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. 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. Mobile phones, computers, printers, headsets etc can be connected wirelessly using Bluetooth technology.

The first to try and discover a way to provide low cost, low power interfaces was a company called Ericsson Mobile Communications. Starting in 1994 the probed ways of linking computers and mobile phones 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. 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. Today research and development into the Bluetooth technology is led by these companies.

Bluetooth specifications where developed by Jaap Haartsen and Sven Mattisson two employees of Ericsson Mobile Platforms. Enabling various components from different industries to Connect Bluetooth technology was developed in Scandanavia. 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?

Bluetooth is a wireless communications network which operates on a short-range radio frequency. 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.

To be able to connect to one another devices need to have Bluetooth profiles and need to be compatible with each other. 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 1.1 was able to communicate properly and the great improvements made it truly operable.

Version 1.2 saw vast improvements with many new features and greater benefits, with improved voice quality, backward compatible and a generally better product.

Version2.0 improved even more with features and quality 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.

Other similar technology Such as Wi-Fi is on the market but use different technology although Wi-Fi has a greater operating range. The difference is Bluetooth technology is a lot cheaper as the Wi-Fi hardware is much more expensive. The Bluetooth setup of its services between many devices is simpler, can be automated and security is easier. Local are networks is more for Wi-Fi which is complicated to set up and needs to have all devices configured. 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. Here for the long term Bluetooth Technology will remain a world leader.
