Bluetooth is the cable-killer technology originally
developed by Ericsson of Sweden (named after Harold Bluetooth the Nordic
king who united Scandinavia) that enables seamless voice and data transmission
through wireless, short-range unlicensed radio links. The open specification
is supported by the Bluetooth Special Interest Group, comprised (at last
count) of 2,074 contributing member companies, and is being standardized
under IEEE 802.15. (Coincidentally, Part 15 is the section of FCC regulation
addressing unlicensed radio operation!)
Originally conceived as a simple wire replacement technology, Bluetooth
now offers the specter of personal area networks, and through the use of cell
phones as terminals, for example (more than 400 million sold last year alone),
a portal to talking to every device in you immediate vicinity.
