A Brief History of Bluetooth
Before we dive into the specifics of Bluetooth 5.0, it’s essential to understand the origins of this technology. Bluetooth was first introduced in 1998 by a team of engineers at Ericsson, led by Jaap Haartsen and Sven Mattison. The name “Bluetooth” was inspired by the 10th-century Danish king, Harald Blåtand, who was known for his ability to unite warring factions. The Bluetooth logo is a combination of the runes for the letters “H” and “B,” which are the initials of Harald Blåtand’s name in Old Norse.
The first version of Bluetooth, 1.0, was released in 1998, and it had a data transfer rate of 721 kilobits per second (kbps). Over the years, Bluetooth has undergone several updates, with each new version offering improved performance, range, and functionality. Some notable milestones in the evolution of Bluetooth include:
- Bluetooth 2.0, released in 2004, which introduced Enhanced Data Rate (EDR) and increased the data transfer rate to 3 megabits per second (Mbps)
- Bluetooth 3.0, released in 2009, which introduced High Speed (HS) and increased the data transfer rate to 24 Mbps
- Bluetooth 4.0, released in 2010, which introduced Low Energy (LE) and enabled low-power applications
