Bluetooth takes its name from a character in history called Harald Bluetooth. 

    He was born in 910AD and the Bluetooth concept takes his name because in 940AD he had the ability  
	to Unite two warring countries, Denmark and Norway. 
    It was because of the uniting of two countries by Harald Bluetooth that the founders of Bluetooth technology 
	took his name for the principle of uniting two components to work together remotely. 
    Bluetooth technology can unite different technologies like mobile phones, computers, printers, headsets etc.

     Ericsson Mobile Communications had the first idea of finding a low cost, low power interface. 
     In 1994 they started investigating linking mobile phones and computers wirelessly.
    A group of like minded companies joined forces in 1998 to form and association called the Bluetooth Special Interest Group (SIG) in Lund Switzerland.
    This group consisted of companies from different backgrounds including one leader in digital signal processing, 
	two of them were market leaders in the cell phone industry, and the other two were leading laptop manufacturers
    These companies where Ericsson, IBM, Microsoft, Motorola, Nokia, Intel, Toshiba, and Agere. 
    Today research and development into the Bluetooth technology is led by these companies.

    Two employees of Ericsson Mobile Platforms developed the Bluetooth specifications, they where Jaap Haartsen and Sven Mattisson. 
    Enabling various components from different industries to Connect Bluetooth technology was developed in Scandanavia.
    Based on a frequency hopping spread spectrum it is a wireless technology that combines and simplifies multiple forms of communication into a common secure available radio signal.

What exactly is Bluetooth ?

    Bluetooth is a wireless communications network which operates on a short-range radio frequency. 
    Bluetooth technology has the ability to has the ability to be used on any equipment that has its built in features and can exchange information between various device like mobile phones and computers. It is medically safe to use due to its low power use, and the information is carried over a short-range radio bandwidth, known as ISM which is secure, and scientifically sound.

    Devices have to be compatible and anyone wanting to use it will have to have Bluetooth profiles to be able to connect to one another.
    Once the profiles are enabled you should be able to use such things as hands free headsets with mobile phones, and wireless networking and communications which use printers, keyboards and a mouse.

Bluetooth Versions

    Bluetooth has seen many improved qualities with many changes since version 1.0 in 1998 which had many teething problems, like most technology.
    The main problem being a lack of devices being able to communicate.
    Version 1.2 saw all round improvement with vastly superior voice qualities, and many extra benefits.
    Version 1.1 saw great improvements and it became a truly operable product with devices being able to communicate properly.
    Version2.0 saw more improvements and features and now version 3.0 has a Bluetooth master able to communicate with several devices, and at any given time, the slave can become the master.
    The master has the ability to switch between devices very fast.

    Wi-Fi is another wireless operating system and although it has a superior operating range it uses a different technology. 
    The difference is Bluetooth technology is a lot cheaper as the Wi-Fi hardware is much more expensive.
    One big advantage Bluetooth has is its ease of setting it up between many devices, its better security and its automated system.
    Local are networks is more for Wi-Fi which is complicated to set up and needs to have all devices configured.
    Bluetooth is more powerful and has better connections whilst Wi-Fi is better suited for operating larger networks. 

    For operating Bluetooth on a computer it requires Microsoft Windows XP with Service Pack 2 or higher.
    If you run an Apple computer it has been supported by Bluetooth technology since 2002.
    Bluetooth instillation has been carried out on most computers but if not a device called a dongle can be used provided you have windows XP and service pack 2.
    The dongle device allows various devices to communicate with your computer.

    The future of Bluetooth is bright and it has become the world wide wireless standard system. 
     In the future High quality audio and video data will have a much higher quality as Bluetooth improves and the alternative for transporting Bluetooth profile data is MAC PHY. 
    Automatic configuration will be carried out by using Topology Management, and broadcast channelling, which will enable Bluetooth in other devises.
    Manufacturers are now jumping on the bandwagon and using Bluetooth technology and as more components use it the technology will grow.
    While other technology may go Bluetooth is here for the long term.
