Bluetooth technology refers to an open protocol for exchanging data between different devices using wireless communication over short distances using short wave length radio waves. The word bluetooth is derived from the danish word Blataand, which refers to a tenth century King who united many tribes of Norway and Denmark into a single kingdom. The word refers to the ability of this system to integrate many different types of devices.Bluetooth is also known as IEEE802.15 Standards
That applications of Blue toot include among others the following.
- Mobile phones and hands free head sets.
- Networking between PC located within short distances.
- Wireless communication between PC and its peripherals such as mouse, keyboard and printer.
- Wireless consoles of computer games.
- Wireless transmission of health sensor data.
- Dial up access of PC to Internet.

Blue-tooth is a radio technology that makes it possible for mobile phones, cellphones, computers and other electronic devices to be linked over short distances, without needing to be connected by wires.
Blue-tooth technology is a short-range wireless radio technology that allows electronic devices to connect to one another. Generally, Blue-tooth has a range of up to 30 ft. or greater, depending on the Blue-tooth core.
Blue-tooth wireless technology makes connections just like cables connect a computer to a keyboard, mouse, or printer, or how a wire connects an MP3 player to headphones.
Blue-tooth technology was first developed by Ericsson and then formalized by a group of electronics manufacturers (Ericsson, IBM, Intel, Nokia, and Toshiba) who joined forces to form a private trade association known as the Blue-tooth Special Interest Group (SIG).
