Gateway can realize the function of conversion between 802.11b/g/n high-speed wireless LAN, Ethernet WAN and RS serial port communication based on the embedded Linux operating system OpenWrt and embedded microprocessor RT5350. Background data base is established using html and php languages and the administrator can have an easier control on the bulletin board information and set the parameters of gateway. This bulletin board gateway system has been established and tested at the XUPT campus.
