Bluetooth is a technology standard used to enable short-range wireless communication between electronic devices. Since Bluetooth operates on radio frequencies, rather than the infrared spectrum used by traditional remote controls, devices using this technology do not have to maintain a line of sight to communicate. Its other key features are low power usage and relatively low cost.
What is Bluetooth?
Who developed Bluetooth?
Ericsson, the Swedish manufacturer of mobile telephones, had been developing for several years a technology that was aimed at freeing computers, phones, and other devices from the wires required to transfer data between them. In 1998 Ericsson assembled a consortium of computer and electronics companies, known as the Bluetooth SIG (Special Interest Group), to bring the technology to the consumer market.
