Bluetooth is a global open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.
Bluetooth wireless technology was developed by Jaap Haartsen Mattisson Svenis in 1994 and is the global short-range wireless standard enabling connectivity for a broad range of electronic devices using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz.
Features include:
- small-form factor radio
- low power
- low cost
- built-in security
- robustness
- ease-of-use
- ad hoc networking abilities.
Manufacturers and consumers can choose to activate one or all of these features in Bluetooth enabled devices, depending on device functionality.
