Nokia and Wibree
Nokia has launched a new digital radio technology called Wibree. The intention is for Wibree to work in conjunction with Bluetooth. Wibree's big plus is that it has very low power consumption.
This addition to the wireless mix will improve battery life on future devices, which is great news - considering that this has been one of the main N91 gripes.
