My wireless speakers, earphones, hands-free calling – what’s the magic behind Bluetooth tech? How does it all work? 

The idea of what we call “Bluetooth” today was first introduced back in 1989. Dr. Nils Rydbeck, who was the chief technology officer at Ericsson Mobile, and inventor Dr. Johan Ullman had this revolutionary idea to develop a pair of wireless headsets. They brought Dr. Jaap Haartsen on to the project. A mere 5 years later, he’d be the engineer who made the breakthrough and came out with the first protocol. 

It took a few more years to perfect the technology. But finally, in 1999, they presented their first hands-free headset to the world at the Comdex computer exposition and trade show in Las Vegas.
