Communication capabilities in future vehicles and a road-side infrastructure, deploying wireless LAN IEEE 802.11 technology, are expected to provide internet access for drivers and passengers. This paper analyzes two approaches for internet access with respect to its technical deployability in vehicular scenarios: With increasing proliferation of WIFI hot spots, access points at public places can be reused in scenarios with low mobility. Alternatively, road-side units mainly dedicated to road safety, can be enhanced to provide internet connectivity as an additional service. Judging the merits of public hot spots and dedicated road-side units, an integrated solution is proposed and technical issues for their deployment are discussed. Experiments in a real-world environment demonstrate the feasibility ofvehicular internet access. For the covering abstract see E134653.
