Here is the breakdown of how Bluetooth came to be:
The Inventor: Jaap Haartsen at Ericsson developed the core radio technology to replace wired connections between mobile phones and headsets.
The Partnership: While Ericsson pioneered the technology, they realized a universal standard required industry cooperation. In 1998, the Bluetooth Special Interest Group (SIG) was formed by five companies: Ericsson, IBM, Intel, Nokia, and Toshiba.
IBM's Contribution: IBM contributed significantly to the project, particularly regarding the logical layer and the push for an open, royalty-free standard (RANDZ).
The Name: The name "Bluetooth" was actually proposed by Jim Kardach of Intel, not IBM or Ericsson, based on a Viking king, though Ericsson engineers were involved in the brainstorming.
Therefore, Bluetooth was a collaborative effort initiated by Ericsson, with IBM playing a crucial role in its standardization and development.
