The Best Bluetooth

Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices through short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal field networks (PANs). It was originally conceived as a wireless way to RS-232 data cables.

Bluetooth is handled by the Bluetooth singular Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and buyer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer holds the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and guards the trademarks.[3] A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device.[4] A network of patents apply to the technology, which are accredited to individual qualifying devices. As of 2009, Bluetooth integrated circuit chips ship close to 920 mlln. units annually
