Today from its annual All Hands Meeting in Seattle, 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, expected to be brought to market by the end of Q2, will feature a powerful low energy mode designed to enable expansion of the technology in m-health, sports and fitness, security and home entertainment scenarios where button-cell battery devices proliferate.
"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, Ph.D., executive director of the Bluetooth 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.
