“High Speed Bluetooth,” a new combination of Wi-Fi (802.11) and Bluetooth technologies, is certain to benefit users who transfer large multimedia files between wireless devices such as cellular handsets, according to a new Research Brief from ABI Research.

“Bluetooth penetration in cellular handsets is at an all-time high,” says senior analyst Douglas McEuen. “But it has a short range and fairly low data transfer capabilities. Users’ growing desire to share pictures, audio, and video makes demands on Bluetooth that it was never designed to handle.” So the Bluetooth Special Interest Group has announced a technology – “High Speed Bluetooth” – that hands off transmissions of large data files (such as multimedia) to the faster 802.11 radios that are increasingly found in the same Bluetooth-equipped devices. When that extra throughput is no longer needed, Bluetooth automatically takes over again, resulting in power savings.

The first iteration of the new technology will be a software upgrade that will allow the two existing radios to work together. Later, some come companies will attempt to put both radios in one package or on one chip.

“High Speed Bluetooth is a logical step that takes advantage of existing building-blocks,” says McEuen. “For consumers it’s a win, because the upgrade is totally transparent to them. They’ll just see better data throughput and faster file transfers.”

But don’t expect to add High Speed Bluetooth to your existing mobile phone, even if it has Wi-Fi as well. The software upgrade will debut in new handsets and other devices expected to appear late in 2008.

The industry is getting on board, too. At least two chipmakers, Texas Instruments and CSR, are working on the software upgrade, and handset OEMs will be able to incorporate High Speed Bluetooth easily and economically.

	Maximum Permitted Power mW(dBm)	Range (approximate)
Class 1	100 mW (20 dBm)	~100 meters
Class 2	2.5 mW (4 dBm)	~10 meters
Class 3	1 mW (0 dBm)	~1 meter

In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices.

High-speed Bluetooth

On 28 March 2006, the Bluetooth Special Interest Group announced its selection of the WiMedia Alliance Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) version of UWB for integration with current Bluetooth wireless technology.

UWB integration will create a version of Bluetooth wireless technology with a high-speed/high-data-rate option. This new version of Bluetooth technology will meet the high-speed demands of synchronizing and transferring large amounts of data, as well as enabling high-quality video and audio applications for portable devices, multi-media projectors and television sets, and wireless VOIP.

At the same time, Bluetooth technology will continue catering to the needs of very low power applications such as mice, keyboards, and mono headsets, enabling devices to select the most appropriate physical radio for the application requirements, thereby offering the best of both worlds.

Bluetooth 3.0

The next version of Bluetooth after v2.1, code-named Seattle (the version number of which is TBD) has many of the same features, but is most notable for plans to adopt ultra-wideband (UWB) radio technology. This will allow Bluetooth use over UWB radio, enabling very fast data transfers of up to 480 Mbit/s, while building on the very low-power idle modes of Bluetooth.

Ultra Low Power Bluetooth

On June 12, 2007, Nokia and Bluetooth SIG announced that Wibree will be a part of the Bluetooth specification as an ultra low power Bluetooth technology.^[13] Expected use cases include watches displaying Caller ID information, sports sensors monitoring your heart rate during exercise, as well as medical devices. The Medical Devices Working Group is also creating a medical devices profile and associated protocols to enable this market.
