Bluetooth 4.0 with low energy technology paves the way for Bluetooth Smart devices.

Bluetooth v4.0 introduced low energy technology to the Bluetooth Core Specification, enabling new Bluetooth Smart devices that can operate for months or even years on tiny, coin-cell batteries. Markets for these new devices include health care, sports and fitness, security, and home entertainment.

Bluetooth v4.0 is the most recent version of Bluetooth wireless technology. It includes a low energy feature that is the basis for Bluetooth Smart devices. A product bearing the Bluetooth Smart and Bluetooth Smart Ready logos must include Bluetooth v4.0, but must also meet additional criteria.

The Bluetooth SIG announced the formal adoption of Bluetooth Core Specification Version 4.0 in July 2010. By mid-2011, many devices based on this technology were under development and headed to market soon, including the first wave of Bluetooth Smart Ready mobile phones due out in late 2011.

This technology is creating new opportunities for developers and manufacturers of Bluetooth devices and applications, bringing to life entirely new markets for devices that are low-cost and operate with low power wireless connectivity.

Bluetooth low energy technology features

Key features of Bluetooth low energy wireless technology include:

Ultra-low peak, average and idle mode power consumption
Ability to run for years on standard, coin-cell batteries
Low cost
Multi-vendor interoperability
Enhanced range

Bluetooth version 3.0 was launched last year, but it did not become popular enough due to the power requirements needed. Hence Bluetooth version 4.0 has been created to overcome this problem.
Today, a group of individuals have announced that a new version of the Bluetooth technology is arrive. They have also announced that the new version i.e, Bluetooth 4.0, will be coming in the last quarter of this year. Latest devices such as headsets, mobile phones and computers and other kinds of technology will be having this latest technology.

Bluetooth 3.0 devices used to require at least a triple A-batteries or larger capacity battery to function. But in this latest technology i.e, Bluetooth 4.0, it will allow devices with smaller batteries to work efficiently.

Bluetooth 4.0 will be consuming lesser power when compared to their preceding versions, and will have a higher data transfer rate. It will carries the high-speed Wi-Fi feature which was introduced with Bluetooth 3.0. That allows the devices to jump onto Wi-Fi 802.11 networks, where data transfer rate is up to 25MPS
