Bluetooth Information

The Bluetooth wireless technology allows users to make effortless, wireless and instant connections between various communication devices, such as mobile phones and desktop and notebook computers. Since it uses radio transmission, transfer of both voice and data is in real-time. The sophisticated mode of transmission adopted in the Bluetooth specification ensures protection from interference and security of data.

The Bluetooth radio is built into a small microchip and operates in a globally available frequency band ensuring communication compatibility worldwide. The Bluetooth specification has two power levels defined; a lower power level that covers the shorter personal area 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.

The Bluetooth wireless technology supports both point-to-point and point-to-multipoint connections. With the current specification, up to seven 'slave' devices can be set to communicate with a 'master' radio in one device. Several of these 'piconets' can be established and linked together in ad hoc 'scatternets' to allow communication among continually flexible configurations. All devices in the same piconet have priority synchronization, but other devices can be set to enter at any time. The topology can best be described as a flexible, multiple piconet structure.
