Bluetooth is a low bandwidth wireless networking technology designed primarily to replace cables for communication between personal computing/communication devices. It is intended to be used for both voice and data communications.

Bluetooth operates at 2.4 GHz and is capable of transmitting voice and data. The average effective range of many Bluetooth devices is 32 feet (10 meters). The voice channels support 64Kb/s. An asymmetric data rate (one way) of 721Kb/s (while permitting 57.6Kb/s in the return direction); and symmetric rate of 432.6Kb/s is possible according to Bluetooth spec.
