Bluetooth wireless technology is aimed at allowing users to make effortless, fast connections between various devices. The sophisticated mode of transmission adopted in the Bluetooth Specification ensures protection from interference and seeks to ensure security of data. The radio with Bluetooth wireless technology is built into a small microchip and operates in a globally available frequency band intended to ensure communication compatibility worldwide. The Specification has two power levels defined: a lower power level that covers the shorter personal proximity range within a room, and a higher power level that can cover a medium range, such as within a home. Software controls and identity coding built into each microchip ensure that only those units preset by their owners can communicate.
