2. was it called this on behalf of the Bluetooth technolog? • Harald Bluetooth was king of Denmark around the turn of the last millennium. He managed to unite Denmark and part of Norway into a single kingdom • then introduced Christianity into Denmark. • He left a large monument, the Jelling rune stone, in memory of his parents. He was killed in 986 during a battle with his son , SvendForkbeard . • Choosing this name for the standard indicates how important companies from the Baltic region (nations including Denmark, Sweden, Norway and Finland) are to the communications industry

3. What Is Bluetooth? Bluetooth is a proprietary openwireless technology standard for exchanging data over short distances (using short wavelength radio transmissions) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994,[1] it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Today Bluetooth is managed by the Bluetooth Special Interest Group.

4. 1- Take a look around Look around you at the moment, you have your keyboard connected to the computer, as well as a printer, mouse, monitor and so on. What (literally) joins all of these together?, they are connected by cables. Cables have become the bane of many offices, homes etc. Most of us have experienced the 'joys' of trying to figure out what cable goes where, and getting tangled up in the details. Bluetooth essentially aims to fix this, it is a cable-replacement technology.

5. 2- How? • Conceived initially by Ericsson, before being adopted by a myriad of other companies, Bluetooth is a standard for a small , cheap radio chip to be plugged into computers, printers, mobile phones, etc . • A Bluetooth chip is designed to replace cables by taking the information normally carried by the cable, and transmitting it at a special frequency to a receiver Bluetooth chip, which will then give • the information received to the computer, phone WHatever.

6. 3-  How about ? That was the original idea, but the originators of the original idea soon realised that a lot more was possible. If you can transmit information between a computer and a printer, why not transmit data from a mobile phone to a printer, or even a printer to a printer?. The projected low cost of a Bluetooth chip (~$5), and its low power consumption, means you could literally place one anywhere

7. 4 - Ideas, ideas... With this viewpoint interest in Bluetooth is soaring, lots of ideas are constantly emerging, some practical and feasible e.g.: Bluetooth chips in freight containers to identify cargo when a lorry drives into a storage depot, or a headset that communicates with a mobile phone in your pocket, or even in the other room, other ideas not so feasible : Refrigerator communicating with your Bluetooth-enabled computer, informing it that food supply is low, and to inform the retailer over the internet.

8. A typical Bluetooth mobile phoneheadset. • Wireless control of and communication between a mobile phone and a handsfreeheadset. This was one of the earliest applications to become popular. • Wireless networking between PCs in a confined space and where little bandwidth is required. • Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer.

9. Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX. • Replacement of traditional wired serial communications in test equipment, GPS receivers, medical equipment, bar code scanners, and traffic control devices. • For controls where infrared was traditionally used. • For low bandwidth applications where higher USB bandwidth is not required and cable-free connection desired.
