This paper introduces concept and merits and demerits of wireless local area network (WLAN), analyzes the IEEE 802.11 series standards of WLAN. Based on simulation platform OPNET, the network model, node model and process model of distributional WLAN are constructed. The network performances of WLAN under 802.11 series standards are studied. The results indicate that setting different network parameters...
