By on December 18th, 2009

Bluetooth is one feature which everyone in today’s modern world uses to share files withbluetooth his or her friend circle. Currently Bluetooth is in version 2.0 and Bluetooth 3.0 will soon be implemented in mobiles from next year. Today at Bellevue, WA, the Bluetooth Special Interest Group (SIG) revealed the specifications of upcoming Bluetooth 4.0. The transfer rate offered by Bluetooth 4.0 will be around 1Mbps, and it will transmit data at 2.4Ghz frequency.

Michael Foley, Ph.D., executive director of Bluetooth SIG said With today’s announcement the race is on for product designers to be the first to market. Bluetooth low energy modules for all sorts of new products may now be qualified this is an important step towards our goal of enabling new markets with Bluetooth wireless technology. For example, the Continua Health Alliance has already selected Bluetooth low energy technology as a transport for the next version of its guidelines.

Bluetooth 4.0 will see the implementation of bluetooth technology in many fields which we have not even imagined until now like Medical, Healthcare, Sports and Fitness etc. Today’s news from the Bluetooth SIG is an exciting step forward for technology in mobile health and wellness devices,said Rick Cnossen, president and board chair, Continua Health Alliance. Our selection of Bluetooth low energy for the Continua Version Two Design Guidelines extends exciting new capabilities to manufacturers and consumers alike, as well as enabling additional use cases within the Continua ecosystem.”

Bluetooth 4.0 features two types of implementation single mode and dual mode. Single mode chip features a link layer providing very low idle power consumption. On the other hand, the dual mode chip can be integrated into an old bluetooth controller. This will allow manufacturers to save cost to a certain extent. and still be able to provide the low power consumption offered by Bluetooth 4.0. The security has also been beefed up to full AES-128 encryption using CCM.

Nokia has been committed to this ultra low power wireless technology since its Wibree technology development. Now we are happy to see the adoption of the Bluetooth low energy specification, which will open up new market opportunities and space to innovate for the industry. The wide manufacturer base behind Bluetooth low energy technology and the combined industry effort will result in exciting new user experiences in the mobile space,said Markku Verkama, Director, Devices R&D Nokia.
