5G challenges for connected, cooperative and automated transport systems

The Wifi-based V2X Communication technology ITS-G5 (a.k.a DSRC in the US) is the currently only market-ready solution to provide safety-critical V2X communications for future C-ITS applications, such as road hazard warning, lane-change warning or intersection-collision warning. Yet, future Connected Cooperative Automated Transport Systems (CATS) are expected to require ultra-reliable and low latency connectivity that neither the current WiFi technology nor even the new Cellular V2X technology can provide. This talk will first provide a rapid overview of the benefit of these future CATS  as well as their expected communication requirements , then briefly review the state and capabilities of the current Wifi and Cellular V2X technologies, and finally describe the 5G challenges and roadmap  to meet the communication, networking and services required by these future Connected Cooperative Automated Transport Systems.
