BLUETOOTH

Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmission over short distances from fixed and / or mobile devices, creating wireless Personal Area Networks (PANs). The intent behind the development of bluetooth was the creation of single digital wireles protocol, capable of connecting multiple devices and overcoming issues arising from syncronization of these devices. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, GPS receivers, digital cameras, and video games consoles over a secure, globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency bandwith. The bluetooth specifications are developed and licensed by Bluetooth Special Interest Group (SIG). The Bluetooth SIG consist of companies in the areas of telecommunication, computing, networking, and consumer elektronic.

The Original the name and the logo

Bluetooth was named after a tenth-century king, Harald Bluetooth, King of Denmark and Norway. Bluetooth is an anglicized version of harald blaatand, who was known for his unification of previously warring tribes from Denmark (including now Swedish Scania, where the bluetooth technology was invented), and Norway. Bluetooth likewise was intended to unify different technologies, such as personal computers and mobile phones.
The name may have been inspired less by the historical Harald than the loose interpretation of him in The Long Ships by Frans Gunnar Bengtsson, Swedish Viking-inspired novel.
The Bluetooth logo merges the Germanic Runes analogous to the modern latin letter H and B; (for Harald Bluetooth) Hagall and Berkanan; merged together, forming a bind rune.
