The future of vehicle networking is hybrid
The integration of drones, high-altitude platforms (HAPs) and satellites into mobile networks creates a hybrid network in which the mobile infrastructure on the ground works seamlessly with network components in the air and in space. This 3D connectivity gives vehicles a seamless and ubiquitous connection via 5G and, in future, 6G and opens up completely new opportunities for network operators and vehicle manufacturers to develop vehicle-to-everything (V2X) connectivity services. V2X connects cars with each other, but also with pedestrians, the traffic infrastructure and the internet.
The convergence of terrestrial networks (TN) and non-terrestrial networks (NTN) eliminates the lack of mobile coverage in certain areas. At the same time, however, complexity is exploding. In hybrid TN/NTN networks for V2X communication, it is not only the vehicles that are in motion, but also the base stations on satellites, drones and HAPs. The result: more dynamics, more handovers, more interference. What network performance can be expected and whether planned or existing networks are reliable and powerful enough to guarantee the functioning of safety-relevant automotive applications can only be clarified with the help of realistic simulations. In order to simulate processes and structures in highly dynamic and complex 3D networks, we use our own TN/NTN system level simulator.
