What is Bluetooth? Bluetooth® is a wireless standard initiated by Ericsson with the aim of developing a wireless alternative for connecting cell phones and accessories. The radio technology is standardized as 802.15.1 by the IEEE (Institute of Electrical and Electronic Engineers). Behind Bluetooth is the Bluetooth Special Interest Group (SIG) (www.bluetooth.com), a consortium of currently over 2,000 companies. The radio technology supports synchronous data transmission, as required for voice applications, as well as asynchronous transmission, the latter in a symmetrical or asymmetrical mode. The data width is currently a maximum of around 3 Mbit per second; higher data rates of up to 100 Mbit/s are planned for the future. Bluetooth devices use the license-free ISM band (Industrial, Scient.
