A Hybrid Solution for Vehicular Communications

Free registration required

Executive Summary

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 WLAN based ad-hoc networks of vehicles and roadside infrastructure. UMTS is a state-of-the-art technology for mobile communication and offers a cellular infrastructure based solution. This paper presents a comparative study of these two technologies and reveals that they are complementary to each other in supporting vehicular applications. The authors also propose a hybrid solution combining both WAVE and UMTS technologies to optimize the performance of the vehicular communication system, to increase the market penetration rate and to reduce the deployment costs.
