Empirical Evaluation of Bit Rate and Latency in a Private 5G Cell for Slow-Speed Vehicles in an Urban Environment

5G was developed a few years ago to support various verticals, including connected vehicles. Now that commercial deployments of 5G networks are available, it is crucial to empirically evaluate their performance in real-world scenarios. This study measures the performance of a private 5G campus network for a connected car in terms of downlink (DL) and uplink (UL) bit rates, as well as latency metrics including round-trip time (RTT) and jitter. The car is driven at controlled speeds of 10 km/h, 20 km/h, and 30 km/h on an urban street. Subsequently, we analyze the impact of speed on the probability distributions of these performance metrics. Notably, our observations suggest that 5G performance slightly improves at higher speeds. We attribute this to increased spatial diversity, as higher speeds enhance the likelihood of experiencing stronger received signal power levels across diverse locations.
