The Bluetooth 4.0 low-power wireless networking specification has been approved, and the technology will start appearing in devices such as smart meters and laptops later this year. Chips with the Bluetooth 4.0 standard have gone through a rigorous testing process, and the technology is being certified and licensed for use in chips and devices, the Bluetooth Special Interest Group (SIG) said on Wednesday.

The upcoming Bluetooth version will be optimized for low power battery operation which will help the technology to conquer new markets such as health care, fitness and sports where devices require low power and low cost wireless connectivity.
Lower power consumption will also allow the technology to be used in way smaller products than before such as tiny coin-cell battery powered devices and sensors. According to the Bluetooth SIG, thanks to the decreased demand for power, products will be able to run for years on standard coin-cell batteries.
The other improvements brought to Bluetooth by v4.0 include low cost, multi-vendor interoperability and enhanced range.
