Specifications Different with other wireless standards, the specification of Bluetooth gives product developers both a link layer and application layer definitions, which will help support data and voice applications.

Spectrum The Bluetooth technology operates in the industrial and scientific band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping signal.

Interference The adaptive frequency hopping of Bluetooth technology was designed to reduce interference between wireless technologies that share the 2.4 GHz spectrum.  Adaptive frequency hopping (AFH) works well within the spectrum to take full advantage of the frequency available.

AFH hopping allows for more efficient transmission within the spectrum, which provides users with greater performance even if they  use other technologies along with Bluetooth.
