Evolving Wireless Vehicular Communication System level comparison and analysis of 802,11 p, 4G 5G

In a vehicular environment, accurate and real-time weather information and forecast with, road condition information are key elements when improving the road safety. The vehicular communication can be conducted with short-range vehicular networking, based on IEEE 802. lip. Nowadays also cellular communication with 4G and upcoming 5G have been considered as vehicular communication media. In this paper, we are comparing the measurements conducted with IEEE 802.11 p, to the similar measurements with 4G and 5G pilot network. We performed a set of communication scenarios of IEEE 802.11 p based ITS-G5 and 4G/5G networks. We used the 5G test network based on LTE Release 14, 4G (LTE) and IEEE 802.11 p communication for system level performance analysis of latency, data rate, and throughput from the infrastructure and end user device perspectives. The outcome of our comparison shows that the state-of-the-art 5G radio interfaces are better alternative to meet majority of the requirements for vehicular applications e.g., mobility, latency, throughput, coverage and data rate.
