Aspects of roadside backbone networks

The rapid deployment of wireless networks has radically changed the development methods of applications and solutions. Nevertheless, there are still poorly served areas with network infrastructures, especially the road systems when considering the intelligent transportation systems and on-the-road Internet and entertainment services. While the most known solutions of vehicular communications network concentrated on vehicle-to-vehicle and vehicle-to-roadside networks, road systems-oriented solutions for backbone infrastructures could not be found. Therefore, the demands on backbone infrastructure of roadside from perspective of applications as well as vehicles will be analyzed. Accordingly, a novel concept for a multi-layer wireless backbone based on 802.11 and 802.16 networks is proposed. The developed concept is adaptable for further access technologies.
