Bluetooth was named after a unified Scandinavian king of Denmark and Sweden in the 10th century. It breeds a rather magical prospect: for mobile phones, there is no longer a need to connect to the headset; in personal computers, between the host and the keyboard, display and printer, you can get rid of the confusing connection; on a larger scale, Refrigerators, microwave ovens and other household appliances can be connected to a computer network for intelligent operation.
The invention of Bluetooth technology is the Swedish telecom giant Ericsson. Due to the promising application prospects of this technology, in May 1998, five of the world's top communications/computer companies: Ericsson, Nokia, Toshiba, IBM and Intel, jointly negotiated the establishment of the Bluetooth Common Interest Group (Bluetooth SIG). It is to accelerate its development, promotion and application. After the announcement of this wireless communication technology, it quickly gained the unanimous support of a large number of companies including Motorola, 3Com, Lucent, Compaq, and Siemens. So far, more than 2,000 companies have joined the Bluetooth SIG, including many of the world's most famous ones. Companies in the computer, communications, and consumer electronics industries, and even manufacturers and manufacturers of automobiles and cameras. An open technical specification can receive such extensive attention and support from the industry, which indicates that products based on this Bluetooth technology will have broad application prospects and huge potential market. The Bluetooth Common Interest Group has now been renamed the Bluetooth Promotion Group.
