who invented bluetooth

Bluetooth technology was invented by Jaap Haartsen, a Dutch electrical engineer. He developed the specification for Bluetooth while working at Ericsson Mobile Terminal Division in Lund, Sweden, starting in 1994. Haartsen's work involved creating a short-range radio technology that enabled wireless communication between devices using UHF radio waves at 2.4 GHz with frequency hopping techniques to ensure reliability and low energy consumption. He played a key role in the creation of the Bluetooth Special Interest Group (SIG) in 1998, which manages Bluetooth standards and licensing. Haartsen's invention has become a global standard used in billions of devices worldwide
