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.

Key words: WLAN, DCF, MAC layer, FPGA

摘要： 针对无线局域网无可比拟的接入优点，研究了IEEE 802.11 MAC层DCF协议的主要功能，提出了一种实用的、可扩展的DCF协议的设计方案，为进一步研究无线局域网的接入协议提供保障，实现了以太网与无线局域网的互联互通。该文阐述了设计方案主要模块单元的功能，介绍了FPGA内部设计的主要思想和数据流程。
