Ettifos is a South Korea-based, 5G-focused V2X (vehicle-to-everything) company building the communication layer that lets cars, roadside infrastructure, and pedestrians exchange safety and traffic data in real time. Its flagship SIRIUS platform uses a software-defined modem that can switch between LTE-V2X and 5G-V2X with a software update, and its plug-and-play V2X-AIR onboard unit brings standards-compliant connectivity to both new and existing vehicles.
