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. Bluetooth technology can unite different technologies like mobile phones, computers, printers, headsets etc.
The brainchild of providing a low power, low cost wireless interface was first inspired by Ericsson Mobile Communications. 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.
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.
Bluetooth definition?
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. 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. 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.
Versions of Bluetooth
Improved features and more benefits have seen Bluetooth improve and change since version 1.Introduced in 1998 and like most other new technologies had many teething problems. The lack of devices able to communicate with each other was one of the problems.
Version 1.1 saw great improvements and it became a truly operable product with devices being able to communicate properly.
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 is able to communicate with several devices using a Bluetooth master device in which the slave can become the master at any given time. Master devices use there ability and can swiftly switch from one device to another.
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. 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.
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. 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. While other technology may go Bluetooth is here for the long term.
