With such a common tech word like Bluetooth, have you ever thought to yourself where it actually came from?
Bluetooth is a technological term that refers to a standard used for exchanging data between a number of devices, both fixed and mobile over relatively short distances. It works by using UHF radio waves, with frequencies ranging from 2.402 GHz to 2.480 GHz.
Bluetooth originates far back in time, a time way before any mobile phone or portable device. In fact, far before electricity!
In the year 920AD, a ruthless Viking ruler by the name Harold I of Denmark, who was also nicknamed Bluetooth, parted with his wicked ways and later converted to Christianity. At the time, Denmark was split into different lands and territories, each under the power of their respective rulers. It was Harold's exceptional skills of both military and diplomatic campaigns that crowned him King. Harold "Bluetooth" would inevitably go down in history as the king who united the separate states of Denmark into a unified territory.
In the late 1990s, mobile engineers developed a system that would also unite the connectivity of computer and cellular industries. Bluetooth was the codename given.
