Performance evaluation of IEEE 802.11n devices for vehicular networks

The high-speed WLAN is standardized by the IEEE 802.11 task group n. For wireless access in vehicular environments, it is standardized as IEEE 802.11p which is based on 802.11n. Devices for wireless communication based on 802.11n draft are widely spreading in the world market now, but there is no report available which discusses the performance of such 802.11n devices. In this poster, we introduce a basic performance evaluation of IEEE 802.11 devices. We show experimental results using 802.11n draft 2.0 devices which are available on the market. In particular, we tested the throughput performance and the coverage range of IEEE 802.11n devices in outdoor environments during a car to car communication scenario. The experimental results show the limits of using IEEE 802.11n devices in vehicular networks.
