History of Computers - Bluetooth
Page created by Ian Thakur.
Bluetooth is the global communication standard that connects two devices, usually a phone and audio device, using short length radio waves rather than cords. Bluetooth was invented in 1994 by Ericsson, a Swedish Company founded in Stockholm, Sweden in 1876. The Bluetooth Special Interest Group has managed Bluetooth standardization since 1998.

Overview
Bluetooth uses short length radio waves to transmit information between devices rather than using cords to transmit this information. Bluetooth was invented in 1994 by Ericsson, a Swedish Company founded in Stockholm, Sweden in 1876. The first cell phone to implement Bluetooth technology was the Ericsson R520M, which launched in 2002[1]. Bluetooth is currently managed by the Bluetooth Special Interest Group (SIG), a non-profit coalition of 25,000+ companies, established in 1998. This coalition standardizes Bluetooth settings so that Bluetooth devices are compatible with a multitude of phones, computers, cars, and gaming consoles. Notable members of SIG include Ericsson, Apple, and Microsoft[2]. Bluetooth's range is usually less than 10 meters; however, some devices have Bluetooth capabilities exceeding 100 meters. Bluetooth got its name from King Harald "Bluetooth" Gormsson, a Danish king who unified a few Danish tribes into a kingdom[3].
Significance
Bluetooth technology created an alternative method for transmitting audio, and later video, between a broadcaster and a receiver. Prior to the invention of Bluetooth broadcasters could only transmit audio and video via cords; however, with the invention of Bluetooth a broadcaster, such as a phone, could transmit audio, and later video, to receivers, such as speakers and televisions. Recently, Apple announced that it is removing the headphone jack from their iPhone devices leading many to believe that wired audio connections will become obsolete in the near future. Rather than using wired connections, experts predicts that phones will require Bluetooth connections for devices such as headphones and Speakers [4].
