IEEE802.11A STANDARD PERFORMANCE IN MOBILE ENVIRONMENT

In this paper we reflect evaluation of Wireless Local Area Network (WLAN) standard in a vehicular environment. WLAN based on the IEEE802.11a standard in wireless user community is widespread and well known to ensure wireless communication. This standard can be used indoor environment for stationary and slowly move users. Despite this fact we analysed this wireless communication standard to understand basic performance and suitability for Intelligent Transportation Systems (ITS) providing a ubiquitous mobile INTERNET access. A wireless vehicular communication tests in real scenario usually require a large number of vehicles and testers for proper results. To derive an experimental result we used simulation/emulation tool such as National Chiao Tung University- network simulator (NCTUns).
