INTRODUCTION Bluetooth is a wireless LAN technology designed to connect devices of different functions such as telephones, notebooks, computers (desktop and laptop), cameras, printers, and coffee makers. A Bluetooth LAN is an ad hoc network, which means that the network is formed spontaneously but sometimes it called gadgets and make a network called a piconet. The cable-free, or wireless, technology was initially conceived by Ericson in 1994, when the company began a study to investigate the feasibility of a low-power, low-cost radio interface between mobile phones and their accessories. The company’s goal was to eliminate the need for cables. Bluetooth technology was intended to hasten the convergence of voice and data to handheld devices, such as cellular telephones and portable computers. Through the efforts of its developers and the members of the Bluetooth Special Interest Group (SIG), it is now emerging with features and applications that not only remain true to its original intent, but also provide for broader uses of its technology. The word Bluetooth is taken from the 10th century Danish King Harald Bluetooth. King Bluetooth had been influential in uniting Scandinavian Europe during an era when the region was torn apart by wars and feuding clans. Nowadays, Bluetooth technology is the implementation of a protocol defined by the IEEE 802.15 standard. The standard defines a wireless personal-area network (PAN) operable in an area the size of a room or a hall. APPLICATIONS 1 Bluetooth Components 1.1.

They can also restrict the things that different Bluetooth can do with other devices using what's called service-level security. Conclusion As you can see, the Bluetooth specification is definitely real and is being widely adopted by industry leaders. The possibilities for new applications is very exciting with this versatile technology. Hopefully this article has provided a basic understanding of the Bluetooth architecture so that you can delve into the 1082 page Bluetooth specification or some of our future, more detailed articles on the Wireless Developer Network.
