Executive Summary

A particular class of vehicular networks is the one that includes off-the-shelf end-user equipments (e.g., laptops and PDAs) running from the interior of vehicles, namely in-car nodes. They are subject to limited communication conditions when compared with nodes specifically designed to this context. Existing works either consider antennas installed on top of the vehicle roof or nodes that operate in infrastructure mode. In this paper, the authors investigate through real experiments the characteristics of links formed by in-car nodes running off-the-shelf wireless technologies such as IEEE 802.11(a/g) in ad hoc mode.
