Mobile Edge Computing used to support live tests of assisted driving

Continental, Deutsche Telekom, Fraunhofer and Nokia Networks say they have demonstrated communication between vehicles via the LTE cell network with latencies of less than 20 milliseconds.

The companies carried out demonstrations of assisted braking and co-operative overtaking using Mobile Edge Computing technology to site application software on compute platforms co-sited at LTE base stations.

For the demos, a section of the Deutsche Telekom network was equipped with “cloudlet” MEC technology from Nokia Networks, and upgraded with position-locating technology developed by Fraunhofer ESK. This combination delivered signal transport times between two vehicles of less than 20 milliseconds.

Continental supplied the interface to the cars’ on-board systems via the CAN bus and the tablet application software. Fraunhofer ESK developed the GeoService software, which ensures that the vehicles’ position data is recorded and processed directly at the LTE base station.

The demonstration, which falls under DT’s 5Ghaus technology accelerator, was the first project carried out as part of the “Innovation Charter for the digital A9 motorway test bed”.
