Cellular V2X
Cellular V2X (C-V2X) is an umbrella term that comprises all 3rd Generation Partnership Project (3GPP) V2X technologies for connected mobility and self-driving cars. It includes both direct and cellular network communications and is an alternative to 802.11p, the IEEE specified standard for V2V and other forms of V2X communications.
Cellular V2X uses 3GPP standardised 4G LTE or 5G mobile cellular connectivity to exchange messages between vehicles, pedestrians, and wayside traffic control devices such as traffic signals. It commonly uses the 5.9 GHz frequency band, which is the officially designated intelligent transportation system (ITS) frequency in most countries. C-V2X can function without network assistance and exceeds the range of DSRC by about 25%.
C-V2X was developed within the 3GPP to replace DSRC in the US and C-ITS in Europe.
In 2014, 3GPP Release 13 spurred studies to test the applicability of the then current standards to V2X. This resulted in the 3GPP Release 14 specifications for C-V2X communications, finalised in 2017. 3GPP Release 15 introduced 5G for V2N use-cases and 3GPP Release 16 includes work on 5G NR direct communications for V2V/V2I.
In Europe, the EU announced in July 2019 that it was adopting a technology-neutral approach to C-ITS, leaving the way forward for 4G, 5G and other advanced technologies to be part of V2X applications and services.
In the United States, the Federal Communications Commission proposed late in 2019 that 20 MHz and possibly 30 MHz of the 5.9 GHz band be allocated to C-V2X. In November 2020, this proposal was accepted, and the upper 30 MHz (5.895–5.925 GHz) were allocated to C-V2X.
After a slow start linked to the slower-than-expected roll-out of 5G cellular networks, there were more than 50 C-V2X devices on the market in the first half of 2024.
