How Does Bluetooth Work?

The functioning of Bluetooth is very technical in nature, but to put it in very simple words, Bluetooth uses frequency hopping in timeslots. Apart from frequency-hopping, Bluetooth uses a fast acknowledgement to ensure a better communication link, and it avoids the interference caused by signals by simply moving on from one frequency to another. It usually hops faster and uses shorter packages to avoid the impact of disturbances.

Bluetooth works at two levels of power, a lower level of power that can cover a smaller area, such as that of a room, and a higher level of power, which covers a larger area, such as within a home. Each microchip has a built-in set of safety controls and identity codes that can be preset and used only by the owner of the Bluetooth-enabled gadget. Bluetooth communication is done through a master unit and there is no direct communication between slave units.

Bluetooth supports either asynchronous data channels, upto three synchronous and simultaneous voice channels or one channel which simultaneously supports asynchronous data and synchronous voice.
