The Bluetooth Special Interest Group (SIG) is developing a method of radio substitution that is designed to allow Bluetooth protocols, profiles, security and pairing to be used in consumer devices while achieving faster throughput with the momentary use of a secondary radio present in the device.
SIG member companies are working on the specification for the architecture, which is called alternate media access control (MAC)/PHY.
In 2006, the Bluetooth SIG announced the selection of the WiMedia Alliance brand of ultra-wideband (UWB) technology as a high-speed channel for Bluetooth technology.
This development work continues between the two organizations in advance of UWB technology adoption expected to be colocated in many Bluetooth devices, said the Bluetooth SIG.
In the meantime, the SIG will make use of the Institute of Electrical and Electronics Engineers (IEEE) 802.11.
This two-phased roadmap for higher speeds is designed to allow Bluetooth devices to use IEEE 802.11 while the SIG continues preparations for the presence of UWB in the future, said the Bluetooth SIG.
With the availability of Bluetooth technology, device users can move data between devices without the need for cables and wires, according to the Bluetooth SIG.
Some applications consumers will experience with this specification include being able to:
- Wirelessly bulk synchronize music libraries between a PC and MP3 player.
- Bulk download photos to a printer or PC.
- Send video files from a camera or phone to a computer or television.
The core specification enabling the Alternate MAC/PHY is expected to be published in mid-2009, said the Bluetooth SIG.
