C-V2X-Technologien in vernetzten automatisierten Fahrzeugen ermöglichen den Informationsaustausch zwischen Fahrzeugen, wobei die Fahrzeuge sowohl mit dem Netz als auch miteinander über äußerst zuverlässige und reaktionsschnelle, sichere und hochleistungsfähige Verbindungen kommunizieren. Wenn diese Form der Konnektivität möglich wird, fördert dies die Entstehung disruptiver neuer Anwendungen und Unternehmensdienstleistungen, die zu einer vorausschauenden Fahrunterstützung, zusätzlicher Verkehrssicherheit und schließlich der umfassenden Verbreitung vollautomatisierter Fahrzeuge führen. Auf dem Weg zum vollautomatisierten Fahren bestehen erhebliche Herausforderungen für das Netz und die Fahrzeuge, wenn es darum geht, Dienste für Fahrzeuge auf unterschiedlichen Ebenen der Automatisierung bereitzustellen.
