In 1921, staff in Vahrenwald ensured secure communication within the Continental buildings by using telegraph devices and pneumatic post tubes. Today, Continental is connecting cars with the aid of V2X technology (vehicle-to-everything technology) via a 4G and 5G network to ensure greater safety and efficiency on the roads. The real-time transmission of changes in traffic flows can prevent accidents, for instance. Furthermore, coordinated vehicle processes help to reduce fuel consumption and therefore conserve resources.
