Bluetooth History
Bluetooth Technology was named after the King of Denmark, who was born in 910 AD, and by 940 AD, he was responsible for uniting Denmark and Norway, which is where Bluetooth technology was first invented. Because Harald Bluetooth made history by uniting the two countries, Bluetooth technology is suppose to unit different technologies between mobile phones and computers.
Starting in 1994 a cell phone company named Ericsson Mobile Communications began an investigation between computers and mobile phones to find a low cost and low power interface. In 1998 a Special Interest Group in Lund, Sweden, was formed which included Intel, Ericsson, IBM, Toshiba, and Nokia. One of them was a leader in digital signal processing, two of them were market leaders in the cell phone industry, and the other two were leading laptop manufacturers. Jaap Haartsen and Sven Mattisson, who were employed by Ericsson Mobile Platforms, developed the specification of Bluetooth, which was based on a frequency hopping spread spectrum.
Prior to 2002 the SIG had made the assessment that by 2002 Bluetooth technology would be installed in notebooks, PC’s, and desktop computers, and it would be installed in over 100 million cell phones, and millions of other communication devises.
Bluetooth is a wireless communications network that operates on a short-range radio frequency. It provides a way for exchanging information when it is connected to any computer or accessory and mobile phone or any apparatus that has the Bluetooth technology as a built in feature. This information is carried over a secure Industrial, Scientific, and Medical short-range radio bandwidth, known as ISM.
For anyone to be able to use Bluetooth, their devise will have to be compatible with some Bluetooth profiles, such as cell phones and hands free headset, wireless networking and communications, which used a keyboard, mouse and printer.
Bluetooth has come from 1.0, which had many problems that needed to be straightened out to 3.0, a master Bluetooth is able to communicate with seven devices, and at any given time, the slave can become the master. The master hast the ability to switch between devices very fast.
There is a major difference between Bluetooth and Wi-Fi even though they use the same frequency range, but different techniques. Wi-Fi has a much greater distance, but the hardware to operate it is much more expensive. Bluetooth simplifies the setup of its services between many types of devices, which makes security easier and can be automated. Wi-Fi has t be configured to set up share resources and transmit files more for Ethernet networking. Bluetooth has more power and will have a stronger connection, whereas, Wi-Fi setup is more suited for operating full-scale networks.
The computer requirements for Bluetooth require Microsoft Windows XP with Service Pack 2 or higher, and on the Apple has supported Bluetooth since 2002. If your computer does not already have Bluetooth but has XP, SP2, you can purchase a Bluetooth adapter called a Dongle, this will allow multiple devices to communicate with a computer.
Bluetooth has become very popular since its beginning and the future of Bluetooth technology will see many improvements such as audio and video data at a higher quality, an alternate MAC PHY, which enables transporting of Bluetooth profile data; Topology Management, which enables some automatic configuration, and Broadcast channelling, which will enable Bluetooth in other devises.
