Research For Embedded System Wireless Communication On Bluetooth And WLAN

Along with the development of compute technic, electron technic and net technic, interlink and wireless communication will be Embedded System developmental direction. Bluetooth is a short distance wireless communication technic. Bluetooth replace the cable between digital equipment, computer and its external equipment, and digital equipment can form a net or interlink by Bluetooth. WLAN can supply Computer communicate by wireless multiplexing, it is possible for communications mobility, individuality and the application of multimedia. Bluetooth and WLAN can been applicable for Embedded System wireless communication because of its superiority.In this thesis, analysed and investigated the character, Core protocol and Profiles of Bluetooth, designed the embedded wireless communication system on Bluetooth, provided the hardware design, the implement of major communication protocol of HCI, L2CAP and SDP, and the interface with Embedded Operation System.In this thesis, analysed and investigated the topological structure and Service of WLAN base 802.11b standard, designed the embedded wireless communication system accord with 802.11b standard, provided the the hardware design and the implement of embedded TCP/IP protocol, and the interface with Embedded Operation System.In this thesis, investigated the interlink mode of Bluetooth and WLAN, designed the project of interlink between the two system, and access Internet, provided the project of Bluetooth access point.
