Qualcomm have introduced a new cellular vehicle-to-everything (C-V2X) system that aims to improve road safety by accelerating the introduction of connected and autonomous vehicles (CAVs).
C-V2X’s overarching technologies encompass two transmission modes of direct and network-based communications, which are designed to serve as key features for safety conscious and autonomous driving solutions, while complementing other Advanced Driver Assistance Systems (ADAS) sensors, such as cameras, radar and lidar, to provide information about the vehicle’s surroundings, including non-line-of-sight scenarios.
C-V2X direct communication is designed to support active safety and helps enhance situational awareness by detecting and exchanging information using low latency transmission in the globally harmonised 5.9GHz ITS band for V2V (vehicle-to-vehicle), V2I (vehicle-to-infrastructure), and V2P (vehicle-to-pedestrian) scenarios without the need for a SIM (Subscriber Identity Module), cellular subscription, or network assistance.
Complementing direct communication transmissions, the network-based communication is designed to use the wireless operator’s 4G and emerging 5G wireless networks for V2N (vehicle-to-network) comms, and operates over licenced operator spectrum to support telematics, connected infotainment, and a growing variety of advanced informational safety use cases.
