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. 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 brainchild of providing a low power, low cost wireless interface was first inspired by 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. These companies where Ericsson, IBM, Microsoft, Motorola, Nokia, Intel, Toshiba, and Agere. These companies now promote development and research into the technology of Bluetooth.
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. 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.
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. 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.
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
There have been many different versions of Bluetooth and a lot has changed since version1.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 had many new features, great extra benefits and vast improvement with voice quality, backward compatibility and was in general a better all round 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. 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. Wi-Fi hardware is a lot more expensive Giving Bluetooth an advantage in costs. 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. While other technology may go Bluetooth is here for the long term.
