Communication Technologies for Mobility Networks

Connected Mobility – Vehicle Communication

In the field of connected mobility, research and develop at Fraunhofer IIS revolves around leading-edge technologies for the intelligent networking of vehicles, using both car-to-car and car-to-environment scenarios. Thus, we are working to enable the implementation of intelligent traffic management systems and autonomous driving. The focus is on efficient mobility: less traffic congestion, increased safety and optimal information provisioning, anywhere and at any time, and thus a higher degree of comfort and streamlined mobility for all traffic participants.

The required underlying technology is based on transmission technologies that provide full-coverage, reliable broadband provisioning for the mobile user, plus intelligent antennas and broadband automotive networks. Our research activities are focused on improving communication between the various data sources and processing platforms. The following key issues are being addressed:

  • Hybrid network technologies: merging of different wireless technologies and standards to what the user perceives as a transparent communication channel
  • Broadband provisioning for the mobile user: enhancement of communication standards and technologies in order to address the growing demand for mobile data
  • Broadband automotive E/E system concepts: high-speed connectivity for fast and efficient distribution of data in the vehicle
  • New services and applications: development of initial prototypes for testing and optimization of the new technologies

The new technologies will enable the automobile industry, infrastructure operators and service/application providers to design vehicles and traffic concepts for the future.

Intelligent connectivity

The vehicles of the future will communicate continuously with the environment and react independently when danger situations arise. The key to this development is the intelligent networking of vehicles, which are permanently connected to the Internet, with other vehicles, the surrounding environment


and satellites via a high-performance air interface.To prevent this vision from turning into a mere future scenario, we are already deeply involved in the automobile ecosystem of tomorrow. We develop the underlying transmission technologies for various application scenarios and supply data transmission and distribution solutions.



Optimization of the data transmission technologies is achieved by developing reliable wireless and broadcast connections that support the mobile communication applications. To ensure ideal distribution of the data in the vehicle, we create high-speed bus systems for broadband automotive networks.
