Bluetooth 3.0+HS arrives without the HS
High Speed in name only
Magic Quadrant for Enterprise Backup/Recovery
The next version of Bluetooth is being launched today, though anyone hoping to see ultrawideband (UWB) capabilities will be disappointed to see that for the moment "HS" means Wi-Fi speeds over a Wi-Fi carrier.
Bluetooth version 3.0+HS will have some other new features, but it's High Speed that's going to attract the attention as Bluetooth has been struggling to accommodate the increasing quantity of data that users want to synchronise between mobile and fixed devices, including hefty music and movie files.
Wi-Fi is only one of the alternative carriers that Bluetooth should eventually support, with WiMedia's implementation of Ultra Wide Band promising 480Mb/s... eventually. For the moment, Bluetooth 3.0+HS users will have to content themselves with 802.11 speeds.
These alternatives don't involve dropping the existing Bluetooth protocols - the idea is that two devices connected using existing the Bluetooth standard might decide a faster connection is needed and negotiate to discover they both support "+HS" or greater. In such a case, a separate connection is established, peer to peer, using (in the first instance) wi-fi as a carrier for the Bluetooth protocols.
The original Bluetooth connection remains in place and manages the faster connection for the duration of the transfer, then shuts it down. This maintains backwards compatibility, while offering faster connections where both devices support them.
Version 3.0 will also support better power control and the ability to suspend connections for longer - both of which should increase the stability of connections while on standby. ®

and onto wi-fi powered headsets
how long will it be before we have wi-fi powered headsets?
And some idiots out there will think that is a good thing!
Isn't the power of marketing good! NOT!
Gotta agree with Bucktooth
It may not have become the defacto high speed data protocol is was touted to be, but in terms of core connectivity functionality, it has certainly become very common place. Even vehicle GPU's and fault diagnostic modules are bluetoothed into these days. When a technology jumps outside of the original application 'boundaries' into areas like this, you'd be hard pressed to say it wasn't a success.
How many laptops were previously wrecked by the user not unplugging the USB cable to their phone before throwing the computer into a bag and the USB socket bending and breaking the motherboard?! Gimme bluetooth over a cable connection anyday for the day to day linking and syncing up.
Bucktooth - Its been a success.
Misspelling for comedy effect.... Anyway I would say bluetooth has been a successful and useful technology it connects my phone to my car automaticly to my laptop to sync , adhoc transfers with my friends. I really wish it was used more for example... Memory card readers, cameras, syncing tomtom, I think mouses and keyboards use it, external drives... yes maybe its a bit slow for that but it all seams frustratingly slow. I have a new work laptop (so not my choice) NO Bluetooth? why does such an option even exist its got a/b/g wifi? So we really still have plenty of uses for bluetooth as I sodding hate carrying cables for everything else still! Oh yeah more bluetooth printers please!
