Definition:
This technology achieves its goal by embedding tiny, inexpensive, short-range transceivers into the mobile devices that are available today, either directly or through an adapter device such as a PC Card. Bluetooth uses FHSS-Frequency Hopping (79 different frequencies) Spread Spectrum technology in the 2.4 GHZ (giga Hertz) frequency range with 1 Watt (though most devices are 100 miliwatts - 1/10 of 1 Watt) power transmitters as regulated by the FCC-Federal Communications Commission rules. Typical performance levels of Bluetooth systems range from 720 KBPS to 22 MBPS (mega bits per second) at a range of 100-250 feet based on FHSS-Frequency Hopping Spread Spectrum technology - see TECHtionary Wi-Fi-802.11b. Please note speeds may soon reach 100 MBPS (called Wi-Fi-5 a competing standard) in the 5 GHZ frequency range.
