In recent years, two main technologies have emerged and have hit the market for vehicular communication: one belonging to the Wi-Fi family, based on IEEE 802.11p, and the other built on cellular networks and standardized by 3GPP starting from Release 14, commonly referred to as Cellular-V2X (C-V2X). The automotive industry is currently experiencing a phase of uncertainty due to the lack of clear regulations regarding which standards and technologies should be adopted for vehicular com- munications. While the United States appears to favor C-V2X, following the FCC’s latest Report and Order, which reserves only the last three channels of the 5.9 GHz band exclusively for C-V2X use, Europe has adopted a technology-neutral stance.
