Wireless Access in Vehicular Environments (WAVE) and Universal Mobile Telecommunication System (UMTS) are two technologies that can be used for vehicular communication. WAVE realizes Car-to-X (C2X) communication with WLANbased ad-hoc networks of vehicles and roadside infrastructure. UMTS is a state-of-the art technology for mobile communication and offers a cellularinfrastructure based solution. This paper presents a comparative study ofthese two technologies and reveals that they are complementary to each other in supporting vehicular applications. We also propose a hybrid solution combining both WAVE and UMTS technologies to optimize the performance ofthe vehicular communication system, to increase the market penetration rate and to reduce the deployment costs.
