Bluetooth technology history

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. The use of Bluetooth technology has the ability of linking the different technologies like , computers, mobile phones, printers, headsets etc.

The brainchild of providing a low power, low cost wireless interface was first inspired by Ericsson Mobile Communications. First explorations took place in 1994 to wirelessly connect computers to mobile phones. In 1998, Lund Switzerland saw the formation of like minded companies who united into an association called the Bluetooth Special Interest Group (SIG). 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. 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.

Ericsson Mobile Platforms had two employees Jaap Haartsen and Sven Mattisson which developed the Bluetooth specifications. 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.

Bluetooth definition?

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. Using a short wave narrow bandwidth it uses low power and therefore is medically safe to use, it is also a scientifically sound system with excellent security.

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.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 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 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. The difference is Bluetooth technology is a lot cheaper as the Wi-Fi hardware is much more expensive. 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.

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.

what exactly do you need to get the internet?

dongle, phone line and cable? hardware and software. do suppliers supply all that you need?
its for a friend

Well, the main basics are:

An internet connection that is provided. It usually comes in a few forms

A modem that you plug a cable into, it can be a Coaxial cable or a telephone ADSL cable.
You then plug your computer into this modem. Or, the modem is connected to a wireless router, the router then 'splits' the connection so multiple PC's can use it. Or the modem itself could be wireless already so it eliminates the need for a router.

There is a wireless modem that is small in size, (often called a Dongle, if it looks like a USB stick or a card...if it looks like a card) and plugs straight into your computer via USB or PCI card. It works by tapping into cell phone signals, (not Wifi signals). Mobile phones use this kind of internet as well.

Software: Provided by your company. If you use Wireless internet, you will certainly have to use the software to be able to use the dongle/card. The software also gives you facilities to manage your internet account, check bills and usage etc.

Hardware:
Cables. Once again, usually provided but the most common cable you'll see is a CAT5 cable which typically links your PC to a modem.
