C-V2X Sidelink

5G NR Cellular V2X PC5 Sidelink

Direct device-to-device communication interface allowing vehicles and roadside units to communicate without cell towers.

Technical Explanation

Cellular Vehicle-to-Everything (C-V2X) utilizes the PC5 sidelink interface to enable direct, peer-to-peer radio communication between vehicles (V2V), pedestrians (V2P), and roadside infrastructure (V2I) in the dedicated 5.9 GHz ITS band, operating even when cellular coverage is absent.

Key Functions

  • Enables direct peer-to-peer wireless communication over PC5 interface
  • Operates independently of cellular base station coverage in 5.9 GHz band
  • Delivers ultra-low latency safety telemetry between vehicles and road sensors
