Abstract

This article focuses on reviewing the results of a series of trials conducted in Europe and China to benchmark 5G’s benefits for automated driving challenges. The measurements have been conducted for studying the influence of the current 5G/LTE-V2X connectivity and optimizing antenna height, driving speed, and performance variation due to landscape variation. The results have been aggregated in real-world testing conducted in Finland and China. The vehicles have been equipped with onboard units (OBUs) and the infrastructure with the latest available 5G or LTE technologies.

The outcome of this study indicates that LTE-V2X highly depends on antenna height. However, the latencies are quite stable, being 20–50 ms unless line-of-sight connection is lost. The communication range is increased by 5G, and also
package size can be increased by up to 1 MB without increasing the package error rate, which in the LTE-V2X case starts increasing when 0.5 MB is exceeded. This is not a problem for traditional C-ITS messages, but if considering “see through” or “remote video operation,” then the package size demand is much higher and goes beyond LTE-V2X’s capacity.
