Overview#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).
Bluetooth can connect up to seven devices, overcoming problems that older technologies had when attempting to connect to each other.clarify
The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth Special Interest Group (SIG) oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet Bluetooth Special Interest Group standards to market it as a Bluetooth device. A network of patents apply to the technology, which are licensed to individual qualifying devices.
