Plans are underway to link together two popular technologies—Bluetooth and Wi-Fi—so that users can quickly move huge files, such as music libaries or pictures, from a device to a computer, said the Bluetooth Special Interest Group (SIG) today at Mobile World Congress.

The details sound pretty technical, but what you need to know is that the Bluetooth SIG is essentially creating a new specification that would allow Bluetooth to maintain attributes, such as security and pairing, but jump over to a Wi-Fi radio in a device in order to achieve higher speeds and greater capacity. When a file transfer is complete, it would go back to the standard Bluetooth radio to save battery life. Release.

It is expected to be ready for its members by mid-2009, beating another utra-wideband technology to market called WiMedia Alliance (Not to be confused with Wibree). As the development work drags on, the SIG said it is going to use 802.11 in the meantime because it exists in so many devices today. “We’re committed to speedy wireless personal area network connections and we’ll always be looking for the best near term and long term way to accomplish that,” said SIG director Mike Foley.
