C-V2X vs DSRC: what will prevail?
Without requiring line-of-sight to communicate, V2X allows direct real-time information exchanges between vehicles traveling at high speeds, in high-density traffic and even outside of mobile network coverage
Collectively known as vehicle-to-everything (V2X), these communication technologies encompass vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), as well as vehicle-to-network (V2N) communication. V2X will likely complement on-board sensors by providing enhanced information (such as data from other vehicles) over a longer range. With various radar, lidar, camera and ultrasonic sensors, an ADAS-equipped vehicle can see what is immediately around it, but is unable to provide intelligence beyond the short-range environment covered by these sensors—an accident five kilometers away for instance. This is where a V2X communication-enabled vehicle can help, by informing oncoming cars about the accident site, which can then perhaps be avoided.
