The Bluetooth 3 spec was adopted in April of last year. Basically all Bluetooth 3 did was allow device pairing and discovery to use the Bluetooth radio and any large amount of data to be sent through 802.11. This gave the connection the ability to transfer data quickly while maintaining low power usage for establishing connections.

Now, a little over a year later, the Bluetooth 4.0 Spec has been adopted by Bluetooth SIG (Special Interest Group). The 4.0 spec includes three protocols: Classic Bluetooth, Bluetooth high speed and Bluetooth low energy. The emphasis on the spec is low power usage. According to the SIG, Bluetooth 4.0's spec will enable devices to be powered by coin-cell batteries for years. A change in modulation has also increased the range from around 30 feet to over 200 feet.
