What is Bluetooth?

Bluetooth wireless technology is an open, accepted standard for wireless communication which means that Bluetooth electronic equipment can communicate as long as they are within approx. 10 metres of each other, making it possible to transfer data, speech, music or images without a physical connection. The mobile telephone manufacturer Ericsson invented Bluetooth Today, Bluetooth technology can be found in all types of electronic equipment – including mobile phones, mobile headsets, PCs, keyboards, mouse devices, printers, GPS navigation units, video cameras and pocket PCs – and new products are emerging every day. technology, naming it after the Viking King Harald Bluetooth. Just as King Harald Bluetooth united Denmark and Norway, Bluetooth technology "unites" various types of electronic equipment to form a coherent whole. Ericsson formed the foundation for Bluetooth as early as 1994, but the standard was not ready for use until 1998. The first Bluetooth products came on the market in 2000.

The Story of BlueTooth
The name "Bluetooth" is taken from the 10th century Danish King Harald Blatand - or Harold Bluetooth in English. During the formative stage of the Trade Association a code name was needed to name the effort. Over an evening discussing European history and the future of wireless technology several felt it was appropriate to name the technology after King Blatand. He had been instrumental in uniting warring factions in parts of what is now Norway, Sweden and Denmark - just as the technology is designed to allow collaboration between differing industries such as the computing, mobile phone and automotive markets. The code name stuck.

In Jelling, Denmark a monument can be found in a church yard that celebrates both his achievements and those of his father the first king of Denmark "Gorm the Old". Interestingly this particular stone was lost for nearly six-hundred years after Harald had a small war with his own son, Sven Forkbeard, over control of the country. Sven "won" the argument (exiling his father in the process), and since this runic stone also glorified Harald, Sven had it buried. Only years later a farmer, curious about a large mound in his farm, rediscovered the stone.

The logo itself was originally designed by a Scandinavian firm at the time the trade association was announced to the public. Keeping to the traditions of the name, the logo combines the runic alphabetic characters "H" which looks similar to an asterisk and a "B". Look carefully you can seen both represented in the logo.
