Bluetooth 4.0 to be finalized by June 2010

After the Bluetooth v1.x and v2.x present on most new mobile phones and Bluetooth v3.0 that uses high-speed radio layer defined in the 802.11 standard (used for different variants of WiFi) is now the turn of Bluetooth 4.0 to approach maturity.

The Bluetooth 4.0 is meeting the various versions of Bluetooth, the two previous ones but also the Bluetooth Low Energy , unveiled in late 2009, to ensure communication with smart sensors that will be found soon in many areas of e-health in sport through the home automation or entertainment ( see our dossier ).

The Bluetooth SIG, responsible for development of Bluetooth technology, today announced that version 4.0, which should be finalized by the end of second quarter 2010, will integrate well the Low Energy Mode: Bluetooth 4.0 opens the door to a large whole new markets for manufacturers of Bluetooth devices and products such as watches, remote controls or sensors for medical or home. Buttons products can use simple buttons for battery operation is counted in years rather than hours as currently, and they will enjoy greater reach with the new Bluetooth specification, "announces Michael Foley, president of the Bluetooth SIG.

Bluetooth 4.0: Sensors transfer broadband
The advantage of Bluetooth 4.0 is that it will be possible to combine different patterns for creating new uses: retrieving data from sensors Mode Low Energy and transmit them to other devices, like a computer via the Bluetooth standard example.

It is also possible for manufacturers to choose the scope of their device. While most Bluetooth-enabled devices will support a range of ten meters, sensors, Bluetooth 4.0 can exchange data over distances of 60 meters or more.

Samples of sensors using these new possibilities are already in the hands of manufacturers of semiconductors and the first commercial devices using Bluetooth 4.0 should be available by end 2010 or early 2011.
