Bluethooth Wireless Technology

Bluetooth wireless technology is an open, accepted standard for wireless communication. It was developed by Dr. Sven Mattisson and Dr. Jaap Haartsen at Ericsson Mobile Communications in Lund, Sweden. Initially Bluetooth was to be used as an interface between mobile phones and their accessories. It soon became clear that the uses for this new wireless technology were manifold and Ericsson decided to share their technology, offer free licenses to any company that adopted the new technology, and brought together an ideal group to promote this technology. This association, the Bluetooth Special Interest Group, or SIG chose the following as it's Mission Statement: The Bluetooth SIG will support a collaborative environment and drive programs to develop and advance Bluetooth wireless technology in order to exceed personal connectivity expectations and meet the needs of a changing world.

During the formative stage of the Trade Association a code name was needed to name the effort. During a discussion of European history and the future of wireless technology, the name of a 10th century Danish king, Harald Blatand (or Bluetooth, in English) came up. He had been instrumental in uniting warring factions in parts of what is now Norway, Sweden and Denmark, just as the technology is designed to allow collaboration between differing industries such as the computing, mobile phone and automotive markets. The code name stuck.

Bluetooth wireless technology works in an open frequency spectrum at 2.4 to 2.8 gigahertz, the same as wireless networks, telephones and other electronic equipment. It is possible for all types of equipment to operate within the same spectrum without disrupting each other because a frequency consists of several channels which the equipment can "hop" between and, in that way, find channels which are quiet. With the Bluetooth 1.2 standard, electronic equipment can find quiet channels beforehand, communicate...
