The Bluetooth Special Interest Group (SIG) unveiled more information about its forthcoming Bluetooth Core Specification Version 4.0, with the hallmark feature of low energy technology. Bluetooth v4.0 is expected to be brought to market by the end of Q2.
According to SIG, Bluetooth v4.0 is like three specifications in one – Classic Bluetooth technology, Bluetooth low energy technology, and Bluetooth high speed technology– all which can be combined or used separately in different devices according to their functionality.
For example, sensors like those in pedometers and glucose monitors will run only low energy technology, thus saving power, cost and space within the device. Watches will take advantage of both low energy technology while collecting data from fitness sensors on the body as well as Classic Bluetooth technology when sending that information to a PC, or separately displaying caller ID information when wirelessly connected to a mobile phone.
Mobile phones and PCs, which support the widest range of uses, will utilize the full package with Classic, low energy and high speed technology running side by side.
As with previous versions of the specification, the range of the Bluetooth v4.0 radio may be optimized according to application. The majority of Bluetooth devices on the market today include the basic 30 foot, or 10 meter, range of the Classic Bluetooth radio, but there is no limit imposed by the Specification.
SIG says that with Bluetooth v4.0, manufacturers may choose to optimize range to 200 feet and beyond, particularly for in-home sensor applications where longer range is a necessity.
“Bluetooth v4.0 throws open the doors to a host of new markets for Bluetooth manufacturers and products such as watches, remote controls, and a variety of medical and in-home sensors. Many of these products run on button-cell batteries that must last for years versus hours and will also benefit from the longer range enabled by this new version of the Bluetooth specification,“ said Michael Foley, executive director of the Bluetooth SIG.
Bluetooth v4.0 was recently named one of the “10 Mobile Technologies to Watch in 2010 and 2011” by Gartner, Inc. Technologies chosen for the list were selected on their potential to evolve and impact short-term mobile strategies and policies.
Specifically, Bluetooth v4.0 is cited to have significant impact on the fitness, healthcare and environmental control industries.
