Bluetooth technology was created in 1994 as a wireless alternative to data cables, exchanging data using radio transmissions between 2402-2480 MHz. A Bluetooth master device can communicate with up to seven devices in an ad-hoc piconet network. Named after the Danish king who united factions, Bluetooth was created as an open standard to allow connectivity between different products and industries.

4. Created in 1994, Bluetooth®
technology was conceived as a
wireless alternative to data cables
by exchanging data using radio
transmissions. The name Bluetooth
came from a tenth century Danish
King, Harald Blåtand or, in English,
Harold Bluetooth. As the story
goes, King Blåtand helped unite
warring factions in parts of what
are now Norway, Sweden and
Denmark. Similarly, Bluetooth
technology was created as an
open standard to allow connectivity
and collaboration between
disparate products and industries.
