Instead of creating a local-area network (LAN) or a wide-area network (WAN), Bluetooth creates a personal-area network (PAN) just for you. Cell phones, for example, can be paired with wireless Bluetooth headsets.
When used in tandem with a Bluetooth-enabled cell phone and successfully paired, you can leave your cell phone in your pocket and perform most of your mobile phone’s functions using your in-ear Bluetooth headset.
In addition to being paired with cell phones, short-range Bluetooth technology is also compatible with personal computers, laptops, printers, GPS receivers, digital cameras, telephones, video game consoles and more for various practical functions.
The term Bluetooth was coined after the Danish and Norwegian king Harald Bluetooth Gormson (Harald Blåtand in Danish).
The 10th-century king unified Denmark with Norway. Bluetooth specifications have been made by the Bluetooth Special Interest Group (SIG).
