Bluetooth to Piggyback on Wi-Fi

The popular wireless technology known as Bluetooth could get a lot faster next year by taking advantage of Wi-Fi technology already built into many gadgets.

Linking Bluetooth and Wi-Fi may make it easier and faster to transfer large amounts of music between computers and cell phones, or send pictures from a camera phone to a printer, or video from a camcorder to a TV.

The combination devices will use the regular low-power Bluetooth radios to recognize each other and establish connections. If they need to transfer a large file, they will be able to turn on their Wi-Fi radios, then turn them off to save power after finishing the transfer

Devices won't be available until the middle of next year, but with ultra-wideband falling ever behind schedule, this looks like a great interim plan to boost transfer rates and hold down power consumption.
