Bluetoothâ ¢ is a promising wireless technology designed for short-range ad-hoc connections, and it has many potentially useful applications. One such use is the transfer of data between two fast-moving vehicles such as automobiles. In this paper we explore the suitability of Bluetooth to make connections in highly mobile environments. In particular, we have developed a hardware testbed to make an empirical analysis of the time it takes to establish Bluetooth connections and the impact this will have on any potential data transfer. We also propose changes in the Bluetooth standard that may offer faster connection setup times.
