In this podcast talk, we will focus on reliability in wireless communications focusing on vehicular use cases and scenarios. It is trivial to say that without reliable message exchange, safe driving is not possible; however, continuously increasing demands for wireless communications in the context of intelligent transportation systems (ITS) cause that reliability is becoming a dominant factor when discussing wireless message delivery. So, what does it mean nowadays to send data reliably, is 99.999% of correctly delivered messages enough to treat vehicular systems as reliable? How would it change in the future? To address these questions, private docent (Priv.-Doz. DI Dr. techn.) Thomas Zemen has kindly agreed to discuss reliability-related issues with us. Thomas is with AIT Austrian Institute of Technology and TU Wien. Thomas, it is a pleasure to welcome you here, and I would like to thank you for accepting our invitation to the talk!
