To avoid having to license radio spectrum, Bluetooth has been designed to take advantage of the 2.4 GHz band, also known as the Industrial, Scientific, and Medical band (ISM). The band covers the frequencies 2400 MHz to 2483.5 MHz and was not originally designated for use in communications. However, various governments have taken to licensing certain frequencies within the band, with France being an interesting case as it has used part of the spectrum for military communications.
If most of you may recall, the initial hype surrounding the single-chip radio networking concept dubbed Bluetooth said that we would be seeing a multitude of applications during the year 2000. Everything from smart coffee machines to smart zambonis - yes, Bluetooth would be there.
Needless to say, hype is a bright but mostly short-lived flame. During this year, manufacturers that have focused on the Bluetooth technology have had to deal with issues such as device interoperability and the cost of chips which are still high. The recent Comdex show had plenty of gadgets based on Bluetooth but they have yet to be shipped and will most likely remain that way until well into the next year.
