How Bluetooth Gets its

Bluetooth is named after King Harald Bluetooth who united  Scandinavia into a single kingdom. The logo is his initials HB written in old Nordic runes.

Bjarkan + Haglaz =



H rune or *Haglaz * 




B rune or *Bjarkan*



In 1996 a number of companies were looking to standardize the industry around a short-range radio link for doing a number of things which seem obvious today (not so obvious in 1996). 


Within Intel, I had started a program called Business-RF; Ericsson had a program called MC-Link; Nokia had a program called Low Power RF. At the time we were in discussions to figure out the best way to drive a single wireless standard in the industry in order to prevent fragmentation of technologies in this area (remember that in 1996 nothing existed). 


As we would approach different companies to talk about what short range wireless technologies could do and how having a single short-range standard would be so much better than having three or more competing and fragmenting standards, it became apparent the need to have a single name; as Intel would talk to people about "Biz-RF," Ericsson about "MC-Link" and Nokia about "Low Power-RF," which also created confusion. 


In December of 1996 we figured we had the right mixture of companies to be successful in driving the technology through a Special Interest Group (SIG) and met in Lund, Sweden at the Ericsson plant to get final agreement on forming the SIG. 


At this time, Intel proposed that the SIG be called by the "codename" Bluetooth until the SIG's marketing group would come up with a formal technology name. When asked about the name Bluetooth, I explained that Bluetooth was borrowed from the 10th century, second King of Denmark, King Harald Bluetooth; who was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link. 


Where did I hear about the name Bluetooth? This originated on an earlier business trip to Toronto, Canada where Ericsson's Sven Mathesson and I were presenting our technology proposal to an existing SIG; Sven pitching as MC-Link, and me pitching as Biz-RF. 


After having our proposal firmly rejected, we went on a pub crawl through wintrily, blustery Toronto. Being a big history fan, I would trade stories of history with Sven. 


Now Sven knew lots about radios, but not too much about history, but he had read this book (which at a later date he gave me a copy) called the Longships by Frans G. Bengtsson and would relate the history through this story. 


In this book a couple of Danish warriors travel the world looking for adventure, and the king during this time was Harald Bluetooth. 


When I got home from this business trip, a history book I had ordered called the The Vikings by Gwyn Jones" had arrived. Thumbing through the book, I found this (see Figure 2) picture of a giant rock, or runic stone, which depicted the chivalry of Harald Bluetooth, the guy which Sven just told me about! 


Reading further, the book indicated that King Harald had this memorial made for Gorm his father and Thyri his mother: that Harald who won for himself all Denmark and Norway, and made the Danes Christian."
