Drive-thru internet: IEEE 802.1 1b for "automobile" users

This paper reports on measurement results for the use of IEEE 802.11 networks in drive-thru scenarios: we have measured transmission characteristics for sending and receiving high data volumes using UDP and TCP in vehicles moving at different speeds that pass one or more IEEE 802.11 access points at the roadside. We discuss possibilities and limitations for the use of scattered WLAN cells by devices in fast moving vehicles and provide an analysis of the performance that can he expected for the communication in such scenarios. Based on these observations, we discuss implications for higher-layer protocols and applications.
