Bluetooth 4.0 – Versatile and More Energy Efficient Than Ever
On April 20, the Bluetooth Special Interest Group (SIG) announced the upcoming release of its Bluetooth Version 4.0 technology. The excitement is centered on the technology’s low energy – high performance capabilities, which will allow the technology to expand into sports and fitness, security and home entertainment button-cell battery applications.
Bluetooth v4.0 combines three characteristic Bluetooth technologies: classic, low-energy, and high-speed. These integrated technologies can be used separately or in combination with each other, depending on the application. For example, glucose monitors and pedometers most benefit from low-energy technology as it saves power, cost, and space within these devices. Fitness watches will use both low-energy technology to collect data from body sensors and classic technology to send the data to a storage/display device such as a PC. Mobile phones and PCs will take advantage of all three Bluetooth technologies running side by side.
Although the Bluetooth v4.0 technology was introduced in December 2009, mobile phone and PC manufacturers can expect the fully functional package to be available to enhance their product lines by June 30. However, end users are not likely to see the improved devices until late 2010 or early 2011.
