C-V2X – the mobile industry’s contender
C-V2X is the new name for the V2X standard that was initially launched as LTE-V2X by respected international mobile communications standards body the 3rd Generation Partnership Project (3GPP), in its 3GPP Release 14. The change of name reflects the fact that C-V2X now promises an upgrade path from LTE to the much anticipated 5G mobile standard.
For device-to-device mode direct communications, C-V2X uses the same 5.9 GHz spectrum as DSRC and C-ITS. However, C-V2X devices can also operate in traditional mobile bands to communicate with the mobile network in so-called vehicle-to-network (V2N) mode. C-V2X device-to-device communications do not require a SIM card, a mobile subscription or any mobile network infrastructure.
C-V2X is a much younger technology than either DSRC or CITS, and is still under development, but early tests have shown that at the data rates required for V2X applications C-V2X reaches a range comparable to DSRC’s 300m at urban driving speeds and achieves 20-30 percent better range at faster speeds.
