When Was Bluetooth Invented?
Bluetooth technology was invented in the mid-1990s, with the initial work commencing in 1994. Ericsson’s mobile terminals division initiated the project to develop wireless headsets. The rollout of the first Bluetooth-enabled device occurred in 1999; it was a hands-free mobile headset.
The Bluetooth Special Interest Group (SIG), the body that oversees the development and licensing of Bluetooth technologies, was subsequently formed in 1998. This consortium, initially comprising Ericsson, IBM, Intel, Nokia, and Toshiba, has grown to include hundreds of leading tech companies worldwide. It continues to oversee the development of Bluetooth standards and licensing Bluetooth technologies to manufacturers.
From its inception in the mid-90s, Bluetooth has seen various versions, each introducing new features and improvements over its predecessors. These advances range from enhanced speed to lower power consumption and extended range.
Why is Bluetooth Called Bluetooth?
The name “Bluetooth” traces its roots back to Scandinavian history. During the 10th century, a Danish king named Harald “Bluetooth” Gormsson was known for uniting Denmark and part of Norway into a single kingdom. His ability to unify inspired the naming of this technology, designed to bring together a wide range of devices through wireless communication.
The Bluetooth logo also stems from Harald’s initials, represented as “H” and “B” in the ancient rune alphabet. The choice to attach the technology’s identity to King Harald Bluetooth signified the inventors’ aspiration to replicate the unity King Harald achieved during his reign in the realm of digital technology.
How Does Bluetooth Work?
Bluetooth operates on radio frequency, specifically the 2.4 GHz band, which is globally accessible and free of charge. The technology uses a Frequency Hopping Spread Spectrum (FHSS) protocol. This protocol enables the devices to hop from one frequency to another within the 2.4 GHz band, making Bluetooth exceptionally good at avoiding interference.
Bluetooth devices create ad-hoc networks known as piconets. When two devices connect, they form a master-slave relationship, where the master device dictates the communication rules. The master can link to seven active slave devices within its piconet, and many of these piconets can coexist in the same area, forming a kind of “scatternet.”
Each Bluetooth device can communicate on 79 frequencies within the 2.4 GHz range, changing frequencies or “hopping” 1600 times per second. By rapidly switching among these frequencies, Bluetooth devices can avoid interference from other devices or electromagnetic noise in the environment.
Integration of Bluetooth in Mobile and Electronic Devices
As Bluetooth technology developed, its integration into mobile phones and other electronic devices became a game-changer in the tech industry. Mobile devices, from smartphones to tablets, quickly adopted Bluetooth, making it a standard data exchange and connectivity feature. The ubiquitous presence of Bluetooth in mobile phones allowed for a seamless and cable-free exchange of information, including contacts, media files, and even internet access via tethering.
