During the annual All Hands Meeting in Seattle, the Bluetooth Special Interest Group (SIG) detailed the newest Bluetooth Core Specification, version 4.0. Apparently, the main focus of this standard is low energy consumption and as far as we know, Bluetooth 4.0 is expected to reach the market at the end of Q2 2010.
Apparently, the low energy mode will allow the technology to reach out in different areas, like m-health, sports and fitness, plus security and home entertainment. Bluetooth 4.0 should be available on products such as watches, remote controls and medical devices, plus home sensors. We have to mention that this standard is like 3 specifications in one: Classic Bluetooth, Bluetooth low energy and Bluetooth high speed.
Aside from saving power, the new technology has a wider range of coverage, up to 200 feet and even beyond. The specification for Bluetooth 4.0 with the low energy feature was first introduced in December 2009, but the first devices to use it will arrive in late 2010 or early 2011.
