The innovative Cooperative Intelligent Transport Systems (C-ITS) of T.net allow the interaction between vehicles, the road infrastructure and the actors involved in the use of the infrastructure. With T.net’s C-ITS solution, V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure) communication is overcome, to achieve V2X (vehicle-to-everything) cooperation, with obvious advantages of efficiency, safety and for the environment. The use of both 802.11p protocol and LTE / 4G / 5G networks makes it possible to create projects capable of supporting technological evolution without compromise.
