Overview
Product overview
Roadside V2X unit supporting interoperable C-V2X and DSRC communications for connected transportation deployments.
Technical foundation
Technologies
Cellular V2X
Supports TechnologyC-V2X
Cellular Vehicle-to-Everything is a communications technology that allows vehicles to exchange safety, traffic, and mobility information with other vehicles, infrastructure, pedestrians, and cellular networks.
Cooperative Intelligent Transport Systems
Supports TechnologyC-ITS
Cooperative Intelligent Transport Systems allow vehicles, infrastructure, traffic systems, and road users to share information for safer and more efficient transportation.
Dedicated Short-Range Communications
Supports TechnologyDSRC
Dedicated Short-Range Communications is a low-latency wireless technology designed for direct vehicle, roadside infrastructure, and transportation safety communications.
Edge Computing
Supports TechnologyEdge Computing processes transportation and vehicle data close to where it is generated, reducing latency and supporting faster V2X safety and mobility decisions.
ITS-G5
Supports TechnologyITS-G5
ITS-G5 is a European short-range communications technology used by cooperative intelligent transport systems for direct vehicle and roadside communications.
LTE-V2X
Supports TechnologyLTE-V2X
LTE-V2X is the initial cellular V2X generation based on LTE technology, supporting direct vehicle communications and network-assisted V2X services.
