Who created bluetooth

Bluetooth history

Bluetooth takes its name from a character in history called Harald Bluetooth. He was the king of Denmark born in 910AD and was responsible in 940AD of uniting Denmark and Norway which is where Bluetooth technology gets its conception from. 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. Mobile phones, computers, printers, headsets etc can be connected wirelessly using Bluetooth technology.

The first company to delve into a low cost, low power interface was 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.

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. 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.

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 1.0 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 became a truly operable product and was able to communicate properly due to great improvements.

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 saw more improvements and features 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.

One other technology that is similar is Wi-Fi but it uses a different operating system although the operating range is greater with Wi-Fi. Wi-Fi hardware is a lot more expensive Giving Bluetooth an advantage in costs. 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. Bluetooth is more powerful and has better connections whilst Wi-Fi is better suited for operating larger networks. 

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. 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.

Bluetooth is now the world wide wireless standard and has a bright future. 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. Here for the long term Bluetooth Technology will remain a world leader.
