Abstract

The Bluetooth specification was developed in 1994 by Jaap Haartsen and Sven Mattisson, who were working for Ericsson Mobile Platforms in Lund, Sweden. The specification is based on frequency-hopping spread spectrum technology. The specifications were formalized by the Bluetooth Special Interest Group (SIG). The SIG was formally announced on May 20, 1998. Today it has a membership of over 7000 companies worldwide. It was established by Ericsson, IBM, Intel, Toshiba, and Nokia, and later joined by many other companies. Wireless communication is currently becoming popular and evolving to support communication needs for wide range of applications. It gives opportunity to wireless data transfer technologies such as Infrared, Home radio frequency (RF), Wi-Fi and Bluetooth to be improved for future benefit. With the advancement of radio frequency (RF) and semiconductor technologies, researchers are now concentrating effort in developing Pico-networks where electronic devices can communicate within 100 meters without requiring any fixed infrastructure. The best & cost efficient future is Bluetooth, a technology named after a 10th century king who brought warring Viking tribes under a common rule. The choice of operating in the license-exempt band that is ISM (Industrial Scientific Medical) band which ranges from 2.4 GHz to 2.4835 GHz enable the goals of global applicability, low power and high aggregate capacity to be meet. To be more specific, this project demonstrates the development of the household and office devices that can be controlled using wireless Bluetooth technology, which is suitable for a wireless home or office environments. This system can be adapted to the needs of the customer, for an example this system used as long as the device is able to read the Visual Basic Program.
