This is due to the increased global demand for Bluetooth-enabled devices. The arrival of Bluetooth 2.0 marked a period of significant growth. And understandably so since, at the time, Bluetooth was primarily meant for calls rather than music. Implemented Extended Synchronous Connections (eSCO) for improved voice qualityĭespite the improvements, Bluetooth 1.2 didn’t have enough bandwidth to transmit high-quality audio.Improved Adaptive Frequency Hopping (AFH) which lessened signal interferences.Quicker device discoverability and pairing.

Version 1.2 improved on this by increasing the data transfer speed to 1 Mbps. Main featuresīluetooth 1.0a and 1.0b featured peak data transfer speeds of around 732.2 kb/s, with a connection range of 10m or 33ft. Some of these are wireless headsets, mobile phones, laptops, cars, and digital cameras. In the succeeding years, Bluetooth 1.2 was eventually integrated into different devices. This was widely used for connecting PC peripherals like modems and printers. Here’s a quick look at the different Bluetooth versions throughout the years.īluetooth was designed to replace the RS-232 computer serial port. The first version was eventually standardized in 1994 by Jaap Haartsen, an engineer and researcher at the same company. The development of Bluetooth technology was initiated by Ericsson Mobile CTO Nils Rydbeck in 1989. The king was nicknamed “Blue tooth” on account of a single rotting tooth in his mouth that was bluish-gray.Īccording to the founders of Bluetooth SIG, the name was meant to be temporary until the team could think of something “cooler”. The name “ Bluetooth” was taken from King Harald “Blåtand” Gormsson, a Danish king known for uniting Denmark and Norway.
