Bluetooth 4.0 Uses Less Power While Extending Range

Bluetooth 4.0 just got finalised and will start rolling out to devices by the end of the year. Along with extending range from 10 metres to 61 metres, 4.0 introduces a new low-power mode that will be seen in either single or dual-mode iterations.

The single-mode chips are strictly low power which means it can be tossed into watches, remote controls, and a variety of health, fitness and in-home sensors. Dual-mode chips combine that same low energy mode with the ability to transfer data over 802.11 Wi-Fi, much like what we've seen with Bluetooth 3.0. Think of it like two Bluetooths. Or Blueteeth.
