When two Bluetooth enabled devices are in communication range of one another, a link is instantly established. Each gadget has a small radio transceiver that transmits and receives signals, and Bluetooth uses radio waves to transport data between them. The standard outlines the technical requirements that devices must adhere to in order to communicate with one another. The Bluetooth Special Interest Group (SIG), a collection of businesses that have agreed to use and promote Bluetooth technology, is responsible for defining the Bluetooth standard. Since then, a number of improved Bluetooth specifications have been made available, each of which offers enhancements to speed, range, and power usage. It had a range of up to 10 metres and a maximum data rate of 1 Mbps. In 1999, Bluetooth 1.0, the initial iteration of the Bluetooth protocol, was made public. He created a low-power wireless device that could function in the unlicensed 2.4 GHz ISM (Industrial, Scientific, and Medical) frequency band by drawing on his skills in radio technology and digital signal processing. Haartsen's system was to link wireless headphones to cell phones. Bluetooth removes the need for connections between devices by using short-range radio waves to transmit data between them. The purpose of Bluetooth was to develop a wireless communication system that could eliminate the requirement for cables for connecting various electronic devices, including cell phones, computers, and other gadgets. He was employed by the Mobile Platforms division of Ericsson in the Lund City of Sweden. Jaap Haartsen was principally in charge of developing Bluetooth. The Swedish multinational telecommunications corporation Ericsson invented and patented Bluetooth technology in 1994. It provides quicker data transmission rates, longer battery life, and greater privacy features. In 2021, Bluetooth 5.3, the most recent version of the technology, was introduced. Bluetooth technology has developed over time. Newer versions of Bluetooth technology enable quicker data transmission rates, greater range, and increased security.
