Cross-border 5G connectivity will warn vehicles of danger, no matter where you roam
Deutsche Telekom and Ericsson are taking the 5G show on the road — literally. The companies are showing how cross-border 5G connectivity can be used to warn autonomous vehicles of road dangers across national borders.
DT and Ericsson have been working together on various 5G projects, from developing sustainable 5G radio site operations to demonstrating the use of 5G end-to-end network slicing for video streaming. Now the companies are working on connectivity services as part of the European Union 5GCroCo (Fifth Generation Cross-Border Control) initiative. The companies demonstrated 5G communication at the border between Germany and France and also between Germany and Luxembourg.
The cross-border 5G connectivity is managed by Orange and POST networks in Luxembourg and Deutsche Telekom’s network in Germany. For the EU-funded cross-border 5G communication project, the existing 5G RAN sites were integrated with additional mobile network equipment from Ericsson to establish a 5G trail network.
There have been continuous technological breakthroughs in autonomous vehicles, but car manufacturers have been struggling to provide greater accuracy to anticipate dangerous events on the roads. These autonomous vehicular systems are equipped with hundreds of edge sensors to get a deeper understanding of the vehicle’s surroundings. This can trigger emergency braking and dangerous driving maneuvers.
Stellantis and Renault provided vehicles equipped with Anticipated Cooperative Collision Avoidance (ACCA) service to enable receiving warnings of road hazards. The ACCA service runs on mobile edge computing cloud infrastructure which is embedded in the mobile networks to provide low latency communication and enhanced edge computation for mission-critical applications.
The ACCA service detects the location of the road hazards by analyzing cloud information that is transmitted by the vehicles in the vicinity. Vehicles approaching the road hazards will be warned in advance using precise information about the vehicle environment. This aims to avoid dangerous driving maneuvers such as emergency braking.
But what if a car starts decelerating in one country while crossing into another? Data exchange between vehicles can’t stop at the border of Germany, France or Luxembourg. That’s the problem that DT, Ericsson showing progress in solving.
