the headsets, which you have to wear if driving and using a mobile.
IMHO its a great, if underused technology that only a few companies like Sony Ericsson, Nokia and Apple have fully utilized.
