The Bluetooth Special Interest Group is set to announce the Bluetooth 3.0 specification later this month. Bluetooth 3.0 will feature dramatically increased speeds, allowing for the transfer of large video files, music collections and photo libraries wirelessly 'within seconds'. The spec also includes a new ability called Enhanced Power Control. EPC will reduce the occurrence of disconnects that can be caused by actions such as putting a phone in a pocket, backpack, briefcase or purse. Bluetooth 3.0 uses Generic Alternate MAC/PHY (AMP). This is what lets Bluetooth profiles operate at Wi-Fi speeds. The 802.11 Protocol Adaption Layer (PAL) will enable the Generic AMP feature to be used with an 802.11 radio. Bluetooth is used to create the pairing between two devices, but the data transfer itself is handed off to Wi-Fi. In order to take advantage of the higher transfer speeds, both devices need Bluetooth and Wi-Fi. If Wi-Fi isn't present on one of the devices, the spec reverts to Bluetooth for data transfer. More details will be available, including a list of chip makers that are lined up to support the new spec, on April 21.

From the sound of it...

it would seem feasible for an existing device that has both bluetooth and Wifi could take advantage of Bluetooth 3.0 though a firmware update. Since basically it only uses bluetooth to pair the device and then passes it off to Wifi for data transfer.

Maybe I'm missing something tho... Confused
this is what I meant to say thanks for making it clear. I have been unable to find any information so we will just have to wait

backwards compatible?

will the PAL or AMP profile be backwards compatible with current phones that have wifi and bluetooth radios such as the nseries?

About time

Transfer speed, I feel, it the only limitation of wide use of Bluetooth...

Multiple device connection would be nice too.

But connection speed is the biggest.
