A Brief History of Bluetooth

Bluetooth began in 1994 when Ericsson, a Swedish telecommunications company, started researching ways for mobile phones to communicate with each other and with computers. In 1998, Ericsson joined forces with Intel, IBM, Toshiba, and Nokia to form the Bluetooth Special Interest Group (SIG) to develop standards for short-range wireless connectivity.

The name “Bluetooth” comes from Harald Blåtand, a 10th-century Scandinavian king who united Denmark and Norway. The implication was that Bluetooth technology would join devices like this ancient king, who united differing nations.

The first Bluetooth specification was released in 1999, allowing connectivity within a range of 10 meters. This was extended to 100 meters in the updated 1.2 specification released in 2003. Over the years, the SIG has updated Bluetooth standards for faster data transfer speeds and enhanced capabilities.

How Does Bluetooth Work?

Bluetooth uses short-wavelength UHF radio waves in the industrial, scientific, and medical radio bands between 2402 and 2480 MHz to transmit data wirelessly over short distances.

Bluetooth communication has two main components: the controller and agent devices. The controller device initiates and controls the connection by sending signals and determining frequency hopping patterns. Meanwhile, the agent device synchronizes with the master’s address and clock, staying locked to the controller device’s phase and frequency hopping sequence.

Bluetooth uses spread spectrum frequency hopping, meaning the transmitter switches frequencies up to 1600 times per second across 79 designated Bluetooth channels to avoid interference. Bluetooth will hop over if a particular band is already in use. This adaptive frequency hopping allows Bluetooth to minimize interference with other wireless technologies sharing its spectrum.
