Cellular V2X: Sidelink Diretto PC5 e Coordinamento di Rete Geografica Uu

Cellular-V2X stabilisce l'architettura di telecomunicazione per veicoli intelligenti, integrando LTE-V2X Rel-14/15 e 5G NR Sidelink Rel-16/17 in chip multimodo.

Velocità del sidelink diretto combinata con la copertura cellulare nazionale

Il C-V2X stabilisce un paradigma ibrido: il sidelink PC5 diretto offre una latenza inferiore a 10 ms per la prevenzione delle collisioni critiche, mentre l'interfaccia cellulare Uu collega i veicoli ai centri di gestione del traffico.
