BluetoothLow energy Bluetooth wireless specification : The Bluetooth Special Interest Group (SIG) announced the adoption of Bluetooth wireless technology, which is the hallmark feature of the Bluetooth Core Specification Version 4.0. As an enhancement, Bluetooth low energy technology opens entirely new markets for devices requiring low cost and low power wireless connectivity with this evolution in Bluetooth wireless technology that will enable a plethora of applications - some not even possible or imagined today. Many markets such as healthcare, sports and fitness, security, and home entertainment will be enhanced with the availability of small coin-cell battery powered wireless products and sensors now enabled by Bluetooth wireless technology.

Bluetooth wireless technology make new markets possible
“With this announcement the race is on for product designers to be the first to market,” said Michael Foley, Ph.D., executive director, Bluetooth SIG. “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.”

Adaption of low energy Bluetooth wireless increases opportunities for Nokia
“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.

Bluetooth wireless specification enhances development of new devices
This enhancement to the Bluetooth Core Specification allows two types of implementation, dual-mode and single-mode. In a dual-mode implementation, Bluetooth low energy functionality is integrated into an existing Classic Bluetooth controller. The resulting architecture shares much of Classic Bluetooth technology’s existing radio and functionality resulting in a minimal cost increase compared to Classic Bluetooth technology. Additionally, manufacturers can use current Classic Bluetooth technology (Bluetooth V2.1 + EDR or Bluetooth V3.0 + HS) chips with the new low energy stack, enhancing the development of Classic Bluetooth enabled devices with new capabilities.

Transmissions with help of Bluetooth wireless
Single-mode chips, which will enable highly integrated and compact devices, will feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost. The Link Layer in these controllers will enable Internet connected sensors to schedule Bluetooth low energy traffic between Bluetooth transmissions.

Bluetooth wireless technology in Telehealth Solutions
This announcement also advances the requirements of the Bluetooth SIG’s agreement with Continua Health Alliance, the industry coalition of leading health care and technology companies charged with establishing a system of interoperable personal telehealth solutions. Continua has voted to include the Bluetooth low energy wireless technology specification, Bluetooth low energy technology, in Version Two of its Continua Health Alliance Design Guidelines. The selection of Bluetooth low energy technology extends the current Continua standard for the Bluetooth Health Device Profile, the only wireless technology specification included in Continua’s Version One Design Guidelines.
