History of Bluetooth
Bluetooth history
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. The founders of Bluetooth took the name of Harald Bluetooth because of the way he united two countries together and in the same way Bluetooth unites two dissimilar components. The use of Bluetooth technology has the ability of linking the different technologies like , computers, mobile phones, printers, headsets etc.
The first company to delve into a low cost, low power interface was Ericsson Mobile Communications. They started looking into ways of linking cell phones and computers without wires in 1994. In 1998, Lund Switzerland saw the formation of like minded companies who united into an association called the Bluetooth Special Interest Group (SIG). Coming from different backgrounds the group included market leaders in laptop manufacturing, the cell phone industry and digital signal processing. Included in this group where Motorola, Nokia, Intel, Toshiba, Agere, Ericsson, IBM, and Microsoft. These companies now promote development and research into the technology of Bluetooth.
Ericsson Mobile Platforms had two employees Jaap Haartsen and Sven Mattisson which developed the Bluetooth specifications. Developed in Scandinavia Bluetooth technology is able to unite different components from different industries such as computing, cell phones and automotive markets. This wireless technology is based on a frequency hopping spread spectrum providing a secure radio signal that combines and simplifies multiple forms of communication.
The Bluetooth Special Interest Group made a firm commitment to have Bluetooth technology installed in various devices and by 2002 Bluetooth technology was installed in PC’s, notebooks, desktop computers and over 100 million mobile phones had the technology as well as millions of other communications devices.
What exactly is Bluetooth?
Operating on a short-range radio frequency it is a wireless communications network. When connected to various devices such as mobile phones and computers it provides a way of exchanging information as well and the Bluetooth technology can be used on any other apparatus that is provided with it’s built in features. Due to its very low power it is medically safe to use, the information it carries using short wave radio and narrow bandwidth know as ISM is scientifically sound and very secure.
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. You can use things like mobile phones, hands free headsets, printers with wireless network communications, keyboards and a mouse, provided the profiles have been enabled.
Bluetooth Versions
Bluetooth has seen many improved qualities with many changes since version 1.Introduced in 1998 and like most other new technologies had many teething problems. The main problem being a lack of devices being able to communicate.
Version 1.1 was able to communicate properly and the great improvements made it truly operable.
Version 1.2 saw all round improvement with vastly superior voice qualities, and many extra benefits.
Version2.0 improved even more with features and quality and now version 3.0 is able to communicate with several devices using a Bluetooth master device in which the slave can become the master at any given time. 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. However Bluetooth is cheaper to run than the more expensive Wi-Fi hardware. One big advantage Bluetooth has is its ease of setting it up between many devices, its better security and its automated system. Wi-Fi is more complicated to set up and needs to have devices configured to set up shared resources which are more for Ethernet networking. Wi-Fi is better suited for operating larger networks while Bluetooth has more power and better connections.
Microsoft Windows XP with Service Pack 2 or higher is required to operate Bluetooth on a computer. If you run an Apple computer it has been supported by Bluetooth technology since 2002. Nearly all computers now have Bluetooth installed but if not then if your computer has Windows XP with Service pack 2 then a device called a dongle can be purchased. 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. The chain reaction is already in progress and as more components use Bluetooth technology, manufacturers of electronics will jump on the band wagon and become increasingly eager to make their products compatible. Bluetooth technology is here to stay.
