SIG INTRODUCESBLUETOOTHLOW ENERGY WIRELESS TECHNOLOGY, THE NEXT GENERATION OF BLUETOOTH WIRELESS TECHNOLOGY

Formal Adoption of Specification Enhancement Opens Doors to New Market Creation in Healthcare, Fitness, Security and Home Entertainment

BELLEVUE, WA – December 17, 2009– The Bluetooth Special Interest Group (SIG) today announced the adoption ofBluetooth®low energy wireless technology, which is the hallmark feature of theBluetoothCore Specification Version 4.0.  As an enhancement to the specification,Bluetoothlow energy technology opens entirely new markets for devices requiring low cost and low power wireless connectivity with this evolution inBluetoothwireless technology that will enable a plethora of new 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 byBluetoothwireless technology.

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

“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 ofBluetoothlow 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."

“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 theBluetoothlow energy specification, which will open up new market opportunities and space to innovate for the industry. The wide manufacturer base behindBluetoothlow 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.

Bluetoothlow energy wireless technology, the hallmark feature of the v4.0BluetoothCore Specification, features:

• Ultra-low peak, average and idle mode power consumption
• Ability to run for years on standard coin-cell batteries
• Low  cost
• Multi-vendor interoperability
• Enhanced range

This enhancement to theBluetoothCore Specification allows two types of implementation, dual-mode and single-mode. In a dual-mode implementation,Bluetoothlow energy functionality is integrated into an existing ClassicBluetoothcontroller. The resulting architecture shares much of ClassicBluetoothtechnology’s existing radio and functionality resulting in a minimal cost increase compared to ClassicBluetoothtechnology.  Additionally, manufacturers can use current ClassicBluetoothtechnology (BluetoothV2.1 + EDR orBluetoothV3.0 + HS) chips with the new low energy stack, enhancing the development of ClassicBluetoothenabled devices with new capabilities.

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 scheduleBluetoothlow energy traffic betweenBluetoothtransmissions.

Technical Details

• Data Transfers–Bluetoothlow energy technology supports very short data packets (8 octet minimum up to 27 octets maximum) that are transferred at 1 Mbps. All connections use advanced sniff-subrating to achieve ultra low duty cycles.

• Frequency Hopping–Bluetoothlow energy technology uses the adaptive frequency hopping common to all versions ofBluetoothtechnology to minimize interference from other technologies in the 2.4 GHz ISM Band. Efficient multi-path benefits increase the link budgets and range.

• Host Control–Bluetoothlow energy technology places a significant amount of intelligence in the controller, which allows the host to sleep for longer periods of time and be woken up by the controller only when the host needs to perform some action.  This allows for the greatest current savings since the host is assumed to consume more power than the controller.

• Latency

  – Bluetoothlow energy technology can support connection setup and data transfer as low as 3ms, allowing an application to form a connection and then transfer authenticated data in few milliseconds for a short communication burst before quickly tearing down the connection. 

• Range– Increased modulation index provides a possible range forBluetoothlow energy technology of over 100 meters.

• Robustness–Bluetoothlow energy technology uses a strong 24 bit CRC on all packets ensuring the maximum robustness against interference.

• Strong Security– Full AES-128 encryption using CCM to provide strong encryption and authentication of data packets.

• Topology–Bluetoothlow energy technology uses a 32 bit access address on every packet for each slave, allowing billions of devices to be connected.The technology is optimized for one-to-one connections while allowing one-to-many connections using a star topology. With the use of quick connections and disconnections, data can move in a mesh-like topology without the complexities of maintaining a mesh network. 

Bluetooth

Technology in Telehealth Solutions

Today’s 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 theBluetoothlow energy wireless technology specification,Bluetoothlow energy technology, in Version Two of its Continua Health Alliance Design Guidelines. The selection ofBluetoothlow energy technology extends the current Continua standard for theBluetoothHealth Device Profile, the only wireless technology specification included in Continua’s Version One Design Guidelines.

AboutBluetooth® Wireless Technology

Bluetoothwireless technology is the global short-range wireless standard for personal connectivity of a broad range of electronic devices. The technology continues to evolve, building on its inherent strengths – small-form factor radio, low power, low cost, built-in security, robustness, ease-of-use, and ad hoc networking abilities. This evolution now provides manufacturers and consumers with three options for connecting wirelessly – ClassicBluetoothtechnology for use in a wide range of consumer electronics;Bluetoothhigh speed technology for the transfer of video, music and photos between phones, cameras, camcorders, PCs and TVs; andBluetoothlow energy technology for low power sensor devices and new web services within the healthcare, fitness, security, home entertainment, automotive and automation industries. More than eight newBluetoothenabled products are qualified every working day and more than 19 millionBluetoothunits are shipping per week. There are nearly three billionBluetoothdevices in the marketplace and that number climbs daily, making it the only proven wireless choice for developers, product manufacturers, and consumers worldwide.

 AboutBluetoothlow energy Wireless Technology

Bluetoothlow energy technology is a new low energy enhancement to theBluetoothwireless technology Core Specification that paves the way to a vast new market for watches, remote controls, and healthcare and sports sensors.
