As with any updated specification for a standard, Bluetooth 4.0 is no different as it sports a couple of notable improvements including the ability to be used in low-power devices such as watches and pedometers that are powered by coin-cell batteries. This is a definite step forward since its predecessors could only handle triple-A or larger-capacity batteries at best. Apart from that, Bluetooth 4.0 will adopt low-energy specification (Ble) for “the transmission of small bursts of data in addition to the high-speed data transfer capabilities introduced with Bluetooth 3.0 last April.” While most of the world is still rocking to Bluetooth 2.1, expect to see devices sporting the new Bluetooth 4.0 specification to hit the market by the end of this year.
