BlueTooth is a wireless protocol data communication protocol. Like all wireless protocols BlueTooth is designed to replace wires, only in this case we are talking short, low speed wires. Bluetooth can communicate in a 10M range with a maximum aggregate throughput of 1Mbit/s. This is enough to use between handheld devices such as mobile phones and PDAs, but not enough to use for real-time streaming video. Bluetooth has dedicated 64kbit/s voice channels and is well suited to replacing wires for cellphone headsets and the like.

Bluetooth uses a master/slave arrangement called a Piconet, which allows for 7 active slaves per master. The bandwidth (from the 2.4GHz ISM range) is allocated using TimeDivisionMultiplexing (TDM).
