 Bluetooth
Bluetooth is a standard developed by a group of electronics manufacturers that allows any sort of electronic equipment -- from computers and cell phones to keyboards and headphones -- to make its own connections, without wires, cables or any direct action from a user.
With many different Bluetooth devices in a room, you might think they'd interfere with one another, but it's unlikely that several devices will be on the same frequency at the same time, because Bluetooth uses a technique called spread-spectrum frequency hopping.
Bluetooth systems create a personal-area network (PAN), or piconet, that may fill a room or may encompass no more distance than that between the cell phone on a belt-clip and the headset on your head.

 Bluetooth Security Review, Part 1
The idea behind Bluetooth technology was born in 1994, when a team of researchers at Ericsson Mobile Communications, led by Dr. Jaap Haartsen and Dr. Sven Mattisson, initiated a feasibility study of universal short-range, low-power wireless connectivity as a way of eliminating cables between mobile phones and computers, headsets and other devices.
The Bluetooth address itself is a unique 48bit device identifier, where the first 3 bytes of the address are assigned to a specific manufacturer by the IEEE (www.ieee.org/), and the last 3 bytes are freely allocated by the manufacturer.
Bluetooth addresses can also be extracted during Bluetooth communication, as the address itself is not encrypted even if user chooses to encrypt the rest of the communication.
