Wireless access infrastructure, such as Wi-Fi access points and cellular base stations, plays a vital role in offering pervasive Internet services to vehicles. However, the deployment costs of different access infrastructure are highly variable. In this chapter, we analyze the downlink capacity of vehicles and investigate the capacity-cost tradeoffs for the network in which access infrastructure is deployed to provide a downlink data pipe to all vehicles. Three alternatives of wireless access infrastructure are considered, i.e., cellular base stations (BSs), wireless mesh backbones (WMBs), and roadside access points (RAPs). We first derive a lower bound of downlink capacity for each type of access infrastructure. We then present a case study based on a ideal city grid of 400 km2 with 0.4 million vehicles, in which we examine the capacity-cost tradeoffs for different deployment solutions in terms of both capital expenditures (CAPEX) and operational expenditures (OPEX). Rich implications from the results provide fundamental guidance on the choice of cost-effective wireless access infrastructure for the emerging vehicular networking.
