Mobile communication based on wireless local area network (WLAN) technology have potential to support automated guided vehicle and in the same time to obtain Internet connectivity for users in-motion. Wireless access for the vehicular environment based on IEEE802.11p technology provides the required principally standardization for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) solution, and supports raw data rate up to 27 Mbps. While devices based on IEEE802.11n technology for mobile users can provide data rate up to 600Mbps. In this article is presented an experimental study of IEEE802.11n in legacy mode settings compare to IEEE802.11g standard using off-the-shelf equipments in vehicle to infrastructure scenario. In particular, there is shown the performance of TCP transfer between a high mobile user and stationer WLAN base stations.
