Substitutes a wireless air link for physical connections between electronic devices located in a single area (the piconet). Establishes rapid, ad-hoc connections between one or more devices with required security (point to point, paired, or multipoint). Permits instantaneous, effortless exchange of voice and data between suitably configured devices (the profiles). Accelerates the growth of mobile data connectivity. The Bluetooth Technology Features Flexible network topology Low energy consumption Robust data High quality voice transfer Bluetooth values Trade Marked Freedom Simplicity Reliability Versatility Security What does Bluetooth do for you?
