Globally, the 5.9 GHz frequency band is widely adopted for Internet of Vehicles (IoV) applications. This paper presents V2I channel measurements at 5.9 GHz in urban environments. Using measurement data, we extract key channel characteristics, including large-scale and small-scale fading. We analyzed statistical properties of these parameters and compared the effects of different transmitter antenna heights on channel characteristics. The results show that as antenna height increases, path loss decreases and multipath effects weaken, but reflections and interference from buildings become more significant. The findings of this paper are valuable for designing and optimizing communication systems, particularly in determining optimal base station heights in urban environments.

摘要

Globally, the 5.9 GHz frequency band is widely adopted for Internet of Vehicles (IoV) applications. This paper presents V2I channel measurements at 5.9 GHz in urban environments. Using measurement data, we extract key channel characteristics, including large-scale and small-scale fading. We analyzed statistical properties of these parameters and compared the effects of different transmitter antenna heights on channel characteristics. The results show that as antenna height increases, path loss decreases and multipath effects weaken, but reflections and interference from buildings become more significant. The findings of this paper are valuable for designing and optimizing communication systems, particularly in determining optimal base station heights in urban environments.
