Project proves: Networked vehicle applications need fast computer access
Multi-Access Edge Computing (MEC) is a key technology to enable secure networked driving. This is the most important result of the Car2MEC project after two years of intensive testing and field trials by Continental, Deutsche Telekom, Fraunhofer ESK, MHP and Nokia on the A9 “Digital Autobahn” test field.

In the project, hybrid communication units from Fraunhofer ESK enabled time-critical applications for networked vehicles with established, standardized protocols and message formats. A highly efficient distributed messaging service (GeoService) implemented on the Multi-Access Edge node provided low-latency connectivity between vehicles and a direct connection to localized services. In combination with adaptive network algorithms from Fraunhofer ESK, which select the most suitable communication path in real time, the complementary strengths of different technologies can be used to provide an optimized Quality of Service (QoS) for each application and context.

"This project gave us the opportunity to evaluate our ETSI ITS-compliant hybrid solution in a commercial mobile network and to optimize it through 5G taking into account new possibilities," explains Karsten Roscher, research associate at Fraunhofer ESK. "While the edge cloud improved end-to-end latency by more than 20 ms, the 4G wireless access network remains a limiting factor for more sophisticated future services. But we're convinced that the combination of Edge Cloud and 5G will create completely new networked and distributed applications."

MHP provided insights into the value of MEC for networked driving from a business perspective. The consultancy identified critical success factors for potential commercial ecosystems based on the new technology. The economic opportunities opened up by MEC for the automotive industry are unclear on the one hand and promising on the other. Several possible fields of action were identified in the project. In addition to standardisation and a clear value proposition for the commitment of each individual investor, cooperation and partnerships are seen as crucial for future development.

Olaf Kleindienst, Partner at MHP, comments: "Everyone talks about the networked car and in a way the networked car already exists. But the fully networked car still has a lot to do and many questions still have to be answered. The fully networked car is a new environment for the automotive industry and the large, established players have to reinvent themselves to a large extent, even with new business models. We see projects such as Car2MEC as an excellent opportunity to think ahead, to discuss questions about this new environment at an early stage and to shed light on the topic from different perspectives."
