Abstract: With the rapid development of the WALN, more and more people wish to use it to connect to the Internet and it has become a very good accessible mode with its super advantages. Now the WLAN MAC layer protocol is a hotspot in the WLAN research．This paper researches the IEEE 802.11 DCF protocol and proposes a scheme to make a bridge between the Ethernet and WLAN. It expatiates the function of the main module unit and makes a more particular introduction to the main idea and workflow of the implementation of the IEEE 802.11 DCF protocol with FPGA.
