基於Linux之IEEE 802.16e無線路由器開發

Most of wireless routers on market is adopted IEEE 802.11a/b/g/n (Wi-Fi) communication protocols. Due to its short transmission distance as well as bandwidth is limited, it is generally be used in interior spaces. Such as families or small business. For same reason, the maintenance has certain difficulty to do. IEEE 802.11a/b/g/n (Wi-Fi) communication protocols has been in development since 1999 for nearly a decade, the specific implantation issues are relatively stable gradually and turn into a new choice of urban wireless broadband network. Outstanding transmission speed and distance are two features that WiMax is better than WiFi . Based on these advantages, it can be used on better current wireless routers and make them as a long distance and high speed wireless routers. This allows router application become more flexible. The essence of this paper is to apply Linux-based router operating system software BrazilFW on x86 hardware platform and linked by Intel WiMAX 6250 wireless card. Compiled and installed network card drivers and related needs operation kit tools. The implementation of WiMAX wireless router would assist maintainers save wiring costs, installation locations can be longer and more flexible. Router maintenance operation becomes more convenient by means of remote login. Flexibility, reliability, and stability are increased relative to the existing Wi-Fi wireless routers. By using open-source software tool and PC platform, this paper is to materialize a WiMAX wireless router.
