As we reported last October, the Bluetooth SIG is working on a faster version that will run over Wi-Fi.

The news emerged at the Bluetooth Evolution conference in London last October, but has only just been officially announced by the Bluetooth Special Interest Group (SIG), at last week's Mobile World Congress in Barcelona.

The SIG made the move because its previously preferred technology for fast Bluetooth, ultrawideband, was too slow in getting to the market in products. Indeed, UWB, despite its obvious usefulness in handsets, was notable for its complete absence at MWC (if you were there with real ultra-wideband products, please get in touch).

The Wi-Fi version of Bluetooth should be on stream reasonably quickly, meaning that dual mode handsets you buy next year may be able to switch from regular Bluetooth to Wi-Fi for faster data transfers.
