The Research On Bluetooth Wireless Communication Technology

With the unprecedented development and mutually blended of the internet and mobile communication technology, much new technology and many new criterions appeared. Bluetooth is one kind of these short distance wireless communication criterions. It allows you establish links between mobile equipments by wireless interface, so it has wide application foreground.Firstly the paper makes a survey of the development of Bluetooth technology in the internal and the external, explains charactoristic and application of Bluetooth, points out the purpose and significance of developing Bluetooth application. Secondly, based on the SIG Bluetooth specification version1.1, it analyses the wholesome framework of specification of Bluetooth technology and the contents of the Bluetooth protocol stack. Thirdly, it discusses the wireless layer, baseband layer and HCI in detail. On the basis of above knowledge, we comprehend the relations among the different Bluetooth protocol layers and the principle of data transferring between two Bluetooth protocol layers. Finally, by making use of programming in the VC++ 6.0 and making connection between two PCs by the Ericsson Bluetooth module ROK101 008, we exploit the Bluetooth point to point wireless communication system, giving the detailed methods about the design of the hardware and sofeware experimental system. Finally, we analyse the results of the experiment, presenting a discussion as well as the future of Bluetooth technology.
