Purpose:
     Bluetooth was envisioned by Ericsson, and later created with the help of other companies such as IBM, Intel, Nokia, and Toshiba, who intended to support and promote this new wireless standard. The de facto standard they created allows numerous devices from different companies to interact seamlessly. The name "Bluetooth", given by Ericsson, the primary developer of the technology, comes from the Denmark King, Harald Bluetooth, who united Denmark and Norway around 900AD.
     Ideally, Bluetooth would connect all the electronic data oriented devices in your home into a Personal Area Network (PAN). Your Computer, PDA, mobile phone, stereo, computer peripherals, and others would all be interconnected, and could exchange data cooperatively as needed. For example, your Bluetooth enabled computer receives an email, which it wirelessly forwards to your PDA or mobile phone. In another example, your computer receives a music file from a Bluetooth external modem, and then streams that music file to your Bluetooth home stereo. Some Bluetooth stereos could even play music streamed directly from the Internet, on demand.
     In addition to your own PAN, roaming services can be used while traveling from one area to another. On the road, your Bluetooth MP3 player streams music to your car stereo while your PDA automatically pays for fuel at a Bluetooth enabled gas station. When entering an office or other building, any news or messages can be transmitted to your PDA or mobile phone. The possibilities of interaction are literally endless.
