He firstly worked at Ericsson USA in the Advanced Mobile Communications Systems BU and then at Ericsson Sweden in the Mobile Terminal BU, where he was tasked with finding solutions for short-range radio connections, at distances of around 3 to 4 meters. While Dr.Haartsen was working initially alone, then he recruited a team of skilled people. In 1995 the co-researcher Sven Mattisson joint the Haartsen‘s team, which grew from 5 to 15 people. During a trip in Canada the co-researcher Jim Kardach and Mattisson changed the development codename of the project from Multi Communicator Link to Bluetooth. The name Bluetooth was born from the fascination for the danish king Harald Blatant which joined the Kingdom of Denmark and the Norway. As different cultures and religions united the people in the 10th century well as the Bluetooth are connecting different electronic devices (mobile phone, printers, pc, headphones).

Therefore the team had a workable solution by 1997 and the parent company realized it needed to collaborate with other firms since Ericsson was only a Mobile Phone producer. In 1998, five founding members composed the Bluetooth Special Interest Group (SIG): Ericsson, Nokia , Intel, Toshiba and IBM. The Bluetooth project was born in 1994 as research project then Haartsen‘s team patented it only in 1997. In 2002 the Bluetooth became an IEEE STANDARD, the 802.15.1. In 2008 after 10 years from the birth, the number of connected devices was around 10,000 units.
