How a medieval king influenced a modern technology
Digest
This episode of Tech Stuff delves into the fascinating history of Bluetooth technology. The episode begins by revealing the unexpected origin of the name: King Harold Gormson, a medieval Danish king known for his bad tooth, which gave him the nickname "Bluetooth." The episode then explores the development of Bluetooth technology, starting with Dr. Hartson's work at Ericsson in the 1990s, where he experimented with short-range wireless transmissions in the 2.4 gigahertz band. The episode highlights the challenges faced by the Bluetooth Special Interest Group (SIG) in finding a suitable name for the technology, ultimately settling on the code name "Bluetooth." The episode then traces the evolution of Bluetooth standards, from the initial Bluetooth 1.0, which was limited in range and data bandwidth, to the modern-day Bluetooth 5.4, which offers improved range, bandwidth, and energy efficiency. The episode concludes by emphasizing the importance of Bluetooth technology in today's world, particularly in the realm of wireless communication and the Internet of Things.

Keywords
Bluetooth
Bluetooth is a wireless communication technology that allows devices to connect and exchange data over short distances. It is widely used in a variety of devices, including smartphones, laptops, headphones, speakers, and smart home appliances. Bluetooth technology is based on the use of radio waves in the 2.4 gigahertz band, which allows for short-range communication between devices. The name "Bluetooth" is derived from the nickname of King Harold Gormson, a medieval Danish king known for his bad tooth.
King Harold Gormson
King Harold Gormson was a medieval Danish king who ruled from 958 to 986 AD. He was known for his efforts to unite Denmark and Norway, and for his bad tooth, which gave him the nickname "Bluetooth." The nickname "Bluetooth" was later adopted as the name for the wireless communication technology.
SIG
SIG stands for Special Interest Group. In the context of Bluetooth technology, SIG refers to the Bluetooth Special Interest Group, a consortium of companies that develops and promotes the Bluetooth standard. The SIG is responsible for setting the specifications for Bluetooth technology, ensuring interoperability between devices, and promoting the adoption of Bluetooth technology.
Wireless Communication
Wireless communication refers to the transmission of information between devices without the use of physical cables. Bluetooth is a type of wireless communication technology that uses radio waves to transmit data over short distances. Other types of wireless communication technologies include Wi-Fi, cellular networks, and satellite communication.
Internet of Things (IoT)
The Internet of Things (IoT) refers to the network of physical devices, vehicles, buildings, and other objects that are embedded with sensors, software, and network connectivity, allowing them to collect and exchange data. Bluetooth technology is often used in IoT applications, particularly for devices that require short-range communication and low power consumption.
Q&A
What is the origin of the name "Bluetooth"?
The name "Bluetooth" comes from the nickname of King Harold Gormson, a medieval Danish king known for his bad tooth. The nickname was chosen because King Harold Gormson was known for uniting Denmark and Norway, just as Bluetooth technology aims to unite different devices.
How did Bluetooth technology evolve over time?
Bluetooth technology has evolved significantly since its inception in the 1990s. Early versions of Bluetooth were limited in range and data bandwidth, but later versions have introduced improvements in range, bandwidth, security, and energy efficiency. The introduction of Bluetooth Low Energy (LE) in 2013 has made Bluetooth technology ideal for use in wearables and other devices with small batteries.
What are some of the key applications of Bluetooth technology today?
Bluetooth technology is widely used in a variety of devices, including smartphones, laptops, headphones, speakers, and smart home appliances. It is also used in many Internet of Things (IoT) applications, particularly for devices that require short-range communication and low power consumption.
What are some of the challenges that the Bluetooth Special Interest Group (SIG) faced in developing Bluetooth technology?
One of the biggest challenges faced by the SIG was finding a suitable name for the technology. The SIG considered several names, including "Personal Area Networking" and "Radio Wire," but ultimately settled on the code name "Bluetooth." The SIG also had to address concerns about security and interoperability between devices.
Show Notes
King Harald of Denmark had a little quirk that would, centuries later, provide inspiration for the naming of a modern technology. We learn how his lack of oral hygiene led to the naming of a wireless protocol.
