The definition of Bluetooth.



Bluetooth is named after King Harald Blatan of Denmark, a Viking king who united tribes and was known for his bridge-building projects, not to mention his blue teeth.

Using the unlicensed 2.4-GHz band, Bluetooth changes its signal 1600 times a second using a frequency hopping spread spectrum (FHSS) technique. This allows its multidirectional radio waves to transmit data through walls and other non-metal services at speeds of 720 Kbps within a range of 30 feet and up to 300 feet with a power boost. Expect its data transmission speeds to decline if it experiences any sort of interference from other devices.

Bluetooth won't hit its stride until it starts to operate in gadgets and appliances -- not just PCs. Visit Bluetooth.com to learn more.
