Porsche, Continental, Telcos, Institute Conclude Edge Connectivity Testing

Porsche’s IT consulting subsidiary MHP and Continental have concluded testing of edge computing as an enabler of vehicle connectivity.

The automotive giants carried out the testing as a joint project, Car2MEC, with Nokia, Deutsche Telekom, and the Fraunhofer ESK research institute on the section of Germany’s A9 autobahn designated as an autonomous vehicle testing track. Bavaria’s Ministry for Economic Affairs funded the project.

The researchers said the goal was to assess potential technological and economic benefits of edge computing for connected vehicles. Scenarios on which Nokia’s edge computing technologies were trialed included “emergency warning”, “end of jam warning”, “variable speed limit assistant”, and “HD maps”.

Deutsche Telekom provided infrastructure for the project. A Nokia statement said the testing area “shared resources with the LTE live network”. It added that Fraunhofer ESK provided a distributed messaging service, GeoService, which enabled communication between the test vehicles and “localized services”.

Fraunhofer ESK senior scientist Karsten Roscher claimed the tests showed edge computing “improved end-to-end latency … [but] the 4G radio access network is still a limiting factor” and 5G would work better with edge technologies. However, this followed the European Commission’s suggestion that 5G will play a minor role in its V2X strategy.
