Origin of the name "Bluetooth" "Bluetooth" was named after a Viking who was a Danish King-Harald Blatand. Blatand was loosely translated into “Bluetooth” But what could an ancient king name got to do with the wireless transferring technology? They may not have connection between each other, but it comes from an interesting origin: Harald Blatand is reported to have united Demark and Norway, and hence so as the wireless technology uniting people. Organization of Bluetooth In May of 1998, Intel、Ericsson、Nokia、IBM and Toshiba were formed as a Special Interest Group, named SIG, its goal is to set up a short range radio frequency wireless technology. By June of 1999, members of SIG had been increased to 751 members, which includes Compaq、Dell、Motorola、3Com、HP、Lucent、and Samsung, and they have all come to a consensus of royalty free standard in order to lower the technical cost for making it being widely used.

Introduction Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 25,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1 , but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must make a device meet Bluetooth SIG standards to market it as a Bluetooth device. A network of patents apply to the t...
