<strong>Bluetooth</strong> Characteristics (II)<br />
Uses 79 channels in the frequency range 2.402 - 2.480 GHz<br />
Uses Frequency Hop Spread Spectrum (FHSS) to avoid<br />
interference<br />
Transmitter hops between available frequencies according to specified<br />
algorithm<br />
Transmitter operates in sync with receiver<br />
A short burst of data is transmitted on a narrowband<br />
Transmitter then tunes to another frequency and transmits again -<br />
capable of hopping its frequency over a given bandwidth several times a<br />
second<br />
Requires much wider bandwidth than required to transmit the same<br />
information using one carrier frequency
