Bluetooth Lan Access System

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 development of Bluetooth technology in the internal and the external, explains characteristic and application of Bluetooth, points out the purpose and significance of developing Bluetooth application. Secondly, based on the SIG Bluetooth specification versionl.O, it analyses the whole 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. Finally, by making use of programming in the VC++6.0 and making IP data transfer between two PCs by two hardware platforms(DDP3303) which contain basic core protocol components, we exploit the Bluetooth point to point wireless communication system(that is wireless LAN access point), giving the detailed methods about the design of the hardware and software experimental system.
